before base ; bcasal angles obtusely subrectangular ; posterior 

 marginal puncture placed a little before the base on inner side of 

 lateral channel: elytra truncate-ov-al, deeply striate; third inter- 

 stice 2-punctate, eighth narrow, convex; humeral angles feebly 

 dentate. Head black with a purple tinge ; prothorax nitid, 

 purple-black, violaceous towards sides; elytra dark purple, some- 

 what opaque, lateral channel bright brassy green; under surface 

 and legs piceous. 



Head oval (2-5 mm. across eyes); vertex lightly transversely 

 impressed ; front strongly biimpressed, impressions divergent 

 posteriorly; eyes convex, subprominent. Prothorax broader than 

 long (3-4 X 4 mm.), widest just before the middle, depressed, very 

 faintly transversely striolate; sides lightly arcuate, more strongly 

 and roundly narrowed anteriorly than posteriorly; apex emai'- 

 ginate ; anterior angles rather prominent, obtuse; base wide, 

 emarginate in middle, sloping lightly forward to angles on each 

 side; lateral border widely reflexed, narrower in front of anterior 

 marginal puncture; median line deep, reaching from base almost 

 to apex; lateral basal impressions long, parallel, narrow at bottom 

 (extending almost half the length of prothorax, becoming faint 

 anteriorly); lateral basal impressions a little raised (hardly convex). 

 Elytra truncate-oval (7*6 x 4-8 mm.), wide and truncate at base, 

 strongly sinuate on each side of apex, depressed, lightly declivous 

 to apex, abruptly declivous on sides; basal border curving very 

 little forward to humeral angles on posterior margin, raised into 

 an obtuse subprominent projection at point of junction with lateral 

 border; this widely reflexed, narrow, close to base; three inner 

 interstices very lightly convex on disc, third much wider than 

 first and second at posterior puncture, fifth, sixth and seventh 

 convex, sixth narrower (especially near base), seventh very wide 

 on basal third, eighth narrow, a little wider than ninth on basal 

 half, tenth narrow and feebly developed near apical sinuosity. 

 Intercoxal declivity of prosternum flat, bordered laterally' ; of 

 mesosternum wide, hardly concave. Length 13, breadth 48 mm.
