408 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
43. llyptna sp. 
This caterpillar occurred ou the rock maple September 10, at Jack- 
son, N. H. 
Lana. — Body long and slender, cylindrical : live pairs of abdominal legs, the first 
pair half as huge as the third and fourth pairs; tin* 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 doininal seg meut. Two slight tubercles on the eighth abdominal 
segment, from ridge passes down in front of the spiracles. Length, 30 mm . 
44. Pandemia lamprosana Robs. 
Order Lepidoptera ; family Tortkkid.k. 
Among the leaf rollers upon the maple, collected May 10, was one of 
which we kept no description, which resulted in an imago of Pandemia 
lamprosana. (Forbes' Third Rt. Ins. Illinois.) 
45. The oblique banded leaf-roller. 
Caccvcia 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 pupae and larva* collected on 
the 20th of that mouth, emerged from July 9 to 13. 
46. The maple leaf-cutter. 
Incurvaria acerifolieUa (Fitch). 
Order Lepidoptera; family Tixeid.e. 
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 begiu 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 autumu, and there remain transforming in their cases, 
and late in the spring appear as moths. 
The larva. — Nearly a quarter of an inch long; 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 antennas a dense 
tuft of erect bright orange-yellow hairs. (Fitch.)
