silver in colour than the rest ; basal three-fourths of the mandibles, labrum, 
clypeus, a line on the lower inner orbits extending above to the ocelli, 
the line roundly incised in the middle and obliquely narrowed above, two 
small transverse lines of equal width below the ocelli, a line on the outer 
orbits, the upper half obliquely narrowed, the prothorax, except for an 
interrupted line on the pronotum and two or three small spots on the 
propleurae, a line along the sides of the mesopleurae, a narrower interrupted 
one on the sides and apex of the scutellum, a large irregular line on the 
middle of the mesopleurae, narrowed above, becoming gradually widened 
below at the base and apex, the basal projection longer than the apical, 
which is roundly incised above, the whole lower part being roundly, broadly 
incised ; the metapleurae yellow, with a large oblique mark on the basal 
half ; the lower part narrowed and roundly curved ; the yellow on the 
pleurae is tinged with rufous ; abdomen with pale olive-yellow bands on 
the apical half of the segments ; the last segment is entirely rufous ; the 
basal black bands on the second and third segments are dilated semi- 
circularly on either side of the middle ; the apical bands are dilated at 
the base in the centre, those on the third and fourth longer and more 
sharply so ; ventral surface black ; the first segment with a broad trans- 
verse yellow band on the outer edge, the second to fifth with smaller 
triangular ones, also on the outer side ; the last with the apical half 
rufous ; legs yellow ; the tibiae and tarsi tinged with rufous ; the 
coxae and trochanters more or less black behind, the fore knees slightly, 
the four hinder more distinctly, a line on centre of the fore femora behind 
on the lower part, a short one on its base, and a broader line on the posterior 
femora above, and the pulvillus, black ; antennal scape pale-yellow ; the 
flagellum rufous, black above ; wings clear hyaline ; the nervures black ; 
the centre of the clypeus is rufous, with two irregularly pyriform black 
spots on the upper half. 
This species is not unlike B. capensis Lep. That species may be 
known by the clypeus being for the greater part black, bv the mesopleurae 
being black, by the yellow on the abdomen not being pallid olive, and by 
the ventral segments having continuous yellow bands.

Black ; the clypeus, except its lower side, the face, the cheeks ; the 
mark on the latter sharply projecting upwards on the outerside and more 
shortly and broadly in the middle ; basal two-thirds of the mandibles ; 
a line on the lower half of the outer orbits, narrowed slightly and gradually 
below, broadly, bluntly bilobated above ; a line on the sides of the pro- 
notum, slightly narrower than the dividing central part, tegulae, a small 
squarish spot on the middle of the scutellum, and three small marks on
