286 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



This is perhaps the most common borer in the hickory and walnut 



in the Northern States. According to Fitch 

 the young worm lives at first upon the soft 

 outer layers of the sap-wood, mining a shal- 

 low cavity all around the orifice in the bark, 

 and the bark dies and turns black as far as 

 this burrow extends. Its jaws having at 

 length become sufficiently strong, it gnaws 

 its way into the solid wood from the upper 

 part of its burrow under the bark, boring 

 obliquely inward and upward, all the lower 

 part of its burrow being commonly packed 

 with its sawdust-like chips. Finally, hav- 

 ing completed its growth, it extends the up- 

 per end of its burrow outward again to the

2. The beautiful hickory borer. 

 Goes pulchra (Haldeman;. 



Similar to the preceding. " Scarce, but a few are found every season 

 in the shagbark and T)ignut hickory, June 

 and July." (Dr. T. Hadge, Buffalo, K Y., 

 Amer. Ent. iii, p. 270.) 



3. Goes oculatus Lee. 



Another but much smaller species is Goes 

 oculatus Lee. "The beetle is rare, and I 

 have only taken two specimens. There were 

 a pair captured on hickory 

 in the end of June, and 

 which were copulating when 

 taken. They are hardly 

 half an inch long, and are 

 black, densely covered be- 

 neath with short white hairs. The pubescence above 

 is more sparse and scattered, and the coarse punctur- 

 ing of the elytra gives them a mottled appearance. 

 There is a black spot on each elytron just behind the 

 middle, and the presence of these spots gives to the 

 beetle its distinctive name of ^'•oculatus or eyed." 

 (W. H. Harrington, Eep. Ent. Soc. Ontario for 1883, 



p. 48.) 



4. Goes debilis Lee. 



Fio. 109 —Goes pulchra (Smith del).

 (Smith del). 



Like the foregoing species of Goes, this is known to inhabit hickory 

 trees, but its larva has not been yet identified with certainty, and its 

 habits need to be studied.
