than the elytra, finely, sparsely punctate. Male with a transversely 
oval setose fovea of moderately large size only slightly behind the mid- 
die of the second ventral, the third with a much smaller discal fovea 
which is well defined and slightly longitudinally elliptical—an excep- 
tion to the general rule, — the lobe rather small and obtusely pointed, 
scarcely extending to the apex of the fourth, its sides diverging to the 
base which occupies scarcely more than a fourth of the width; sixzh 
segment rather strongly, evenly rounded; female with the abdomen 
wholly unmodified. Length 7.7-8.7 mm.; width 1.3-1.35 mm. Texas

22— Body small in size, moderately stout, deep black in color throughout 
except a fine apical border of the elytra and the legs, which are pale 
flavo-testaceous; antennae dusky-testaceous toward base; head very 
distinctly narrower than the elytra, oblong, only very slightly Jonger 
than wide, with the eyes unusually large and prominent and less an- 
terior than usual, the sides behind them parallel or very feebly converg- 
ing and straight to the rounded but unusually distinct basal angles; 
surface alutaceous as in the two preceding species, closely and finely 
punctate; prothorax slightly elongate, distinctly narrower than the 
head, parallel, polished, the punctures coarse deep and close-set; elytra 
slightly elongate, parallel, much wider and longer than the prothorax, 
the punctures but slightly less coarse than those of the pronotum and 
dense, arranged without order; abdomen much narrower than the 
elytra, alutaceous, finely and not closely punctulate. Male with a fine 
transverse setose fold at the centre of the second ventral, occupying 
median eighth or ninth of the width, the third also with a similar 
though slightly shorter and still finer setose discal fold, the lobe very 
broad and obtusely rounded, occupying nearly median three-fifths and 
not extending to the apex of the fourth; sixth broadly rounded at tip; 
female with the abdomen wholly unmodified, the sixth ventral truncate 
at tip, with the surface feebly ascending, paler and translucent at the 
edge. Length 6.8-7.5 min.; width 1.2-1.28 mm. Florida to Texas

23 — Body very small, notably slender and parallel in form, dark testaceous 
and polished throughout, the legs pale flavo-testaceous; head well de- 
veloped, distinctly elongate, a little wider than the elytra, parallel and 
straight at the sides, the basal angles more broadly rounded and the 
eyes smaller and less prominent than in despectum, the punctures coarse 
and rather sparse; prothorax distinctly elongate, parallel, narrower than 
the head, still more coarsely and nearly as sparsely punctate; elytra at 
least a fourth longer than wide, parallel, distinctly wider than the 
prothorax but only as long as the latter in the female and a little shorter 
in the male, the punctures relatively very coarse, not close-set, serial; 
abdomen scarcely narrower than the elytra, rather coarsely, unevenly 
and not densely punctulate. Male with a rather long and strongly setose 
fold well behind the middle of the second ventral, the third with a 
circular perforate discal fovea before the middle, the lobe obsolete in 
specimens at hand; sixth ventral obtusely rounded at tip; female with 
a very Small transverse setose fold well behind the middle of the second
