gin. Abdomen broadly and deeply grooved at middle; surface 

 coarsely and rather densely punctate at middle, becoming strigose 

 laterally, the striae denser and more longitudinal along the lateral 

 margin ; suture between first and second segments nearly straight at 

 middle; last segment deeply, arcuately emarginate at tip, obliquely 

 broadening on each side to the lateral tooth, which is quite small. 

 Femora coarsely, irregularly strigose. 



Length, 27 mm. ; width, 9.5 mm. 



Type locality. — Sandakan, Borneo. 



Type.—C?ii. No. 24672, U.S.N.M. 



Described from a single female from Sandakan, Borneo, collected 

 by Prof. C. F. Baker (Baker No. 14560). This species is closely 

 allied to B. prasina Thunberg and B. fallaciosa Deyrolle. From the 

 former it differs by having the scutellum without any trace of 

 punctures, pronotum more coarsely punctate and the underside 

 fiery red along the middle. From B. fallaciosa it differs by having 

 the pronotum more densely punctate, prosternum flat along front 

 margin, suture between first and second abdominal segments not 

 acutely angulate at middle, underside fiery red along middle, and 

 the last abdominal segment without lateral depressions and more 

 rectangularly emarginate at tip. 



PHILANTHAXIA OBSCURA, new species. 



Oblong-oval, head, pronotum and elytra of a uniform dull, black- 

 ish bronze color, glabrous ; beneath more shining bronzy than above 

 and sparsely clothed with fine, recumbent, cinerous pubescence. 



Head flattened, broadly depressed on vertex; surface densely, 

 strongly reticulate, the reticulation forming a network of small, 

 irregular sunken areas; eyes large, prominent, extending slightly 

 beyond the pronotum on either side ; epistoma wide, anterior margin 

 broadly arcuately emarginate. Pronotum convex nearly two times 

 as wide as long, distinctly narrower in front than behind; sides 

 strongly arcuate and feebly sinuate near the posterior angles, which 

 are produced and acute; anterior margin arcuately emarginate with 

 a feebly rounded median lobe ; base truncate ; surface with a slight 

 impression on each side near posterior angles, punctation similar 

 to that on the head, the reticulation becoming transverse on the 

 disk near the scutellum. Scutellum broadly triangular, nearly two 

 times as wide as long, truncate in front; surface finely granulated 

 and feebly concave. Elytra about equal in width to the pronotum 

 at base; sides strongly sinuate behind the humeri, and nearly parallel 

 to the apical third, then obliquely attentuate to the tips, which are 

 separately narrowly rounded; lateral margin finely serrate; each 

 elytron with a trans^rse depression situated a little before the base 

 and becoming deeper externally; humeri prominent; surface deeply
