lateral edges reflexed ; puuctures not very coarse but strong and rather sparse ; 

 edges toward apex tinely serrulate. Abdomen not very densely but coarsely 

 cine^eo-pubescent. Length 2.7 mm. ; width 1.25 mm. 



California (Santa Barbara). 



The male tj'pe has the fifth ventral distinctly longer than the 

 fourth, and broadly flattened or impressed and truncate at apex 

 almost throughout the entire width, the impression obsolete to- 

 ward base, more broadly' toward the middle. In the female the 

 head is scarcely visibly smaller when compared with the protho- 

 rax, but the latter is distinctlj^ wader in reference to the elytra 

 being at its widest part fully as wide as the elytral base, which in 

 the male is much narrower. Four specimens. 



The epipleurjB are very wide, almost horizontal and finely, 

 sparseh' punctate and pubescent, becoming obsolete at a consid- 

 erable distance from the elytral apices and scarcely at all curved 

 inward posteriori}", 



2. A. explanatus u. sp. — Oblong, broad, subdepressed, polished, black, 

 without metallic lustre, the elytral apices and abdomen, except near the base, 

 pale rufous; legs piceous-black, the tibiie and tarsi rufescent;antenna3 blackish, 

 rufescent toward base; pubescence tine, sparse, rather short and cinereous, 

 intermixed Avith short tine erect hairs of the same color; marginal cilia short. 

 Head three-fourths as wide as the prothorax, smooth throughout, rather coarsely 

 but sparsely punctate, the impressions large and ^videly separated; epistoma 

 very short and broad; labrum transverse, truncate at apex; eyes moderate in 

 size, not very convex; antennae slightly longer than the prothorax, serrate, all 

 the joints asymmetric, the fifth and sixth subequal and rather wider than seven 

 to nine, tenth moderately transverse. Prothorax about one-third wider than 

 long, the sides strongly arcuate, becoming gradually convergent and less arcu- 

 ate toward a^iex, the latter feeljly arcuate, much narrower than the base, 

 which is still more arcuate; basal angles extremely broadly rounded and wholly 

 obliterated, the ajjical deflexed and broadly rounded; disk convex, rather 

 coarsely but siiarsel}' punctate, smooth, not at all rugose toward the sides. 

 Elijtra a little more than one-half longer than wide, nearly one-lialf wider than 

 the i)rothorax, parallel, feebly dilated with the sides slightly arcuate, becom- 

 ing parallel very near the base; apex liroadly, evenly rounded, the sutural 

 angles right and scarcely at all blunt; disk subexplanate and with the edge 

 strongiy serrulate externally at apex; lateral edges reflexed; punctures coarse, 

 deep and sparse. Abdomen very sparsely and rather coarsely cinereo-pubes- 

 cent. Length 3.3 mm.; width 1.4 nun.

The single specimen before me is a female, having the fifth ven-
