 northeastern United States, since it has been recorded from Arkansas, Ken- 

 lucky, Cincinnati O., southwestern Pennsylvania, Buffalo N. Y., New Jersey 

 and the District of Columbia. 



Goes pulverulentus flald. 

 This species appears to present an interesting diversit)* of food habits 

 in various localities as illustrated by the following records. It occurs in 

 elm about Lowell Mass., as recorded by Blanchard, affects ironwood in the 

 vicinity of New York as stated by Mr Joutel, and local entomologists about 

 New York record it from beech. 



Cossonus plataiea Say 



A flattened, jet-blaik, snout beetle about ^'4 inch in length, sometimes occurs in 

 considerable numbers in butternut, poplar and other woods. 



This borer was bred in abundance from a section of butternut wood 

 cut the previous year and sent to us by Mr George .S. Graves of Newport 

 N. Y. The insects emerged in early April, and with them 

 were also obtained some specimens of Stenos cells 

 b r e v i s W^oll. 



This jet-black beetle, about '4 inch long, may be

 stout beak, and reddish antennae. The head is prolonged 

 into a .somewhat expanded beak, which latter is rather 

 coarsely punctured ; prothora.x smooth, with irregular, large 

 punctures ; wing covers deeply striate with series of rather 

 large, separate punctures. It occurs in large numbers 

 under dead butternut bark in September and October and '''', '"", ^■•^'••■""^

 numerous irregular galleries which, in the case under observation, were 

 tilled with fungus. It has been obtained by Drs Hamilton and Hopkins 

 from imder dead white walnut bark, while Dr .Smith records it from under 

 partly decayed poplar bark. This species probably inhabits the north-
