ing the base; inner fovea coarse, deep and linear, the outer slightly 

 shorter, coarsely incurved along the margin at base, the carina long, 

 coarse, obtuse; elytra oblong-oval, two-fifths longer than wide, a 

 fourth wider than the prothorax, the striae very fine, not at all im- 

 pressed, finely but distinctly punctate, the punctures gradually very 

 fine and lineiform posteriorly; marginal stria very fine, midway 

 between the eighth and margin. Length (9) 19.5 mm.; width 8.3 

 mm. Texas ampla n. sp. 



Scutellar stria long, forming the basal part of the first stria, the true 

 basal part of the latter detached 4 



Scutellar stria wholly wanting 6 



4 Thoracic sides behind the constriction very strongly diverging to the 

 angles, which are acute or much less than right. Body not so stout 

 as usual in this section and more convex, shining, deep black, the 

 legs black; elytra opaculate in the female; head two-thirds as wide 

 as the prothorax, the eyes rather feebly convex; sulci short, coarse, 

 only very feeble on the epistoma; antennae fuscous, black basally, 

 the pubescence gray; prothorax two-fifths wider than long; base 

 and apex equal and subsimilarly, very distinctly sinuate, the sub- 

 apical incised line deep, entire; sides coarsely reflexed, evenly, rather 

 strongly arcuate, the stricture deep though rounded; surface every- 

 where with coarse deep and conspicuous ruguliform lines, especially 

 deep about the foveae; anterior impression feeble, the posterior deep, 

 subangulate; inner fovea narrow, abruptly deep, the outer about 

 half as long, not incurved at base; between it and the marginal gutter 

 the carina is narrow and strong; elytra oval, convex, three-fifths 

 longer than wide, fully a third wider than the prothorax, the sides 

 rather broadly reflexed, the marginal stria midway; striae coarse 

 and deep, coarsely, deeply punctate, both striae and punctures feeble 

 apically; intervals not quite flat. Length (9) 17.0 mm.; width 

 6.3 mm. Florida prominens n. sp. 



Thoracic sides behind the constriction feebly diverging (cf ), or parallel 

 (9), the angles right, sometimes rather blunt; body broader and 

 less convex 5 



5 Body (cf) elongate-oval, moderately convex, highly polished through- 

 out and deep black, the legs also black; head large, not quite three- 

 fourths as wide as the prothorax; eyes moderately prominent; sulci 

 coarse and deep, rather deep also on the basal part of the epistoma; 

 antennae long, extending well behind the thoracic base, black, rufes- 

 cent distally; prothorax two-fifths wider than long; base feebly sinu- 

 ato-truncate, as wide as the rather deeply sinuate apex, the margin- 

 ation of the latter wide, delimited by a fine and entire, rather feeble 

 incised line; sides rather coarsely reflexed, evenly, somewhat strongly 

 arcuate to the stricture, which is shallow, gradual and rounded, thence 

 straight a*nd not very long to the angles; surface with feeble ruguli- 

 form lines, very deep and coarse at the foveae; anterior impression 

 very feeble, the posterior distinct; inner fovea long and deep, the 

 outer two-thirds as long, not incurved at base, the carina strong; 

 elytra oval, three-fifths longer than wide, a fourth wider than the
