humeral margins fused with slightly concave posterior margin. Elytra 

 very long and narrow. 



Color: Whitish or pale yellow. Vertex pale yellow with large red 

 spot just back of apex. Pronotum with similar spot in the middle. Tip 

 of scutellum with large red spot. Elytra whitish, irregularly marked 

 with pale yellow or reddish spots and each with three large black spots, 

 the largest one just laterad of the middle of the clavus, one near the 

 middle of the costal margin, and one at the base of the inner apical cell. 

 A red spot also on the mesopleurae. Any or all of the red spots may be 

 entirely absent or present only as yellowish spots. 



Exter7ial genitalia: About as in conies. 



Internal male genitalia: Styles of the general form of the other mem- 

 bers of the genus but with the broad apex distinctly convex between the 

 two terminal teeth. Connective stout, broadly U-shaped; oedagus broad 

 basally, with a small Y-shaped dorsally directed process at about its 

 middle, and terminating apically in a large obtusely pointed process be- 

 low which are two slender acutely pointed and terminally diverging strap- 

 like processes. 



Distribution: While undoubtedly occurring over a large por- 

 tion of the eastern part of the state, the only specimens at hand 

 are from Douglas county. 



Hosts : This is a very common species in Douglas county on 

 grape.

 Erythroneura comes var. maculata Van D., Cat. Hemip. N. A., p. 714, 1917. 



Form: In size and structure like comes. 



Color: Yellowish with bright red spots. Vertex with apical red spot 

 and transverse band on disc which is curved strongly caudad medially. 

 Pronotum \vith two broad red lateral lines and a broader, often Y-shaped 

 median stripe. Scutellum with red lines on margins near the base and 

 a large apical spot. Elytra with three spots on clavus, the first two often 

 fused, five spots on corium forming a zigzag line, and the transverse 

 veins, red. Face marked with red above. 



External genitalia: As in comes. The chitinous process on the dorsal 

 margin of the pygofers is, however, entirely different. It is not U-shaped 

 as in comes, but consists of a long process which for most of its length 

 is not in the pygofer, and which ends in two widely separated prominent 

 teeth. This difference alone is enough to justify its separation from 

 comes. 



Internal male genitalia: Styles for the most part as in cotnes, but the 

 terminal or upturned portion is much larger, the preapical tooth on the 

 mesal margin being much further back. The terminal tooth is always
