I dorsal row of dusky diamond-shaped spots on the abdominal region ; on the thoracic 
segments three obscure parallel dusky lines, and on the supra-anal plate a dusky me- 
dian band extends forward to tin- last diamond-shaped spot. Length, 12 mm . 
Eupitheeia-like (itometrid larva. 
Occurriug on the willow at Brunswick, lie., late in August and early 
in September. 
Larva. — Body small, somewhat flattened as in Eupithecia, the surface granulated : 
the lateral ridge unusually well developed : body tapering towards each end : the 
head rather small, not so wide as the prothoracic segment; dull green, with a dull 
lilac patch near and including the eyes aud occipital region. Lateral ridge deep 
lilac, extending to both edges of the supra-anal plate : a broad, dorsal dull green 
longitudinal baud ; the setie are short and stiff, erect. Length, P2 mm . 
38. Gcomttrid larva. 
This is a common loopworm on the willow in August and early Sep- 
tember ; it rolls the leaves somewhat, hiding in the rude tent thus 
formed. It seems to have the habits of the Pyralids, aud reminds one 
of their larva^ by its well marked prothoracic shield.

wide as the body, shining, deep amber-colored ; general color dusky livid lilac and 
greenish, marbled and banded with these colors, with no definite markings: spira- 
cles black ; supra-anal plate rounded, smooth : a short, dark, shining prothoracic 
shield. Length, 20 mm . 
39. Geometrid larva. 
This caterpillar began to pupate September 2 at Brunswick, Me. 
La*-va. — Head small, rounded, not so wide as the body. Supra-anal plate moderate, 
rounded, no stripes, spots, or humps. Greenish, with a reddish tinge.

M> roptera pravella Gr. 
(Larva, PI. v: fig. 10, a, &.*) 
This is a common insect on the willow, occurring at Brunswick, Me., 
August 20, and through the month. It spins a web on the uuder side 
of the leaf, and pupates from the loth to 20th of September, the moth 
in confinement appearing (in the breeding cage at Providence) the end 
of May (the 25th-31st). The caterpillar, which is longitudinally striped 
with light and dark green, with black slashes on each side of the head, 
varies somewhat : in some there are only four slashes on the head, with 
no other markings. The moth differs from Phi/cis rubrifasciella on the 
hickory in having no cross band of raised scales, while the insect is

the plate.
