 Buprestis corusca Fabbicius, Mant. Ins., vol. 1, 1787, p. 176. 



Female. — Elongate, navicular, attenuate in front, more acuminate 

 posteriorly, and narrower behind than in front, glabrous, shining, 

 golden-green above, with a bluish reflection in certain lights, and 

 each elytron ornated with an irregular cupreous spot along lateral 

 margin near apex; beneath golden-green, with a bluish reflection, 

 and the abdomen cupreous, esi^ecially toward the sides. 



Head feebly convex, front flat, triangular, about three-fifths as 

 wide at vertex as at base, with a narrow longitudinal groove on the 

 occiput, and a broad transverse impression behind the epistoma ; sur- 

 face glabrous, with numerous large, deep, irregularly placed punc- 

 tures, and the intervals more finely, obsoletely and irregularly punc- 

 tate. Pronotum regularly convex, with a ix)und deep fovea in front 

 of scutellum, a triangular one on each side along base at middle of 

 elytron, and a narrow transverse groove on each side along the an- 

 terior margin, the groove not extending to the middle, one and one- 

 half times as wide as long, distinctly narrower in front than behind, 

 widest at base ; sides obliquely attenuate from base to anterior mar- 

 gin; anterior margin with the median lobe rather obsolete, but 

 broadly rounded; posterior angles nearly rectangular; surface with 

 numerous large, deep, irregularly placed punctures, the intervals 

 finely, obsoletely, and rather densely punctate. Scutellum smooth. 

 Elytra wider than pronotum at base, widest just behind humeral 

 angles, which are broadly rounded; sides broadly rounded be- 

 hind humeral angles and nearly parallel to just behind the 

 middle, then arcuately attenuate to the tips, which are feebly ex- 

 panded, strongly emarginate and produced into two strong teeth, 

 one at the suture and the other at the lateral margin, the teeth 

 about equal in length; surface nearly smooth, with a few obsolete 

 costae at apex, sparsely punctate, the punctures rather large, irregu- 

 larly placed and tending to form longitudinal rows in some places, 

 the intervals very finely irregularly punctate, and obsoletely rugose. 

 Abdomen beneath strongly convex, sparsely punctate, the punctures 

 rather large, irregularl}^ placed, and from each arises an obsolete, 

 erect hair; intervals finely and densely granulose; first segment 

 broadly but not deeply grooved for its entire length; last segment 

 deeply arcuately emarginate at apex. Prosternum convex without a 

 median groove ; apex rather acute ; surface with numerous large and 

 very fine punctures intermixed. 



Length, 19-22 mm. ; width, 6.5-7 mm. 



Male. — Similar to the female but differ from it in being smaller 

 and having the last abdominal segment nearly truncate at apex, with 

 the preapical margin feebly, arcuately emarginate.
