deep. TJiis species is easily distinguished from raoh'de by 

 its smaller size, sparser pubescence and much sparser })unc- 

 tuation. 



6— C. lueulentum n.sp. — Forui rather robust, depressed; color black, elytral 

 apices abruptly paler, rufous; a|)ices of the abdominal segments beneath pale; 

 legs pale reddish-ochreous; autenuge uniformly dark rufo-fuscous; palpi 

 piiceous; head and pronotum almost glabrous; pubescence of the elytra and 

 abdomen very sparse. Hue, dark piceo-fulvous and not at all conspicuous: 

 integuments very highly polished. Head short and robust, very slightly 

 wider than long; sides jDarallel and very feebly arcuate; base truncate, angles 

 narrowly rounded; surface moderately convex, rather coarsely and densely 

 jjuuctate at the sides and base, very sparsely so in the middle where there is a 

 rather wide median imi^unctate arta; inteiantenual area impunctate, two 

 setigerous punctures widely separated and very feeble; antennfe slender, 

 nearly as long as the head and prothorax together, second joint scarcely two- 

 thirds as long as the third and distinctly shorter than the fourth, tenth ^s 

 wide as long. Prothorax quadrate, very slightly wider than the head; sides 

 very feebly convergent from apex to base; the latter broadly, evenly and 

 rather moderately arcuate; apex with a distinct median sinuatiou; apical 

 angles somewhat narrowly rounded, basal broadly so; disk moderately con- 

 vex, very finely, rather deeply, evenly and densely punctate; punctures sep- 

 arated by their own widths. Elytra at base very slightly wider than the 

 pi'onotum; sides just visibly divergent posteriorly and feebly arcuate, dis- 

 tinctly more strongly so behind; together broadly and feebly sinuate at apex; 

 disk one-fourth longer than wide and one-third lunger than the pronotum, 

 feebly impressed along the slightly elevated suture except at the apex where 

 the elevation and impressions disappear, rather coarsely, sub-asperately and 

 very densely punctate. Abdomen broad, very slightly narrower than the 

 elytra; border narrow; sides parallel and nearly straight; transversely stri- 

 gate in wavy lines. Letjs slender; first joint of the posterior tarsi as long as 

 the next two together, second as long as the third and fourth, slightly shorter 

 than the fifth. Length 3.7 mm. 



Lake Co., 3. (Mr. Fuchs.) 



Described from the male; the sixth segment is sinuate at 

 apex, the sinus being acutely rounded and but slightly more 

 than three times as wide as deep. This species, although 

 somewhat resembling confrcctatn, may be at once distin- 

 guished by its broader form, much paler elytral apices, 

 highly polished integuments and very sparse pubescence of 

 the el3'tra and abdomen. The sinus of the sixth segment, 

 although rather acutely rounded as in coiitraduin, is relatively 

 distinctly deeper.
