218 MEMOIRS ON THE COLEOPTERA 



just visibly sinuate in about basal half, finely reflexed, the basal 

 angles somewhat more than right and slightly blunt but not rounded; 

 impressions feeble, the shallow basal foveae at outer sixth rather 

 narrower than usual, opaque; medial stria moderate; elytra rather 

 more than one-half longer than wide, two-fifths wider than the pro- 

 thorax, gradually parabolic in fully apical two-fifths, the sides thence 

 parallel, well reflexed and very feebly arcuate to the broadly rounded 

 humeri; pedicel slightly more than half as wide as the thoracic base; 

 striae one to four more or less evident but very shallow and somewhat 

 irregular; foveae near one and five sevenths. Length 2.4-2.75 mm.; 

 width 0.95-1.15 mm. New York to North Carolina (Asheville),

Antennae decidedly longer, being evidently more than half as long as the

7 Form oblong-suboval, deep black, depressed, moderately shining, the 

 elytral reticulations very strong; legs dark rufous; head nearly two- 

 thirds as wide as the prothorax, the eyes very moderate, less convex 

 than usual; antennae obscure testaceous, three-fifths as long as the 

 elytra, rather heavy, the medial joints three-fourths longer than 

 wide, the third and fourth equal, slender, distinctly longer than the 

 second; basal joint but one-half longer than wide; prothorax barely 

 as wide at base as at apex, three-fifths wider than long, strongly 

 rounded at the sides in about apical third, thence unusually strongly 

 oblique in much more than basal half, becoming just visibly sinuate 

 posteriorly, the angles right and sharp; impressions moderate, the 

 stria joining them distinct; sublateral basal impressions opaque, 

 rather deep and broadly sublinear; margins very finely reflexed; 

 elytra one-half or more longer than wide, only about a third wider 

 than the prothorax, the general outline nearly as in the preceding; 

 surface with six fine and feeble stria?, slightly more distinct inwardly, 

 all except the sutural greatly abbreviated, the foveae as in inornata. 

 Length 2.7-2.85 mm.; width 1.1-1.15 mm - Washington State.

Form oblong-suboval, still more depressed and still less distinctly shin- 

 ing, black, with piceous legs; micro-reticulation strong throughout; 

 head nearly two-thirds as wide as the prothorax, the eyes rather 

 small but prominent; antennae rather thick and obscure testaceous, 

 fully three-fifths as long as the elytra, the medial joints one-half 

 longer than wide, the fourth slightly shorter and evidently thicker 

 than the third, which is longer than the second as usual; prothorax 

 less abbreviated, one-half wider than long, barely as wide at base 

 as at the feebly sinuate apex; sides less finely reflexed, rather more 

 broadly and feebly rounded anteriorly, oblique and straight in about 

 basal half, the angles evidently obtuse but not blunt; surface with 

 feeble but evident transverse impressions and rather fine median 

 stria, the opaque latero-basal impressions shallower than in collaris; 

 elytra one-half longer than wide, fully two-fifths wider than the pro- 

 thorax, gradually parabolic in fully apical third, the sides parallel, 

 well reflexed, almost straight, the humeri as usual; seven striae are
