times having black centres, on primaries minute, except the two at the ends of the 

 row ; in the disc of secondaries, a white G, varying in form, but usually thick and 

 angular with each end sharp and barbed ; bodv above black, covered with oreenish 

 hairs ; below, brown grey ; antennae dark brown above, whitish below ; club black 

 with a yellow tip.

Hind margin of jirimaries less incised and the dentations, esj^ecially of sec- 

 ondaries, less prominent. Color of iqiper surface a shade more yellowish than in 

 male. The under side in some cases marked as in male, but of duller colors, and 

 the separate markings much less distinct. In most however the color is greyish- 

 brown, darker next base ; the submarginal lines and green spots showing faintly ; 

 the silver mark delicate, usually o^^en and like that of Prognc, but sometimes an 

 angular C. 



Larva unknown. 



This species is very common m the Catskill Mountains in the month of Au- 

 gust, frequenting the forest roads in comj^any with a few Progne and Comma, and 

 is of similar habits. It is deejDer colored than its allies and the black markings are 

 of greater extent, making it a conspicuous S2:)ecies. It is usually seen alighted on 

 the ground, and although alert and quick in its motions, may be captured without 

 difficulty. The sj^ecies is also common in the Adirondacks and White Mount- 

 ains, and probably throughout the northern part of the continent. I have received 

 it from Fort Simjison and from Rupert House, Hudson's Bay, and also from Nova 

 Scotia.
