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 iuch. 



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. Agrilus egenus Gory. 



Stated by Dr. Le Conte to live in the trunks and branches of Gary a 

 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 ^'S- in.— Acanthoderes 

 baud of white in front of the middle. (Harrington.) 4.flri66u».-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.
