prothorax, the eyes not very prominent; front irregularly rugose; 

 antennae slender, half as long as the body, pale brown, blackish 

 basally, the second joint paler than the first or third; prothorax 

 large, slightly wider than long, the sides evenly rounded and well 

 reflexed, becoming gradually moderately sinuate toward the angles, 

 which are obtuse but with bluntly prominent tips; base and apex 

 beaded, the base broadly arcuate, more so laterally, somewhat wider 

 than the moderately sinuate apex, the apical angles narrowly blunt; 

 anterior impression distinct, the posterior obsolete; fovese large, 

 concave, rugulose though not definitely punctate; elytra three- 

 fifths longer than wide, two-thirds wider than the prothorax, the 

 oblique apices broadly and moderately sinuate; striae nearly smooth, 

 coarse, somewhat groove-like, the intervals virtually fiat; met- 

 episterna a third longer than wide; legs long; tarsi with numerous 

 coarse fulvous hairs beneath, the fifth joint with a single fringe of 

 coarse hairs beneath. Length (9) ii.o mm.; width 4.5 mm.

Pronotum smooth or very nearly so, without coarse rugae 8 



8 — Prothorax widest at about the middle of the length. Body stout, 

 rather convex, highly polished and deep black throughout; head 

 rather elongate, with moderately prominent eyes, scarcely over 

 three-fifths as wide as the prothorax, the anterior impressions 

 rather long, slightly oblique; antennae fusco-ferruginous, blacker 

 basally, distinctly less than half as long as the body; prothorax 

 slightly wider than long, the sides strongly rounded medially, 

 oblique and less rounded thence anteriorly and, basally, becoming 

 briefly sinuate near the basal angles, broadly reflexed; basal angles 

 obtuse but sharply defined; beaded base transverse, arcuate later- 

 ally, a little wider than the distinctly sinuate and beaded apex, the 

 apical angles bluntly prominent; anterior impression evident, the 

 stria fine, abbreviated; fove« elongate and moderately impressed, 

 smooth; elytra rather short, scarcely one-half longer than wide, 

 three-fourths wider than the prothorax, the sides evenly arcuate, 

 scarcely at all more so at the humeri, the oblique sinus very feeble; 

 striae deep, smooth, becoming shallower and subpunctate laterally; 

 intervals strongly convex; met-episterna slightly longer than wide; 

 hind wings probably curtailed; legs only moderate in length, the 

 tarsi sulcate externally and with numerous short thick fulvous 

 hairs. Length (9) ii.o mm.; width 4.4-4.6 mm. Mexico (Guer- 

 rero),— Baron *consularis n. sp.

10 — Body deep black, polished and notably convex; head rather elongate- 

 rhomboidal, three-fourths as wide as the prothorax, with rather 

 prominent eyes, the anterior sulci short, parallel; antennae slender, 

 fuscous, black basally; prothorax fully as long as wide if not longer, 

 the sides broadly arcuate and widely reflexed, gradually arcuately
