LAWSON: KANSAS CICADID^. 341 



times there is a suggestion of the two dark median triangles on the 

 anterior margin. Mesonotum yellownsh-green, marked with brown as 

 follows: Between the arms of the W, a large posteriorly tapering spot 

 on either side laterad of this, the tips of the anterior arms of the light 

 cruciform elevation, and two faint dots just cephalad of these. Ab- 

 dominal terga straw-colored, with the bases of the segments, especially 

 laterally, more or less marked with fuscous. The wings have the veins 

 straw-colored or greenish basally, becoming brownish apically. The ci'oss 

 veins between R3 and R4..1, between R4-0 and Mi, and between Mi and 

 Mo are sometimes slightly, but usually distinctly darkened, and there is 

 a tendency for all the veins to be slightly smoky apically. The basal 

 areoles of the fore wings are clear and the flaps of both wings are milky- 

 white to straw-colored. Beneath, the insect is straw-colored or yellowish- 

 green, with the opercula lighter. The legs are straw-colored with the 

 femora distinctly banded with fuscous. 



Form: The following are the measurements in millimeters of the speci- 

 mens at hand: 



Length of body 11 to 13 



Width of head 3 . 75 to 4 



Expanse of fore wings , . . . . 29 to 32 



Greatest width of fore wing 4 to 5 



Greatest width of operculum 2 to 2 . -5 



Greatest length of operculum 2.5 to 3 



The opercula are distinctly wider than long excluding the extension 

 beyond the coxal cavity. They are widely separated medially and are 

 broadly rounded from the cephalo-lateral angle to the angulate meso- 

 caudal angle which slightly overlaps the metasternum. 



Genitalia : Supra-anal plate of male with a very wide emargination 

 posteriorly. Viewed laterally there is a very strong and acute dorsal 

 point. The uncus, viewed laterally, enlarges apically and is bifid. Viewed 

 caudally it is narrowest basally, widest just below the middle, and ends in 

 four rounded lobes. The ventral piece consists of two very widely sepa- 

 rated arms which lie against the supra-anal plate. The last ventral seg- 

 ment of the male is about twice as broad as long and the truncate pos- 

 terior margin is very slightly emarginate medially. The pygofers of the 

 female have a small median tooth which does not exceed the sinuated 

 posterior margins. The last ventral segment of the female is about three 

 times as wide as long, the posterior margin being broadly emarginated 

 about one-third of the distance to the base, the sides of the emargina- 

 tion themselves being slightly notched. The lateral pieces of the ovi- 

 positor each bear two or three indistinct ridges which are followed by 

 four prominent teeth and these by three smaller and indistinct ones. 



Distribution: The only counties from which this species 

 seems to have been taken are Sumner and Barber. Van Duzee 

 records it from Texas and New Mexico. Accordingly Kansas 

 seems to be the northern limit of its range.
