DESCRIPTION. 
Larva,. (PI. II., fig. 1, 3.)—'The general appearance of this 
larva is that of a dusky, somewhat hairy caterpillar, paler be¬ 
neath, with a reddish brown head, darker in the middle, and 
variegated cervical shield. The principal hairs are conspicuous¬ 
ly long and slender. 
The head is brown, with a lateral black blotch behind the 
eyes, smooth, much darker on the slightly depressed frontal 
area, this bordered by depressed black sutures, outside which, 
at a little distance, is a V-shaped line white line. Antennae 
three-jointed; first joint very large, broadly conical; second 
thick,'oval, with a very long stout hair at outer side of tip; 
the third minute. Ocelli five, black, placed behind the antennae 
in a curve opening downward. 
Labrum broadly emarginate, with rounded lobes. Maxillae 
and labium pale beneath, with dark sutures strongly contrast¬ 
ing with adjacent parts of the head. Mala and palpi brown. 
Labial palpi minute. Maxillary palpi three-jointed, large; first 
joint nearly as thick as the palpiger, and about as broad as 
long; second joint cylindrical, width two thirds the length; third 
joint tapering, about two thirds as long as the second. 
Body with six conspicuous rows of long pale hairs, longest on 
the posterior segments, one hair of each row to each segment, 
each borne on a minute black piliferous tubercle scarcely as large 
as the spiracle. One row above spiracles, another equally dis¬ 
tant below, and two subdorsal rows. Other smaller hairs irregu¬ 
larly distributed. 
Cervical shield yellow, smooth, with a few scattered hairs and 
two curved brown blotches, one on each side, separated by a 
yellow median spot. Anal plate coriaceous, brown, heart- 
shaped, with six long stout hairs at its posterior margin. Pos¬ 
terior segments without spines or tubercles at hinder margin, 
differing here from the peach borer. Spiracles black, nearly cir¬ 
cular, anterior pair but little larger than the remaining eight, 
last pair not exceeding the eighth in size. 
Thoracic legs pale reddish brown externally, paler within, with 
dusky tips. Each proleg except the last pair with a complete 
close circlet of large hooks, and several smaller ones besides, 
and also a horny black central disk or tubercle within the ring. 
Last pair with a single half circlet of very strong close-set 
hooks. 
Imago. (Plate II., fig. 5.)—Expanse 20 to 25 mm. Head and 
thorax dusky gray with bright bronze reflections. Abdomen simi¬ 
lar, and also brightly bronzed, but with edges of segments pale 
Fore wings light gray, with brownish red and black markings 
Posterior two thirds of basal field brownish red, with scattered red¬ 
dish scales along the costa also, the reddish tint deepest along the 
middle of the wing. Basal line near the middle of the wing 
white, sometimes obsolete posteriorly, making, when complete.
