CLEAR-VVING MOTHS OF FAMILY AEGERllDAE 51 



distinct on structural differences in the male genitalia. Veins 10 and 11 

 of the forewings are coincident, as in ithacae. The male genitalia differ 

 by the shorter vinculum and by the arrangement of narrower scales on 

 the sacculus ridge, terminating at a shallow pocket without scales before the 

 margin of harpe. The female genitalia are much like those of C. ithacae. 



The species presumably is a root borer in Compositae in midwestern 

 and Canadian prairie regions.
