veins. Similar bands accompany the radius, media, and cubitus. 

 Light areas occur in the interspaces between the main veins as 

 well as between some of the branches. Two conspicuous, large, 

 light spots, with irregular boundaries, occur in the apical part 

 of the wing. The agreement with the types of the species from 

 Richmond, Ohio, is very close. The two light spots on the 

 apical part of the wing are not described for the type, probably 

 because the apex was not well preserved. 



In the original description of E. benedicta, Scudder expressed 

 doubt as to its specific separation from E. maledicta. The dif- 

 ferences which seemed to distinguish the two forms were the 

 more arched costal border of E benedicta, the. less extent of 

 the cubital 'area, and the approximation in the point of origin 

 of the two radial branches. More than forty tegmina of this 

 species are at hand for comparison. Camera lucida sketches 

 of numerous wings show that, while those with a short cubitus 

 have, as a rule, a more arched border, there is an almost con-

tinuous series between, with no break sufficient to serve as a 

 specific character. Figures 26 and 27 show the extreme limits 

 in the extent of the cubitus, the two figures corresponding 

 closely to the type figures of the two forms. In one the cubi- 

 tus falls decidedly short of the apical margin, while in the 

 other it extends by an outward curve and more numerous 

 branches well on to this border. Other specimens show 7 

 that the cubitus is variable in extent, and individuals can be 

 found presenting a condition so nearly intermediate that a 

 specific separation can hardly be sustained on this character. 

 The third distinction given, the approximation in the point of 

 origin of the first and second radial branches, is not constant. 

 Occasionally a wing is seen having both a long cubitus and a 

 close approximation in the point of origin of the first and 

 second radial branches. 



Hind Wings. — The hind wings are thin, and ovate in shape. 

 The costa is submarginal, straight, and simple. The subcostal
