898 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
12. (itometrid larva. 
A large Geometrid was fouud on the hackmatack at Brunswick, 
August 30, which died in the breeding box. 
Larva. — Body large and thick cylindrical, marked exactly like a larch twig. Head 
rather small, J as wide as the body, llatteued, horizontal in position. Prothoracic 
segment a little wider than the head, smooth, not enlarged, but meso-segment is 
swollen in front, and especially on the sides,into a large rough lateral tubercle, which 
is warted, between the lateral tubercles is a transverse row of black warts. On the 
hinder end of each segment is a transverse ridge, ending on each side in a small wart. 
These ridges become larger toward the end of the body, especially the sixth abdomi- 
nal segment, on the succeeding segments the ridge is wanting, the lateral warts re- 
maining. The large anal plate is not regularly triangular, butends in four tubercles 
with two on top; the anal legs are not very wide, but the dorsal spines are very large, 
acute, and prominent. The sides of the legs are warted. The body is stone-gray, vari- 
ably marbled and mottled with black and white or pale gray, so as to closely resemble 
a light larch twig. The sides of the pro- and meso-rings are white ; -above on meso- is 
a short double white line ; the folds of the lateral ridges are marked with black, and 
there is a median black dorsal line extending from the third from the end to the end of 
the supra-anal plate. Under side gray, as above. Length 45 mm ; thickness of body 5 mm . 
13. Eupithecia sp. 
This larva was taken from a hackmatack June 25. 
Larva. — Much like the larva of E. palpata, but not so much flattened. Head rather 
full, as wide as the body ; rounded. Body pale pea-green, a little paler than the 
leaves on which it feeds. Suture and lateral line washed with straw (faint) yellow. 
Supra-anal plate broad, rounded, segments somewhat wrinkled transversely. Abdom- 
inal legs concolorous with the body. Thoracic legs greenish amber; hindermost pair 
dark amber. A slender, delicate-colored species. Length ll mm . 
14. Eupithecia sp. 
Another larva of this genus, with the body more cylindrical, occurred 
June 27 on the hackmatack. It also occurred June 23 on the spruce. 
In the latter specimen the body is deeper yellow, with the markings a 
little more distinct, but otherwise it agreed with the specimen described 
below. 
Larva. — The body is more cylindrical, but the head is shaped as in the larva of E. 
palpata. Head yellowish. Body of even width throughout, a little wider than head ; 
surface finely but distinctly granulated ; a broad, continuous, medio-dorsal brick 
red stripe ; a lateral narrow scalloped reddish-purple stripe. The space between the 
dorsal and the subdorsal lines more or less sutfused with purplish red and the sur- 
face sprinkled with yellow granulations. Body elsewhere yellow ; under side livid ; 
on each side a narrow pink- red stripe extending down the sides of the two pairs of 
abdominal legs. Supra-anal plate regularly triangular, scutellate ; beneath the apex 
are two large piliferous conical warts. Anal legs as in E. palpata, broad aud large. 
Length 12""". 
15. Eupithecia sp. 
This larva occurred July 10 to 25 in Maine ; pupating August 2. 
Several also occurred on the fir August 5 to 7, and were common on 
Pinus strobus. It begins to eat the ends of the leaves August 5. One 
of them on the latter tree spun a slight cocoon August 14. As unfortu-
