630 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
16. The alder leaf-roller. 
(iihchia oronella Walsingham. 
Order Lepidopteka ; family Tixeid.l. 
While the leaves of the alder are variously folded and rolled by 
caterpillars, perhaps the most striking leaf-roller is the above species, 
which occurred in Maine late in the summer, in August and the early 
part of September. 
The little worm is amber-colored, the body rather thick and cylindri- 
cal, but with no distinctive markings. One was observed which had 
sewed a portion of the edge of the leaf for half an inch in extent with 
four or five large white silk stitches. The moth, which appeared in the 
breeding cage May 4 of the following year, is described below. ■ 
In another example, probably of this species, the end of the leaf was 
rolled up one and a half turns, and sewed with three broad strong silk 
stitches. On unrolling it the end of the leaf was fouud to be more or 
less eaten, the roll being gradually drawn in and made more perfect as 
the caterpillar consumes the tip of the leaf. It pupated September 18. 
I am indebted to Professor Fernald for the identification of this 
species. 
Larva. — Body rather thick, cylindrical; body and head delicate ainber-colored ; 
end of the body with quite long hairs, longer than the body is wide. Length, 6 mm . 
Pupa. — Rather thick ; mahogany-brown ; length, 7 mm . 
Moth. — Palpi with the second joint moderately broad, scarcely more than twice as 
wide as the third joint, which is moderately broad and two-thirds as long as the sec- 
ond joint. Head and palpi whitish-gray ; second joint black externally ; third joint 
white with two black rings. Fore wings of the usual shape; white-gray; at the 
base a black streak parallel to the costa ; on the basal fourth of the wing is a pair 
of converging black spots; beyond is a similar but thicker pair of black spots, and 
still beyond another pair, one of the spots being situated on the costa ; four black 
costal spots towards the apex of the wing. Hind wings pale glistening gray. Ex- 
panse of wings, 18 mm . 
17. Tineid larva. 
This larva was observed feeding between the leaves of the alder dur- 
ing the first two weeks of August (August 1 to 13), at Brunswick, Me. 
Larva. — Body slender, tapering towards each end ; head pale whitish amber; con- 
siderably narrower than the prothoracic segment. On the last segment from four to 
six long dark hairs. Color, pale grass-green. Length, 7 m,n . 
18. The alder flea-beetle. 
Haltica alni Harris {H. bimarginata Say). 
In the correspondence of the late Dr. Harris the following mention is 
made of this beetle : 
In traveling from Center Harbor, N. H., to Conway, on the 2d of August, 1854, 
and from Conway to Upper Bartlett, and subsequently to Jackson, we saw the alders 
(Alnus serrulata) everywhere ravaged by insects which had destroyed their leaves in
