ELM. TUtTHK. LEAVES. 
the first of June producing a similar beetle, differing in being destitute of 
the transverse bands branching from the lateral stripe upon the wing- 
covers, its length varying from 0.35 to 0.55. 
Two varieties of this beetle may be noticed, the one (abbreviata) having 
the stripe along the outer side of the wing-covers narrow and not extend¬ 
ing to their tips, the other (suturalis) showing a slender orange colored 
line along the inner edge of the wing-covers their whole length. 
343. Six-banded Dryobius, Dryobius, 6-fa8ciatu8 y Say. (Coleoptera. Cerombycidco.) 
A similar but larger worm than the preceding, found in the same situa 
tion, producing a black beetle of similar form, with the margins of its 
thorax yellow, and also its scutel and four equidistant oblique bands on 
its wing-covers, the last one placed on their tips, its length about 0.70. 
This species is exceedingly rare, but probably occurs in all parts of the 
Union. 
The Elm bark-beetle, $ 60, produces small pin-hole perforations in 
the bark ; and the Pigeon Tremex, which will be described under the 
Maple, bores in the wood of this tree. 
AEPECTING THE LEAVES. 
Quite a number of different worms are met with upon the elm, eating 
its leaves; but nearly all of these are oftener seen upon other trees, under 
which their description more properly belongs, and to most of them has 
already been given. A word or two as to the general appearance of these 
is all that will be required in this place. 
Of large thiclc-bodied worms, there is found on this tree 
The Polyphemus moth larva, $ 181, of an apple green color, with 
bright orange points and a row of oblique pale yellow stripes along each 
side. 
The Io emperor moth larva, $ 81, apple green, with branching 
prickles and a brick red or orange stripe along each side. 
The Ash Spinx (Sphinx quadricornis ) larva, a cylindrical green worm 
with a pale blue or green horn at the end of its back. See Ash insects. 
The American Cimbex larva, a cylindrical glaucous yellowish white 
worm, coiled like a snail’s shell and having two black lines along its back ; 
much more common on willows, under which it will be described. 
Of more slender bodied thorny worms there are 
The White-bordered butterfly larva, black, with a row of rust- 
red spots on the back, and more often met with on willows, which see. 
The Progne, $ 142, and the Wiiite-C. butterfly, $ 143, similar but 
paler colored worms. 
Of hairy-bodied caterpillars there are 
The Fall web worm, $ 81, in cobweb-like nests the latter part of 
summer. 
The Vapoiier moth larva, $ 32, with pencils of long black hairs, and 
on its back short yellow brush-like tufts.
