THE CANADIAN ENTOMOLOGIST. 151 



Here belong, according to Edwards, two North American species, 

 Mandan Edw. and Omaha Edw., which last was separated by Scudder 

 (System. Rev. of Amer. Butterflies, p. 54) from Mandan into a genus, 

 Potanthus. 



Thymelicus. 



Antennae half as long as the fore-wings, with elongate-ovoid, coni- 

 cally-tipped club. Apical joint of the palpi nearly erect, moderately long 

 and slender, subulate, hidden to beyond its middle by the long, stiff hairy 

 clothing of the middle-joint Middle tibiae with a longitudinal series of 

 short spines. Hind-wings somewhat produced at the inner angle. Male 

 with a discoidal stigma, without a costal-fold, and without a tibial tuft. 



It differs from the next related genus Pamphila in the slender, subu- 

 late apical joint of the palpi and in the absence of the hooklet on the end 

 of the antennal club ( Pamph. Abides, in which the antennal hooklet is 

 curved, has a very short, thick, conical apical joint to the palpi). 



Edwards places here two North American species which are unknown 

 to me — Hylax Edw. and Garita Reak.* The Texan species, Waco 

 Edw., placed by Scudder in Thymelicus must, because of essential differ- 

 ences, form a separate genus, Copceodes,+ to which, according to Edwards, 

 Arenc Edw. also belongs. 



Pamphila. 



Club of antennae ovate, or elongated, on the end more or less curved 

 into a much thinner, acute hooklet, which may be shorter or longer, but 

 always shorter than the club itself. The length of the hooklet depends 

 upon the number of the antennal joints of which it consists (in the 

 American Phylceus Dr. it is represented by the single terminal joint which 

 sets upon the thick end of the club in the form of a short spine). Palpi 

 placed close to the front, at most extending a little beyond the eyes, the 

 middle-joint broad anteriorly, closely set with long, brush-like hair-scales ; 

 the apical joint conical, either short and thick, or moderately long and 

 more slender, yet not so thin and subulate as in Thymelicus. Tibiae
