The beetle is intermediate in size between the two chestnut 

 weevils. The beak is long and prominent but is a trifle shorter 

 than in either of the species that attack chestnuts. The color of 

 the beetle is dull, dark brown with a grayish tinge in fresh speci- 

 mens due to a sparce covering of whitish, scale-like hairs. The 

 larva is yellow with a red head and is similar in shape to those 

 of the other species. 



The beetles appear on the trees in July, my earliest record 

 being for July 29th, 1908, when eleven were caught on the low- 

 er branches of a pignut hickory. On August 8th, 1906, I found 

 the punctures of the weevils quite abundant in the husks of 

 hickorynuts but these punctures were shallow and had evidently 

 been made for feeding as they contained no eggs. My first ob- 

 servation of oviposition was on August 23rd, 1906, when a fe- 

 male was seen to deposit an egg in a nut of the white-heart 

 hickory. 



Oviposition has been observed on August 23rd, 25th, 27th, 

 30th and September 14th and 24th. Evidently, in this locality, 

 most of the eggs are produced from August 25th to September 

 25th. At the time of oviposition the nuts are approaching ma- 

 turity, and, as the eggs are placed within the meat of the nut, it 

 is necessary for the beetle to make an 

 opening through the husk and shell for 

 the insertion of the egg. This it does, 

 after the manner of its kind, by drilling 

 a hole with its snout to the desired depth 

 in the nut. 



Other nut weevils in depositing their 

 eggs have to contend with the spines of 

 the chestnut bur, the glutinous involucres 

 and hard shells of the hazelnat and the 

 woody cups of acorns but this species has the greatest obstacle 

 of all to overcome in the form of the thick, horny shell of some 

 of its favorite varieties of hickorynut. Its manner of accom- 

 plishing the task is interesting and may be explained best by de- 

 scribing the operation as it was observed on September 14th
