402 ADDENDA. 



apex of fore wings ; palpi as in Numitorj but the third 

 joint longer ; abdomen surpassing hind wings, but less 

 so than in Numitor ; the whole insect more robust than 

 Numiior. 



Fore wings brown, darker than in Numitor, with- 

 out the discal yellow patch, emitting a pale-blue sheen 

 in reflected light ; a few yellow scales below the costa 

 between the venules, and a few scattered on the base 

 of the wing, but in either case not enough to give a 

 yellow color ; otherwise the wing is uniform brown. 

 Hind wings marked and colored as in Numitor ; yellow, 

 with outer and costal borders and base brown, the brown 

 along internal margin running to a point before reach- 

 ing anal angle. 



Under side differing very little from the under side 

 of Numitor ; the dark central and posterior area of fore 

 wings a little darker brown, the costal and outer 

 margins yellow, the yellow running to a point before 

 reaching the posterior angle. Hind wings uniform 

 yellow. 



Antenna black, annulate with white; club black, 

 tipped with brown— the club of Numitor is tipped with 

 black ; palpi white at sides, black above, terminal joint 

 black; thorax concolorous with fore wings, abdomen 

 concolorous with hind wings. 



The above description is drawn from a single speci- 

 men taken at Ridgeland, near Chicago, September 6, 

 1896, by Mr. W. E. Longley, in whose cabinet it is 

 and after whom I have named the species. In de- 

 scribing the species I have compared the specimen with 

 Numitor because that species is so common all over this
