^ A. Iiuineralis n. sp. — Oblong-oval, moderately convex above, black, 

 the anteniuB and tarsi not x^aler; body clothed with small rounded and closely 

 adherent, dark red-brown scales, with short sparse and whitish hairs inter- 

 mingled, the scales dense and feebly cupreous on the head and beak. Head 

 large, convex, rather more than one-half as wide as the prothorax; eyes sep- 

 arated by between two and three times their own width ; transverse impression 

 feeble ; beak very stout, subcylindrical, thick, thinner toward base in profile, 

 rather feebly but abruptly dilated at apex, one-half longer than wide and 

 slightly shorter than the prothorax; anteiniie very long, inserted almost at the 

 extreme apex, the scape impinging on the eyes and gradually increasing in 

 width from the base, the apex clavate, funicle longer than the prothorax, 

 sparsely setose, the first three joints notably elongate, the first longer than the 

 second or third, the latter equal, three to six gradually shorter, the latter only 

 a little longer than wide, seventh one-half longer than the sixth, obconical, 

 club rather small, narrow, pointed. Proihorax somewhat wider than long, the 

 sides stibparallel and bi'oadly, almost evenly' arcuate; apex'truncate, a little 

 narrower than the base; ocular lobes distinct; disk even in convexity, coarselj', 

 subtubercularly sculptured, the interspaces squamose, the median line very 

 finely and feebly imxn'essed. Elytra two-fifths longer than wide, nearly 

 three times as long as the prothorax and twice as AA-ide; sides parallel and 

 very feebly arcuate behind the obtuse post-basal protuberance; apex acute; 

 base sinuato-truncate, the basal margin not rounded but not prominent at the 

 sides; disk finely and extremely densely squamose throughoixt, the intervals 

 wide, alternately flat and broadly convex, the convexity only slightly more 

 marked behind, except the sutural interval, which becomes strongly promi- 

 nent at the summit of the apical declivity, the latter not very deep, or abrupt 

 but vertical and broadly sinuate in profile. Abdomen densely squamose and 

 sparsely pubescent, the first suture fine and broadly arcuate, the first two seg- 

 ments very large; fifth flat and rather acutely triangular. Leffs long, the an- 

 terior tibiae slightly bent inward at apex, the internal denticles not very dis- 

 tinct; posterior straight. Length 9.0-12.5 mm. ; width 3.75-5.7 nun. 



California (Sta. Barbara), 



The description is taken from the female, and the male is much 

 smaller and narrower, with more oval and less rectilateral elytra. 

 The beak is finely cariuate and with the surface somewhat uneven 

 in broad longitudinal folds. Five specimens. 



IVOMIOrS n.gen. 



In this genus the elytra are oval, with the humeri rounded and 

 the basal margin rather obtuse at the sides, the beak and scrobes 

 as in Amnesia, the legs notably shorter and the hind tibia? not 

 distinctly mucronate. It difters from Amnesia in the fine, broadly 

 arcuate first ventral suture, and, from all the other genera of the 

 Dyslobus group, in the obliteration of the met-episternal suture.
