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.”
Diceroprocta cinctifera is found in North America, specifically the south-western United States and Mexico. There are three subspecies. It was formerly known as Cicada cinctifera. Yes, its name has changed

Proarna genus description by W. L. Distant:
Characters. — Head (including eyes) about equal in width to base of mesonotum. eyes scarcely projecting beyond anterior angles of pronotum, vertex of head at area of ocelli distinctly longer than front; pronotum a little shorter than mesonotum. the posterior angles a little prominent but not lobately produced; abdomen about as long as space between apex of head and base of cruciform elevation; metasternum with a moderately elevated transverse central plate, which is not anteriorly angularly produced ; tegmina about three times as long as broad, the transverse vein at base of second apical area more or less vertical ; wings about half the length of tegmina, the latter with eight apical areas, the basal cell longer than broad.
