angle impossible. Body rather large, stouter than usual, moder- 

 ately convex, grayish-black, the upper surface with feeble green 

 metallic lustre, the anterior parts rather shining, the elytra aluta- 

 ceous; legs testaceous, with darker knees and tarsi; head distinctly 

 narrower than the prothorax, with large and prominent eyes; an- 

 tennae slender, nearly black, about half as long as the body, the basal 

 joint testaceous on its under surface; prothorax a fourth wider than 

 long, the sides finely reflexed, slightly more so basally; base rather 

 wider than the apex, strongly obliquely arcuate at the sides; im- 

 pressions subobsolete, the stria distinct, entire; fovese punctulate, 

 sharply linear, deeply impressed, at lateral fourth, only moderately 

 or not at all prolonged anteriorly; elytra one-half longer than wide, 

 five-sixths wider than the prothorax, parallel, with subevenly 

 arcuate sides, not very abruptly more rounded at base; apex some- 

 what obtuse, the sinus rather long, shallow; striae fine, grooved, 

 very minutely subpunctulate, not deeper apically; intervals flat, 

 the third normally with five punctures; met-episterna nearly three 

 times as long as wide; anterior male tarsi feebly dilated, smooth 

 and convex above. Length (d^ 9 ) 9.0-10.0 mm.; width 3.4-3.8 

 mm. Texas texanus Lee. 



Sides of the prothorax and entire habitus of the body very much as in 

 texanus, a little smaller and narrower, similar throughout in color- 

 ation and in the pearly alutaceous lustre of the female, the elytra 

 of the male probably somewhat more polished; head and antennae 

 nearly similar, the third antennal joint much shorter than the 

 fourth; prothorax nearly similar, but with the sides slightly less 

 arcuate, the obtuse basal angles rather better defined at tip, the 

 basal parts much less punctate or impunctate and the foveae less 

 acutely deepened posteriorly; elytra narrower, nearly three-fifths 

 longer than wide, less nearly twice as wide as the prothorax, less 

 narrowed basally than in collisiis; sides somewhat more rapidly 

 rounding at base; striae and intervals nearly similar, the striae not 

 distinctly punctulate, the intervals nearly fiat; punctures of the 

 third five in number; met-episterna twice as long as wide. Length 

 (9) 9-0 mm.; width 3.3 mm. Florida (Enterprise). 



floridanus Lee. 



Sides of the prothorax parallel, feebly or moderately arcuate, becoming 

 straight basally, the tips of the basal angles subacutely and evidently 

 prominent; body smaller in size 9 



9— Prothorax smaller, only half as wide as the elytra, the latter more 

 convex; Atlantic regions. Black, polished throughout in both 

 sexes, the anterior parts feebly metallic-green; under surface black, 

 the legs rufo-piceous; head elongate, only a little narrower than 

 the prothorax, with large and prominent eyes and long, posteriorly 

 oblique anterior impressions; antennae very slender, nearly black; 

 palpi blackish; prothorax as long as wide, the sides finely reflexed, 

 more so at the basal angles; base as wide as the apex, arcuate at 

 the sides, margined; apex feebly sinuate but with sharp angles; 

 impressions barely traceable, the stria fine, impressed, entire; 

 foveae linear, deeply impressed, not much prolonged and not evi-
