 small marks on ineso- and 

 meta-pleurae, the frenum, and 

 the entire petiolar area, flav- 

 ous; inetathorax scabriculous, 

 with only irregular costae at 

 base of petiolar area ; spiracles 

 linear. Scuiellum and postscutellum flavous, the former with a 

 deflexed and acuminate black spine, nearly as long as its total 

 length. Abdomen nitidulous, closely but obsoletely punctate, 

 black, with the apices of all the dorsal and ventral segments 

 broadly rufescent-flavous ; basal segment sublinear, more than 

 twice as long as apically broad, with the prominent spiracles 

 distinctly before its centre ; ventral valvulae rufescent and 

 subcoucealed. Legs : anterior pairs flavous, with the tibiae and 

 tarsi rufesceut, the femora with a black line below, the basal joint 

 of front tarsi distinctly sinuate and pectinate, and its calcar 

 equally curved ; hind legs black, with the coxae and extreme apex 

 of trochauters with flavous marks, the femora entirely above and 

 their tibiae obscurely internally ferruginous ; calcaria very unequal 

 in length. Wings normal and subhyaline ; radix and tegulae 

 flavous, costa piceous and stigma ferruginous ; areolet normal,

ASSAM : Shillong, Khasi Hills, 6000 ft., on flowers of Spirata, 

 x. 03 (Rowland Turner). 



Type in the British Museum. 



This species has much the facies of the common Palaearctic 

 B. fiictus, F., but is more profusely decorated, and the scutellar 

 spine somewhat relates it to Wesmael's subgenus Coryneplianus. 

 Described from a single male.
