Erythroneura comes var. octonotata ^^'alsh 



Erijthruneura octo-)iot(itn. Walsh, B. D. Prairie Farmer, Se])t. G, 1862, p. 

 149. [lUinois.] 



The essential part of Walsh's description is: "Elytra whitish 

 hyaline, with the same three spots as in the preceding [ziezae], 

 and in addition one on the inner margin not far from the base." 

 This variety, therefore, is an almost colorless form with four l)lack 

 dots on each tegmen; highly colored forms having these dots and 

 those having a black vitta on scutellum should be extended. I 

 have seen no specimen that exactly fits Walsh's description, but 

 he notes "I have examined some dozen specimens," so that it is 

 pro])able the very pale form he describes is common somewhere 

 in Illinois. 



Erythroneura comes var. accepta new variety 



With the black tegminal spots as in variety octonotata Walsh, and in addi- 

 tion, red color markings of the comes or vitifex type.
