Elongate-oval, convex, laevigate ; head with frontal sulci 

 strongly divergent posteriorly, two supraorbital setigerous punc- 

 tures on each side; pro thorax with posterior angles rounded, 

 base lobate, marginal channel narrow, •2-punctate; elytra oval, 

 2-punctate on apical third; anterior tibiae 3-dentate. Pronotum 

 and elytra nitid-green with purple tints on discal parts in some 

 lights; inflexed margins of elytra green; head black, occiput 

 virescent on each side at posterior extremity of frontal sulci, 

 under-surface with purple tints behind mentum ; prosternum

 legs black, tarsi and an tennse piceous, palpi reddish-piceous. 



Head large (3 "5 mm. across eyes), convex, smooth; anterior 

 margin with intermediate angles small, triangular, arcuate out- 

 side intermediate angles; clypeus truncate and declivous between 

 intermediate angles; frontal sulci deep, strongly divergent and 

 defining lateral frontal spaces posteriorly; preocular sulcus short, 

 distinct; preocular process, small, rounded externally; supra- 

 orbital sulcus not extending downwards behind eyes to join 

 suborbital channel; eyes convex, prominent; orbits not prominent 

 behind eyes. Prothorax not much wider than head (■2'75 x 4mm.), 

 evenly convex, roundly and strongly declivous to base; sides 

 hardly rounded in middle, very lightly narrowed to anterior 

 angles, widely and evenly rounded posteriorly; anterior angles a 

 little advanced, obtuse; basal lobe strong]}^ developed, rounded; 

 border narrow^ reflexed, sharply sinuate on each side of basal 

 lobe, thicker on basal lobe; marginal channel narrow, a little 

 wider round posterior angles; median line narrow. Elytra oval 

 (6"3 X 425 mm.), convex, evenly rounded on sides; base strongly 

 declivous to peduncle; margin explanate at apex; border roundly 

 reflexed, prominent at humeral angles; inflexed maigin wide,
