A small, characteristic species, easily identified by strongly prom- 

 inent mandibles, also by the characters of pronotum and elytra. 



Black, feebly greasy glistening; head, pronotum, and abdomen with spar- 

 se and rather long, but elytra with dense and very short, whitish hair- 

 ve6titure; elytra straw-colored, at base and suture more or less widely 

 black, occasionally almost entirely black; the antennal intermediate joints, 

 mandibles, tibiae and tarsi rust-colored. 



Body (Fig. 156) is of equal breadth; head much smaller than pronotum, 

 both with rather fine and isolated punctation, the surface distinctly sha- 

 greened, mandibles strongly promonent, antennae short and robust, and with 

 three-jointed set-off club; pronotum hardly narrower than elytra, almost 

 twice as broad as long, with posteriorly strongly oblique and suddenly 

 constricted sides, and with sharp, almost rectangylar hind corners, rather 

 convex, finely, but sharply middle-grooved; elytra proportionally long, 

 almost twice a? long as pronotum, finely and densely punctated; abdomen 

 of equal breadth, sparsely punctated; hind tibiae in outer margin with 

 4-E rather robust spines. L. 3-3.5 mm. 



In the O the mandibles are somewhat more prominent than in the Q 

 and inside of the thinned out grasping-part armed with a more=robust 

 t00th (Fig. 156. Bledius arenarlus Favk.) -
