the punctures coarse, rather close-set and irregular in arrangement; 
abdomen but slightly narrower than the elytra, sparsely but distinctly 
punctulate, each segment with a large shallow fovea at base and lateral

unmodified, the sixth ventral obtusely and transversely arcuato-

8— Form rather stout, piceous-black throughout; the abdomen not paler 
at tip, the legs very pale, the antennae dusky except toward base; head 
longer than wide, much narrower than the elytra, coarsely, deeply and 
closely punctured; prothorax rather short, but little longer than wide, 
much narrower than the head, the sides parallel and almost straight, 
the punctures notably coarse, deep, moderately sparse, unevenly dis- 
posed; elytra parallel, about a fifth longer than wide, nearly one-half 
wider and two-fifths longer than the prothorax, rather coarsely, deeply 
and closely punctate, the punctures obscurely serial except toward 
apex; abdomen distinctly narrower than the elytra, strongly, not 
densely punctulate. Male with a transverse setose discal fold at the 
middle of the second and third ventrals, the folds equal in size and 
about an eighth as wide as the segments; lobe of the third segment 
obsolete in specimens at hand; sixth ventral very obtusely rounded at 
tip, becoming subtruncate toward the middle, the edge thinned and 
translucent, the surface notably convex toward the edge posteriorly; 
female not at hand. Length 9.4 mm.; width1.5 mm. Florida to New

Form less stout and rather more convex, the head black, prothorax piceous- 
black, the elytra dark rufous, the abdomen blackish, rufescent at tip; 
head longer than wide, subequal in width to the elytra, less coarsely 
and closely punctate; prothorax distinctly narrower than the head, 
much more elongate than in floridanum and nearly athird longer than 
wide, paralleland nearly straight at the sides, the punctures less coarse 
and about equally close-set; elytra much narrower and more elongate, 
parallel, two-fifths wider and a fourth longer than the prothorax, less 
coarsely but rather more closely punctate, the punctures without serial 
arrangement; abdomen almost as wide as the elytra, the punctures dis~ 
tinct and not close-set. Male with a very strongly developed transyerse 
setose fold near the middle of the second and third segments, somewhat 
asin floridanum, the folds larger, nearly a sixth as long as the width 
of the segment; lobe of the third obsolete in specimens at hand; sixth 
segment narrower, obtusely rounded at tip, the surface cylindrically and 
transversely convex throughout, not at all convex toward tip; female 
unknown. Length 8.0mm.; width 1.35 mm. New Jersey.
