the first joint. Body rather stout, only moderately convex, subfusiform, 
black throughout, the legs pale flavate; antennae infuscate, flavate at 
tip; head moderately small in size, much narrower than the elytra, the 
sides parallel behind the eyes fora short distance, the sides being almost 
evenly arcuate from the eyes to the neck; punctures rather coarse and 
close-set; prothorax longer than wide, only very slightly narrower 
than the head, parallel, the sides feebly arcuate, the punctures small, 
rather feebly impressed and sparse; elytra slightly elongate, parallel, 
not very coarsely but strongly, confusedly and closely punctate, much 
longer ard wider than the prothorax in both sexes; abdomen as wide 
as the elytra or slightly wider, the sides parallel and very feebly arcuate, 
the punctures strong and close-set, becoming coarse, scabrous and 
sometimes subconfluent toward the sides. Male with the fifth ventral 
unmodified, the sixth with a deep triangular notch nearly one-half 
deeper than wide, with the angle obtusely rounded and the opening 
abruptly formed and half as wide as the apex; female not differing 
greatly from the male, the sixth ventral narrow, obtusely rounded at tip. 
Length 8.8 mm.; width 1.6mm. New York to Wisconsin, Florida and 
Louisiana. [= latebricola Nord.]....-....- eeeeesceccee ses CinCtumM Say 
Antennae rather slender and only just visibly increasing in thickness from 
the end of the first joint to the end of the sixth, the last five joints ab- 
ruptly much wider, forming a loose parallel club. Body fusiform, 
moderately stout, black, the legs pale flavous, the antennae slightly 
fuscous, gradually paler toward tip; head small, elongate as usual, 
very much narrower than the elytra, the sides converging and evenly, 
strongly arcuate from the well-developed but only moderately promi- 
nent eyes to the neck, which is three-fourths as wide as the head, the 
lateral foveolae very deep and conspicuous; punctures coarse and close- 
set; prothorax slightly elongate, about as wide as the head in the fe- 
male, the sides parallel and feebly arcuate, sometimes broadly angulate 
at the middle, the punctures rather small but conspicuous, somewhat 
sparse and impressed; elytra large, somewhat longer than wide, very 
mucb longer and wider than the prothorax, the punctures rather smal] 
but very deep and close-set, confused; abdomen as wide as the elytra, 
nearly as in cinctum, but less strongly sculptured. Male unknown; 
female with the sixth ventral rather narrow, the tip feebly arcuate.

verging and more arcuate to the neck, the punctures less coarse than 
in cinctum, and twice as widely separated; prothorax large, longer than 
wide, parallel, with the sides evenly and moderately arcuate, slightly 
wider than the head, the punctures rather coarse, deeply impressed and 
widely separated; elytra but little longer than wide, slightly longer and 
wider than the prothorax, the punctures rather coarse, deep and close-
