 next two but thicker; three to six cylindric, almost exactly equal among them- 

 selves and barely as long as wide; seventh }4 thicker, distinctly wider than

 than the eighth and fully }4 wider than long; tenth but little thicker than the 

 ninth, % wider than long, the eleventh stout, ogival at tip and not percepti- 

 bly oblique. Prothorax rather small, rapidly conic, not quite as long as wide, 

 the sides feebly arcuate; apex ^^ as wide as the base, the latter fully % wider

 gradually and rather acutely pointed behind, % longer than wide, more than 

 twice as long as the prothorax and ^5 wider, widest at about basal third, the 

 sides broadly and evenly arcuate; humeral plica distinct, gradually evanes-

 narrow but long and distinct; fovese distinct but small; suture not at all ele-

Readily indentiafible in the small group to which it is assigned, 

 by the somewhat ventricose elytra, uniform black or piceous-black 

 color, with pale legs, slender and sharply pointed clypeal tooth 

 and other characters. The sex of the t3-pes cannot be discovered 

 without dissection. 



27. C laetulum n. sp. — Narrow and elongate-oval, highly polished and 

 impunctate, piceous-black, the elytra scarcely visibly ruf escent ; legs and an- 

 tennae pale ruf o-f erruginous throughout ; pubescence rather abundant, pale in 

 color, coarse and recurved on the elytra, where it is intermingled with sparse 

 erect tactile setae. Head rather large, slightly wider than long, subcircularly 

 rounded behind, the eyes small and not prominent; clypeal tooth well devel- 

 oped, narrow and elongate. Antennse about }4, ^s long as the body, not very 

 stout, the club rather abrupt, its joints increasing just visibly in width; second 

 joint very feebly obconic, rather more than }4, longer than wide, thicker and 

 somewhat longer than the next two; three to six equal in thickness; third, 

 fourth and sixth equal and quite distinctly wider than long ; fifth as long as 

 wide; seventh }4, wider than the sixth and 3€ "wider than long; eighth % 

 thicker than the seventh, ^^ wider than long, narrowed toward apex and 

 widest at the middle ; ninth and tenth slightly wider than the eighth and 

 about '^i wider than long, eleventh somewhat stouter, obliquely pointed. 

 Protliorax about as long as wide, feebly conic, the sides slightly arcuate ; apex 

 ^3 as wide as the base, the latter barely % wider than the head; surface per- 

 fectly even. Elytra narrowly oval, gradually and obtusely pointed behind, 

 widest only slightly before the middle, J^ longer than wide, rather more than 

 twice as long as the prothorax and % wider; sides almost evenly arcuate; 

 humeral plica very short and basal, not very distinct, the subhumeral impres-

 impressions obsolete, the suture not beaded basally. Legs rather long, the
