Coleopterological Notices, V. 517 



B. congener n. sp. — Rather stout, oval, black, subglabrous, impimctate ; 

 legs and anteiinse pale rufous. Head vertical, moderate in size ; epistomal 

 suture very feeble ; anteniisB rather distant, not as slender as in concolor or 

 deflexa, distinctly shorter than the head and prothorax, the third joint not 

 quite three times as long as wide, oblique at apex, much shorter than the 

 second, barely three-fourths as long as the fourth, the latter equal to the 

 sixth, fifth a little longer, seventh and eighth distinctly thicker and more 

 developed on the inner side, club long, subparallel, the ninth joint but little 

 longer than the tenth. Prothorax almost semi- circular in outline from above, 

 fully three-fourths wider than long ; basal lobe strongly rounded ; side mar- 

 gins, viewed laterally, evenly, feebly arcuate ; basal angles acute. Scutellum 

 completely wanting. Elytra about as long as wide, not quite twice as long as 

 the prothorax, a little wider at basal fourth than at base ; apex obliquely and 

 rather widely truncate, the angles moderately broadly rounded ; basal stria 

 entire. Mes-epimera narrow, extending only three-fifths to the coxae ; met- 

 episterna narrow, feebly, gradually narrowed throughout to the humeri, the 

 suture coarse, straight ; epimera distinct, large, the dividing suture fine. 

 Legs long ; posterior tarsi slightly shorter than the tibiae, with the basal joint 

 fully as long as the next three. Length 2.0 mm. ; width 1.25 mm.

This species closely resembles defiexa, but may be known by the 

 short third joint of the antennae, entire basal stria of the elytra and 

 feebly, evenly arcuate lateral margin of the prothorax. From 

 concolor it differs in its much smaller size and in anteunal struc- 

 ture. The male has the fifth ventral bisinuate, the sixth produced 

 in a triangular, narrowly rounded process, flanked by deep, strongly 

 rounded emarginations as in concolor, except that in congener the 

 lobe is larger and more acutely triangular. Three specimens. 



B* deflexa, n. sp. — Stout, broadly oval, subglabrous, the decumbent hairs 

 being remote and very fine as usual, subimpunctate ; under surface, legs and 

 antennae more or less paler, rufo-piceous. Head vertical ; eyes large but not 

 attaining the base ; antennae moderately distant, very slender, not quite as 

 long as the head and prothorax, the third joint rather more than five times 

 as long as wide, distinctly longer than the second, scarcely as long as the 

 fourth, four and five equal and a little longer than six and seven, eight still 

 shorter though scarcely thicker and four times as long as wide, ninth longer 

 than the tenth, both oblique at apex and distinctly more developed on the 

 inner than on the outer side of the axial line. Prothorax from above almost 

 semi-circular, four-fifths wider than long ; basal lobe rather large, strongly 

 rounded. Scutellum completely wanting. Elytra fully as long as wide, twice 

 as long as the prothorax, a little wider between basal fourth and fifth ; apex 

 moderately wide, the external angles broadly rounded ; sutural and marginal 

 striae deep, the basal broadly interrupted. Mes-epimera rather broad, extend- 

 ing two-thirds to the coxae ; met-episterna narrow, exactly parallel, the suture
