shining, sparsely covered with fuscous hair, which is 

 longer and paler below the antennae than on the vertex. 

 At the sides and behind the ocelli are bordered by a 

 distinct furrow ; in front of them is a depression from 

 which a straight narrow furrow runs to the base of the 

 antennas. Thorax smooth, shining, impunctate, the 

 upper part fulvous, the sides and sternum paler. Legs 

 fulvous, sparsely haired. Wings from the transverse 

 basal nervure dark fuscous, with a slight fulvous tinge ; 

 the stigma and the nervure in the fuscous part of the 

 wings, blackish ; in the yellowish, yellow. The central 

 part of the petiole above has a few widely separated 

 keels ; the lateral furrows wide and deep ; the central 

 part has the sides at the apex rounded and with a 

 wide short furrow on the inner side. Down the centre 

 of the second segment is a straight keel depressed in the 

 middle, and which does not quite reach the apex of the 

 segment ; on either side at the base is a wide oblique 

 depression reaching near to the apex; at its base are 

 some sharply oblique keels ; the rest of it has a few 

 semi-oblique keels ; the suturiform articulation has 

 throughout straight stout keels ; the other segments 

 coarsely rugosely punctured, except the last, which is 

 smooth, shining, impunctate, and of a pale yellow colour. 

 Is not unlike B. Rothneyi but is larger, the base of 

 the wings more broadly yellow ; the lateral depression 

 on the second abdominal segment is much larger and 

 deeper ; the central keel much more complete and clearly 

 defined and without a smooth triangular base; the base 

 of the antennae yellow, not black, &c.
