208 WM. n. EDWARDS. 



From a sinp^le specimen taken at South Apache, Arizona, by Mr. 

 Ilenshaw, in 1874. 



Some years ago Mr. S. H. Scudder undertook to revise the Hes- 

 peridge of North America, and did publish a list of generic names 

 adopted by him, in which the species were allotted to very restricted 

 and therefore very numerous genera. It has remained a bare list 

 however to this day. We have looked for a definition of these genera 

 so that the points upon which they are severally founded might be 

 apparent. In the absence of such definition, it is quite impossible to 

 determine to which genus, under this revisal, a given species may 

 belong, for the generic differences are in many cases evidently scarcely 

 more than specific, or at least, what would be deemed specific by most 

 systematists. I am obliged therefore, in giving names to new species, 

 either to ignore Mr. Scudder's arrangement altogether, which I do not 

 wish to do, provided he will show that they are properly founded, or 

 temporarily and until his definitions appear, fall back on the general 

 designation Hesperia, as I have done in this paper. Such genera as 

 Mr. Scudder has indicated, so far as they are undefined, properly have 

 no standing, and can be allowed to claim it merely by courtesy. 



Papilio Hippocrates, Felder. 



Var. Oregonia. — In 1873, Mr. Henry Edwards took, on the 

 Columbia River, a single female Papilio, which I can refer only to 

 the Japanese species, Hippocrates. It expands 4 inches. Felder de- 

 scribes this species as larger than Machaon, the yellow area narrower, 

 the wings narrower and more produced, the hind wings also shorter 

 on the costa and more produced posteriorly j the tails longer, the anal 

 spot more obscurely colored, and joined abruptly to the blue lunule ; 

 the black border of the hind wings on the under side broader, the 

 blue spots more distinct, and placed almost in the middle of the black 

 ground, the outer ones accompanied by few yellow atoms, and the cells 

 of both wings longer. And with some exceptions this female agrees 

 well with females of Hippocrates from Japan, with which I have 

 compared it. It bears much the same relation to Hippocrates as 

 Aliuska bears to Machaon.
