132 Dr. B. P. Uvarov’s Notes on the 
femora without any markings outwardly, but with two shining black 
spots inwardly, one occupying the whole basal half and another, 
smaller one, placed at the beginning of narrow part of the femur; 
knees black with brown lobes. Hind tibiae pale with three black 
rings, one at the base and two at equal distances from one another, 
the third being indistinct from above; the number of spines is 11 
at the outer margin and 13 at the inner. Anal segment with two 
short non-contiguous appendages in the middle. Supra-anal plate 
oval, with middle part raised at the base and with short median 
sulcus; its lateral margins with two inflexions and suddenly inflexed 
towards the middle before the apex; the apex itself attenuate in 
short obtuse processus. Cerci longer than supra-anal plate and 
as long as subgenital plate, compressed, towards the apex slightly 
widened and slightly bent downwards. Subgenital plate conical, 
obtuse, hairy. 
The dimensions of the type ($) are: Length of body 22 mm.; 
of pronotum 5 mm.; of elytra 20 mm.; of hind femur 15 mm. 
The female cotypes are much larger than the males, 
and differ in coloration of cheeks, of lateral lobes of the 
pronotum and of the pleurae, which are marked with 
numerous irregular dark grey and black spots and points; 
the hind femora also have numerous obliterate grey points 
in area externomedia and three obliterate greyish trans- 
verse bands at the upper side, prolonged to the inner 
side; hind tibiae are light greyish-slate, with white, black- 
pointed spines. Dimensions of the female are: Length of 
body 42 mm.; of pronotum 9 mm.; of hind femora 27 mm. ; 
of elytra 33 mm. 
This species is closely related to B. brunni, but differs 
from it in its coloration, its shorter and narrower elytra 
(especially in the females) and shorter hind femora. The 
sexual dimorphism in this species is also very striking, as 
it is in B. brunni.
