LAWSON: KANSAS CICADELLID^. 257 



Distribution: Should occur throughout the eastern portion 

 of the state wherever its host occurs. Specimens are at hand 

 from Douglas county. 



Hosts: Our specimens were all taken from Ampelopsis quin- 

 quefolia. Gillette records it as sometimes occurring on grape.

Erythroneura comes var. vitis Van D., Cat. Hemip. N. A., p. 713, 1917. 



Form: Like typical comes in size and structure. 



Color: Head yellow, vertex sometimes marked with reddish lines or 

 the base reddish. Pronotum with anterior portion yellowish, remainder 

 reddish or blood-brown, the lateral margins often brighter. Base of 

 elytra reddish, followed by a yellow transverse bar, back of which is a 

 large red spot which reaches the black spots on the costal margin, the 

 interior of this spot often being brownish-red. Back of this spot is an- 

 other yellow transverse band which reaches just beyond the red transverse 

 veins. The apex of the elytra is smoky with a black spot in the second 

 apical cell. 



External genitalia: As in typical covies. 



Internal male genitalia: Very much as in typical comes. The oedagus, 

 however, seems to show some differences, which, should further study re- 

 veal as constant, would justify us in advancing this variety to specific 

 rank. 



Distribution: Specimens of this variety have been taken in 

 Douglas, Pottawatomie and Riley counties. It of course has a 

 larger distribution in the state than this indicates. 



Hosts: Our specimens were taken on grape.

 elytron are three yellow spots around the reddish tip of the clavus.
