zYaoPLN'i. 263 



A specimen from Owen's Valley, California (Dr. Horn), is much less con- 

 spicuously colored. 



5. C. quercus Gyll., Scli. Cure, iv, 650; Zygo-ps quercus Say, Cure. 30; 

 eel. Lee. i, 386. 



Middle States; two specimens. The antennae in this species are dark or 

 piceous; the scales are smaller than in C. operculatus. The prothorax is 

 less elongate, and is rather suddenly- narrowed near the tip; it is coarsely 

 punctured and marked with three while basal spots, the side ones being 

 larger. The elytral pattern seems to be the same as in C. adspersus, but is 

 partly abraded in my specimens, and it apparently differs from that species 

 chiefly by the darker antennie and less elongate prothorax. 



6. C longulus, n. sp. 



Elongate, brown, beneath densely clothed with white scales, head and 

 base of beak also densely clothed with white scales; front narrower than 

 in C. operculatus; beak rather stout, black, nearly smooth; antennaj pale 

 testaceous, second joint of funicle longer than third. Prothorax evi- 

 dently longer than wide, scarcely narrowed in front, feebly constricted 

 near the tip, rather finely granulato-punctate, with three small basal, and 

 two discoidal spots of white scales. Elytra denselj' clothed with brown 

 scales and a pattern of white markings, consisting of an irregular oblique 

 band from the humerus to the middle, and a less oblique one behind the 

 middle, united with the former at the suture; there are also scattered dots 

 of white scales. Legs banded and speckled with brown. Length 3.3 mm., 

 .09 inch. 



California (Geysers), and Utah ; Canada, Pettit. The scales of this 

 are much smaller than in the preceding and following species. 



7. C. binotatus, n. sp. 



Black, densely clothed with dark gray scales, which are small on the 

 prothorax, and large on the elytra, upon each of which is a ver}- large sub- 

 quadrate, blackish brown spot. Head and base of beak clothed with scales; 

 beak and antenna? black; front narrower than in C. operculatus. Protho- 

 rax scarcely longer than wide, slightly narrowed in front, verj' feebly con- 

 stricted near the tip, densely and deeply punctured, punctures concealed by 

 small rounded gray scales. Elytra with deep punctured stria? and some- 

 what convex interspaces, densely covered with larger rounded gray scales; 

 each with a large spot, covered with dark brown scales, oecupying nearly 

 the middle third of the surface, and extending from the first or second stria 

 to the eighth. Length 3.5 mm. ; .10 inch. 



Pennsylvania and Texas; two specimens. 



8. O. lunatus, n . sp. 



Blackish brown, head and base of beak clothed with white, hair-like scales, 

 beak more slender than usual, smooth, front very narrow, linear; antennae 

 nearly black, second joint of funicle longer than third. Prothorax longer 

 than wide, slightly and gradually narrowed in front, sides scarcely rounded;
