408 FIFTH EEPORT OF THE ENTOMOLOGICAL COMMISSION. 



43. Hypena sp. 



This caterpillar occurred on the rock maple September 10, at Jack- 

 sou, N. H. 



Larva. — Body loug and slender, cylindrical ; five pairs of abdominal legs, the first 

 pair half as large as the third and fourth pairs; the anal legs long and slender. 

 Head pale-greenish, with a livid tinge and lineated with numerous meandering, 

 brownish, broken, sinuous lines. Body tapering somewhat from the seventh ab- 

 which a lateral dominal seg ment. Two slight tubercles on the eighth abdominal 

 segment, from ridge passes down in front of the spiracles. Length, 30'"'". 



44. Pandemis lamprosana Robs. 

 Order Lepidoptera ; family Tortricid.e. 



Among the leaf rollers upon the maple, collected May 10, was one of 

 which we kept no description, which resulted in an imago of Pandemis 

 lamprosana. (Forbes' Third Et. Ins. Illinois.) 



45. The oblique-banded leaf-roller. 



Caccecia rosaccana Harris. 



This nearly omnivorous species (not hitherto reported, however, from 

 the maple) was found by Forbes (Third Rt. Ins. Illinois) rolling the 

 leaves of Acer dasycarpum in May. The pupse and larvae collected on 

 the 20th of that mouth, emerged from July 9 to 13. 



46. The maple leaf-cutter. 



Incurvaria acerifoliella (Fitch). 



Order Lepidoptera; family Tineid^. 



Cutting round holes in the leaves and consuming their pulp in rings and semi-cir- 

 cular spots, and using the round pieces to hide the small white worms between them 

 and the leaf, forming a broad round case adhering to the surface of the leaves. 



This larva with its singular case has been described by Fitch, and 

 we have received specimens of maple leaves and cases from Vermont. 

 Early in August the leaves of forest trees begin to wither, and holes 

 appear in them, the orbicular pieces being taken by the little worm to 

 form a broad scale concealing it. The worms fall with the leaves to the 

 ground in the autumn, and there remain transforming iu their cases, 

 and late in the spring appear as moths. 



The larva. — Nearly a quarter of an inch loug ; slender, cylindrical, soft, and con- 

 tractile; dull white; head flattened, and like the three succeeding segments, pale 

 rusty brown. 



The moth with long narrow-pointed wings ; the fore pair brilliant steel-blue, the 

 hind wings smoky brown, with purplish reflections. Between the antennte a dense 

 tuft of erect bright orauge-yellow hairs. (Fitch.)
