CLEAR-WING MOTHS OF FAMILY AEGERIIDAE 195 



process; aedeagus long, slender, straight or nearly so. Female genitalia 

 with ductus short, slightly sclerotized below ostium and in most of the 

 species with a circle of short, longitudinal rods of sclcrotization before 

 the small, round bursa. 



A very distinct genus, not closely related to any other American genus, 

 comprising a group of species with identical venation and very similar 

 genitalia in both sexes. Because the species are exceedingly variable 

 in color and size, their differentiation is difficult and some of the applied 

 names may eventually prove to denote merely geographical races. All 

 the North American species, of which the food plants are known, are 

 borers in the roots and basal stalks of mallows.
