70. Tortru sp. 
Larva. — Body slender, tapering quite regularly towards each end; head jet black; 
prothorax brown black; body behind a lit tie lighter, with three dorsal whitish lines, 
the median the narrowest, the outer including the black waits : ■ lateral interrupted 
pale lin«\ and below a brown whitish raised Line, with a black dot on each segment ;

71. Tortrix sp. 
Larva. — Pale pea-green, dotted with white, larger and stouter than the black 
Tortrix, of the usual form; head and prothorax clear pea-green of the same color at 
tin- rest of the body : the warts arranged as usual, but pale green and very distinct, 
and appearing as whitish green spots; the hairs on tin; end of the body very long. 
Length 12""". Eats holes irregularly. Pupa in a folded leaf August 28.' 
Thr moth appeared September 2. 
Two TaohinflB came out August 29. 
72. Tortrix sp. 
This was found eating the upper surface off a folded and curled leaf, 
leaving a great blotch. Brunswick, Maine, September 14. 
Larva. — Head reddish, broad, and much flattened; on each side in front a broad 
conspicuous white line continuous with the front edge of the clypeus ; below the line 
on the side is a black line ; antennas white at base. 
Cervical shield large aud broad, green like the rest of the body, with a lateral 
black line; body rather flattened, pea-green, a little dusky along the back; the 
suture quite distinct, paler green than the rest of the body. Length 18 mm . 
73. Tortrix sp. 
This insect folds and crumples the leaf, much as does the Aphis on 
the same tree, forming a thin silken cocoon in the bottom of the fold. 
It avoids the light when the leaf is unfolded and 
is very active in its habits. 
Larva. — Body tapering a little before, and especially pos- 
teriorly ; head not quite so wide as the body; like the pro- 
thoracic shield, dusky umber color: body pale amber, with 
large conspicuous black piliferous warts ; sutures distinct, 
but the segments are not prominently wrinkled ; only one 
posterior distinct wrinkle. The warts are situated in a 
very short broad trapezoid aud one lateral wart is seen 
from above. Thoracic feet black. Length 5 mm . 
74. Tortrix sp. (Fig. 177.) 
Feeding on the leaves, folding over a leaf longi- 
tudinally in the middle, September 18, at Provi- 
dence, the following Tortricid caterpillar was 
found. It appears to hybernate as a larva, and, 
after repeated attempts, I have been unable to 
rear it: 
Larva, Body very narrow, sleuder cylindrical; head narrow and small, honey-yel- 
low : body tapering to the tail from behind the middle. The segments quite convex, 
with four dorsal large fleshy tubercles close together on the back of each segment, and 
two on each side, giving rise to slight hairs. The body is of a very dark olive-green. 
Length, ll mm .
