American Caraboidea 295 



Narrower and rather more convex than in the preceding, the 

 elytra parallel and not inflated behind, the latero-basal thoracic 

 sinus shallower and the hind angles bluntly rounded at tip; the 

 color also is green in great part and not indigo-blue. The larger 

 eyes constitute a striking differential feature. The dimensions of 

 leucoscelis, taken from ten specimens, are 12. 8-13. 5 by 4.8-5.7 mm. 



The following species belongs near vafer Lee, but is more elongate : 



Chlaenius pertinax n. sp. — -Form elongate, moderately convex, very 

 dull in lustre throughout above, excepting the polished and sculpture- 

 less head, which is dark green, the pronotum distinct, the elytra more 

 obscure, olivaceous-green; under surface more shining, black, distinctly 

 and rather closely punctate throughout, the legs pale rufous; head 

 rather small, with very prominent eyes, four-sevenths as wide as the 

 prothorax; anterior impressions obsolete; third palpal joint a little 

 longer than the fourth; antenna slender, brown, paler basally; pro- 

 thorax but just visibly wider than long, widest at the middle, the sides 

 broadly arcuate, becoming feebly sinuate at base, unusually finely 

 reflexed, the angles more than right but very sharp; base slightly oblique 

 at the sides, much wider than the apex; surface rather finely, not closely 

 and subevenly punctate throughout, each puncture bearing a stout 

 lustrous hair; transverse impressions wholly obsolete; median line 

 deep, not impressed, biabbreviated; foveae small, linear, feebly im- 

 pressed; elytra two-thirds longer than wide, four-sevenths wider than 

 the prothorax, the sides not very abruptly rounded at base, the sub- 

 apical sinus feeble; margins very finely reflexed, rufescent; striae fine 

 but deep, finely punctate; intervals not quite flat, very finely, feebly and 

 not densely punctate, the hairs small, fulvous; anterior male tarsi 

 moderately dilated, the third joint barely visibly narrower than long. 

 Length (cT) 11.7 mm.; width 4.8 mm. Florida (New Augustine). 



Differs from vafer, found thus far only in Texas, in its narrower 

 form, much less transverse prothorax, the sides of which are parallel 

 for a short distance before the angles, and not converging to their 

 tips as in vafer, and in the finer, less close-set punctures of the 

 elytral surface; in vafer the third joint of the anterior male tarsi 

 is relatively smaller, narrower and more elongate. 



Chlaenius Jacinto n. sp. — Elongate, but less so than in tricolor, the 

 head and pronotum shining and bright cupreo-seneous, the elytra dull 

 and purplish-indigo in color; under surface more shining, black, punc- 

 tate, the abdomen very minutely; legs rufous; head elongate, barely 

 more than half as wide as the prothorax, convex and nearly smooth, 

 the anterior impressions small and punctiform; third and fourth palpal 

 joints equal in length; antennae slender, pale brown, clearer testaceous 

 basally; prothorax between a third and fourth wider than long, parallel, 

 the finely reflexed sides very evenly arcuate from apex to the basal
