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

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 Jess 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 5.4 mm.; width0.8 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, tbe 
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 
rectilineéarly 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
