about two-thirds wider than long, the sides in general form nearly straight and 

 strongly convergent from base to apex, continuing the sides of the elytra ; punc- 

 tures fine but deep and not very close-set, the surface shining ; submarginal line 

 rather feeble; elytra oval, before the middle much wider than the prothorax, 

 scarcely three times as long as the latter, the punctures fine and sparse, the double 

 series ill-defined. Length 1.6 mm.; width 0.78 mm. New York. 



obesulus, sp. now 

 Body throughout in form and coloration as in ol>esti/ns, but a little stouter, the pro- 

 thorax nearly four-fifths wider than long, with the sides feebly convergent, nearly 

 straight in general form but not continuing the sides of the elytra, the surface less 

 finely, very deeply and very closely punctate, the submarginal line parallel to the 

 edge fine but strong ; elytra nearly as in obesnli/s but more broadly oval and with 

 more prominent humeral callus, the punctures larger and less sparse, the pubes- 

 cence longer, more abundant and with very long erect subserial hairs in addi- 

 tion. Length 1.7 mm.; width 0.85 mm. Iowa (Iowa City) — Mr. Wickham, 



hirtus, sp. nov. 



These species are mutually verv closely allied but appear to be dis- 

 tinct. The genus is probably confined to the Atlantic regions of the 

 continent. 



Salebius, gen. nov. 



This genus, with Crosimus, is distinguished from Cryptophagus by 

 having three subequal obtusely dentiform nodal points along each side 

 of the prothorax —at the apex and near apical and basal fourth of the 

 length, instead of a single nodal point, with a submedian spicule as 

 in that genus. The node at the apical angles in Salebius is merely 

 thickened, convex and more or less pubescent, but the two posterior 

 often have a deep puncture at the middle of the summit analogous to 

 the central puncture of the flattened apical node so prevalent in Cryp- 

 tophagus. The tarsi are long and slender and nearly all the other 

 anatomical structures are similar to those of Cryptophagus, except that 

 only the anterior two of the pronotal callous spots are visible, and the 

 impression along the basal margin is feebler, with the median carina 

 always distinct. The five species in my cabinet may be recognized 

 as follows : — 



Punctures very fine but deep as usual, those of the pronotum very dense ; body dark 

 piceous, blackish beneath, the antennae and legs castaneous ; pubescence short, 

 even, decumbent and rather abundant, more distinct on the pronotum along the 

 sides and median line ; prothorax parallel and slightly rounded at the sides, not 

 more than one-half wider than long; elytra two-thirds longer than wide, only 

 slightly wider than the prothorax and fully three times as long, the punctures fine 

 and rather close-set; hind tarsi nearly as long as the tibia; ( 9 )• Length 2.4 

 mm.; width 0.9 mm. Queen Charlotte Islands (Massett) — Mr. Keen.
