the tarsal formula. In form and elytral sculpture it resembles the 

 genus Liodes but the head is without antennal grooves. The terminal 

 joint of the maxillary palpi is strongly conical in Liodes also. 

 Cainosternum imbricatum new species. 



Form rather broadly oval, convex. Color piceous black, strongly shining; 

 basal joints of the antennae, legs and under side dark piceo-rufous. Head 

 rather more than one half the width of the thorax, ' sparsely but not finely 

 punctate. Head and thorax very finely micro-reticulate, reticulations rather 

 large. Thorax more than twice as wide as long, as wide at base as the elytra, 

 strongly narrowed anteriorly, sides feebly arcuate, apex rather deeply emar- 

 ginate, posterior angles obtuse but distinct, surface sparsely punctate, punctures 

 finer medially than those of the head, about as coarse externally. Elytra one 

 fourth longer than wide, widest at base, sides parallel for basal third thence 

 evenly arcuate to the apex. Sutural stria strongly impressed apically, other 

 striae barely traceable ; with eight rows of rather fine, closely placed punctures, 

 punctures finer than those on the head, intervals with irregular, incomplete 

 and sparser double series of more minute punctures, surface imbricate but not 

 at all reticulate. Imbrications very fine but sharp, difficult to find because of 

 the high lustre of the surface, equally distinct throughout. Metasternum and 

 abdomen finely alutaceous ; epipleurae strongly concave. Length 2.5 mm., width 

 1.3 mm. I specimen. 



Type 26 May. 



This species is easily recognized by the characters given. It is 

 possible that the middle tarsi may be five jointed in the male as 

 in the genus Liodes. 

 Bledius verticalis new species. 



Form somewhat robust. Color black, antennae, legs and elytra bright 

 rufous, the latter blackish basally and narrowly along the suture. Head and 

 thorax densely and finely reticulate and dull, elytra and abdomen strongly 

 shining. Head scarcely narrower than the thorax, front with a few coarse 

 punctures either side, slightly convex medially, transverse occipital groove very 

 strong, a small foveate puncture adherent to it at middle, surrounding surface 

 feebly swollen, clypeal suture distinct, entire and arcuate, antennal tubercles 

 distinct, antennae scarcely reaching the middle of the thorax, joints three to 

 six elongate, decreasing slightly in length, outer joints scarcely incrassate, as 

 long as wide. Thorax slightly wider than the base of the elytra but narrower 

 than the apex, one fourth wider than long, sides parallel and very slightly 

 arcuate in apical two thirds, strongly narrowed and subsinuate to the rounded 

 and scarcely distinct basal angles, very coarsely and rather closely punctured, 

 punctures separated by less than their own diameters, a median impunctate 

 area anteriorly ; median line fine and scarcely impressed anteriorly, coarser and 

 distinctly impressed posteriorly. Elytra one third longer than the thorax,
