Chariessa pilosa Forst. 

 This rather stout, black beetle with yellow-margined prothorax, may be easily 

 recognized by reference to the accompanying figure. 



This clerid, about ]/ 2 inch long, is predaceous and 

 undoubtedly renders considerable service in keeping 

 various pests in check. Specimens were taken at Pough- 

 keepsie on a hickory tree in which Dicerca lurida 

 Fabr. was ovipositing, and Dr Smith records its occur- 

 rence in New Jersey on oaks and also pear infested 

 by the sinuate borer, Agrilus sinuatus Oliv., 

 the larva probably preying on the pupa of this latter 

 insect. Dr Hopkins states that the larvae are very 

 efficient checks on several of our destructive flat-headed 

 buprestid borers.

This very dark brown beetle about y% inch long, occurs in the gal- 

 leries of Scolytus quadrispinosus Say, and has been recorded 

 in those of Xyleborus celsus Eich., preying undoubtedly on this 

 ambrosia beetle. It has been recorded from the vicinity of Washington, 

 West Virginia and New Jersey, and is probably widely distributed in the 

 northeastern United States. The antennae are reddish, stout, moniliform, 

 the terminal segments being larger than the basal ones. The eyes are 

 prominent, black, coarsely granulate ; the head and prothorax brown, 

 irregularly and finely punctured, the latter being remarkable because of the 

 prominent median sulcation. The wing covers are very dark brown or 

 black, sparsely clothed with rather coarse hairs and irregularly and finely 

 punctured.
