576 FIFTH REPORT OF TIIF ENTOMOLOGICAL COMMISSION. 
Two spun their cocoons about .June 13, producing the moths June L'7: 
others occurred July 2. 
Larva, — Body green, the sutures yellowish when the caterpillar is in motion; no 
well marked cervical shield; a dark-colored dorsal line; an indistinct light-colored 
bI Igmatal line ; head and body beneath pale green ; spiracles riuged with pale brown. 
gtb, ID""", .?«'. inch. (Coqnillett.) 
Moth. — Head and palpi choeolate brown. Thorax varying from Bream color to 
ocherons, and sometimes stained with brownish. Collar and tip- of the not of a 
brownish color. The fore wings are of the same color as the thorax from the base 
out to the oblique band across the middle of the wing, except the portion below 
the fold, which is clouded with dark fuscous and brown, and a tuff of dark brown 
scales on the basal third of the fold. The oblique band which starts from the middle 
of the costa and terminates within the anal angle is of a light reddish brown color, 
and has a row of scale-tufts along its inner edge. The apical portion of the wing is 
of the same color as the band, though sometimes clouded with brown, while the 
space between is somewhat paler than the baud, especially on the costa, where it 
approaches the color of the basal part of the costa. The fringes are of the same 
color as the outer part of the wing, except at the anal angle, where they are of a dull 
smoky color. The hiud wiugs are pale yellowish, tinged with fuscous towards the 
apex. The fringes are lighter than the wiugs, but with a somewhat darker basal 
line. Abdomen, pale fuscous. The under side of the fore wings is pale ocherous, 
mottled or clouded with fuscous. Under side of the hind wings colored as above, 
but with a few fuscous sprinkles towards the apex. Expanse of wings, from 10 to 
\6 mm . (Fernald, manuscript.) 
44. The willow teras. 
Teras vibumana Clemens. 
The caterpillar of this common species is of the ordinary shape and 
green in color, occurring on the willow in Maine during August. The 
specimen we reared changed to a chrysalis August 19 ; remained in that 
condition a little over two weeks, namely, until September 7. The moth 
has been determined by Professor Fernald. 
Larva. — Greenish. 
Pupa. — Body slender; end of the abdomen flattened aud excavated, with two large 
lateral hooks before the tip. Length, 8 mm . 
Moth. — Head, thorax and fore wiugs rust-red. Head above aud front of thorax 
deep rust-red, hinder edge of the thorax bright red. Fore wings rust-red, deeper on 
the costa; a dusky patch at the base; beyond, on the inner third of the costa. is a 
broad, paler, square spot, succeeded by a long, dark, deep reddish-brown patch, 
which extends to neat the apex. The rest of the wing is clearer and paler, ash-col- 
ored, mixed with brick-red scales. In the middle of the wing on the inner third are 
two distinct, twin, fine black dots. Beyond are three black dots, forming an obliqne 
line, extending from the median vein to a little beyond the middle of the hinder 
edge of the wing ; a few scattered, black, line dots near the outer edge of the wing. 
Fringe broad, reddish externally, dark on the basal half, and grayish on the inner 
angle of the wing; hind wiugs uniformly gray slate-colored; abdomen dark brown, 
paler at the tip. Expanse of wings, I6 mm (.70 inch.) 
45. Grapholitha galla-Balidana Riley. 
In the Transactions of the St. Louis Academy of Science for 18S1 
(p. 320) Professor Riley described this gall-inhabiting caterpillar from 
two specimens which emerged June 17, from galls on willow twigs, at
