 side with a triangular denticulate prominence behind middle; apex acute. Maxil- 

 lae with outer lobe 2- jointed, stout; inner lobe slender, strongly falcate, apex 

 acute, inner side pluridentate (about six or eight teeth equally distant from one 

 another, the odd teeth spiniform). Maxillary palpi rather long; second .joint

 ternal angles rounded and bearing about four minute setules. Labial palpi with 

 penultimate joint rather short, bisetose; apical joint long (a half longer than 

 penultimate joint), club-shaped, compressed, truncate. Antennae setaceous; four 

 basal joints glabrous, first stout, hardly as long as second and third together, uni-

 and fourth; joints 5-11 about equal, longer than third. Prothorax transverse; 

 base emarginate, wider than apex; lateral margins asetose; lateral border thick. 

 Elytra connate, truncate-oval, convex, bordered at base, striate; ten striae before 

 apical declivity, second stria extending backwards to beginning of apical de- 

 (livity; no dorsal iimbilicate punctures; apical margin rounded, not sinuate; or 

 interrupted by an internal plica on each side. Scutellum short, wide. Proster- 

 uum with anterior coxal cavities closed; intercoxal declivity not proininent, nar- 

 row. Mesosternum with epimera reaching coxae. Metasternum short ; episterna 

 short, wide, posterior margin oblique; epimera not visible. Legs moderate: pos- 

 terior coxae contiguous; anterior tibiae short, incrassate, two short stout spinules 

 externally at apex, inner side strongly emarginate, inner spur distant from apex; 

 posterior tibiae elongate, slender. Tarsi: posterior long, slender; anterior in c? 

 with four basal joints dilatate and with spongiose tissue beneath, second and third 

 joints much wider than first and fourth; intermediate about as long as tibiae, 

 two basal joints dilatate and spongiose beneath. Genotype, C. ater SI.

Oblong, convex, black. Head large, convex (2.7 mm. across eyes), without 

 sculpture. Prothorax broader than long (2.7 x 3.6 mm.), widest about middle,
