late tliroughout. Head very distinctly narrower than the prothorax, very feehly 

 convex, with a few fine scattered and indistinct punctures ; median fovea small, ' 

 the surface before it slightly tumid ; suture transverse, rather broadly im- 

 pressed, distinct ; antennal tuberculations rather small, widely distant, rather 

 strongly elevated ; antennae moderate, gradually, rather feebly incrassate ; 

 second joint more robust and very much longer than the third, ninth and 

 tenth not much longer than the eighth, distinctly wider than long. Prothorax 

 scarcely perceptibly narrower than the base of the elytra, one-fourth wider 

 than long ; sides except in basal fourth and apical sixth, parallel and straight, 

 strongly convergent and feebly arcuate to the basal angles, which are very 

 obtuse and broadly rounded, although slightly definable ; lateral angles broadly 

 rounded and not very distinct, apical right, broadly and distinctly rounded ; 

 apex transversely truncate ; base just visibly arcuate ; disk ratlier abruptly 

 and very strongly convex near the apical, basal and lateral margins, finely, 

 feebly, very sparsely and somewhat unevenly punctate, the median line rather 

 broadly impunctate, the median groove almost completely obsolete, only im- 

 perfectly visible under certain angles of illumination. Elijtra very slightly 

 wider and about two-fifths longer than the prothorax, fully as long as wide ; 

 sides nearly straight, scarcely visibly divergent ; disk very feebly impressed 

 near tlie suture toward base, somewhat finely and sparsely but distinctly punc- 

 tate, the punctures separated by rather more than twice their own diameters ; 

 pubescence very sparse, moderate in length. Abdomen parallel, slightly nar- 

 rower than the elytra, very finely and sparsely punctate, beneath more coarsely 

 unevenly and rather sparsely punctate. Length 4.2-4.7 mm.

The hypomera are wide, rather flat but very feebly impressed 

 near the lateral edges, the coxal fissures short, about two-thirds as 

 long as the adjacent hypomeral width and narrowly but distinctly 

 open; the prosternal sutures are almost completely obsolete. The 

 mentiim is flat, scarcely perceptibly and indefinitely concave, coarsely 

 but very feebl}' reticulate, polished, the terminal membranous hypo- 

 glottis strongly developed, nearly one-third as long as the chitinous 

 portion. The anterior angles of the epistoma are finely and very 

 strongly tuberculate in the male. 



This species should be placed near jjolitus. It is rather closely 

 allied to agonus, but differs in its distinctly narrower head, more 

 broadly rounded apical angles of the prothorax, the latter being 

 distinctly less transverse, and in its shorter, more coarsely deeply 

 and densely punctate elytra. 



B. lectlis n. sp. — Rather slender, subparallel, black ; pronotum paler, 

 piceo-rufous ; elytra bright rufous, very broadly clouded with piceous-black 

 toward suture and base ; legs and antennae pale testaceous, the latter slightly
