apex is therefore never deeply angularly incised, as would be the 

 case when the two edges are oblique, as in Bledius. 



In the table and descriptions given below, the specific characters 

 throughout are drawn from the male only. 



The species belonging to our fauna, although as far as known 

 only five in number, are easily divisible into two distinct groups as 

 follows : — 



Anterior coxal cavities extremely large, angulate, extending to within a short 

 distance of the lateral edges of the prothorax, this distance being not 

 greater than the distance separating them from the anterior margin of 



the prosternum I 



Head and prothorax narrower than the elytra; eyes moderate, the tempora 



behind them equally prominent and but slightly longer linearis 



Head and prothorax as wide as the elytra ; form parallel ; eyes very small, 

 the tempora behind them nearly three times as long, strongly arcuate and 



much more prominent ceplialotes 



Anterior coxal cavities smaller and shorter, broadly triangular, the hypomera 

 wide, the distance separating the cavities from the lateral margin of the 

 prothorax much greater than their distance from the anterior margin of 



the prosternum 1| 



Head equal in width to the prothorax or extremely nearly so ; basal joint 

 of the antennse subeqaal in length to the next three together ; elytra 

 distinctly less than twice as long as the prothorax. 

 Antennse much longer than the head and prothorax together ; sides of the 



abdomen straight and feebly divergent from base to apex pi'iiiceps 



Antennfe about equal in length to the head and prothorax, the joints more 

 compactly joined and more transverse; sides of the abdomen parallel 



and evenly, distinctly arcuate throughout flaTipeiinis 



Head slightly, although distinctly, narrower than the prothorax ; basal joint 

 of the antennje shorter, subequal in length to the next two together ; 

 elytra about twice as long as the prothorax.; sides of the abdomen ]»arallel 

 and straight , aiinecteilS 



A. linearis Lee. — Haplodcms Un. Lee, Smith. 8vo., n. sp. Col., p. 54. — 

 Slender, black ; elytra and sometimes prothorax paler, dark piceous-brown ; 

 polished ; pubescence very sliort, extremely sparse. Head equal in width to 

 the prothorax ; eyes moderate, nearly equal in length to, and rather more 

 convex than the tempora behind them, the latter as prominent as the eye ; 

 antennse rather slender, geniculate, the basal joint as long as the next three, 

 second scarcely visibly longer than the third, oval, the latter strongly obconi- 

 cal, tenth joint very slightly wider than long. Prothorax nearly three-fourths 

 wider than long ; sides strongly arcuate anteriorly, feebly convergent and 

 straight toward base, the base and apex broadly arcuate ; basal angles 

 rounded ; disk very sparsely, deeply punctate, with a broad median iinpunc- 

 tate line, on either side of which there is a narrow, feeble and rather indefinite
