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. Ehuria 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- 

 splned, 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 limaculatua 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. Neoclyim erythrocephalus (Fabricius). 

 Order Coleoptera ; family Cerambycid^. 



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. (x. Hubbard, of Detroit, Mich., 

 and a gravid female was found near the root of a rosebush in Washing- 

 ton, D. C. (Riley.) 



27. Doroaachema nigrum (Say). 



Order Coleoptera; family Cerambycid^. 



This longicorn bores in the hickory, according to Dr. F. Hodge, 

 Buffalo, KY. 



28. Thysanoes fimhricornis Le Conte. 



Order Coleoptera ; family Scolytidje. 



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." 



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
