 verse impression across vertex; men turn with sinus oblique: pro- 

 thorax subcordate ; sides sinuate before base ; basal angles 

 rectangular ; posterior marginal puncture on border at basal 

 angle ; lateral basal impressions short, deep, foveiform : elytra 

 with wide opaque striae; interstices strongly convex, nitid, eighth 

 and ninth narrow and close together, third 2-punctate. Inter- 

 coxal declivity of prosternum wide, flat; of mesosternum wide, 

 not concave ; metasternal episterna short. Black; antennae and 

 tarsi piceous-red. 



Head smooth; frontal impressions linear, deep, oblique; eyes 

 convex, subprominent; posterior part of orbits swollen, nearly as 

 long as and a little less prominent than eyes. Prothorax smooth, 

 nitid, broader than long (4 x 4*5 mm,), widest a little before 

 middle; apex and base of equal width (3 mm.); sides lightly 

 rounded, shortly and rather sharply sinuate just before base; 

 anterior margin truncate; anterior angles close to head; base 

 truncate; border narrow, widest towards base; lateral channel 

 narrow, uniting with lateral basal impressions posteriorly. Elytra 

 truncate-oval (8-5 x 5-5 mm.), lightly and widely sinuate on each 

 side of apex; interstices 1, 3, 5 wider than others; lateral channel 

 opaque; striole at base of first interstice short, deep; lateral 

 border narrow near base; basal border decidedly raised at humeral 

 angles (subdentate). Ventral segments punctate— first strongly 

 so, three apical ones with a finely punctulate wide depressed space 

 on each side. Length 16, breadth 5*5 mm.
