as long as the prothorax, feebly carinate in the middle toward base; anten- 

 nae long and slender, the scape extending scarcely beyond the eyes, gradually 

 clavate toward tip and clothed throughout with coarse yellowish hairs, funicle 

 distinctly shorter than the prothorax, clothed with coarse bristling hairs, the 

 two basal joints much elongated and equal, seventh very much longer and 

 thicker than the sixth, club elongate, acutely pointed and fusiform. Prothorax 

 nearly as long as wide, the sides parallel, broadly and evenly arcuate, apex and 

 base subequal, the former broadly ai'cuate; ocular lobes strong, fimbriate and 

 attaining the eyes; disk very slightly uneven, closely covered with fine polished 

 tubercles. Elytra two-thirds longer than wide, rather more than twice as long 

 as the prothorax and about one- fourth wider, the sides parallel and broadly 

 arcuate; apex broadly obtuse; luimeri obsolete; base broadly, deeply emar- 

 ginate, the margin acute and prominent at the sides; suture straight and sub- 

 vertical at apex in profile, the intervals alternately flat and convex, the con- 

 vexity more pronounced at the summit of the declivity, the sutural intervals 

 not so distinctly so however as the third ; serial punctures moderate in size and 

 distance, each with a small anterior hair; surface throughout with very small 

 sparse and black subtuberculate punctures. Abdomen shining though rugosely 

 sculptured, coarsely pubescent, with a few sciiles toward the sides near the 

 base, the first suture very coarse, straight, broadly and feebly arcuate in about 

 median third, the second segment barely equal to the next two. Leg.'i long 

 and slender, the anterior strikingly longer and thicker in the male, the ante- 

 rior tibipc internally bent at apex and denticulate within; tibiie densely 

 clothed with long erect hairs, the inner spur of the posterior not visible. 

 Length 9.0 mm; width 3.5 mm. 



California. 



This species is allied to sculptilis, but differs in the color and 

 structure of the legs, tubercular and not confusedly rugose sculp- 

 ture of the pronotum, smaller serial punctures, and presence of a 

 transversely arcuate series of white spots at the summit of the 

 apical declivity. The description is drawn from the male, the 

 fifth ventral being broadly rounded. Two specimens. 



A. dellilis n. sp. — Narrow, subparallel, strongly convex, black, the tarsi 

 and antennai rufo-piceoiis; body clothed with small rounded scales plentifully 

 intermixed with rather short, coarse and brownish hairs, which are very con- 

 spicuous on the elytra, the scales on the head elliptical, dense and subcupreous, 

 becoming sparser on the beak, moderately dense and submetallic on the pro- 

 notum, quite dense and pale brownish on the elytra. Head (juite distinctly 

 less than one-half as wide as the prothorax, the eyes separated by scarcely 

 twice their own width ; transverse impression distinct; beak nearly twice as 

 long as wide and three-fourths as long as the prothorax, rugosely sculptured, 

 not distinctly carinate; antennai long but rather thick, coarsely pubescent, 

 the scape extending to about the base of the eyes, funicle of the usual struc- 

 ture but less elongate. Prothorax not quite as long as wide, the sides stronglj-
