Xyloterus politus .Say 



A small light brown to nearly black, cylindric beetle, about '8 inch long, frequently 

 enters the exposed wood of various trees. 



This is apparently the more coinmon species of this genus in Nev 

 York .State. It was taken by the writer at I*"loodwood, Aug. 21, 1900, in a 

 fallen beechtree which had begun to decay, and also on Aug. 2_^ in th^ 

 stump of a recently fallen soft maple at .V.xton. Xewly transformed pupae 

 were ])resent in the brood chambers in the lattir instance. This insect has 

 been recorded by l)r Hopkins as occurring in the following trees: beech, 

 black oak, white oak, red oak, hemlock, sugar maple, red maple, chestnut, 

 mao-nolia, elm, hickory, ash, birch and black spruce. Mr V.. A. Schwartz 

 has also recorded this insect as infesting ash-leaved maple and bo.x elder, 

 N egu n do ac e r o i d e s. It will be seen by the above that this species is 

 not closely limited in its selection of trees, and it appears ver' probable 

 that the condition of the trunk has much to do with its being attacked. 



This borer is stated by Mr Hubbard to infest the sapwood of deciduous
