Female. — Elongate, broadly rounded in front, more acuminate 

 behind, feebly convex above and similar in shape to angulosa Jac- 

 quelin Duval; above dark metallic-green with the bottom of the 

 punctures cujDreous or purplish, and the entire surface more or less 

 tinged with the same color when viewed in certain lights; beneath 

 brilliant green, with strong cupreous and purplish reflections, the 

 tibiae, tarsi and antennae cyaneous. 



Head nearly flat without any depressions on the front, but with an 

 obsolete longitudinal carina on the occiput ; surface nearly glabrous, 

 coarsely, deeply and rather densely punctuate, the punctures irregu- 

 larly placed and widely separated on the median part, but becoming 

 denser and more regularly placed along the eyes, the intervals 

 irregular in shape, smooth and convex on the top ; epistoma broadly, 

 but not deeply arcuately emarginate in front. Pronotum strongly 

 transverse, two times as wide as long, distinctly narrower in front 

 than behind, and widest just behind the middle; sides strongly 

 obliquely expanded from the apical angles to just behind the middle, 

 where they are strongly obtusely angulated, then more feebly 

 obliquely attenuate to the posterior angles, which are obtusely angu- 

 lated and projecting beneath the elytra; anterior margin feebly 

 arcuately emarginate, with a broad obsolete median lobe; base 

 bisnuate, with a broad strongly angulated median lobe; disk with a 

 broad subtriangular median depression, which is not deeply de- 

 pressed, but sometimes with a fine longitudinal carina at the middle ; 

 surface very coarsely and deeply punctuate, tlie punctures variable 

 in size, becoming confluent in the median depression and on the 

 antero-lateral areas, but more widely separated on each side of the 

 discal depression, the intervals subopaque. Scutellum subquadrate, 

 wider behind than in front, and feebly convex. Elytra feebly convex, 

 slightly wider than pronotum at base ; humeral angles obtusely angu- 

 lated; sides slightly arcuately expanded behind the humeral angles, 

 feebly sinuate at posterior coxae, nearly parallel to apical third, then 

 arcuately attenuate to the tips, which are conjointly narrowly
