elytra conspicuously narrowed laterally from below the shoulder 

 towards the apex, bi-costulate on each side, closely and roughly 

 punctured, very briefly pubescent in the posterior part, the elongate 

 patches of yellow scales are disposed as follows : a small one in the 

 base near the scutellum, an elongate basal discoidal, a juxta-sutural 

 reaching from some distance from the base to aliout the median part, 

 and a diagonal one placed outside the humeral callus, reaching to about 

 the same distance, but beginning near the base, tw^o smaller ones 

 situate in the middle of the discoidal part and parallel to each other, a 

 juxta-sutural one reaching nearly to the apex, and a supra-marginal of 

 nearly the same length, the scales of which the bands are formed being 

 small and round ; hind femora robust, swollen, simple but having the 

 trochanters briefly spinose ; hind tibiae sharply carinate underneath, 

 very sharply angular near the knee, briefly mucronate in the lower 

 apical part, and strongly angular on the upper; anterior tibiae very 

 distinctly and sharply bi-dentate outwardly, claws of the anterior and 

 intermediate legs single, cleft laterally ; posterior ones single, simple. 



Female : The shape is similar to that of the male, but the prothorax 

 is clothed with very dense yellowish hairs; the scutellum is scaly, 

 the scales being flavescent white, and the whole surface of the elytra 

 is covered with contiguous yellow scales entirely surrounding the 

 elongated patches which are disposed as in the male, but the scales of 

 which are paler than those forming the background; the hind legs 

 are also robust, but much less so than in the male, the hind tibiae are 

 compressed and have an apical spur. 



Length 7-8 mm. ; width 3|-4 mm.

Male: Black, with the elytra light chocolate- brow^n, sprinkled with 



very numerous minute white scales and having on the outer margins 



of the prothorax three patches of denser white scales somewhat 



connected ; pygidium, sides of abdomen, and pectus very densely 



scaly, the scales white ; clypeus produced into a long triangle, very 



sharp at apex, head very rugose; prothorax with a deep median 



longitudinal groove filled with denser scales, and thickly fringed in 



the anterior margin with very long, blackish bristly hairs; scutellum 



small; elytra obsoletely costulate, conspicuously narrow^ed laterally 



from the shoulder towards the apex, and leaving thus a somewhat 



broad part of the dorsal abdominal segments uncovered, this part is
