by its narrower form and decidedl}' shorter elytra ; the first two 

 joints of the antennae bear long black apical setge as in debilis, 

 but the tip of the abdomen is paler and more acute in subtilis.

Rather narrowl}^ suboval, convex, shining, castaneous, the an- 

 tennae somewhat short and incrassate, with the penultimate joint 

 transverse. Prothorax one-half wider than long, the sides arcu- 

 ate, l)ecoming parallel toward base, the basal angles obliquely and 

 moderatelj' prominent posteriorly and only slightl}' blunt ; disk 

 ver}' coarsel}' but feebl}- reticulate. Elytra short, nearly one-half 

 wider than long, narrowed behind, distinctly shorter than the 

 prothorax, with the external angles at apex but little rounded and 

 the disk very coarsely imbricate. Abdomen rapidlj'^ tapering, the 

 long black set^e apparently obsolete toward base. Length 1.15 

 mm.; width 0.7 mm. 



North Carolina. This is the smallest species of the genus, and 

 is very distinct from the two preceding in its coarse imbricate 

 sculpture and A^ery short elytra. The epipleurae are narrow, entire, 

 becoming gradually and moderately deepl)^ vertical externally to- 

 ward base, and are slightly pubescent posteriorly. The male has 

 a large triangular emargination at the apex of the sixth A'entral, 

 the notch more than twice as wide as deep and with the angle 

 narrowly rounded.

Stout and suboval, very strongly convex, polished, rather 

 sparsel}^ clothed with coarse fulvo-cinereous hairs ; bod^' pale 

 brownish-testaceous in color throughout, the pronotum some- 

 times slightly clouded and the el3'tra with a blackish nubilate de- 

 sign. Length 1.3-1.5 mm.; width 0.95-1.0 mm. 



Rhode Island and New York. This species can be instantly 

 recognized by the long black setse at the sides of the elj'tra, 

 the setie being also more developed on the abdomen at the 

 sides throughout than in any other member of the genus, and 

 there are, besides, four series along the under surface of the 

 abdomen. The epipleurse are narrow, entire, and only slightly 

 vertical externally toward base, but the}' difter from the forms 

 prevailing in the preceding section of the genus in being com- 

 pletely glabrous. The elytral punctures are rather sparse and 

 distinct, feebl}' asperate, each with two short divergent lines,
