Hermit flower beetle. Osmoderma eremicola Knoch. This 

 flower beetle is slightly larger than the preceding, of a dark mahogany 

 color, with smooth, highly polished wing covers. It presumably has the 

 same habits as the preceding form. 



Stenosphenus notatus Oliv. This insect was taken at Poughkeepsie on 

 dead hickory and oak. It has been recorded as breeding in dead limbs of 

 the former. 



Lepturges symmetricus Hald. This species was taken in early July on 

 beech injured by fire. 



Oberea schaumii Lec. This species bores in the twigs and branches of 

 poplar, beetles appearing in early May. 



Oberea ocellata Hald. This small longicorn has been reared from 

 sumac. 



Scotobates calcaratus Fabr. This large, black beetle about inch in 

 length, occurs under the dead bark of various hard woods. The head and 

 thorax are rather finely, irregularly punctured and the wing covers marked 

 with conspicuous striae composed of fine and in many cases confluent 

 punctures. 



Tenebrio tenebrioides Beauv. This large, brownish black species occurs 

 under decaying willow, butternut and basswood bark in early spring. It is 

 about y 2 inch long, rather stout, the head and thorax are finely and irregu- 

 larly punctured, while the wing covers are ornamented by series of striae 

 composed of thickly set though distinct punctures. 



Penthe obliquata Fabr. This species is very similar to the preceding 

 and like it, occurs under dead beech bark, particularly on trees that are 

 down, and may be distinguished from the following by the yellowish 

 scutellum and from the preceding by the deeply impressed thorax and the 

 coarsely punctured elytra. It is also a somewhat stouter form. 



Penthe pimelia Fabr. This stout, black species occurs under dead 

 beech bark, most frequently on trees that are down. The head and thorax 

 are coarsely punctured, the latter with a deeply impressed spot posteriorly. 

 The wing covers are coarsely marked with irregular series of deep 

 punctures. 



Melandrya striata Say. This large, black beetle occurs under the dead 

 bark of beech, maple and probably of other trees in July. The beetles 

 range in length from 7/ l6 to about 5/g inch and may be recognized by the 

 very finely punctured head and thorax, the latter tapering strongly ante- 

 riorly, and specially by the prominently ridged, slightly pubescent, finely 

 punctured wing covers. 



Phloeotrya liturata Lec. This black or dark brown, yellow-marked 

 melandryid is about 5/ l6 inch long and occurs under dead maple bark the 

 latter part of June and July. It may be recognized by the rather peculiar 

 irregular black mark on each side of the anterior third of the elytra
