ART. 27 NEW BUPEESTID BEETLES FISHER 6 



outer joints bluish black on the under side; pronotuni aeneo-virideous, 

 with the median part irregularly purplish black ; scutellum aeneous, 

 with a bluish or purplish tinge; elytra uniformly purplish black; 

 beneath green, with the tarsi and posterior margin of abdominal 

 segments (except the first at middle) bluish black. 



Head with the front flat, uneven, with an oblong, median eleva- 

 tion behind the epistoma, enclosing a deep, round depression between 

 the antennal cavities, a very strongly elevated, heart-shaped eleva- 

 tion on the vertex, and a narrow, longitudinal groove on the occiput ; 

 surface coarsel}^, irregularly, confluently punctate, the i^unctures 

 sparser on the heart-shaped elevation, sparsely clothed with erect, 

 inconspicuous hairs, the intervals feebly, densely granulose; epis- 

 toma broadly, rather deeply, arcuately emarginate in front. 



Pronotum moderately, uniformly convex, distinctly narrower at 

 apex than at base, and widest at base, with a vague depression on 

 each side near posterior angle ; sides obliquely expanded from apical 

 angles to middle, then nearly parallel to near the posterior angles, 

 which are acute, but not projecting beyond the elytra; anterior 

 margin transversely truncate; base broadly, deeply, arcuately emar- 

 ginate at middle of each elytron, with the median lobe transversely 

 subtruncate in front of scutellum; surface finely, densely, irregu- 

 larly punctate, the intervals vaguely granulose. Scutellum trian- 

 gular, acuminate at apex, the surface vaguely granulose. 



Elytra wider than pronotum at base, and slightly wider at base 

 than behind middle; humeral angles broadly rounded; sides nearly 

 parallel or feebly narrowed from base to near the tips, which are 

 separately broadly rounded, with a distinct tooth near middle of 

 apex; surface very finely, rather densely, uniformly punctate, and 

 each elytron with two or three vague, smooth, longitudinal costae, 

 and a round, deep, basal depression. 



Abdomen beneath densely, finely granulose, rather densely, finely, 

 irregularly punctate, and sparsely clothed at sides along anterior 

 margin of segments with long, recumbent, white pubescence; first 

 segment broadly, longitudinally grooved at middle; last segment 

 broadly, deeply, arcuately emarginate at apex, with a small tooth 

 on each side along lateral margin. Prosternum strongly gibbose, 

 vaguely granulose, sparsely, irregularly punctate, and sparsely 

 clothed with fine, erect, white hairs; anterior margin slightly ele- 

 vated; prosternal process feebly expanded posteriorly, with the apex 

 broadly angulated. 



Female. — Differs from the male in having the last abdominal 

 segment broadly truncate at apex, with a distinct tooth on each side 

 at external angle, and a smaller tooth along the lateral margins. 



Length, 34-38 mm; width, 14-16 mm.
