become more rounded ; the club is scarcely aiuuiluled. The \c^< art- 

 slender, the thighs not clavate, with a feeble indication of two small distant 

 teeth, which become evanescent in the smaller species. The tibia- an- 

 straight, with a sudden bend, and a distinct angle in some species on the 

 outer rdire near the knee ; the third tarsal joint is broadly hilobed, and the 

 fourth is as long as the first, rather clavate, with moderate M/.ed divergent 

 claws. 



The species may be tabulated as follows : 

 Black, with an oblique white spot on each elytron ; tibi;e 



angulated at base 2. 



Brown, variegated ; tibiae not angulated at base 3 



2. Larger, thighs feebly bidentate 1. parochus. 



Small, thighs not toothed 2. bisignatus. 



3. Prothorax and elytra with bunches of black bristles. . , 3. fuscatus.

Middle and Western States. Closely resembles the next species, but is 

 readily distinguished by the greater size (6-6.5 mm.; .24-.26 inch). Tin- 

 two femoral teeth are small and distant. 



2. C. bisignatus Say, Cure. 19; ed. Lee. i, 284; C. luctuosus Boh., 

 Sch. Cure, iv, 146 ; ibid, viii, 1, 348 ; C. misellus Boh., ibid, iv, 120, (fide 

 Boheman). 



Middle, Southern and Western States, to Texas. If the locality of the 

 synonym last cited be correct, it is also found in Brazil. The thighs are 

 sometimes entirely unarmed, sometimes very obsoletely bidenticulate. 

 Length 3.5 mm.; .14 inch ; it does not seem to vary in size, but the white 

 mark of the elytra is sometimes very indistinct. 



C. obliquefasciatm Boh., Sch. Cure, viii, 1, 349, is merely a more 

 distinctly marked variety in which the oblique spot extends from the- 

 se venth to the second stria, becoming a band, and the scattered white dots 

 are more conspicuous. One specimen is only 2.5 mm.; .10 inch long. 



I have three specimens from the Middle States in which the upper sur- 

 face is clothed with brown scales, and the elytral spots are more distinct ; 

 the humeri seem less prominent, and the form more elongate. It seems to 

 be C, pumilus Boh., Sch. Cure, iv, 122. It is probably a distinct specie-, 

 but I can find no other characters upon which to separate it, than tlu^e I 

 have mentioned. 



3. C. fuscatus, n. sp. 



Blackish brown, clothed with pale and dark-brown scales, and bunches 

 of erect blackish bristles. Beak moderately stout, as long as the prothora \ . 

 carinate, striate and coarsely punctured at base, then naked and more 

 finely punctured; antenna inserted nearly at the middle of the beak, 

 slender, club pubescent, indistinctly annulate; head punctured, vertex very 

 finely carinate. Prothorax as wide as long, strongly narrowed from the 

 base, rounded on the sides, constricted in front, deeply and densely punc-
