The name Couperi will nevertheless stand for this species; for 

 Mr. Edwards has recently called my attention to the fact that in 

 describing Pembina he stated it to be allied to the Californian 

 Pheres Boisd., while in the same connection he described a Califor- 

 nian butterfly {Behrii) as belonging to a distinct series of which 

 Lygdamus Doubl., was the type. The insect, therefore, which we 

 have been calling Pembina cannot be that species, and hence this 

 northern Glancopsyche was described for the first time by Mr. 

 Grote. What the true Pembina is, remains to be determined. 



The southern Glancopsyche, called Lygdamus by Doubleday, is 

 probably distinct from Couperi. I have not yet detected any dif- 

 ferences in the abdominal appendages of the males, but that is 

 hardly to be expected, since in these parts the distinction between 

 closely allied species in the Ephori is always exceedingly slight; 

 southern specimens of Glancopsyche, however, differ from the 

 northern, in having a more glossy reflection of the upper-surface in 

 the males, a narrower dusky border of the same in the f.-males, and, 

 in both sexes, a paler tint on the under-surface, and a tendency to 

 much larger spots, in which the black central portion predominates. 



A specimen of this species in my collectit)n (from Kanawha Co., 

 W. Va.) has the right fore wing longitudiually crumpled in a slight 

 degree, the fold passing along the middle of the cell; beneath, a 

 little before the extremity of the cell, and also a little before the 

 second sub-marginal spot, is a small roundish black spot, almost 

 Avholly overlaid by a powdering of blue scales, of the color of the 

 upper-surface, as if there were a partial inversion of the upper- 

 surface, caused by the fold.
