acutely rounded behind, and with the humeri entirely obsolete, in 

 the complete absence of scutellum, and in its small eyes. The 

 elytra are probably subconnate. In its short deeply sinuate pro- 

 sternum, short beak, and toothed claws, Oopterinus resembles 

 Otidocephalus.

Oval, piceous, the elytra and legs still paler, the upper surface 

 with a few rather short, semi-ei'ect, widely scattered whitish setsB. 

 Head sparsely but strongly punctate, the interocular surface impunc- 

 tate but with a small rounded median fovge ; eyes remarkably small, 

 coarsely granulated, separated by fully their own width ; beak rather 

 thick, feebly arcuate, almost as long as the prothorax, strongly 

 punctured at the sides and with a short longitudinally impressed 

 line between the antennae, the latter slender, the second funicular 

 joint obconical, one-half longer than the third ; club oval, rather 

 sparsely pubescent. Prothorax longer than wide, strongly narrowed 

 and feebly constricted toward base, very coarsely, deeply, slightly 

 unevenly but rather closely punctate. Elytra ovate, two-thirds 

 longer than wide, widest before the middle, the sides evenly rounded ; 

 humeri obsolete ; punctures very fine, dispo.sed in even series which 

 are entirely unimpressed except near the base. Legs very slender, 

 the femora broadly emarginate near the apex but not toothed. 

 Length 3.3 mm.; width L3 mm. 



The single specimen in the LeConte cabinet has no indication of 

 locality, but the original type, in the cabinet of Mr. Ulke, is from 

 Maryland.

The following rather isolated species may be referred at present 

 to the groups outlined by Dr. LeConte. 



C. COnipositUS n. sp. — Oblong-oval, moderately convex, not at all shin- 

 ing, black, the legs and antennse rufo-piceous ; elytra clothed densely witli 

 short recumbent hairs, piceons in color, fulvous along the ridges and yellowisli 

 in three elongate spots at the base of each, the two outer coalescent, the 

 pronotum more sparsely pubescent, with a few whitish hairs scattered in an 

 oblique line at each side ; upper surface throughout bristling with short stitf 

 erect setse. Head and beak densely hispid with short bristles and more 

 recumbent hairs ; front foveate ; beak separated from the liead by a deep
