Ephistemus apicalis Lcc. This is a viry iniiuitc. shining black spocics 

 ■\viiich occurs under beech bark in I'^ebruar)-. It is so very small that a 

 hand lens is necessary to distinguish it from mite^ found in similar places. 



Hister lecontei Mars. A small, stout, flattened, jet-black beetle occurs 

 under the dead bark of such trees as beech, maple, elm, pine etc. frequently 

 in association with various bark borers. The head is minute, partialh 

 retracted under the expanded portions of the prothora.v. The short, highl\ 

 polished wing covers are marked with several distinct striae. 



Hister parallelus .Say 



Jet-bhick, somewhat eloiii^att-d, siibcylindrii- l)ectlfs, about 'a iiicli long, may bt- met 

 witli in considerable numliers under the bark of while elm and other trees. 



This species was abundant under decaying elm bark at Albany, Nov. 

 3, 1903, and we have also met with it under spruce bark at Davis W. \'a., 

 associated with a s|jecies ol I'ityophthorus. 1 )r Hamillon rcconls the same 

 species as common under pine bark in southwestern Pennsylvania, and I)r 

 Smith finds it not rare under bark in New Jersey, and states that in one 

 instance specimens were feeding on sap. This species is not a borer, and 

 like its close relatives, is frequently found in the galleries of various wood 

 borers, where it probably feeds on partiall)' decaying or decayed vegetable 

 matter. This species has been recorded from eastern Ploritla by its 

 describer and, in addition to above named localities, has been listed by 

 Ulke from the District of Columbia and Dr Horn records it from South 

 Carolina and Georgia. 



Plegaderus transversus Say. This .stout, roundish, dark brown beetle 

 less than ' u. inch in length, occurs in early spring in damp situations imder 

 basswood hark and probably frequents other trees presenting similar 

 conditions. 



Colastus truncatus Rand. This small, oval beetle is plentiful in early 

 spring under the bark of freshl\- cut maple and butternut stumps, where it 

 feeds on the sap. It is about 3 _,, inch in length, oval, reddish brown, witii 

 the wing covers protecting onh' the anterior two thirds of the body. 



Cryptarcha concinna ^Ielsh. This species is abundant in early spring 

 under the l)ark of freshly cut maple and butternut stumps, apparently feed- 

 ing on the sap. It is a minute, oblong, banded beetle about 3/32 inch long, 

 with the thorax and wing covers obscurely marked with dark brown and 

 pale yellow.
