transverse line distinct, obtusely angulated opposite the reniform 
spot, the posterior boundary of which it reaches, thus running obli¬ 
quely to the posterior margin. At the angle of this line is an ob- 
scure reddish shade which invades the reniform spot. 
Posterior transverse line broader than the others, oblique, nearly 
black. Between this and the subterminal line is a purple shade, 
heaviest inward. The latter line is irregularly scalloped, being den¬ 
tate on the veins. A slender terminal line ; fringes purple whitish at 
base, costa with two oblique white marks in the vicinity of the 
transverse line or between that and the subterminal. 
Fringe of posterior wings white, slightly tinged with purplish; 
under surface of both wings pale yellow, with purple shades corres¬ 
ponding to those of the upper surface, and a purple spot representing 
the reniform. 
DISTRIBUTION AND LIFE HISTORY. 
This species has been reported from Canada to Pennsylvania and 
Illinois, occurring in the last throughout the whole State. Speci¬ 
mens found upon blackberries, May 28, pupated about June 15 and 
commenced to emerge on the 5th July, the last of this lot appear¬ 
ing August 21. Another specimen entered the earth July 10, and 
emerged on the 18th August. With Prof. French of Carbondale, 
larvae obtained early in June had all entered the earth on the 19th, 
and emerged from August 5 to 81. On the other hand, larvae of 
Pyrrhia angulata (not impossibly identical with this) obtained by 
Coquillet from smartweed (Polygonum pennsylvanicum) September 15, 
entered the earth on the 27th and disclosed the imagos on the 22d 
May of the following year, and a few days thereafter. It is conse¬ 
quently possible that this species is two brooded. 
INJURIES TO VEGETATION. 
The injuries to vegetation noted thus far, are confined to the 
worthless plants Desmodium and Polygonum, and to the rose and 
the blackberry. By Prof. French, in Jackson county, the young 
larvie, when about half an inch in length, were noticed eating and 
disfiguring roses, feeding within the flower rather than on the out¬ 
side, and seeming to prefer the bases of the petals. 
At Normal, as already mentioned, the larvae were found only upon 
the blackberry, devouring the leaves. The damage was occasionally 
decidedly serious, in some cases nearly every cane bearing one or 
more of the larvae. These were feeding upon the tender leaves near 
the ends of the stalks, in company with Oxyptilus delavaricus.
