tliirds as lonji a-* the prothorax and one-half longer tlian wide, finely but stronjily 

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

 long, the scape extending beyond the eyes, gradually clavate atapex,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 longer than the sixth, club elongate, evenly fusiform. Pro- 

 thorctx about as long as wide, the sides subparallel, l)roadly, almost evenly and 

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

 the ocular lobes strong, limbriate 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, broadly triangular, 

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

 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 mftrgin 

 acutely prominent at the sides; base broadly, 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; 

 striie unimpressed, the punctures nu)derate in size, each with a short anterior 

 hair, the entire surface covered with shining tubercles. Ahdntncn 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 tibiiB bent at apex and finely denticulate 

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

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



California (Sta. Cruz Mts.). 



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

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

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

 wider than the prothorax and the fifth ventral broadly rounded ; 

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

 antennal joint is more decidedly longer and thicker than the 

 sixth. 



A. discoi'$$ n. sp. — Elongate, strongly convex, black, the tarsi and an- 

 tenna; piceo-rufous; body clothed with scales intermixed witli .sliort erect dark 

 hairs, the scales linear and dense on the head, sparse 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, very dense and pale 

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

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

 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 twice as long as wide, two-thirds
