distinctly emarginate and angular, and with the apical teeth broad 

 and strongly reflexed ; prothorax gradually narrowed from the base 

 to the apex, but more distinctly so in the anterior part ; deeply 

 and closely punctate, and densely hairy like the head, the scales 

 form a not very distinct margin all round, but those on the disk are 

 few, and very remote ; scutellum moderately elongate, non-scaly ; 

 elytra not much ampliated below the humeral part, but distinctly 

 narrowed towards the apex, faintly sulcate longitudinally on each 

 side of the humeral angle which is well developed, and narrowly 

 striate along the suture, broadly, not deeply, and very irregularly 

 punctate, glabrous except for the usual sutural and outer marginal 

 row of bristles, and the white scales with which it is sprinkled 

 although numerous, are not at all closely set ; the propygidium is 

 covered with closely set white scales, but the pygidium, which is 

 vertical, is bare ; the abdominal segments are not much constricted in 

 the centre and are scaly, and the pectus is very pubescent ; the 

 anterior tibias are tri-dentate, the two anterior teeth are closely set, 

 but not connate, and the basal one is stronger and set at some 

 distance from the apical ones ; the hind trochanters are somewhat 

 dentate, the femora are thick, but not equal in proportion to the 

 size of the tibiae which are extremely swollen and broadly triangular 

 inwardly, the apex of the triangle having a hamate tooth, and at the 

 tip there is, next to the inner spur which is long and slender, a short 

 but distinct tooth ; the four basal joints of the tibiae are short but 

 broad, soldered, and nearly as wide as the fifth joint which is broad 

 but not swollen, the apical claw has a very sharp triangular tooth 

 beneath, and is distinctly curved. 



Female black, with the elytra very dark brown, almost piceous 

 or testaceous red ; prothorax without scales except in the anterior 

 angles of the front margin ; elytra scaleless but deeply punctured, 

 each puncture having a short, greyish or dark seta ; pygidium not 

 scaly as in the male, hind tibiae not swollen and simple. 



Length Si mm. ; width 5-5f mm.

Head and prothorax black, the latter has a distinct marginal band 

 of white scales and is covered with others arranged somewhat in the 

 shape of a cross and having a scaly patch above and below the 

 transverse arms of the cross on each side ; elytra dull red, covered 

 with not very closely set whitish-yellow scales, and having in addition
