not so large as usual, three-fifths as wide as the prothorax or less; 

 eyes moderate, the sulci coarse, deep, subparallel and slightly arcu- 

 ate; antenna? fuscous, blacker basally; prothorax two-fifths (cf) to 

 one-half (9) wider than long; base (9) two-thirds the maximum 

 width, less in the male; apex feebly sinuate, broadly and strongly 

 margined; fovese elongate, deeply impressed, the bottom a deeply 

 incised curved line bent anteriorly along and close to the parallel 

 basal part of the sides, the sides strongly rounded, the basal part 

 straight and parallel for a seventh the total length; elytra (9 ) less 

 than one-half longer than wide and nearly a third wider than the 

 prothorax, or (cf) one-half longer than wide and a fifth wider than 

 the prothorax, oval, the sides more rounding at base, the sinus 

 broad but rather deep; striae well impressed, the sixth and seventh 

 much less impressed and finer, the strial punctures strong and mod- 

 erately though irregularly close-set; intervals broadly convex inter- 

 nally; scutellar stria more or less evident but extremely short. 

 Length (icf, 59) 10.7-12.8 mm.; width 4.2-4.9 mm. Texas. 



pantex n. sp. 



Body narrower and less ventricose 7 



7 Elytra strongly shining in both sexes, this assumed in the case of 



vernicata 8 



Elytra strongly alutaceous to subopaque in the female 9 



8 Body convex, deep black and very highly polished; under surface 

 and legs deep black, the coxae rufescent as usual; head large, three- 

 fourths as wide as the prothorax, longer than wide; eyes large, rather 

 prominent, the sulci deep, subparallel; antennae fuscous, blacker 

 basally, extending behind the thoracic base, strongly compressed 

 and with the joints inflated apically on the narrow side as usual: 

 prothorax less than a third wider than long, of the usual form, the 

 sides evenly rounded to the subbasal constriction, thence just visibly 

 converging and straight to the right angles; apex feebly sinuate, 

 broadly, strongly and convexly margined; fovese smooth, very deep, 

 linear, the deeper line curving at base only to inclose the posterior 

 marginal puncture, the carina wholly wanting; sides rather finely 

 reflexed; surface very smooth; elytra very evenly oval, three-fifths 

 longer than wide, a fifth w r ider than the prothorax; sides but little 

 more rounding basally to the obtuse humeri; subapical sinus broad 

 but very evident; striae only moderate in coarseness and impression, 

 the sixth slightly, the seventh much, finer, the scutellar extremely 

 short ; strial punctures fine and widely spaced ; intervals feebly convex, 

 the eighth much broader than any other. Length (cf) n.8 mm.; 

 width 4.4 mm. New Mexico (Alamogordo), H. L. Shantz. 



vernicata n. sp. 



Body nearly as in the preceding but a little larger and somewhat stouter, 

 black, shining; under surface piceous, the legs obscure rufous: head 

 large and elongate, three-fourths as wide as the prothorax; eyes mod- 

 erate and rather feebly convex, the sulci coarse, deep, parallel and 

 contorted; antennae piceous; prothorax much shorter and more 

 transverse than in vernicata, almost one-half wider than long; apex 

 more deeply sinuate, the margin broad and flat, defined by a feeble
