Wm. T. Davis description

Neotibicen latifasciatus was described in 1915 by Davis in the article Notes on Some Cicadas from the Eastern and Central United States with a Description of a New Variety of Cicada Pruinosa in the Journal of The New York Entomological Society. 1

Smith and Grossbeck say of the specimens they had from the coast of New Jersey and which we now know to be a variety: “Abdomen above black, base of first segment with a white, heavily pruinose lateral dash, which encroaches to some extent upon the second segment; a similar but longer and broader lateral dash extends along the base of the third segment and a spot of the same color is on each side of the eighth segment. In the female the dash of the second segment differs from that of the male in not becoming attenuated dorsally, but in being squarely truncated.”

For the variety thus described with the broad white lateral dashes on segment three, we propose the name of latifasciafa. We then have Cicada pruninosa [now Neotibicen pruinosus] as described by Say, with the tergum entirely black or nearly so, with the attenuated white stripe at the lateral base of the third abdominal segment, being the form common from Indiana, Missouri, Nebraska, Kansas, etc., of which we figure a male from Chetopa, Kansas ; Cicada pruinosa var. latifasciata so far known only from the coastal region of the eastern and southern United States, with the broad stripe on segment three and abdomen beneath more shining black, of which we figure a male from Cape May Co., New Jersey, and Cicada pruninosa var. winnemanna [now Neotibicen winnemanna] with the hind margins of the abdominal segments more or less fulvous, the second segment having the band broader than the others and a white streak generally hardly discernible each side at the base of the third segment, of which we figure a male from Plummer’s Island, Maryland. The females of these cicadas have the charactertistic markings far less distinct than in the males and occasionally some are entirely absent.

Identification key by Wm T Davis2

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.

B. Uncus longer than broad. Black species with green or greenish markings and black area on the central part of the abdomen beneath, except in sayi, and new variety of davisi.

C. Hind margin of pronotum or collar, green or greenish.

Dorsum of abdomen shining black with a broad pruinose mark each side on segment three ; blackened area on under side of abdomen more in the nature of an even stripe.
pruinosa var. latifasciata (Davis.)

Neotibicen davisi aka Davis’ Southeastern Dog-Day Cicada

Neotibicen davisi aka Davis’ Southeastern Dog-Day Cicada.

There are two sub-species of Neotibicen davisi, and it makes sense to discuss both on the name page.

  • Neotibicen davisi davisi (Smith and Grossbeck, 1907). Quick ID: it has black on its abdomen.
  • Neotibicen davisi hardeni Davis, 1918. Quick ID: it lacks the black on the abdomen, and is only found in Arkansas and Mississippi.

In this photo, N. davisi hardeni is on the left, and N. davisi davisi is on the right:

Identification keys by Wm. T. Davis from MISSISSIPPI CICADAS, WITH A KEY TO THE SPECIES OF THE SOUTHEASTERN UNITED STATES. 1

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.

B. Uncus longer than broad. Black species with green or greenish markings and black area on the central part of the abdomen beneath, except in sayi, and new variety of davisi.

C. Hind margin of pronotum or collar, green or greenish.

Neotibicen davisi hardeni Davis, 1918:

Abdomen greenish centrally on under side, blackened area
wanting, marginal cells of fore wings clouded.
davisi var. harnedi new variety.

Neotibicen davisi davisi (Smith and Grossbeck, 1907):

An irregular band of black on the under side of the abdomen, head rounded in front ; a rather small species.
davisi (Smith & Grossbeck).

Description of Neotibicen davisi hardeni Davis, 1918 1:

Tibicen davisi var. harnedi new variety, PI. VII, fig. 4.

Type male, Helena, Arkansas, June, 19 16 (K. D. Jacob). Davis
collection.

Allotype female, Rodney, Jefferson Co., Miss.. August, 1917 (O.
A. Hammett). Collection, Miss. Agri. and Mechanical College.

More robust than typical davisi, with broader wings, the first seven marginal cells of the fore wings being clouded much as in Tibicen superba Fitch. The dorsal markings are quite green in color, the central, green, wedge-shaped mark on the pronotum is not sepa- rated from the hind margin, but is confluent with it; the collar is bright green. The dorsal surface is less rusty in appearance than in typical davisi. Beneath the abdomen is greenish, without the “narrow black portion in the center,” as in typical davisi.

Location and song notes 1:

davisi occurs throughout the southeastern states as far north as New Jersey. Its song- is a continuous z-ing of short dura- tion, and is more sharp in tone, though not as loud as that produced by the larger, related black species.

Identification notes from Notes on Cicadas from the United States with Descriptions of Several New Species by Wm. T. Davis

This document compares canicularis, davisi, and aurifera. Identifying any of the green/black Neotibicen can be vexing, so these details help.

Canicularis has the central area shining black and ex- tending in the form of an irregular band to the end of the abdomen.

In canicnlaris the collar is green with its front margin often edged with black.

NEW SPECIES by Wm T. Davis

Cicada figurata Walker.

This species was described [by Walker] in 1858 in List of the Specimens of Homopterous Insects in the collection of the British Museum, Supplement, p. 19. Unfortunately no locality was given. The description in part is as follows: ” Black, mostly tawny beneath. Head with a large tawny spot on each side in front between the eyes. . . . Pro- thorax reddish, black in front and behind, with a double tawny stripe; border tawny, with a black streak on each side. Mesothorax with four oblique tawny stripes; the middle pair recurved inward; the lateral pair enclosed at each of their tips by a lateral tawny streak; sides and hind ridges tawny. Legs tawny. Wings vitreous. Fore wings narrow, much acuminated testaceous at the base, and with a testaceous streak along the sixth discoidal areolet ; primitive areolet black; veins piceous; costa testaceous to the tip of the front areolet; first and second transverse veins slightly curved, clouded with black.

Song and morphological descriptions by Wm. T. Davis from MISSISSIPPI CICADAS, WITH A KEY TO THE SPECIES OF THE SOUTHEASTERN UNITED STATES2

E. Wings long and narrow, collar 2 mm. or less in breadth at cen- tral portions ; dorsum of abdomen black or nearly so.

Basal cell of fore wings often black or nearly so, anal cells of both pair of wings yellowish. Expands about 100 mm figurata (Walker)

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.

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.

Classification:

Family: Cicadidae
