LAWSON: KANSAS CICADID^. 317 



our specimens is entirely greenish-buff. Mesonotum of the same color 

 with black spots as follows: A pair between the arms of the W, a 

 small triangular pair laterad of these, a still smaller pair just above base 

 of fore wings, and a small spot mesad of the tips of the anterior arms 

 of the cruciform elevation. Abdominal terga not as green as the rest 

 of the body, with small pruinose spots laterally at the base of the first 

 segment and with the base of the second segment sometimes narrowly 

 black. The wings are distinctly smoky apically, the veins being olive-green 

 basally, becoming brown apically. The cross veins between R^ and R4+5 

 and between the latter and Mi are strongly and widely infuscate. The 

 basal areoles of the fore wings are greenish anteriorly. The flaps of 

 both wings are dark gray. Beneath the insect is brownish or buff and 

 entirely pruinose. The legs are of the same color as the underside, dis- 

 tinctly striped and slightly darkening apically. 



Form: The following are the measurements in millimeters of the 

 specimens at hand: 



Length of body 30 to 33 



Width of head 13.5 to 13 . 75 



Expanse of fore wings 86 to 90 



Gi-eatest width of fore wiiig 12 to 12.5 



Greatest width of operculum 6.5 to 7 



Greatest length of operculum 9.5 to 10 



The opercula are distinctly longer than wide, the lateral margins are 

 slightly sinuate, the mesal margins slightly overlap, and the posterior 

 margins are rounded but with the mesal portion distinctly longer and 

 straighter than the outer part. 



Genitalia : Supra-anal plate of male with a stout median tooth which 

 exceeds the rounded lateral angles. The uncus, viewed laterally, is dis- 

 tinctly curved and widens distally to the obtuse apex. Viewed caudally 

 it is a large sclerite nearly twice as long as wide, scarcely narrowing to 

 the broadly rounded apex, and with the usual depression on the dorsal 

 part of its caudal aspect. The ventral piece has its arms widely but not 

 deeply separated. The last ventral segment of the male is distinctly less 

 than tvdce as wide as long and is strongly rounded posteriorly. The py- 

 gofers of the female have a stout and rather short median spine which 

 exceeds the obtusely angulate lateral angles. The last ventral segment 

 of the female has the lateral margins distinctly sinuate, the posterior mar- 

 gin with a broad angular emargination which reaches half way to the 

 base. The lateral pieces of the ovipositor each bear at first five low 

 ridges followed by two prominent teeth and then about six small and 

 indistinct teeth. 



Distribution: The only record we have of the occurrence of 

 this species in the state is from Barber county. It seems to 

 be a distinctively southern species as shown by its distribution 

 as given by Van Duzee, who records it from Arkansas, Okla- 

 homa, New Mexico and Texas.
