Scarlet winged clerid 



Thaneroclerus sanguineus Say 

 This brilliant little beetle occurs under the dead bark of maple and 

 beech in dry situations. It is only about 3/ l6 inch in length and has a dark 

 brown, rather coarsely punctured pubescent head and thorax and may be 

 easily recognized by the brilliant scarlet wing covers which are coarsely 

 though irregularly punctured. 



Phyllobaenus dislocatus Say 



A small, blackish, yellow-marked beetle about 3 l6 inch in length, may be met with in 

 the galleries of certain bark borers. 



This species was reared from hickory limbs obtained at Ilion N. Y., 

 the adults appearing June 20. The tree was also infested with Chryso- 

 bothris femorata Fabr., and Magdalis olyra Herbst, which 

 were preyed on by several parasites, and this clerid may possibly have 

 been subsisting- on the latter borer.

Description. The adult beetle is about 3/ l6 inch in length, the head and 

 thorax black, and the wing covers jet-black, marked with pale yellowish, 

 having an irregular oblique mark near the humeri and one 

 near the posterior third, with a small spot near the tip. The 

 head and thorax are rather coarsely punctured, and the wing 

 covers are ornamented with very coarse, almost confluent 

 punctures. This species, according to Dr Hopkins, attacks 

 Polygraph us rufipennis Kirby in black spruce, and 

 Pityophthorus consimilis Lec. in sumac, and he 

 found it associated with Scolytus rugulosus Ratz. in 

 apple. Adults were obtained by him from the middle to the * a enu S P dLi£ 

 latter part of June and in early December. Zl^n '"^^ 



Distribution. This species probably has a wide distribution in the 

 eastern United States, since it occurs in New York, and has been listed 

 from the vicinity of Cincinnati O., southwestern Pennsylvania, various 

 localities in New Jersey, and from West Virginia.
