marginal, slightly longer but a little narrower one, as well as a 

 third rudimentary and basal, often, however, obliterated ; in the 

 female these bands are somewhat flavescent ; propygidium clothed 

 with white scales, but having a broadly triangular black apical patch, 

 pygidium clothed laterally and along the base with white scales, the 

 denuded interval broad ; legs black, pectus hairy, abdominal seg- 

 ments greatly constricted and covered with white scales ; in the 

 female the parts of the propygidium and pygidium, which in the 

 male are black or denuded, are brown, turning to yellow ; head very 

 hairy, clypeus short, slightly sinuate laterally and with the two apical 

 teeth very long ; prothorax rugose like the head, also densely hairy, 

 very obliquely attenuated latterly in the anterior part, and slightly 

 sinuated past the median part ; scutellum very elongate and sharp, 

 but somewhat broad at the base, sparingly scaly and slightly 

 canaliculate longitudinally in the middle ; elytra strongly ampliated 

 laterally past the humeral part, and diagonally attenuated from there, 

 the humeral callus is strongly developed, but there is a slight depres- 

 sion only on each side of it ; the discoidal part is glabrous, but along 

 the suture and the outer margin there is a series of somewhat closely 

 set, very long and very stiff black bristles ; in the female these bristles 

 are finer, denser, shorter and flavescent, and the intervals between 

 the scaly patches are briefly but densely pubescent ; anterior tibiae 

 tri-dentate outwardly, the two apical teeth are sub-connate, and the 

 basal one is situate far from them ; in the male the trochanters of the 

 posterior legs are simple, the femora are strong, the tibiae are 

 enormously swollen and have inwardly a sub-apical short tooth 

 situated close to and connate wdth the apical spur which is very 

 long and sharp ; the four basal joints of the tarsi are fused with the 

 fifth without any trace of a suture, and this unique joint has beneath 

 a strong hamate tooth and a much smaller one following it, the claw 

 is much longer than the joint, and bi-dentate beneath near the base ; 

 in the female the hind legs are normal and simple. 



Length 8f-9|- mm. ; width 5^6 mm. 



Hab. Cape Colony (Namaqualand). 



In certain parts of this locality the males are uniformly without 

 the two white bands on the elytra, but a few white scales are always 

 visible near the base.
