the female, and having in the median part of the disk four equi- 

 distant patches of appressed scales disposed transversely ; elytra 

 livid brown in the male, sub-ochraceous in the female, having on 

 each side a sutural and a supra-marginal band connecting along the 

 apical part, and a discoidal one reaching from the base to past the 

 middle and composed of appressed, lanceolate scales, white in the 

 male, yellow in the female ; propygidium and pygidium entirely 

 covered with dense round scales ; abdominal segments covered with 

 scales ; legs black, scaly ; the head is narrowed laterally, sub-acumi- 

 nate, slightly emarginate at tip and with the two angles of the 

 clypeus not highly dentate ; the prothorax is deeply punctate, and is 

 gradually narrowed laterally from the base to the apex and not 

 sinuate, the two median scaly patches are sometimes obliterated, but 

 the angles of the anterior part are more broadly scaly than the 

 centre of the antei'ior max'gin ; in the male the elytra are more 

 parallel than in the previous species, the humeral callus is strong, 

 but short, and there are on each side three longitudinal very shallow 

 lines which are filled with the appressed scales, they are rugulose 

 and glabrous except for a row of closely set black bristles along the 

 suture and the outer margin ; the pygidium is vertical, the abdominal 

 segments are not constricted in the centre ; the anterior tibiae are tri- 

 dentate outwardly, the two anterior teeth are almost connate at the 

 base, and the basal tooth, which is more robust, is situated at a long 

 distance from the two apical ones ; the hind trochanters are simple 

 and the femora thick and swollen ; the tibije are very swollen, and 

 are produced inwardly at a short distance from the apex into a 

 triangular dentate process scooped beneath, and there is no trace 

 left of the inner spur ; the four basal joints are fused into a short 

 one, but the suture is still indicated by a row of scales, and under- 

 neath there is a sharp spur ; the fifth joint is long, very robust, 

 strongly dentate beneath, and the claw, which is longer than all the 

 joints of the tarsi put together, is sinuate and has a distinct tooth 

 underneath ; the female is much smaller than the male, and the hind 

 legs are slender in comparison, and simple.
