become more rounded ; the clul) is scarcely aunulated. The legs are 

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

 teeth, Avliich become evanescent in the smaller species. The tibite art- 

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

 outer edge near the knee ; the third tarsal joint is broadly bilobed, and tlie 

 fourth is as long as the first, rather clavate, with moderate sized divergent 

 claws. 



The species may be tabulated as follows : 

 Black, with an oblique white spot on each elytron ; t'ib'ive 



angulated at base 2. 



Brown, variegated ; til)i« not angulated at base 3 



2. Larger, thighs feebly bidentate 1. parochus. 



Small, thighs not toothed 2. bisignatus. 



8. Prothorax and eh'tra with bunches of black bristles. . . 3. fuscatus.

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

 readily distinguished by the greater size (0-0.5 mm.; .24-26 inch). The 

 two temoral teeth are small and distant.

3Iiddle, 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. oiliquefasciatus Boh., Sell. Cure, viii, 1, 349, is merely a more 

 distinctly marked variety in which the oblique spot extends from the 

 seventh 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

 but I can find no other characters upon which to separate it, than those I 

 have mentioned. 



3. O. 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 prothorax, 

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

 finely punctured ; antennaj 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-
