Description: Rust/orange, black & white pruinosity, which forms distinct markings, such as a line of white dots down the dorsal side of the abdomen. Sounds like N. tremulus. Has a call that sounds like a rapid series of clicks.
Habitat notes from ANNOTATED LIST OF COLORADO CICADAS by Wm T. Davis 1
Dr. Raymond H. Beamer, in an account of his collecting trip in Kansas in 1916, writes that dorsata was the most widely spread and abundant species taken. It was commonly found on low shrubs or weeds and grass, often on barren hill tops.
Megatibicen dorsatus is arguably the most beautiful cicada in the United States. Even it its teneral (meaning soft) form right after molting, in is visually impressive.
These three photos were taken by Greg Holmes of a Megatibicen dorsatus in its post-molting, teneral state.

Megatibicen grossus (Fabricius, 1775) aka Northern Dusk Singing Cicada. It’s the biggest cicada in North America!
FYI, the name of this cicada is changing to Megatibicen grossus (Fabricius, 1775). See: Sanborn, A.F.

Description: The largest North American cicada. Olive green to rusty brown with black, tan and white coloring. Heavy white pruinosis. M on mesonotum typically partially ocluded by pruinosis. Sings at dusk.
Song and morphological descriptions by Wm. T. Davis from MISSISSIPPI CICADAS, WITH A KEY TO THE SPECIES OF THE SOUTHEASTERN UNITED STATES1
Its song is monotonous in tone and not loud, considering the size
of the insect. It often commences to sing late in the afternoon and continues off and on until dark.
A. Large, heavy bodied species ; head broad, uncus simple, and first cross vein in the fore wings starting from radius 3 far back, or about one third distant from base of first marginal cell.
BB. Uncus broad at the base, triangular in shape and generally about as broad as long. Opercula broad and rounded at the extremities; no definite black area on the central part of the abdomen beneath, usually unicolorus.
EE. Wings broad, hind margin of the pronotum or collar green or greenish and more than 2 mm. broad.
F. Anal cells or membranes at base of fore and hind wings gray. Dorsal segments of the abdomen not margined with brown ; in fresh specimens the basal segments pruinose, also the terminal segments, leaving the four middle segments black. A large species expanding over 110 mm.

Locations from Wm. T. Davis’ MISSISSIPPI CICADAS, WITH A KEY TO THE SPECIES OF THE SOUTHEASTERN UNITED STATES1
Prof. R. W. Harned has contributed the following note : “In regard to the distribution of Tibicen vitripennis I am inclined to think that this insect will only be found on low ground or in swampy places. This insect seems to be fairly prevalent in what is known as the delta section of Mississippi or the Yazoo-Mississippi Delta. This is the alluvial western part of the state. This species is also fairly abun- dant in* similar soils in Arkansas and Louisiana. The first time that I ever noticed this species was late in June, 1912. I found them quite numerous in fields at Palmyra Island, south of Vicksburg. I was surprised to find them coming out of the ground several hundred yards away from any perennial plants. They were also emerging from soil that had been under water a few weeks before. The spe- cies is quite common in the cotton fields of the delta.”
The distribution seems to be confined to the central United States. Specimens have been examined from Mississippi, Louisiana, Arkan- sas, Oklahoma, Kansas, Nebraska and Indiana.
Key to Species:
AA. Small species; uncus wish-bone shaped, and first cross view in the fore wings starting from about the middle of the first marginal cell.
GG. First and second cross veins of fore wings not clouded, wings clear throughout and expanding about 70 mm.
Head proportionately smaller than in the last; front more pro- truding;- collar not so contrastingly colored and fore wings narrower vitripennis (Say).
A visual description from Wm. T Davis’ NOTES ON CICADAS FROM THE UNITED STATES WITH DESCRIPTIONS OF SEVERAL NEW SPECIES 2
What we have identified as this species is an insect with green in its coloring as mentioned by its describer; not entirely orange and black as in Cicada eugraphica from further west.

Descriptions from Wm. T. Davis’s NOTES ON CICADAS FROM THE UNITED STATES WITH DESCRIPTIONS OF SEVERAL NEW SPECIES.1
Note: Diceroprocta olympusa (Walker, 1850) = Cicada sordidata Uhler, 1892 & Cicada milvus Walker, 1858, in case that isn’t clear. 🙂
Cicada sordidata Uhler, was described in the Transactions of the Maryland Academy of Sciences, 1892, p. 175, from two males from Southern Florida. We figure a male from Big Pine Key, Fla., Sept. 19, 1913, that has been compared with one marked ” S. Fla.” in Uhler’s collection in the United States Nat. Museum, and labeled in his handwriting” Cicada sordidata.” This was no doubt one of his types. His published description is very full and among other things he says that the first three apical areoles of the fore wings “including the veins and cross veins smoke-brown.” This is subject to some variation, though the first and second cross veins are always clouded in mature specimens. He says ” Opercula short, pale, but little more than one-third the length of the abdomen, narrowing toward the tip, and rounded there ; the tips widely separated by a wedge-shaped space ; the drums completely covered by an inflated segent, with a wide interval between, which is occupied at the outer end by a smooth hump. The raised smooth line thus begun is con- tinued back upon the succeeding tergal segments, and from each prominence a grooved line extends outwards to the border of the segments.”
Cicada olympusa Walker was described in 1850, but no locality was given. It has been credited to North America by Distant. The description would seem to cover Cicada sordidata which is of the same size and we have been unable to find any other species in collections that fits it so well. Walker says in part ” scutcheon of the fore-chest [prothorax] adorned with four black stripes; the middle pair long, widened on the fore border and on the hind border ; the outer pair short and slightly curved; furrows and sides blackish; hind scutcheon [hind margin or collar] green, widened, rounded and adorned with a large pitchy mark at the base of each fore-wing, nearly straight on each side : scutcheon of the middle chest [mesonotum] adorned with four obconical black stripes; inner pair short with tawny borders; outer pair much longer, excavated into eight separate parts ; a large black spot with a black dot on each side be- tween the inner pair and the cross-ridge . . . fore borders of the [abdominal] segments adorned with pitchy interrupted bands; overduct ferruginous : drums pale tawny, very small, far apart ; inner sides pitchy.”
If it is meant that the extremities of the opercula are far apart then the above description agrees with sordidata, in which, however, the upper and inner edges of the opercula touch or nearly so.
Cicada milvus was described by Walker in 1858 from a single female from the ” United States ” and has been placed by Distant as a synonym of Cicada olympusa. Walker describes milvus as reddish tawny and says in part : ” Prothorax with four black stripes, the inner pair approximate, connected by a short black band in front, the outer pair very near the borders; two black discal dots; hind border greenish. Mesothorax with four conical black stripes, the inner pair short, the outer pair much intersected. Abdomen with an interrupted black band on each segment. Wings vitreous; veins pale green, black towards the tips. Fore wings with the first and second transverse veins clouded with dark brown.” The wings are said to expand 27 lines, that is about 57 mm.

Comments Off on Diceroprocta olympusa (Walker, 1850) aka Olympic Scrub Cicada
Descriptions from Wm. T. Davis from RECORDS OF CICADAS FROM NORTH AMERICA WITH DESCRIPTIONS OF NEW SPECIES1
Note: at the time Davis assigned Diceroprocta apache to the Tibicen Latreille, 1825 genus. It’s since been moved to Diceroprocta Stål, 1870.
Resembles Tibicen cinctifcra (Uhler), but has sharper pointed opercula, the outer sides of which are not parallel, but converge; is without the central pruinose spot at the base of the tergum, and instead of having the dorsal part of segment eight all pruinose, the whitened area is reduced to two spots with a black space between. In the allotype the plates that correspond to the opercula of the male, are sharper pointed than in cinctifcra, the double notch in the last ventral segment is usually deeper, the terminal spine is more robust, that is, has a broader base, and the abdomen is less tapering at the extremity. In the three types of Uhler’s cinctifcra in the United States National Museum, the costal margin of the fore wing is bright orange to the end of the radial cell, also the hind margin of the pronotum or collar, whereas in apache the color is light yellow or straw-color. The membranes at the base of both pairs of wings are orange or at least usually much darker than in apache, where they are white or light gray. Some of these differences in strudture and color are more clearly brought out in the illustrations.

A description of the Cacama cicadas from CICADAS OF THE GENUS CACAMA, WITH DESCRIPTIONS OF SEVERAL NEW SPECIES1:
In Cacama the tympanal coverings in the male entirely conceal the orifices, which is also the case in the genus Tibicen, but the head including the eyes is much narrower in Cacama, being little more than two thirds the width of the mesonotum. The abdomen is broad and much rounded behind ; in Tibicen it is more tapering. The apical areas of the fore wings in Cacama are eight in number, the two lowermost small and somewhat square in shape. In Tibicen the two lowest apical areas are not as nearly of the same size, the seventh being much smaller than the eighth.
Specifically about Cacama valvata:
Mr. Woodgate writes of the valvata he sent from Jemez Springs, N. M., that they were very shy and often found about the bush cactus. Some he took in the evening while they were at rest on the cactus. “They are the only insects except ants that can settle on the bush cactus without impaling themselves. The toughest beetles become impaled when they settle on this cactus and the ants proceed to eat them, but these Cicadas that have a very swift flight, can settle with impunity.” He says that “their song is not sustained for more than about two minutes in the brightest sunshine even.”

Description: Primarily either orange/rust or pea green, brown, black with heavy pruninosity which forms distinct markings on dorsal side of body. Dorsal side has two black stripes framed by three areas of pruinosity. Sounds like N. pronotalis.
The description comes from Wm. T. Davis’ document A NEW VARIETY OF CICADA RESEMBLING C. DORSATA. from September, 2015, published in the Journal of the New York Entomological Society. Vol. 23: 161-164.
Markings resembling those of C. dorsata [now M. dorsatus], but marginata var. dealbata is more green in color and has less black about the central area of the pronotum. The mesonotum is marked as in dorsata but is more pruinose ; the turgum has a dorsal line of white spots as in dorsata, but the sides are broadly pruinose and the posterior margin of each segment is narrowly edged with greenish yellow. Beneath both insects may be of the same color, though dorsata is usually much darker. The opercula are about as broad as long and broadly rounded at the tips. The fore wings in dorsata are oval in shape with the inner side (radius) of the costal margin blackish ; the veins are heavy and thickened, and the W-mark is prominent, whereas in luarginata var. dealbata the fore wings are more acuminate in form, the costal margin is green, darkened beyond the middle of the wing and the W-mark is not conspicuous or is wanting. One of the greatest differences between the two insects is in the genitalia. The uncus in dorsata viewed at full face is narrow and the piece below into which it locks is broadly notched with the extremities rounded. In var. dealbata the uncus is more nearly triangular in shape and the lower piece is narrowly notched with the extremities much produced. The male type of var. dealbata is figured.
Length of body 35 mm. ; length of fore wing 46 mm. ; expanse of wings 105 mm.
William T Davis’s description from A New Cicada from Arizona:
Resembles Cicada marginata Say [now called Megatibicen pronotalis walkeri Metcalf, 1955] in size, color, and markings. Head black with an oblong greenish yellow spot each side between the eyes and a small spot of the same color on the front just above the transverse rugae. Pronotum greenish yellow with a large, conspicuous black spot occupying the fore part of its central area. The hind margin of the pronotum (collar) is entirely unicolorous as in marginata. The mesonotum is black, with a pruinose band each side at the base of the wings; the elevated x is greenish yellow, and there are two conspicuous, irregularly formed (pipe-shaped) greenish yellow spots occupying its central portion. The tergum is black, each side broadly margined with pruinose, and the segments have their posterior margins yellowish. There is also an indication of a dorsal line of pruinose spots on the tergum, which in the type have been nearly worn off. Beneath the head is blackish, the remainder of the insect being greenish yellow and more or less pruinose. The costal margin of the fore wing is entirely greenish yellow, darkened beyond the middle, and the w-mark is inconspicuous. Both fore and hind wings are greenish-yellow at base, with the veins darkened beyond the middle.
