occurs in early spring under dead elm bark. It is about Y / 2 inch long with 

 conspicuous blackish moniliform antennae, the head and thorax are strongly 

 flattened, irregularly and coarsely punctured, the latter with a series of 

 minute denticulations along its lateral margins ; wing covers finely punc- 

 tured and apparently hollowed. The humeral angles are continued as 

 conspicuous ridges along their entire length. 



Laemophloeus biguttatus Say. This small, flattened beetle may be 

 found under dead maple bark in April and May. It is about ]/% inch long, 

 the head and thorax are finely though irregularly punctured, mostly dark 

 brown, while the wing covers are finely striate with series of confluent punc- 

 tures and are mostly dark brown with a middle, somewhat broken band of 

 pale yellowish 



Laemophloeus testaceus Fabr. This minute, slender, flattened beetle is 

 not uncommon under the dead bark of maple and beech stumps in early 

 spring. It is about 3 32 inch long, the slender antennae are nearly as long 

 as the body. The brown head and thorax are rather finely and sparsely 

 punctured, the latter with distinct sublateral ridges and with the lateral mar- 

 gins prolonged, toothed posteriorly ; wing covers finely striate with series 

 of minute punctures ; lateral margins produced. 



Dendrophagus cygnaei Mann. This flattened, brownish species occurs 

 under elm bark in March and April. The dark brown head and thorax are 

 ornamented with irregular, coarse punctures and the brown wing covers are 

 striated with series of rather large, almost confluent punctures ; humeral 

 angle pronounced and continued as a distinct ridge along the entire length 

 of the wing covers. The legs are light brown with strongly swollen femora. 



Uliota dubius Fabr. This flattened, 

 brownish or black beetle occurs under 

 dead elm, beech, maple and butternut 

 bark in early spring. It is about inch 

 long, dark brown or blackish. The red- 

 dish brown antennae are as long as the 

 body, and just anteriorly there is on each 

 side a conspicuous curved, hornlike pro- 

 cess apparently peculiar to the male. 

 The dark brown head is coarsely punc- 

 tured with two deeply impressed lines ; 

 the prothorax is also coarsely punctured, 

 with lateral margins serrate, the anterior 

 angles being prolonged into conspicuous 

 processes. The wing covers are coarsely

striate with a conspicuous humeral ridge 

 their entire length and the interspaces ornamented with numerous con- 

 fluent coarse punctures.
