The localities of each, have been indicated after its specific name. 



Papilio Asterius. Cramer. 



Hab. — (Western) — Rocky Mts. Colorado Territory. (In my Col- 

 lection). 



Two specimens, collected in the heart of the mountains, appear to 

 differ in no respect from more eastern examples. Mr. Riding reports 

 them as cpuite abundant. 



Papilio Indra. nov. sp. 



Hab.— Pike's Peak, Colorado Terr.. (Coll Ent. Soc. Phil.). 



JUali\ Upper surface, deep blackish brown ; expanse 2. ^S-o. 06 inches 

 Two macular yellow bands on both wings, one below the cell, and the 

 other submarginal, very near to Asterius. On the anterior wings, 

 those of the outer row are not so much rounded as in that species, but 

 flattened lunes; while the triangulation in the inner row is not so 

 marked, the spots nearest the inner margin, losing this characteristic 

 almost entirely : in the second from the costa of these, there is a small 

 rounded black dot; a narrow yellow line indicates the discal arc: 

 fringe black. 



Posterior wings, have the spots of the mesial band more closely 

 united, and no detached yellow mark within the cell, as in Asterius; 

 the submarginal lunules are also narrower than in that species; a 

 series of imperfect crescents of shining bine atoms, extends from the 

 costa to the anal margin between the two bands, the last, alone well 

 defined, surmounts a large, bright, rufous, anal spot, containing a 

 large black point, and situated upon the anal indentation; emargina- 

 tions, yellow ; the tail of Asterius is represented by a short, obtused 

 prolongation, about a line in length. 



Under surface, the yellow spots upon the primaries remain the same 

 color, but are much enlarged, forming two continuous bands, divided 



* The existence of two of these in America is very hypothetical.
