Pygidium 5 cmcave at tip and glabrous, the depression 



surrounded by moderately long silken hairs quercus. 



Pygidium ,-t, convex, punctured, hairy. 



Thorax longer than wide ; tooth of femur small rectus. 



Thorax wider than lonjj. 



Tooth of hind femur small, free edge sinuate uuiformis. 



Tooth of hind femur large, triangular, free edge 

 straight. 

 Body above and beneath sparsely clothed, with 



hairs scarcely at all scale-like caryae. 



Body above moderately densely, beneath very 

 densely clothed, hairs beneath broad, scaly nasicus.

Body dark-brown, densely clothed with ochreous scale like hairs, tho- 

 rax at middle broadly fuscous, elytra with fuscous spots irregularly, but 

 closely placed. Rostrum at base punctured. Second joint of funicle 

 longer than the first. Thorax not longer than wide at middle, apex half 

 the width of base, sides in front rapidly diverging, then arcuate and very 

 slightly narrowed to base ; base on each side very feebly sinuate ; disc 

 convex coarsely and densely punctured, median line smooth, surface 

 clothed with ochreous scale-like hairs with broad space at middle (except 

 fine median pale lines), and sides fuscous. Elytra oval, emarginate at 

 base, apices obtusely rounded, disc anteriorly slightly depressed, surface 

 striate, striae punctured, intervals flat, densely rugosely punctulate, sur- 

 face clothed with ochreous scale-like hairs, interspersed with brownish 

 spots. Pygidium densely and coarsely punctured. Body beneath densely 

 clothed with pale yellow silken scales. Legs pale rufo-testaceous, 

 sparsely clothed with silken yellow, short hairs. Femora with a broad 

 triangular tooth, the apex of which is more acute and directed outwards. 

 Length (excluding rostrum) ,32-.44 inch ; 8-11 mm. 



Male. — Rostrum shorter, not longer than the entire body, gradually 

 arcuate, nearly from the base. Dorsum of abdomen with eight segments. 

 Pygidium with moderately long silken hairs. 



Female. — Rostrum often nearly as long as twice the body, straight at 

 basal three-fourths, arcuate at tip. Pygidium scarcely exposed, with 

 short sparse pubescence. Dorsum of abdomen with seven segments. 



This is our largest species, said to live on the chestnut. The color of 

 the elytral pubescence is occasionally uniform. The femora near the tip 

 are very deeply sinuate so that I have described them as being strongly 

 toothed, taking the triangular prominence as a tooth, which is, however, 

 suddenly more slender at apex, and directed outwards toward the apex. 



Occurs from the Middle States, westward. 



B. quercus, n. sp. 



Body brownish, clothed with pale-brown scale- like hairs, nearly uni- 

 form on the thorax, elytra moderately closely spotted with pale orange
