5 — Body stout and parallel, very densely punctulate and dull in lustre, 
dark piceous-brown in color, the head rather darker, the legs and an- 
tennae very pale; head large, scarcely at all longer than wide, of the 
usual form otherwise, the eyes well developed and convex; antennae as 
long as the head and prothorax combined; prothorax slightly longer 
than wide, very much narrower than the head, parallel and nearly 
straight at the sides, the anterior angles obtuse but only very slightly 
rounded and somewhat behind apical fourth; elytra parallel, about a 
fifth longer than wide, scarcely two-fifths wider than the prothorax 
and one-third longer; gular sutures very approximate, the intermediate 
surface concave anteriorly, the under surface of the head flat, finely 
but strongly, extremely densely punctulate. Occipital cleft very fine. 
Male unknown. Length2.4mm.; width0.6mm. Alabama. 
crassulus n. sp. 
Body parallel but less stout and rather more convex, dark piceous-brown 
in color, the head and abdomen blackish, the legs and antennae pale 
throughout; head extremely densely punctured and dull, the pronotum 
and elytra less densely so and feebly shining; head nearly as in the 
preceding species, the eyes rather less developed and the antennae 
decidedly shorter, thicker and more incrassate distally, much shorter 
than the head and prothorax combined; prothorax narrower and more 
elongate, nearly a third longer than wide, much narrower than the 
head, the sides distinctly converging and feebly arcuate from the very 
obtuse and rather broadly rounded anterior angles — situated nearly at 
apical third —to the broadly rounded basal angles, the disk broadly 
impressed at each side of the median line toward base; elytra evidently 
longer than wide, about a third wider and one-fifth longer than the 
prothorax; gular sutures slightly less approximate, the intervening 
surface nearly flat. Occipital cleft rather coarse, deep and distinct.

6 — Eyes but slightly convex, not distinctly prominent and unusually small. 
Body very small, slender and parallel, rather shining, the punctures 
throughout very minute and sparse, the pronotum less shining because 
of stronger micro-reticulation; color pale flavo-testaceous throughout, 
the abdomen slightly dusky excepting toward apex; head narrow, 
unusually elongate, the sides parallel, gradually becoming arcuate 
basally, the base narrower than the disk, the angles obtuse but only 
slightly rounded; prothorax distinctly elongate, nearly as long as the 
head and only slightly narrower, the sides very feebly converging from 
the obtusely rounded anterior angles at apical fifth or sixth to the
