88 DESCRIPTION OF INSECTS 



Far. a. Entirely testaceous. 



These I found very numerous under the bark of decaying 

 trees. 



11. B. ^proximus. Head and thorax piceous; elytra testa- 

 ceous with a blackish common disk, striae obsolete, im- 

 punctured. 



Length rather more than one-tenth of an inch. 



Head blackish piceous ; antemice rufous ; base and palpi 

 paler ; labrimi rufous. 



Thorax piceous, transversely subquadrate, slis;htly contracted 

 behind, posterior angles rectan.gular, base much broader 

 than the pedicel, basal Une slightly oblique each side, dor- 

 sal line distinct, basal ones indented. 



Elytra testaceous, a common black spot on the middle hardly 

 attaining the margin, region of the scutel dusky, strife very 

 obtuse, obsolete, wanting each side and at tip, impunc- 

 tured, interstitial lines convex. 



Pectus and postpectus piceous ; feet testaceous ; venter black- 

 ish, paler at tip. 

 Approaches the preceding, but, colour apart, it may be 



known by the thorax being more contracted behind. 



13. B. *l(eviwi piceous ', palpi whitish; elytra destitute of 

 strife. 



Length one-twentieth of an inch. 



Body piceous tinctured with rufous. 



Head rather darker ; antennw paler at base ; palpi whitish. 



T/wraa: transversely subquadrate, broadest before the middle, 

 hardly narrowed behind, lateral edge not excurved behind, 

 posterior angles slightly obtuse angular, basal edge nearly 

 rectilinear, dorsal line obsolete, basal ones wanting. 



Elytra impunctured, destitute of strife, excepting an obsolete 

 sutural one. 



Feei testaceous. 



I arrange this species with Bembidium from the habit, the 



palpi in the specimen I possess being mutilated.
