506 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



70. Toririx sp. 



Larva. — Body slender, tapering quite regularly towards each end; head jet black; 

 prothorax brown black ; body behind a little lighter, with three dorsal whitish lines, 

 the median the narrowest, the outer including the black warts ; a lateral interrupted 

 pale line, and below a brown whitish raised line, with a black dot on each segment ; 

 body warted much as usual. Length 11™'". Brunswick, August 11-14. 



71. Tortrix sp. 



Lrtrra.— 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 as 

 the rest of the body ; the warts arranged as usual, but pale green and very distinct, 

 and appearing as whitish green spots ; the hairs on the end of the body very long. 

 Length I'S™"". Eats holes irregularly. Pupa in a folded leaf August 28. 



The moth appeared September 2. 



Two Tachinae 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; antennae white at base. 



Cervical shield large and 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™™. 



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, 

 btit the segments are not prominently wrinkled ; only one 

 posterior distinct wrinkle. The warts are situated in a 

 very short broad trapezoid and one lateral wart is seen 

 from above. Thoracic feet black. Length 5™™. 



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, slender 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, 11""".
