very remote, less sparse on the sides; prothorax more distinctly 

 elongate, the sides feebly converging, the surface notably convex and 

 unusually coarsely, deeply and conspicuously punctate, the punctures 

 moderately sparse; elytra distinctly wider than the prothorax and but 

 little, though distinctly, shorter, almost as long as wide, the sides very 

 feebly diverging from the base and slightly arcuate throughout, the 

 punctures fine, sparse and partially sublineate; abdomen broader than 

 in amputans, as wide as the elytra. Female not known. Length 5.5 

 mm.; width 0.9. District of Columbia inornata n. sp. 



Body nearly similar in form and coloration but decidedly more slender, the 

 head nearly similar in form and sculpture but only just visibly narrower 

 than the prothorax, the antennae distinctly shorter and relatively 

 thicker, not as long as the head and prothorax, the medial joints scarcely 

 more than a half longer than wide ; prothorax notably narrower and more 

 elongate; fully a fourth longer than wide, the punctures very sparse 

 and less coarse; elytra relatively much smaller, fully as long as wide, 

 with the sides feebly diverging, much shorter but only very little wider 

 than the prothorax, similarly sculptured ; abdomen a little narrower, 

 fully as wide as the elytra. Male with the emargination of the sixth ven- 

 tral similar in general form but still shallower and more gradually 

 formed. Length 6.4 ram. ; width 0.8 mm. New York (Dundee).

10 — Form moderately stout, the head only very slightly narrower than the 

 prothorax, parallel and feebly arcuate at the sides, the basal angles 

 broadly rounded, the punctures small and very sparse; antennae longer 

 than the head and prothorax, stouter, the strongly obconic medial joints 

 distinctly less than twice as long as wide; prothorax less elongate, a 

 fifth or sixth longer than wide, the sides just visibly converging, the 

 punctures rather fine and very sparse; elytra in the male much wider 

 and distinctly shorter than the prothorax, not quite as long as wide, the 

 sides rather strongly diverging throughout, the punctures fine and 

 moderately sparse ; in the female less distinctly wider and shorter than 

 the prothorax, as long as wide, with the sides only very slightly diverg- 

 ing; abdomen not quite as wide as the prothorax in either sex. Male 

 with the fifth and sixth ventrals wholly unmodified on the disk, the former 

 rectilinearly truncate at apex, the sixth rounded at apex as usual, the 

 triangular notch larger, nearly half as wide as the segmental apex and 

 distinctly wider than deep; female rather smaller and more slender than 

 the male. Length 5.3-5.8 mm.; width 0.8-0.9 mm. Massachusetts

 conical but less than twice as long as wide; punctures moderately sparse 

 and distmct toward the sides; prothorax more elongate, a fourth longer 

 than wide, the sides feebly converging and nearly straight, the punc-
