transverse impression, very short and thick, distinctly and evenly arcuate, 

 four-fifths as long as the prothorax, very deeply coarsely and densely punctato- 

 subsulcate and dull ; antennse inserted at apical third, the second funicular 

 joint scarcely as long as the first but rather longer than the next two. Pro- 

 thorax not quite as long as wide, the sides in basal three-fourths parallel, 

 straight but convergent near the base, rather prominent at apical fourth, 

 thence convergent and constricted to the apex ; disk evenly convex but ex- 

 ceedingly coarsely, roughly punctato-foveate, the fovea? closely crowded and 

 irregular, with a fine strong carina in apical half, rendered more prominent 

 by a depression in the surface at each side of it. Elytra at base three-fifths 

 wider than the prothorax, two and three-fourths times as long, one- third 

 longer than wide, the sides parallel toward base, sinuate near the apex ; 

 humeri broadly exposed, prominent and obtusely carinate ; disk with unim- 

 pressed series of large deep rather close-set punctures ; intervals flat, the third 

 obtusely tumid at the base, before the middle and through apical third, the 

 fifth more especially from basal third to the subapical impression, the seventh 

 at the humeri and to a greater or less degree along its entire extent. Abdomen 

 with not very dense large and small punctures. Femora with two acute spini- 

 form teeth ; tarsal claws divergent, strongly toothed. Length 5.4 mm. ; width 

 2.5 mm.

May be associated with affinis for the present, but widely dis- 

 tinct from any other described species known to me. 



C carinifer n. sp. — Oblong-oval, feebly convex above, not shining, 

 piceous-black, the elytra, legs and antenna? more or less rufescent ; elytra 

 clothed densely with short recumbent hairs, fulvous, mottled unevenly with 

 whitish, the latter more evident in a transversely lunate area at apical third, 

 also with a few widely scattered extremely short recurved and semi-erect setae ; 

 pronotum glabrous although sparsely setose. Head finely, closely punctate, 

 fulvido-pubescent, the beak long, slender, arcuate, two-fifths as long as the 

 body in the male, finely but strongly punctato-sulcate, separated from the 

 eyes at the sides by a deep vertical groove ; antenna? inserted just behind the 

 extreme apex, very slender, the second funicular joint longer than the first. 

 Prothorax one-fifth wider than long, the sides parallel, broadly, feebly, evenly 

 arcuate nearly to the apex, then rounded convergent and constricted ; apex 

 broadly arcuate and nearly three-fourths as wide as the base ; disk with ex- 

 tremely large deep and closely crowded fovea?, each bearing a short anteriorly 

 directed seta ; surface evenly convex but finely, very strongly carinate along 

 the middle. Elytra one-half wider than the prothorax, two and one-half times 

 as long, one-third longer than wide, ovoidal, the sides becoming parallel toward 

 base ; humeri widely exposed, rounded ; disk with unimpressed series of coarse 

 deep close-set punctures ; intervals flat, the alternate broadly, feebly carinate, 

 the carina? entire. Abdomen coarsely, closely punctate. Legs moderate, the 

 femora uni-dentate. Length 4.3 mm. ; width 2.2 mm.
