California (Santa Barbara). 



The male type has tlie 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 scarcel}^ visibly smaller when compared with the protho- 

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

 being at its widest part full}' as wide as the. elytral base, which in 

 the male is much narrower. Four specimens. 



The epipleura? 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. explaiiatus n. sp.— Oblong, broad, sulxlepressed, polished, black, 

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

 pale rufous; legs piceous-black, the tibiae and tarsi ruf escent ; antennse blackish, 

 rufescent toward base; pubescence fine, sparse, rather sliort and cinereous, 

 intermixed ^vith short fine 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 widely separated ; epistoma 

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

 size, not very convex; antennse slightly longer tlian 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 apex, the latter feebly arcuate, much narrower tlian the base, 

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

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

 coarsely but sparsely punctate, smooth, not at all rugose toward the sides. 

 Elytra a little more than one-half longer than wide, nearly one-half ^\■ider than 

 the prothorax, parallel, feebly dilated with the sides slightly arcuate, becom- 

 ing parallel very hear the base; apex broadly, evenly rounded, the sutural 

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

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

 deep and sparse. Abdomen very sparsel}^ and rather coarsely cinereo-pubes- 

 cent. Length 3.3 mm. : width 1.4 mm.
