and is much longer than wide, with the surface longitudinally and 

 broadl)^ convex ; also, at lateral fourth of the third ventral segment 

 and at the middle of its length, a peculiar oblique lamelliform bilobed 

 and setose process. This species is readily separable from any of 

 the others by the peculiar form of the head. 



A. brCTipeniie n. sp. — Minute, somewhat stout, convex, uniformly 

 dark rufo-testaceous. polished, subimpunctate ; pubescence short, subrecum- 

 bent, rather abundant. Head distinctly shorter and narrower than the pro- 

 thorax, wider than long ; foveae small but deep, distant by one-half the total 

 width, not distinctly spongiose, connected by a deep entire sulcus ; antennal 

 tubercles rather prominent ; eyes moderate, from above slightly prominent, 

 not quite as long as the tempora, the latter subparallel, feebly rounded and 

 almost as prominent as the eyes ; antennje two-thirds longer than the head, 

 second joint stouter than the first ; under surface with sparse erect and finely 

 capitate setse. Prothorax slightly wider than long, the base and apex sub- 

 equal, widest before the middle where the sides are broadly, evenly rounded 

 to the apex, abruptly convergent and broadly, feebly sinuate from the middle 

 to the base ; sulcus fine, deep, at basal fourth, broadly, very feebly angulate 

 but not perceptibly dilated in the middle ; lateral foveas large and nearly 

 nude. Elytra not quite one-half longer and three-fourths wider than the 

 prothorax, transverse ; discal stria extending to apical third. Abdomen much 

 longer and slightly narrower than the elytra. Legs moderate, the two ante- 

 rior femora, and especially the intermediate, incrassate in the male. Length 

 0.9 mm. ; width 0.3 mm. 



California (Sta. Cruz Co.). 



A single pair exhibiting scarcely any sexual difiFerences in general 

 form. The venter of the male is not tuberculate near the sides, but, 

 as usual, the second ventral is broadly feebly impressed at lateral 

 sixth especially toward base. The short elytra of this species will 

 distinguish it at once from any other. It is the smallest of the 

 genus.

The following interesting forms belong to the first division of 

 LeConte, but differ altogether hova ferox and ionse in the type of 

 male sexual modification, having the anterior legs simple but the 

 posterior more or less distorted. This small group may also pos- 

 sibly receive confinis Lee, which is known only by the unique 

 female type.
