GRAPTA III. 
ginous streaks; the pattern of markings as in male hut faint and nearly lost in the 
groundcolor; some individuals light, the yellow predominating; in others the 
ferruginous streaks give color to the whole surface; sub-marginal black spots less 
conspicuous, and sometimes on disc of primaries wanting; marginal lunules as in 
male but less distinct; silver spot as in male, but sometimes a mere line not 
thickened at extremities. 
Mature Larva. Length 1.25 inch. Color pale green marked with 
greenish white at the base of each spine with lines of same color across each seg- 
ment; head dull pink covered with short spines and having at upper angle on each 
side a large branching spine pink at base, black at tip; a black patch on either side 
of face; mandibles black; body furnished with seven rows of many branching yellow 
spines, each branch tipped with black; under side green; legs reddish brown, pro- 
legs green; spiracles black; on the 8th to 11th segments inclusive an orange spot 
immediately anterior to each spiracle. 
Chrysalis delicate white, not much clouded, the wing cases and whole front 
having a sheen of bronze; the abdominal tubercles bronze. Or the general color 
is pale brown, clouded with darker shades, not metallic except on the tubercles; 
the palpi cases are long and sharp, and the prominence on back of head is pointed. 
In size and general form the chrysalis resembles that of Comma. 
I have occasionally taken this species at Coalburgh, AY. Va. and in the Catskill 
Mountains and was formerly inclined to regard it as a variety of either Comma or 
Interrogationis. During the season of 1870 I was fortunate in obtaining two 
of its larvae and from them the butterflies. They were feeding on the hop, 
in July, and in habit resembled the larvae of Comma, remaining concealed on 
the under side of a folded leaf, and eating from the outer extremity so long 
as enough remained to afford protection. These larvae were nearly mature and 
shortly after changed to chrysalids. In this state they continued ten days and 
yielded one male and one female butterfly, the white chrysalis producing the female. 
This species is between Comma and Interrogations. The shape is that of the 
latter as is also the shade of color of upper side. On the under side of the male 
the markings are rather nearer Comma but with a difference in coloration. The 
under side of the female differs materially from that of either species. 
Note. — While the foregoing description was passing through the press, be- 
tween the 10th and 18th May (1871), I took eight larvae of Dryas from the hop, 
from half grown to mature. The younger ones were dull white, with an interrupt- 
ed supra-stigmatal blackish line; as they approached maturity this disappeared and 
the color changed to green. Between 20th Alay and 2nd June emerged 6 $, 1 $.
