rather narrow, parallel and elongate, much wider than the head, moder- 
ately closely and coarsely punctured; elytra parallel, slightly elongate, 
two-fifths wider and one-fifth longer than the prothorax in the male, 
the punctures rather small but strong and close-set. Male with the 
second ventral unmodified, the third narrowly and moderately im- 
pressed along the middle, more strongly behind; fourth narrowly and 
rather strongly impressed throughout, the fifth also strongly and less 
narrowly, the impression transversely divided in the middle; sixth with 
a broad and shallow cuspidiform emargination, much wider than deep, 
the apical lobes very broadly rounded, the surface densely pubescent 
in the region of the emargination; female differing but little from the 
male, the antennae slightly thicker but equally elongate, the prothorax 
relatively shorter. Length 6.0mm.; width1.05mm. Massachusetts to

Body somewhat similar to the preceding in size and form, the prothorax 
notably larger and broader; elytra pale piceo-rufous in color; head 
slightly broader, finely, not densely punctate, the eyes well developed; 
antennae still longer, equally slender, longer than the head and pro- 
thorax, the medial joints somewhat more than twice as long as wide in 
the male; prothorax broad, but slightly longer than wide, very much 
wider than the head, parallel, the sides feebly arcuate, the angles 
broadly rounded; punctures not very coarse and moderately close-set; 
elytra slightly longer than wide, parallel, about a third wider and more 
than a fourth longer than the prothorax; punctures rather coarse and 
close-set. Male with the third ventral not distinctly impressed, the 
fourth narrowly and rather strongly so along the middle, the fifth 
less narrowly, deeply and subovally so throughout the length, the im- 
pression faintly divided transversely at the middle; sixth with a narrow 
very deep angular notch, much larger in size than that of punctulatus 
and allies, fully twice as deep as wide, with its opening an eighth or 
ninth as wide as the segmental apex, the notch rendered obscure to 
low amplification by reason of the dense obtruding pubescence; female 
unknown. Length 6.7 mm.; width 1.2mm. Indiana? Cab. Levette.

8 — Form narrower and more parallel than usual, black, the prothorax and 
elytra rufous, the latter clouded with blackish toward suture and base; 
head orbicular, rather longer than wide, finely, very sparsely punctate, 
closely so at the sides, the eyes moderate; antennae long and very 
slender, much longer than the head and prothorax, the medial joints 
distinctly more than twice as long as wide; prothorax oblong, distinctly 
wider than the head, a fifth or sixth longer than wide, the punctures 
rather coarse and uneven, not very close-set; elytra quadrate, a fourth 
wider but only very slightly longer than the prothorax, rather coarsely 
unevenly and moderately closely punctate. Male with the fourth and 
fifth ventrals narrowly and just visibly flattened along the middle, not . 
impressed, the sixth with a very minute sharply angulate median notch, 
much deeper than wide and narrower than in punctulatus, almost con- 
cealed by the dense vestiture clothing the surface toward the notch; 
female unknown. Length 7.5 mm.; width 1.15 mm. Iowa.
