208 CURCULIONID^E. 



[LeConte. 



the preceding. It differs by the eyes being large, approximate above, so 

 as to narrow the front, and by the hind thighs being thickened, so as to 

 become saltatorial . The claws are appendiculate in our species. 



As in Anthonomus, the funicle of the antennae is 6-jointed in some, 

 7-jointed in other species. 



An excellent analytical table with full descriptions of our species, of 

 which but four were known, has been published by Dr. Horn, in Proc. 

 Amer. Phil. Soc. Nov. 1873, p. 461. To the species described by him must 

 be added the following : 



1. O. rufipes, n. sp. 



Black, very thinly pubescent, with fine whitish hairs ; beak finely punc- 

 tured, head punctured, front narrow, but distinct; prothorax finely punctured; 

 elytra oval, rather flattened, deeply striate, interspaces rugosely punctulate. 

 Antennae and legs yellow, hind thighs dusky, very slightly incrassated ; 

 funicle 6-jointed, second joint scarcely longer than the third; thighs not 

 toothed; claws broadly appendiculate. Length 2 mm.; .08 inch. 



Vermont; two specimens. Smaller than 0. pallicornis, with the eyes 

 less approximate, the hind thighs scarcely thickened, and the legs not 

 black, but ferruginous-yellow. 



2. O. puberulus Boh., Eugen. Resa. Ins., 133. 



California, one specimen. Larger than the other species; black, rather 

 densely clothed with coarse brown pubescence. Prothorax at base twice 

 as wide as the head, not wider than long, narrowed from the base to the 

 tip, punctured. Elytra elongate-oval, nearly twice as wide as the protho- 

 rax; humeri regularly rounded, not prominent; striae composed of rather 

 large, deep but not very close punctures. Antennae testaceous, funicle 

 6-jointed, joints 1-3 elongate; legs testaceous, thighs not toothed; claws 

 broadly appendiculate. Length 3.3 mm. ; .13 inch. 



3. O. parvicollis, n. sp. 



Black, thinly clothed with very fine pubescence, which is not very ob- 

 vious, except upon the scutellum. Prothorax at base a little wider than 

 long, narrowed in front, sides nearly straight; surface densely and strongly 

 punctured. Elytra elongate-oval, more than one-half wider than the pro- 

 thorax; striae deep, punctured, interspaces finely rugose. Antennae and 

 legs black; funicle 7-jointed; thighs not toothed; claws broadly appendicu- 

 late. Length 2.8 mm. ; .11 inch. 



San Mateo, California; one specimen. Resembles 0. niger, Horn, but is 

 larger, with the scutellum less densely pubescent ; the prothorax less 

 coarsely punctured, and the elytra comparatively longer and more regu- 

 larly oval. 



MACRORHOPTUS Lee. 



This new genus is established upon a species from Texas and California, 

 having the aspect somewhat of a small Magdalis, but with the hind angles 

 of the prothorax not laminate, and of the usual obtuse form. It is re- 

 markable for the short thick 6-jointed funiculus, the joints 2-6 being
