than the elytra, finely, sparsely punctate. Male with a transversely 

 oval setose fovea of moderately large size only slightly behind the mid- 

 dle 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; sixth 

 segment rather strongly, evenly rounded; female wiih 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 longer 

 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 

 slightiy 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 mm.; 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 m 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
