quite close-set ; elytra oblong, feebly arcuate at the sides, obtusely rounded at 

 apex, barely three times as long as the prothorax and about a fourth wider, the 

 punctures very fine and moderately close-set. Length 1.5 mm. ; width 0.75 mm. 

 Colorado oblongula, sp. nov. 



Body deep black throughout, the legs and antenna; piceo-testaceous ; surface polished, 

 the pubescence short and inconspicuous ; antenna; moderately slender, distinctly 

 longer than the head and prothorax, the latter convex, two-thirds wider than 

 long and fully as wide as the base of the elytra, dilated and strongly rounded 

 laterally just before the middle, the converging sides thence nearly straight to 

 the base and apex, the latter but little narrower than the base, the basal impres- 

 sion moderate, extending throughout the width but feeble at the sides, the punc- 

 tures fine but deep and strong and not very close-set ; elytra short, oblong, two 

 and one-half times as long as the prothorax and barely a fifth wider, parallel and 

 broadly arcuate at the sides and obtusely rounded at apex, rather strongly and 

 moderately closely impresso-punctate. Length 1.3 mm.; width 0.6 mm. Iowa. 



crypta, sp. nov. 



Body very small, parallel, pale testaceous, the elytra gradually shaded blackish to- 

 ward base ; integuments shining ; antenna; slender, nearly half as long as the body ; 

 prothorax short and strongly transverse, about as wide as the elytra, angulato- 

 dilated at the middle, the apex distinctly narrower than the base ; punctures 

 minute and moderately dense, the basal impression rather acutely impressed ; 

 elytra parallel, feebly arcuate at the sides, obtusely rounded at tip, three times as 

 long as the prothorax in the female but obviously shorter in the male, the punc- 

 tures very fine and moderately close-set. Length 0.88-I.05 mm. ; width 0.35- 

 0.48 mm. Europe and Northeastern America pusilla Schonk. 



18 — Body oblong-suboval, parallel, convex, polished, blackish in color, the elytra grad- 

 ually pale posteriorly and the humeral callus also slightly paler ; legs and antenna; 

 testaceous ; the latter moderately slender, nearly half as long as the body, the 

 club rather thick ; prothorax moderately transverse, rounded on the sides, more 

 strongly toward base, from above, but broadly subangulate at the middle when 

 viewed sublaterally, the punctures fine and moderately close-set, the ape 4 but 

 little narrower than the base, the basal impression distinct ; elytra parallel, 

 broadly arcuate at the sides, but little wider at the middle than at base and only 

 slightly wider than the prothorax, nearly three times as long as the latter, moder- 

 ately obtuse at tip, the humeri evidently exposed at base ; punctures fine but 

 strong and distinct, scarcely sparser than those of the prothorax. Length 1.2 

 mm.; width 0.5 mm. California fallax, sp. nov. 



19 — Species of the Atlantic regions. Body oval, rapidily attenuate at the extremities 

 and very convex, shining, black or piceous-black, the legs and antenna; testace- 

 ous, the latter notably stout, nearly half as long as the body in the male ; pro- 

 thorax small, less transverse than usual, three- fifths wider than long, the sides 

 strongly converging anteriorly, the apex only two-thirds as wide as the base, the 

 latter with a feeble but distinct arcuate lobe in median third ; punctures rather 

 strong and close-set, the impression somewhat feeble ; elytra oval, subinflated, 

 and, at two-fifths, very much wider than at base and a third wider than the pro- 

 thorax, the base of the latter scarcely at all narrower than the base of the elytra, 

 the humeri not exposed at base ; apex narrowly rounded, the punctures fine but
