the apex, which is narrowly rounded, one-half longer than wide, coarsely, 'very 

 sparsely punctate, the pubescence short and sparse, but coarse and distinct ; pro- 

 sternum distinctly carinate along the middle of the intercoxal portion. Length 

 1.4 mm.; width 0.55 mm. Pennsylvania cannula, sp. nov. 



Elytra virtually uniform in coloration ; presternum not, or only very feebly, carinu- 

 late along the middle ; elytral punctures fine and more or less close-set 4 



4 — Antennae more elongate, fully half as long as the body in the male, the basal joint 

 relatively longer and subequal to the next three combined ; body small, narrow, 

 parallel and less convex, the sides very feebly arcuate, piceous in color, the elytra 

 paler and brownish-testaceous, generally still paler near, but not at, the apex, the 

 pubescence very short but abundant ; prothorax moderately transverse, sub- 

 parallel, the sides distinctly and evenly arcuate from base to apex, the punctures 

 fine and close-set ; elytra about two-thirds longer than wide, but little wider than 

 the prothorax, not inflated at the middle, somewhat narrowly and parabolically 

 rounded behind, finely and closely punctate. Length 1. 25-1.5 mm. ; width 

 0.5-0.6 mm. Massachusetts to Lake Superior and Iowa pumilio, sp. nov. 



Antennae less developed, much less than half as long as the body, the basal joint sub- 

 equal in length to the next two combined; body more convex 5 



5 — Body parallel and feebly arcuate at the sides, the prothorax well developed, black 

 in color, the elytra piceous, the legs and antennae piceo-testaceous ; pubescence 

 short, moderately abundant but inconspicuous ; prothorax a third to two-fifths 

 wider than long, the sides just visibly convergent and broadly, evenly arcuate 

 from the broadly rounded and margined basal angles to the apex, the punctures 

 fine but deep and only moderately close-set; elytra elongate, three-fourths longer 

 than wide, the sides rather more arcuate near the middle, moderately narrowed 

 behind, at the middle a fourth to nearly a third wider than the prothorax, the punc- 

 ures fine and moderately sparse ; hypomera scarcely at all punctured. Length 1. 78- 

 2.0mm. ; width 0.72-0.76111111. Michigan and Pennsylvania ..patens, sp. nov. 



Body decidedly obese, with relatively much smaller prothorax, similar in coloration, 

 the pubescence still shorter and quite close ; prothorax nearly one-half wider 

 than long, the sides feebly converging from the rounded basal angles to the apex 

 and very slightly sinuate just behind the middle, the punctures fine and close; 

 elytra shorter, three-fifths longer than wide, nearly one-half wider than the pro- 

 thorax, widest at or somewhat behind the middle but without trace of inflation, 

 rather narrowly rounded behind, the punctures fine, only moderately close-set 

 but rather less sparse than in patens; hypomera thickly punctured except at base. 

 Length 1.65 mm. ; width 0.75 jmm. Pennsylvania (Westmoreland Co.) and 

 North Carolina (Asheville) — the single specimen from the latter locality being 

 wholly pale flavo-testaceous, probably from immaturity — and Colorado. 



crassula, sp. nov. 



6 — Body dark in color, or with the head and prothorax darker than the elytra 7 



Body rufo-testaceous in color throughout II 



7 — Pronotum impressed along the basal margin in about median half only, the hind 



angles slightly more than right but exceedingly well marked and not blunt 8 



Pronotum impressed from side to side along the basal margin, the hind angles blunt, 



rounded or very obtuse 9
