thirds as long as the prothorax and one-half longer than ^ide, finely but strongly 

 carinate in the middle in more than basal half; antennae slender and very 

 long, the scape extending beyond the eyes, gradually clavate at apex, the funicle 

 nearly as long as the prothorax, the joints polished but with long sparse brist- 

 ling hairs, all elongate, the first and second greatly so, the first almost as long 

 as the second, the latter not as long as the next two combined, seventh scarcely 

 wider and but little louger than the sixth, club elongate, evenly fusiform. Pro- 

 thorax about as long as wide, the sides subparallel, broadly, almost evenly and 

 rather strongly arcuate; apex subtruncate, slightly narrower than the base, 

 the ocular lobes strong, fimbriate and about attaining the eyes; disk impressed 

 along the median line, more deeply near the apex, rather closely covered with 

 strong polished tubercles. Scutellum depressed, smooth, broadh' triangular, 

 not entering the disk of the elytra. Elytra two-fifths longer than Avide, 

 slightly more than twice as long as the prothorax and nearly four-fifths wider, 

 sides parallel and broadly arcuate; humeri obsolete but with the basal margin 

 acutely prominent at the sides; base broadlj', feebly sinuate; apex rather nar- 

 rowly obtuse; disk strongly, tubercularly swollen on the suture at the summit 

 of the apical declivity, the latter deep and vertical in profile; alternate inter- 

 vals convex, more strongly so and tumid at the summit of the declivity; 

 striae unimpressed, the punctures moderate in size, each with a short anterior 

 hair, the entire surface covered with shining tubercles. Abdomen coarsely and 

 closely punctato-rugose, sparsely and coarsely pubescent, shining and not 

 squamose, the first suture nearly straight, feebly arcuate in the middle. Legs 

 rather long and stout, the anterior tibiae bent at apex and finely denticulate 

 within; hind tibiie with long hairs, the internal terminal uncus distinct. 

 Length 9.0-11.0 mm. ; width 3.6-5.2 mm. 



California (Sta. Critz Mts.). 



The description is taken from the female, the fifth ventral being 

 subtriangular and broadl}" tumid along the middle. The male is 

 smaller and much narrower, with the elytra only about one-fourth 

 wider than the prothorax and the fifth ventral broadl}' rounded ; 

 I can perceive no radical difierences in the legs, but the seventh 

 antennal joint is more decidedly longer and thicker than the 

 sixth. 



A. discors n. sp. — Elongate, strongly convex, black, the tarsi and an- 

 tennae piceo-ruf ous ; body clothed with scales intermixed with short erect dark 

 hairs, the scales linear and dense on the head, spai'se and hair-like on the beak, 

 small, rounded and rather dense between the small tubercles and submetal- 

 lic in color on the pronotum, a little larger, rounded, verj' dense and pale 

 brown throughout on the elytra, a transversely arcuate series of uneven spots 

 at the summit of the apical declivity white. Head about one-half as wide as 

 the prothorax, the head coarsely, densely, the beak still more coarsely, densely 

 and rugosely punctured; transverse impression distinct; eyes separated by 

 barely twice their own width ; beak nearly t\\ice as long as wide, two-thirds
