than the elytra, fiuely, 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 v?ith 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 scai'cely more than a fourth of the width; sixth 

 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 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 

 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 Jeebiy 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 ihe 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
