HEMLOCK CATERPILLARS. 875 
uated on the hinder edges of the second and third segments from the 
head ; but nearer the middle in the segment next to the head. All the 
abdominal segments covered with fine whitish warts, giving a sha- 
greened appearance to the skin. The lateral raised line very promi- 
nent; the body not being thick, but appearing as if partly shriveled 
below a dusky lateral stripe. Supra-anal plate large, broad, flat, sub- 
triangular. On the underside of the body a median dusky linear stripe, 
on each side of which the body is whitish. Two faint dusky subdorsal 
lines, one on each side. This caterpillar, as it occurs on the hemlock, 
varies a good deal ; some examples being transversely banded with 
brownish-red, giving them a checkered appearance. 
13. Eupithecia sp. 
Order Lepidoptera ; family PhaL-ENID.e. 
This caterpillar was beaten from the hemlock at Providence, Septem- 
ber 19. 
Larva. — Head rounded, slightly bilobed ; as wide as the body, which is smooth, not 
granulated, the segments distinctly wrinkled ; lateral ridge quite distinct. Head and 
body yellowish green, next to the sutures straw yellow ; no distinctive markings. 
Length 16 mm . 
14. The 10-lined pine inch- worm. 
Order Lepidoptera; family Phal.enid.e. 
This was also found on the hemlock at Brunswick, August 27. 
Head rounded, bilobed, the lobes a little prominent above, but 
scarcely angular ; fully as wide as the body ; reddish brown, with a 
dark transverse diffuse band across the vertex, and fine wavy dull 
brick-red transverse stripes. 
Body moderately thick, with no humps or tubercles, but transversely 
wrinkled ; general color dull brick-red brown, with lighter lilac and 
whitish markings. This larva may at once be recognized by a series of 
large dorsal lozenge-shaped whitish-lilac spots, behiud each of which is 
a pair of black dots inclosing a conspicuous white one. The fourth of 
these lozenge-shaped pale lilac spots enlarges into a pale patch sur- 
rounding the body. Beneath, pale lilac passing in the middle into a 
livid greenish tint. Supra-anal plate rounded, rough with piliferous 
tubercles ; anal legs broad and long. Length 18 mm . 
Feeding on the hemlock in the grounds of the Butler Asylum, Provi- 
dence, Khode Island, September 18, 1883.

15. The red and yellow striped pine span-worm. 
We have observed a caterpillar on the hemlock September 29, which 
belonged to this species, but was larger than any 1 had before observed, 
The body is provided with seven lozenge-shaped pale patches centered 
with dark. Length 37 mm .
