474 BULLETIN 63, UNITED STATES NATIONAL MUSEUM. 



Head small, less than twice as wide as long, plane, sides of the frons 

 slightly prominent, punctate, punctures ver}^ feebly subasperate, fine, 

 not dense, each with a small curved and short seta, frontal suture 

 usually not visible. Antennce rather long, quite slender, outer four 

 joints very slightly compressed and scarcely widened, third joint 

 shorter than the next two taken together, fourth scarcely longer than 

 the fifth, the latter and sixth subequal, seventh shorter, eighth feebly 

 shorter than the seventh and slightly triangular, ninth and tenth 

 suborbicular, eleventh subovate. 



Pronotum with margins very broadly foliaceous, the margin more 

 than one-half wdder than the disc, the latter comparatively narrow, 

 longer than wide at middle, very feebly convex, usually with irregular 

 depressed areas ; finely, more or less subasperately and sparsely punc- 

 tate; reflexed margins wider posteriorly and more or less concave, 

 a little more distinctly punctate, punctures less sparse, each with a 

 short curved seta ; apex deeply and feebh" subquadrately emarginate, 

 the emargination about one-half wider than deep, sides almos-t 

 parallel, and scarcely margined; sides evenly but not strongly arcu- 

 ate, moderately converging from base to apex: hase proper feebly 

 arcuate, not margined and about equal to the length, laterally sinuate; 

 apical angles rather narrowly rounded and formed by the advanced 

 foliaceous margins and nearly as long as the head; basal angles are 

 posteriorly prominent, subacute, and projecting backward over the 

 basal angles of the elytra. 



Proyleurae smooth and impunctate: inferior surface of the foli- 

 aceous margins obsoletely punctate. 



Elytra oval to elongate oval; margins broad and reflexed, angles 

 at humeri nearly rectangular and more or less truncate at base, pos- 

 teriorly extending beyond the apex, the two meeting on a line with 

 the suture above the true elytral apex, and defined from the same by 

 a slight groove, borders evenly arcuate froui base to apex or more or 

 less parallel basally; hase evenly but not strongly emarginate; 

 hutneri i)roper broadly rounded and not prominent; sides proper 

 more or less evenly arcuate; aj)e.r ])roper not produced and narrowly 

 I'ounded ; disc plane, feebly convex, at times slightly concave, the 

 inflexed sides nearly straight and oblique, gradually and not strongly 

 arcuately declivous behind ; sarftwe sculptured with approximate 

 series of fine asperate punctures, which become more irregular and 

 slightly denser laterally. Each puncture bears a short and rather 

 robust curved seta. 



Epiplemm narrow, not attaining the humeral margin and not 

 dilated, but gradually narrowing to apex, not defined from the in- 

 flexed sides of the elytra and on the same plane; superior margin 

 obsolete, except near apex; elsewhere represented by a line of punc- 

 tures or a faint groove.
