elevated and with a faint shallow central furrow, the anterior part 

 tri-foveate ; the sides deeply punctured. Elytra subquadrate, nearly 

 as broad as long, shoulders rounded, posterior declivity abrupt, 

 sides rounded, broadest about middle, apices jointly rounded ; 

 upper surface punctato-striate, the striae very irregular, intervals 4, 

 6 and the apical half of 2 with low rounded tubercles, those at the 

 top of the declivity larger than the others, interval 3 with a small 

 low longitudinal carina, 5 with a large rounded humeral tubercle ; 

 inflexed margins not sulcate, irregularly punctured. Legs with 

 uniform brown scaling and sparse pale setae ; tarsi rather long and 

 slender, the posterior pair with joint 1 longer than 2, the latter 

 slightly longer than broad.

Type in the British Museum {ex coll. Vigors). 



The species is much like a tuberculated specimen of B. flavicollis, 

 Mshl., but apart from the absence of tubercles the latter species 

 differs also in the absence of the central carina on the rostrum, the 

 sulcation of the inflexed margins of the elytra, and the obliquity of 

 the basal carina on interval 3. Described from two examples, the 

 co-type being in the S. African Museum.

Long. 6i-8f ; lat. 3i-4f mm. 



Normal colour black, with uniform light brown scaling, the elytra 

 with two small basal patches of pale velvet-brown scales and a larger 

 sutural one before middle ; sometimes the elytra are dark brown with 

 the tubercles paler ; but in the type the basal patches are black, and 

 there is a narrow sutural black lunule before, and another behind, 

 middle, also the posterior aspect of every tubercle and the thoracic 

 carinae are shiny black. 



Head coarsely punctured, with two oblique carinae uniting anteriorly 

 with the ocular ridges to form a rough W. Bostrum distinctly tri- 

 costate. Prothorax as long as broad, sides rounded in the middle, 

 apex scarcely dilated, as broad as the base ; upper surface with a 

 deep straight central furrow and a shallower furrow on each side of 

 it, the central furrow being bounded by two high smooth carinae ; 

 sides with a large smooth impunctate patch, the remainder being 

 deeply punctured. Elytra oblongo-ovate, shoulders rounded, broadest 

 about middle, the apical declivity rounded dorsally ; the sutural stria 

 and three of the lateral striae regularly punctate, the intervening 

 punctures very irregular ; intervals 4, 6 and the apical half of 2
