aeneopiceum n. sp. 



Form narrowly fusoid, convex, much smaller than any of the preceding 

 species, blackish-piceous, polished, with a moderate aeneous 

 lustre ; head rather finely, moderately closely punctate, more 

 coarsely and coalescently toward the eyes, the epistoma large, 

 broadly ogival ; prothorax a fourth wider than long, the sides 

 evenly and rather strongly arcuate, becoming sinuate before the 

 moderately acute and everted basal angles and more convergent 

 and straight at the apical angles, which are acute, not at all blunt 

 or everted and only moderately prominent, the surface evenly 

 convex, finely and sparsely punctured medially, gradually densely 

 and somewhat coarsely so laterally, the punctures near the sides 

 separated by nearly their own widths; scutellum moderate, 

 broadly ogival ; elytra elongate, very gradualh' ogivally acute 

 posteriorly from behind the middle, the sides rapidly rounded at 

 the humeri, which are exposed at base, rather less than three times 

 as long as the prothorax and much wider, the punctures only 

 moderately fine, somewhat sparse and irrregular suturally, de- 

 cidedly coarse, close and asperulate, though shallow as usual, 

 laterally, the impressed lines obsolete; abdomen strongly and not 

 very finely, somewhat closely punctured medially. Length 8.2

 behind the middle (9)i strongly convex, moderately shining, the 

 elytra rather dull, black without distinct metallic lustre, the pubes- 

 cence extremely short and inconspicuous ; head rather finely, 

 densely punctate, more sparsely in a small area at the middle of 

 the vertex, each puncture with a small brilliantly silvery seta, the 

 tenth antennal joint nearly one-half wider than long, much more 

 strongly rounded on the inner than the outer side ; prothorax less 

 than a fourth wider than long, but little narrowed anteriorly, the 

 apical angles rather obtuse from above but normally acute and 

 anteriorly prominent from an oblique anterior viewpoint, much 

 defiexed, the basal angles somewhat more than right and not at 

 all prominent but not rounded, the sides evenly and moderately 

 arcuate ; surface strongly, transversely convex anteriorly, rather 

 finely l)ut strongly, moderately sparsely punctate, becoming 

 coarsely and densely so laterally, each puncture with a small sil- 

 very seta, the median line impunctate except near the apex and 

 base; scutellum slightly transverse, somewhat tumid, rounded; 

 elytra rather rapidly acuminate with strongly arcuate sides in 

 apical third, the apical angles acute and simple, the sides arcuate, 

 tlie humeri very gradually lounded to the thoracic base, at the
