THE CANADIAN ENTOMOLOGIST. 95 



This larva varies somewhat in color, some specimens being of a paler green 

 than that above described. There are two broods of this insect in the season, 

 the larvce resulting from the eggs deposited by the second brood usually attain 

 to less than half their growth before winter, when they hybernate, complet- 

 ing their growth the following spring. 



Limenitis artîiemù, Drury. — About the middle of July, 1868, while beat- 

 ing some thorn bushes over an umbrella I captured a larva closely resembling 

 lJtsij)pus, in fact I thought at first it was merely a variety of that larva. 

 Upon further examination I suspected it to be distinct, and resolved to 

 describe it, but before an opportunity occurred of doing so it disappointed 

 me by changing to a chrysalis, which in ten or twelve days after produced a 

 beautiful specimen of Arthemis. 



Thecla acadica, Edwds. — Larva found feeding on willow, from lOth to 

 20th of June. 



Length five-eighths of an inch; onisciform. Head very small, pale brown 

 and shining, drawn within the second segment when at rest. 



Body above green, of a moderately dark shade, thickly covered with very 

 short whitish hairs scarcely visible to the unaided eye. Body thickest from 

 third to tenth segments. Dorsal line of a darker shade of green than the 

 rest of body. Dorsal region flat, rather wide, and edged on each side with 

 a raised whitish yellow line, beginning at the third segment, and growing 

 •fainter on the twelfth and thirteenth. «Sides of body inclined at an almost 

 acute angle and striped with faint oblique lines of greenish-yellow. A 

 whitish-yellow line borders the under surface, beginning at the anterior edge 

 of second segment, and extending entirely around the body to a point opposite 

 the place of beginning. This line is raised in the same manner as that 

 bordering the dorsal ridge. Twelfth and thirteenth segments much flattened^ 

 especially the latter. 



Under surface similar to upper, and also covered with very short fine hairs, 

 — feet and prolegs partake of the general color. 



In a younger specimen the head was almost black, with a streak of white 

 across the mandibles. The under side was rather deeper in color than the 

 upper, with a faint bluish tint. 



Chrysalis 0.32in. long; greatest width 0.15 in., covered with minute hairs, 

 pale brown, with many dots and patches of a darker shade. A dark ventral 

 stripe from seventh to terminal segments, sides of body with four or five short 

 dark lines. The insect remains in the chrysalis state about eight or nine 

 days. 



Thecla ? — Larva found feeding on pine, Juue 27th, 1865, one speci- 

 men full grown, another about one-third grown, probably the larva of Thecla 

 niphon, Boisd. & Lee.
