LAWS'ON: KANSAS CICADID>E. 321 



The costal margin of the fore wings is slightly but distinctly bent 

 near the middle. The opercula are longer than broad. They slightly 

 overlap along their mesal margins, the lateral margins are sinuately 

 narrowed posteriorly and the posterior margin runs cephalo-mesad in a 

 straight line from the rounded lateral angles. 



Genitalia: Supra-anal plate of male with a very broad but short 

 median spine which scarcely exceeds the rounded lateral angles. Uncus, 

 when viewed laterally, is curved on its posterior margin to the semi- 

 obtuse apex. When viewed caudally it is a large sclerite less than twice 

 as long as wide and gradually tapering from the base to the broadly 

 rounded apex. The upper portion of the caudal aspect shows a large 

 triangular depression. The ventral piece is U-shaped with the arms 

 fairly deeply divided. The last ventral segment of the male is over 

 twice as wide as long, and slightly emarginate apically. The pygofers 

 of the female have a prominent and acute median spine which strongly 

 exceeds the strongly-angled lateral angles. The last ventral segment 

 of the female has the lateral margins sinuate and the posterior margin 

 broadly and angularly emarginate nearly one-half the distance to the 

 base. The lateral pieces of the ovipositor each bear about twelve teeth 

 or ridges, of which the median four alone are distinct. 



Distribution: The only Kansas records for this species are 

 from Sedgwick, Douglas and Clay counties, the former two 

 by E. S. Tucker and the last by Wm. T. Davis. Outside of 

 Kansas it is found in Massachusetts, New York, Michigan, 

 Tennessee, North Carolina, Illinois, and Mississippi, so that 

 Kansas would seem to be its western limit. 



Remarks: Davis says that the song of this species is a con- 

 tinuous z-ing, generally of a short duration. All the speci- 

 mens examined by the writer were from North Carolina.

A rather small species usually green and black but sometimes vary- 

 ing to reddish-brown and black, having the body covered with a golden 

 pubescence. Specimens at hand vary from 23 to 26 mm. in length. 



Color: Head black, with the following marked with greenish to 

 brownish: The antennal ledges and a broad spot between them and 

 the eyes, a median elliptical spot on upper portion of the front with 

 sometimes a spot caudad of this, spots at basal angles of the front, a. 

 spot laterad of each lateral ocellus, and irregular spots between thes*
