adherence to a common type characterizes also the individuals of 

 the various species, there being but little variability throughout 

 extended series, even in size of the body, so that with some study, 

 there can be no more than the usual uncertainty in recognizing 

 species. 



1. C. repletum n. sp. — Stout, polished and impunctate; head blackish, 

 the prothorax slightly paler, the elytra dark rufo-testaceous throughout ; ab- 

 domen blackish, slightly pale toward tip; legs and antennae bright rufo-tes- 

 taceous; pubescence long and abundant, flavous, darker on the prothorax. 

 Head about as long as wide, strongly parabolic behind the eyes, which are 

 notably small and but slightly prominent; clypeal margin strongly toothed at 

 the middle. Antennae % as long as the body, gradually but rather strongly 

 incrassate toward tip, the three basal joints decreasing slightly in thickness; 

 second nearly twice as long as wide; three to six differing but little among 

 themselves and about % longer than wide, seventh but slightly thicker, }4 

 longer than wide ; eighth elongate-oval, beaded at base as usual and % longer 

 than wide; last three joints increasing very slightly in thickness; ninth and 

 tenth oval, narrowed at base, the latter not longer than wide, the former 

 slightly elongate; eleventh oval, gradually and obliquely pointed, not as long 

 as the two preceding. Prothorax conic, the sides feebly arcuate, the apex 

 about 3^ as wide as the base, the latter broadly arcuate and scarcely more than 

 }^ wider than the head ; disk with two large rounded and excessively feeble con- 

 tiguous impressions at the middle, near the basal margin. Elytra not quite 3^ 

 longer than wide, twice as long as the prothorax and about ^ wider, oval, the 

 sides evenly arcuate, somewhat obtuse at apex; humeral plica feeble; sub- 

 humeral impression large but feeble, the two fovese approximate and not 

 strong; surface strongly impressed at the suture near the base, the suture 

 finely but strongly elevated basally. Legs well developed, the femora all 

 strongly clavate, but, as usual, decreasingly so posteriorly. Length 2.1 mm. ; 

 width 0.9 mm. 



Arkansas (Carlisle), Mr. Wickham. 



The individual before me is without doubt a male, and the 

 species may be known by its large size, strong elytral impressions, 

 elevated suture and inflated hind body. The two approximate 

 impressions of the pronotum are so feeble, that, were they not 

 symmetrically placed in the unique type, I should be disposed to 

 regard them as spurious and accidental ; it is more than probable 

 that they are inconstant and may disappear altogether. 



2. C optatum n. sp. — Elongate-oval, moderately stout, polished and im- 

 punctate, dark piceo-castaneous, the elytra dark rufous throughout but blackish 

 along the suture ; abdomen pale and somewhat yellowish ; legs and antennae 

 dark rufous ; pubescence long and abundant, pale, dense and bristling ante- 

 riorly. Head nearly as long as wide, broadly parabolic behind the eyes,
