trunks of hickory trees, the worm often working its way out of 

 the wood after it has been made into articles of furniture or 



carriages. The ^l.sv-

 111:111 (Fig. 4<s3 ; a, <i, 

 larva ; 1>, pupa), we 

 have found in all its 

 stages under the bark 

 of oaks, early in May. 

 The larva is footless, 

 white ; the head is 

 rather large, whit e , 

 with strong black jaws 

 convex on the outer side ; the body is uniform, gradually 

 diminishing in width posteriorly ; it is .(!() of an inch long. 

 The pupa is .44 of an inch long. The beetle is about half an 

 inch long and is dark brown, with very thick femora. 

 It flies the last of May. I have received a larva of this 

 species from Dr. Shinier, which was found by him boring

 of moderate length, a broad rounded pro thorax, and a flattened 

 body behind. The larvae are unusually flattened, with a broad

 reddish brown, with a white

 black spot. It was discovered in Pennsylvania. 



Clytiis has a more cylindrical body, and spherical prothorax. 

 besides being beautifully banded with golden, on a dark 

 ground. Clytus spwiomm Say injures the maple. AVe have 

 taken the beetle on the summit of Mount Katahdin in Maine. 

 The beetle lays its eggs in July and August, and the larvtv
