XXVII. LoxAXDRT's Lee. l'^o2. (Gr.. "oblique + male.") 



Flattened, elongate-oblong or oval. bla.ek or piceous beetles of 

 medium or small size, possessing the ohai-aoters of the tribe Pteros- 

 tiehini. Differing from Pterostichy.s and allied genera by having 

 the front tarsi of males obliquely dilated; mandibles not striate; 

 mentum tooth emarginate. The thorax is scarcely or not at aU 

 narrowed behind and has the basal impressions single, linear and 

 straight and the front transverse line distinct, very close to the 

 apical margin. The wings are always present and there is one 

 dorsal puncture on the third interval .just behind the middle. Al- 

 though they are shining and often more or less iridescent, they are 

 rarely -with color markings rither than the piceous or yellow shades 

 of the antenna; and les-s. and, as a result, are verj- difiScult of sep- 

 aration. They live beneath stones, logs and bark, especially that 

 of oak, usually in damp locations, and when uncovered run very 

 swiftly. The followins' are the principal papers treating of the 

 genus:

About twenty species are known from the United States, six of 

 which have been taken in Indiana, while another may occur. They 

 belong to that division of the i'amily in which the side margin of 

 The thorax is not fiat'ened toward the hind angles.
