prothorax being- tubularly narrowed behind the middle antl with a rugose 

 disk. The elytral punctures are deep, not very large or crowded, and the 

 under surface is clothed with a pale pubescence, giving a leaden effect. This 

 insect appears to be confined to the hickory, from which it has been bred 

 by a number of entomologists. It has been recorded by Messrs Leng and 

 Hamilton from New York, Massachusetts, Canada West, northern Illinois, 

 Louisiana, has been bred from hickory in southwestern Pennsylvania by 

 Dr Hamilton, found flying in a spruce forest in West Virginia by Dr Hop- 

 kins, and listed by others from the vicinity of Buffalo N. Y., Cincinnati O., 

 and the District of Columbia. Dr Smith records it from a number of 

 localities in New Jersey. 



Red-edged saperda 

 Sapcrda lafcralis Fabr. 

 A brownish black, red^-bordered beetle about ] '2 inch long, bores as a larva in 

 hickory. 



This species is rather rare and exhibits a marked preference for injured 

 portions of hickories near the root and the base of sprouts on recently 

 cleared land. The larvae frequently work along the juncture of dead and 

 living bark and inhabit the base of dead shoots. 

 This species has been recorded from alder, though 

 this appears to be an exceptional food plant. 



Euderces picipes Fabr. 



A small, jet-black beetle % inch long, and with an 

 oblique white line on each side, works in hickory and chest- 

 nut branches. 



This small beetle presents a somewhat general 

 resemblance to an ant because of the snowy white, 

 oblique stripes on either side near the middle of 

 the wing covers. The prothorax is strongly con- 

 stricted behind and inclosing most of the head, assists in this deception. 

 The antennae are about as long as the body and the femora strongly 

 swollen. This little species is not abundant enough to cause material
