to the base. Body elongate and rather slender, more depressed than in 
the preceding species, parallel, dark and uniform piceous in color 
throughout, the legs and antennae rufous; surface shining; punctuation 
coarse, deep and sparse anteriorly, the smooth line of the pronotum 
sometimes subobliterated anteriorly and with its surface more or less 
uneven toward base; head suboval, fully as long as wide, the sides 
parallel and feebly arcuate, the angles broadly rounded to the neck; 
prothorax slightly elongate, a little wider than the head, parallel, the 
sides feebly arcuate, the angles rather distinct; elytra small and de- 
pressed, not quite as long as wide, distinctly shorter than the prothorax, 
somewhat wider than the latter at base and distinctly so at apex, the 
diverging sides nearly straight, the basal angles distinct, the punctures 
not very coarse, very sparse and confused; abdomen parallel, as wide 
as the elytral apex, the punctures minute and rather dense. Male un- 
known; female with the sixth ventral narrowly and strongly lobed at tip, 
the lobe narrowly rounded, the surface feebly and narrowly impressed 
along the middle. Length 7.5mm.; width 1.1mm. New Hampshire.

strongly diverging from base to apex and the surface rather depressed. 
Body elongate, only moderately stout, shining, black throughout, the 
legs and antennae rufous; punctures coarse and sparse anteriorly, 
those of the elytra notably fine, very sparse and confused, of the abdo- 
men minute and dense; head longer than wide, the sides parallel and 
nearly straight for a long distance, the basal angles only moderately 
broadly rounded; prothorax wider than the head, distinctly elongate, 
parallel, the sides broadly, feebly arcuate, the angles rather distinct, the 
broad median smooth area even, generally slightly impressed along the 
median line toward base; elytra at base as wide as the prothorax or 
slightly wider, at apex very distinctly wider, about as long as wide, 
strongly and angularly emarginate at tip; abdomen parallel, scarcely 
as wide as the elytral apex. Male unknown; female with the sixth
