576 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



Two spun their cocoons about June 13, producing the moths June 27; 

 otlfers occurred July 2. 



Larva. — Body greeu, the sutures yellowish when the caterpillar is in motion; no 

 well marked cervical shield ; a dark-colored dorsal line; an indistinct light-colored 

 stigmatal line ; head and body beneath pale green ; spiracles ringed with pale browu. 

 Length, 19""", .7(j inch. (Coqnillett.) 



Moth. — Head and palpi chocolate brown. Thorax varying from cream color to- 

 ocherous, and sometimes stained with brownish. Collar and tips of the crest of a 

 brownish color. The fore wings are of the same color as the thorax from the base 

 out to the oblique baud across the middle of the wing, except the portion below 

 the fold, which is clouded with dark fuscous and brown, and a tuft of dark browu 

 scales on the basal third of the fold. The oblique band which starts from the middle 

 of the costa and terminates within the aual angle is of a light reddish brown color, 

 and has a row of scale-tnfts 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 band, 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 hind wings are pale yellowish, tinged with fuscous towards the 

 apex. The fringes are lighter than the wings, 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 16 to 

 IH""™. (Fernald, manuscript.) 



44. The willow teras. 



Teraa viburnana 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 iiattened and excavated, with two large 

 lateral hooks before the tip. Length, 8""". 



Moth. — Head, thorax and fore wings rust-red. Head above and 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 near the apex. The rest of the wing is clearer and iialer, 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 oblique 

 line, extending from the median vein to a little beyond the middle of the hinder 

 edge of the wing ; a few scattered, black, fine 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 wings uniformly gray slate-colored; abdomen dark brown, 

 paler at the tip. Expanse of wings, 18"^'" (.70 inch.) 



45. GraphoUtha gallw-saliciana Riley. 



In the Transactions of the St. Louis Academy of Science for 1881 

 (p. 320) Professor Riley described this gall-inhabiting caterpillar from 

 two specimens which emerged June 17, from galls on willow twigs, at
