Head, thorax, scutellum and abdomen, black : two large marks on 

 the head, the margin of the thorax and a small oblique line before the 

 margin, also the margin of the scutellum, flavescent : thorax gibbous, 

 shining : two lines on each segment of the abdomen on both sides and 

 which unite at the apex, also the feet, yellow (G. vahlii, Fabr.). 



<^ , $ . Head with yellow transverse lines : pronotum with a sinuated 

 transverse line on the anterior margin, abruptly curved before the an- 

 terior angle, before reaching the posterior angle ; an. arcuate line on the 

 border of each anterior angle and another similar -intramarginal line 

 around the scutellum, below which is another slender line ; margins 

 of abdomen, transverse lines on each side of the venter, rostrum, feet 

 and antennjB, yellow : some specimens have a small yellow dot on each 

 side of the disc of the pronotum and another like it on each side at the 

 base of the scutellum (P. vahlii, Am. and Serv.) Long 5-6 mill. 

 Differs from B. radians, Voll., in its smaller size and having the intra- 

 marginal flavescent line on the scutellum punctured fuscous. Differs 

 from B. nigriventris, Westw. in having transverse yellow lines on the 

 head. 



Reported from Philippines, Cochin- China, Assam : not uncommon 

 in Sikkim.

Brassy-black : head spotted yellow ; anterior margin of thorax and 

 oblique submarginal line yellow : two marginal lines on scutellum of 

 which the interior line is the broader : venter yellow, with a large discal 

 radiating patch (Voll.). Long 7 mill. Vollenhoven suggests that this is 

 only a variety of his B. vahlii. It is a little larger : over almost the 

 entire head extends a broad yellow patch in which winds a black streak 

 that has its outline twice interrupted : the margin and yellow spots on 

 the pronotum are broader and brighter : the venter black, with the
