infcurned just before base; latei'al channel narrow, a little expla- 

 nate near anterior angles, unipunctate (the puncture 2-5 mm. from 

 anterior angles); median line well-marked; a distinct transverse 

 impression a little before base — between sinuosities of lateral 

 border. Elytra oval(17 x 9*5 mm.), parallel on sides, convex, 

 sloping very gently to peduncle; surface subopaque owing to 

 numerous faint scratches; an elongate-oblique lateral process on 

 each side, just behind middle, this process forming a strong plica 

 rising opposite beginning of apical curve (about l'25mm. above 

 border of elytra) and extending forward about 3 mm. to join the 

 border; lateral border narrow, sinuate about middle of lateral 

 process; each side with four or five submarginal punctures along 

 anterior third, and with three similar punctures along apical 

 curve, another similar puncture in the concavity between the 

 lateral border and the plica. Ventral segments convex, rugulose, 

 impunctate; apical segment smooth, except near sides, unipunc- 

 tate on each side of apex. Posterior trochanters very short; 

 apex wide, roundly truncate : femora rather long; anterior not 

 swollen in middle, lightly incrassate to apex; intermediate 

 shorter than anterior, swollen towards apex, armed on lower 

 side with a long stout straight horn(length 2 mm.); posterior 

 narrow, rot swollen on lower side, upper side subcarinate towards 

 base : four anterior tibise a little bent, stout at apex; posterior 

 long, slender, lightly incrassate, curving lightly backwards: tarsi 

 short, posterior with first joint about one-half longer than second; 

 apical joint stout, cylindrical, hardly narrowed to base. Length 

 30, bi'eadth 9-5 mm. 



^. Diifering greatly from (J, smaller, more robust. Prothorax 

 shorter (7'6 x 7 nira.); basal angles less produced backwards. 

 Elytra much shorter(15 x 9 mm.), more convex and without 

 lateral processes. Prosternum with lateral nodules much less 

 developed; intercoxal part somewhat similar but less developed, 

 almost equally emarginate at base. Legs unarmed; four anterior 

 tibiee not curved; posterior trochanters ovate, obtusely rounded 

 at apex (not widely truncate); posterior tarsi narrower with 

 basal joint longer. Length 24 mm.
