134 Tryon Reakirt on Coloradian Butterflies. 



tinged with black towards their apices : grayish portions of secon- 

 daries tinged with violaceous, which also covers all the abdominal area, 

 below the cell; two or more sub-marginal jet black spots near the 

 outer angle. 



Below, the veins of the secondaries are much more dilated and 

 greenish — the sub-marginal band, very prominent — giving the appear- 

 ance of two concentric curved macular rows, and a central cellular 

 elongate spot, all white, upon a dark-greenish ground : expanse 1.88 

 iuches.

I have never seen this species, nor am I aware of its being contained 

 in the cabinet of any American Entomologist.

I do not believe in this locality, or that it can be considered an 

 American species. Apart from the very great difference of geographi- 

 cal distribution, out of perhaps the largest collections of Rocky Moun- 

 tain Lepidoptera ever formed, (those belonging to the Entom. Society, 

 TV. H. Edwards, Esq., and myself,) I have failed to detect any species, 

 which might, even by careless examination, be construed into this. 

 Its nearest American congener is P. Occidentalis, m ; but I have 

 proved most satisfactorily by a comparison of specimens, and as will 

 also be readily perceived by the fore given description, that they are 

 specifically distinct.

I am unable to discover auy specific differences between Poey's 

 Felicia, of which I have examined his original examples, and those 

 found within the United States; I have therefore treated it as a
