HICKORY BORERS. 293 
22. Anthaxia viridicornis (Say). 
This beetle has also been found by Mr. Harrington in abundance on 
this tree. It is a slightly larger species, he says, than the preceding, 
but closely resembles it, except that the wing-covers are of a bluish- 
black color. It is also found very commonly, he adds, on the elm. 
(See p. 229, fig. 74.) 
23. Eburia quadrigemina Say. 
This longicorn beetle has been observed by Mr. McBride commonly 
issuing from hickory trees in July. 
Thebeetle. — Body pale yellowish brown; on the thorax are two black tubercles 
above, placed transversely, with a short spine on each side. On each wing-cover 
are two double short lines of a yellow color and slightly elevated; the tip is two- 
spined, the outer spine being the longer. Length .9 inch. 
24. Heterachthes quadrimaculatus Newman. 
This longicorn was bred from hickory branches by Dr. Le Conte. 
25. Molorchus bimaculatus Say. 
This longicorn is very frequently, says Mr. Harrington, found on 
flowering shrubs during June and July, and differs from nearly all our 
Cerambycidse in having the wing-covers only half as long as the abdo- 
men. It was bred by Dr. Le Conte from hickory twigs and branches. 
The beetle. — Body slender ; black, with the head and thorax coarsely punctured ; 
the short elytra have each a yellowish dash almost parallel with the inner margin ; 
the antennae and legs are brownish. Length, one-third of an inch. 
26. Neoclytus erythrocephalus (Fabricius). 
Order Coleoptera ; family Cerambycidse. 
This beetle has been raised from hickory wood by Dr. G. H. Horn 
(Proceedings of the Entomological Society of Philadelphia, vol. 1, p.29) 
and also by Dr. Le Conte. (Amer. Ent., iii, 236.) It has also been 
found boring in a dead elm by Mr. H. G-. Hubbard, of Detroit, Mich., 
and a gravid female was found near the root of a rosebush in Washing- 
ton, D. C. (Riley.) 
27. Dorcaschema nigrum (Say). 
Order Coleoptera; family Cerambycidse. 
This longicorn bores in the hickory, according to Dr. F. Hodge, 
Buffalo, N. Y. 
28. Thysanoes fimbricornis Le Conte. 
Order Coleoptera ; family Scolytid^e. 
Mr. Harrington, of Ottawa, has "found the beetles issuing from dead 
trees in June, and they are abundant during that and the following 
month, both on dead and felled wood and on the trunks and foliage of 
living trees. 77 
The beetle. — Velvety black ; thorax cylindrical, not constricted at the head and 
but slightly behind. The wing-covers widen slightly toward the tips, which are
