Gastropacba americana Harr. 



Sept. 18th, 1830. Found larva on trunk of the apple tree. Has sixteen 

 feet. Length two inches and a half, and the transverse and vertical diam- 

 eter are almost equal; body convex above, flat beneath. Hairy, but the 

 hairs disposed so that the colors of the body can be distinctly seen. Body 

 above ashen gray variegated with large, irregular, whitish spots, and finely 

 punctured above with black. A large, more conspicuous, triangular spot on 

 the sides of the fourth segment, the apex of triangle directed backwards. A 

 similar, fainter one on sides of sixth segment; both white. On the posterior 

 margin of the second and third segments is a transverse band of a beautiful 

 scarlet color with a black spot at each end and a smaller dot in the middle. 

 These transverse bands are not seen except when the insect is in motion 

 or stretches forward its anterior extremity. The under side of the body is of 

 a fine yellow color, with a black, lozenge shaped spot between each of the 

 membranous feet; a much larger spot including the fore feet, in each of the 

 first three segments, and a small one beneath the segments destitute of feet. 

 The true feet are jet black, and the spurious ashen colored with a black spot 

 near the bod}-. The head is ashen, with a depression on the front, and five 

 small black eyes each side. On the first segment are 'two conical tubercles 

 at each side, the lower pair being much the longest, and projecting ante- 

 riorly. Each subsequent segment has one tubercle on each side much 

 smaller, and progressively so to the last. Each tubercle is ornamented 

 with a tuft of hairs, also progressively shorter, the hairs being gray, and
