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. EupUhecia sp. 

 Order Lepidoptera ; family PuALiENlD.E, 



This caterpillar was beaten from the hemlock at Providence, Septem- 

 ber 19. 



Larva. — Head ronnded, 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™">. 



14. The 10-lined pine inch-worm. 

 Order Lepidoptera; family Phal^nid.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, behind 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 IS^^"'. 



Feeding on the hemlock in the grounds of the Butler Asylum, Provi- 

 dence, Rhode Island, September 18, 1883.

 The body is provided with seven lozenge-shaped pale patches centered 

 with dark. Length 37'"™.
