in the series of si)ecimens before n)e there is little \ariation, except 

 in s1/e ;ind intensity of the iiround color. As the laKei- deepens the 

 simple markings are more relie\"e(l, and in such cases we note a \ ague 

 ]iale shade indicating the course of the t)rdinary lines. In one speci 

 men, received from .Mr. W.N. Tidlaiit, ('olumbus, Oiiio, the central 

 si)aceof the i)riinaries is considerably i)aler than the other parts of the 

 wing, and in a Delaware specimen the terminal space is (]iiite ob\ ioiisly 

 darkened. 



In this spet;ies the lateral bristles of the male antenna' are well 

 marked and tpiite long, and the thickening at basal third involves four 

 Joints. Ot these, three bear stout spines inwardly: the two lower and 

 shorter bear each of them two, of which that nearest the tip is stoutest, 

 \\ hile the third and longer joint bears a single process basally. In the 

 female the anteniue arc clothed with rough scales and with scarcely 

 prominent lateral set;e. The fore legs of the male are furnished with 

 moderate tuftings only. The cavity of the coxa is filled by elongated 

 scales. The femur contains no evident tuftings, while the tuft beneath 

 the tibial process is sparse. 



The species is the most common of those belonging to the first series 

 and is represented in most collections. It is in this, also, that Ave find 

 the most marked tendency toward a bunching of the veins, arising from 

 the accessory cell of ])riinaries.
