GRAPTA I. 
times Raying 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, hut usually thick and 
angular with each end sharp and barbed ; body above black, covered with greenish 
hairs ; below, brown grey ; antennae dark brown above, whitish below ; club black 
with a yellow tip. 
Female. Expands 2.8 inches. 
Hind margin of primaries less incised and the dentations, especially of sec- 
ondaries, less prominent. Color of upper 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 open and like that of Progne, but sometimes an 
angular C. 
Larva unknown. 
This species is very common in the Catskill Mountains in the month of Au- 
gust, frequenting the forest roads in company with a few Progne and Comma, and 
is of similar habits. It is deeper colored than its allies and the black markings are 
of greater extent, making it a conspicuous species. It is usually seen alighted on 
the ground, and although alert and quick in its motions, may be captured without 
difficulty. The species 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 Simpson and from Rupert House, Hudson’s Bay, and also from Nova 
Scotia.
