WILLOW LEAF-ROLLERS. 577 
St. Louis, Mo. The larva was uot described. The moth is at once 
distinguished from the European campoliliana Tr. by its pure silvery or 
satiny-white coloration, uutinged with yellow. Its general color is 
that of the European Boarmia roboraria Schiff, but it is much smaller 
and is very differently marked. 
The moth.— Male. Thorax olivaceous ; primaries olivaceous with a pale ochraceous 
tinge ; an oblique streak from the middle of the costa connecting with a broad some- 
what wavy stripe which extends through the middle of the wing to just before the 
apex ; two spots on inner border, one near base, the other (which is larger and more 
elongate) toward anal angle, and some costal and apical streaks brown-olivaceous; 
ocellated spot silvery, the center ochraceous, with two black stripes ; a silvery streak 
extending obliquely from the costa to the posterior margin ; fringes ochraceous* 
tinged with fuscous at apex ; secondaries gray, fuscous towards tip; fringes white, 
dusky at base ; under surface of primaries fuscous ; the fringes, except at apex, and 
some costal spots ochraceous ; secondaries gray. Expanse, 18 mm . 
46. Tortrix larva. 
This caterpillar occurred August 11 and 12, at Brunswick, Me. It 
lives between two leaves, the tent or cavity being lined by a slight 
web. 
Larva. — Head jet black with black cervical shield. Body stout, broader than the 
head and shield, gradually tapering behind. Pea-green, color of the leaves; seg- 
ments yellowish on the hind edge. Body with alternate light and dark green stripes. 
Length, 17 mm . 
47. Tortrix larva. 
This caterpillar was found feeding on the willow August 15, at 
Erunswick, Me. 
Larva. — Body thick in the middle, tapering towards each end. Head small, much 
narrower than the prothoracic segment. Body and head pale grass-green ; clypeus 
and mouth parts amber-colored. Setiferous tubercles small, inconspicuous, the hairs 
minute. Length, 15 mm . 
48. The purple willow gracilaria. 
Gracilaria purpuriella Chambers. 
Late in August (the 20th) we found the caterpillar of this beautiful 
moth, which had turned over obliquely the tip of the willow leaf and 
securely fastened it to the under side of the leaf, thus making a trian- 
gular fold. The worm had eaten the parenchyma from the under (i. e., 
inner) side, leaving a mass of black castings. The worm soon trans- 
formed, remaining about two weeks in the pupa state, and the moth 
appeared September 19. The moth is a very beautiful creature, with 
a delicate body, wings, and legs. Our example was perfect, and agreed 
in all respects with Air. Chambers' description, which is copied below. 
He did not, however, describe the caterpillar. He remarks that it is 
closely allied to the European G. stigmatella.
