ALDER INSECTS. 635 
25. Calligrapha scalaris Le Conte. 
This beetle is a common frequenter of alders, feeding on the leaves, 
in Maine, through the summer in both the larval and beetle states. 
Whether the subjoined description applies to this species or not we do 
not feel sure. It occurred on the alder September 3. 
Larva. — Body long, flattened, the prothoracic segment nearly as broad as the mid- 
dle segments of the body. Head reddish, about one-half as wide as the prothoracic 
segment. Body whitish-green, along the back a row of transverse black spots, two 
to each segment, and oval-lanceolate in shape ; those on the prothoracic segment much 
larger than the others, together forming a patch longer thau broad. On the meso 
and meta segments is a lateral narrow sublunate black mark. Spiracles black. Length 
6 mm to 8 mm . 
26. Chlamy8 plicata Oliv. 
This singular little beetle was observed on the leaves of the alder, in 
Maine, September 19. The larva and its case have been figured in my 
Guide to the study of Insects, p. 510. 
The beetle. — Body obscure, bronzed. Head impressed posteriorly between the eyes, 
rhinarium, antennae, and an elevated space adjoining the eyes anteriorly, rufous; 
nose distinctly punctured; prothorax very finely and concentrically scored, with 
some scattered indistinct punctures ; posteriori \ considerably elevated ; elevation 
bifid ; behind this elevation the prothorax is producted and emarginate ; scutellum 
obtriangular ; elytra tuberculated with several acute, compressed tubercles, the an- 
terior ones carinated; interstices with some scattered deep punctures ; space between 
the four posterior legs punctured with large shallow punctures. Length of body 2 
lines. (Kirby.) 
27. Gelechia coryliella Chambers. 
Whether the larva which we describe below is the same or congene- 
ric with that of Pcedisca transmissana, said by Mrs. Dimmock to be 
common about Cambridge, Mass., eating the inside of the sterile 
catkins of the white birch, and hibernating 
as a pupa — we do not know. The worm in 
question occurs at Providence through Oc- 
tober (and we have found belated individ- 
uals as late as November 10) eating the in- 
terior of the catkins of both the alder and 
the hazel. It devours the interior some- 
times at the base and sometimes at the 
apex; it sews together two or three cat- 
kins, throwing out a mass of castings 
which remain in the web. November 10 a 
larva left the catkin and spun a cocoon 
lined with silk, and covered on the outside 
™™ withbitsofcatkiDS . The larva appeared 
to me to be, from its shape and general ap-

the middle of the central catkin.
