works in decaying birch and it is probable that the larvae are somewhat 

 similar [see p. 466, fig. 116 for an illustration of this latter insect]. 



Grynocharis quadri-lineatus Melsh. 



This black, rather flattened beetle occurs on beech stumps in May. 

 The eyes are medium, rather finely granulated ; head somewhat coarsely, 

 and prothorax rather finely punctured, while the wing covers are marked by 

 a number of conspicuous ridges with the interspaces coarsely punctured, 

 almost reticulate. 



Xylocleptes species 



Dark brown or black beetles, about '/ 32 inch long, make longitudinal burrows in 

 partly decayed sugar maple limbs. 



This species was met with by the writer in very small numbers August, 



1901 at Axton N. Y., in a dead sugar maple limb. The adult beetles run a 



somewhat tortuous longitudinal gallery just under the 



bark and escape, as in the case of most bark borers, 



through round holes about 1 ,, 4 inch in diameter. A 



central chamber was detected in one instance and in this 



case there were two longitudinal galleries proceeding 



therefrom and slight notches indicated the beginning of 



two others. Eggs are evidently deposited on either side 



of the burrow and the young makes somewhat tortuous 



galleries at approximately right angles to those of the adults. The insects 



were probably breed- | 



ing at the time they « 



were collected, as a Fig. 113 X y 1 oc 1 e p te s work in decaying maple twig (original) 



few larvae were seen but not preserved. 



Description. The beetle is less than 3 32 inch in length, cylindric, rather 

 slender and of a dark brown color except the legs, which are a light brown. 

 The head is well retracted and the black eyes are coarsely granulate. The 

 anterior portion of the prothorax is tuberculate, the dorsal part and the 

 wing covers or elvtra are rather sparsely and coarsely punctured.
