60 INSECTS INJURIOUS TO FOREST AND SHADE TREES. 
6. THE SHORT-LINED DULARIUS. 
Dularius brevilineus Say. 
Order COLEOPTERA; family CERAMBYCID®. 
Boring in partly dead or dry elms, the larva of a pretty longicorn, with deep pur- 
plish-blue wing-covers with three short white lines in the middle. 
This beetle was first bred from the dry wood 6f the elm by Riley, 
the larve occurring in Ohio. It was also known, by the late Mr. G. D. 
Smith, to inhabit this tree, probably in the vicinity of Boston; it was 
noticed in our 2d Mass. Report, 
p. 18. Mr. George Hunt has ob- 
served this beetle on the bark of 
an elm at Plymouth, N. H., in 
the middle of July, inserting its 
eggs in the crevices of the bark. 
It is a singular-looking beetle, 
with a round, flattened protho- 
rax, and wing-covers contracted 
in the middle, and not covering 
the tip of the abdomen, while 
the thighs are unusually swollen. 
The antenne are about two- 
thirds the length of the body, 
flattened towards the end, and 
somewhat serrate. The body 
above is velvety black, and brown-black beneath. The head is black 
and coarsely punctured, and the prothorax is covered with short, dense, 
black hairs, like velvet. The wing-covers are Prussian blue in color, 
bent, corrugated, with an interrupted ridge just outside of the middle of 
each cover. They are covered with fine, black hairs, bent over. There 
is a pair of parallel, short honey-yellow lines in the middle of each 
wing-cover, with a third one a little in front, making in all six streaks. 
The legs and feet are black. It is a little over eight-tenths of an inch 
in length.

6. Neoclytus erythrocephalus Fabricius. 
Order COLEOPTERA; family CERAMBYCID. 
Boring in dead elms in Michigan (Hubbard); also raised from hickory-wood (Horn). 
7. THE TREE CRICKET. 
(Ecanthus niveus Serville. 
Order ORTHOPTERA; family GRYLLID®. 
Boring into the corky bark of the elm in the Southern States, inserting its eggs 
irregularly, not in regular series as when it oviposits in the stems of the blackberry, 
raspberry, grape, &c.; a slender pale-green cricket, with white wings and a large 
ovipositor; the males shrilling loudly.
