fungus and are commonly associated in a tree, not seldom occupying galler- 

 ies having a common entrance. He adds that both species are known to 

 attack wine casks and that they probably breed only in dying trees. 



Dr A. D. Hopkins has recorded this, among other species, as being 

 attracted to a freshly painted geenhouse evidently by the odor of 

 turpentine. 



Natural enemies. Only one natural enemy so far as known to the 

 writer, has been recorded. Dr .\. I). Hopkins states that he found the 

 predaceous beetle, C o 1 y d i u m 1 i n e o 1 a Say, with this species in jack oak.

Xyloterus politus Say 



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

 enters the e.xposed wood of various trees. 



This is apparently the more common species of this genus in New 

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

 fallen beechtree which had begun to decay, and also, on Aug. 23 in the 

 stump of a recently fallen soft maple at A.xton. Newly transformed pupae 

 were present in the brood chambers in the latter instance. This insect has 

 been recorded by Dr 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 E. A. Schwartz 

 has also recorded this insect as infesting ash-leaved maple and box elder, 

 N e o-u n d o ace 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
