scutellum ; surface rather coarsely and sparsely punctate on the disk ; 

 the punctures hecoming denser and somewhat confluent along lateral 

 margin, with a deep lunate depression on each side, the bottom of 

 which is sparsely strigose. Scutellum triangular, elongate, about one- 

 fourth as long as elytra, the apex very acute ; finely, irregularly, and 

 sparsely punctate over entire surface. Elytra feebly convex, dis- 

 tinctly wider than pronotum at base, and about two and one-half 

 iimes as long, broadly rounded at humeral angles ; sides feebly nar- 

 rowed to apical third, then more strongly attenuate to the apex, 

 which is broadly rounded, with a short tooth at the sutural angle, 

 lateral margin smooth, without serration posteriorly; surface finely 

 and rather densely punctate, the punctures becoming denser along 

 lateral margin; each elytron with two smooth, very feebly elevated 

 costae, the first extending from base to apex and parallel to the 

 suture, the second parallel to the lateral margin, beginning behind 

 the humerus and joining the margin near apex, there are also two 

 smooth intermediate costae which are not elevated and nearly obso- 

 lete. Prosternum gibbose along anterior margin, rather densely and 

 finely punctate, the punctures becoming nearly obsolete posteriorly. 

 Abdomen feebly longitudinally depressed at middle, becoming 

 broadly grooved on last segment ; surface densely and rather coarsely 

 punctate at middle, becoming coarsely, longitudinally strigose toward 

 lateral margin; suture between first and second segments acutely 

 angulate at middle; last segment feebly emarginate at tip, on each 

 side of which is a deep emargination, the lateral tooth long and very 

 acute. Femora coarsely, irregularly strigose. 



Length, 24 mm. ; width, 9.5 mm. 



Tyfe locality.— BuiwAn, Mindanao, Philippine Islands. 



Type.—C2ii. No. 24673, U.S.N.M. 



Described from a single female from Butuan, Mindanao, Philip- 

 pine Islands, collected by Prof. C. F. Baker (Baker No. 14558). This 

 is closely allied to B. pramia Thunberg and B. fdllaciosa Deyrolle. 

 From the former it differs by having the pronotum less densely punc- 

 tate and the sides more broadly margined with a fiery red color, 

 elytra smoother, head fiery red, underside dark greenish-blue with 

 red spots on the side of each abdominal segment, abdomen feebly 

 grooved at middle, with the apex more feebly emarginate. From B. 

 fallaciosa Deyrolle it differs by having the scutellum punctate; prono- 

 tum with the sides more reddish and the posterior angles protruding, 

 head fiery red, and the abdomen feebly grooved at middle. This 

 species is also closely allied to B. mindoreims described by Kerre- 

 mans from Mindoro, but, according to his description, that species 

 has the underside entirely black, and abdomen widely grooved at the 

 middle.
