HICKORY BORERS. 291 
any apparatus which can serve as such, except two small warts on the under side of 
the second segment from the thorax. (Harris.) 
The beetle. — Of a lurid or dull brassy color above, bright copper beneath, and thickly 
punctured all over ; there are numerous irregular impressed lines, and several nar- 
row elevated black spots on the wing- covers, the tips of each of which end with two 
little points. Length 0.60-0.80 inch. 
12. The slender- footed dysphaga. 
Dysphaga tenuipes (Haldeman). 
A small grub, in the dead limbs and twigs, producing in May a small black longi- 
corn beetle with rough wing-covers but half as long as the abdomen and tinged with 
paler yellowish at their bases, its head having a furrow in the middle and its thorax 
cylindrical. Length 0.25 inch. (Fitch). 
13. Chrysobothris femorata Lee. 
This Buprestid has been found by Mr. W. H. Harrington "very 
abundantly on dead hickories from June to September, and the fact 
that the larvae live upon this tree was established by finding a beetle 
in its burrow under the bark. (Rep. Ent. Soc. Ontario for 1883, 44.) 
14. Agrilu8 egenus Gory. 
Stated by Dr. Le Gonte to live in the trunks and branches of Carya 
tomentosa. 
15. Agrilus sp. 
This species, said by Le Conte to be "probably new," he has bred from 
the branches of Carya tomentosa, 
16. Acanthoderes quadrigibbus (Say). 
While Dr. Le Conte bred this longicorn beetle 
from branches and twigs of hickory, Mr. Schwarz 
has found it boring in the dead twigs of the oak, 
beech, and hackberry. 
The beetle. — It is broader and flatter than the species of 
Goes; the prothorax in addition to two lateral spines has 
two more above, whence the name quadrigibbus or 4-horned. 
The legs are nearly of a uniform length, and the thighs are 
much enlarged. The general color is a mottled gray, due 
to pubescence, and there is a moderately broad transverse Fi S- U7.— Acanthoderes 
band of white in front of the middle. (Harrington. ) i- gibbus. -Smith del. 
17. Liopus cinereus LeCoute. 
This longicorn has been bred from hickory twigs by Dr. LeConte. 
It is allied to the L. alpha Say, which bores in dead apple twigs, the 
beetle occurring in July. L. cinereus is closely similar to L. alpha, but 
differs in the coarser punctures of the wing-covers. The latter species 
is also thought by Mr. Harrington to live at the expense of the hickory.
