tures almost similar, the intervals flatter; dorsal punctures similarly 

 two in number at the third stria. Length 10.2-11.0 mm.; width 

 3.65-4.2 mm. Mexico (Guerrero), — Baron *ruficornis Bates 



7 — Body large and unusually broad, moderately convex, shining through- 

 out, rufo-piceous, the pronotum paler at apex and base and broadly, 

 diaphanously so at the sides, the elytra black throughout, the 

 reflexed margin testaceous; under surface and legs pale rufous, 

 the abdomen black at the sides and apex; dorsal punctures through- 

 out bearing each a very short erect hair; head elongate, more than 

 two-thirds as wide as the prothorax, the eyes only moderately 

 prominent; surface with fine sparse punctures, smooth medially, 

 with a few long plicae antero-laterally; left mandible rather abruptly 

 bent at the middle; antennae dark brown, more rufous basally, 

 a little longer than the head and prothorax, the latter large, two- 

 fifths wider than long, widest slightly before the middle, the sides 

 arcuate, somewhat more converging gradually behind, very broadly 

 and equally reflexed throughout; impressions both feeble but 

 rather evident, the median line fine, widely biabbreviated ; surface 

 with very fine sparse punctulation, becoming gradually coarser and 

 closer peripherally; broadly arcuate median lobe of the base strongly 

 beaded; elytra oblong, feebly inflated behind, nearly one-half longer 

 than wide, two-thirds wider than the prothorax, the rather oblique 

 truncature broadly sinuate medially, the bead rufous, the external 

 angles very broadly rounded; striae rather fine, minutely, closely 

 punctulate; intervals feebly convex, the punctures rather fine and 

 sparse but conspicuous, the dorsal punctures distinct, near two- 

 fifths, adjoining, and at four-fifths, separated from, the third stria. 

 Length 11.8 mm.; width 4.7 mm. Colorado. [Cymindis plani- 

 pennis Csy. nee Lee] ampliata n, sp. 



8 — Setigerous dorsal punctures of the elytra irregular, about three in 

 number on the third interval, about two on the fifth, appearing 

 among the other smaller punctures of the single series on the third, 

 fifth and seventh intervals. Body rather depressed, shining, the 

 elytra alutaceous, rufous in color, the elytra dark brown, with pale 

 margins; femora more flavate, the abdominal tip somewhat dark; 

 head elongate, distinctly narrower than the prothorax, having well 

 developed and somewhat prominent eyes; surface smooth, finely 

 punctulate basally and having numerous plicae toward the sides; 

 antennae rufous, nearly half as long as the body; prothorax less 

 than a fifth wider than long, the broadly arcuate and widely, equally 

 reflexed sides becoming oblique only well behind the middle, the 

 angles obtuse but rather sharply defined, subprominent at tip; 

 base obliquely rounded at the sides; apex sinuate, with very broadly 

 rounded angles; impressions feeble, the stria very fine, subentire; 

 surface smooth, finely punctulate peripherally; elytra almost one- 

 half longer than wide, nearly four-fifths wider than the prothorax, 

 the striae very fine and extremely finely punctulate; intervals 

 alternately flat with very minute confused punctures along the 

 middle, and feebly convex with a single series of minute but more 

 distinct and well spaced punctures, including some larger and
