 Eeddish brown, with bands and spots of sulphur-yellow pubes- 

 cence, the intervening spaces on the elytra more or less densely 

 covered with dark brown tomentum. Antennae with the first four 

 or five ioints rufous, the rest black; third joint shorter than the 

 first, not longer than the fourth ; third to sixth or seventh setose 

 behind especially near the apex. Prothorax widest about the 

 middle^ narrowed towards the base and to a less extent in front, 

 scarcely longer than broad ; the disc with an obtuse, feebly raised, 

 asperate ridge along the middle and a feebler elevation towards 

 each side ; marked with three transverse yellow bands— the first a 

 little behind the front margin, interrupted in the middle the 

 second made up of four transverse spots, the third at the base, 

 this extends downwards on each side and turning forwards, 

 expands into a spot above the coxal cavity. Scutellum yellow 

 Elytra marked each with four yellow bands ; the first, narrow and 

 oblique, placed between the base and the middle; the second, 

 triancrular, just before the middle, its hind border straight and its^ 

 iront^ border oblique, almost parallel with the first band; the third 

 bind straight and rather narrow, placed at a short distance behind 

 tli.^ middle ; the fourth, less distinct than the others, runs parallel 

 M ith the third at a little distance behind it ; the spaces between 

 the bands are dark brown and the anterior yellow band has m 

 front of it a dark brown band which spreads forward at its inner 

 end along the suture and scutellum. Body beneath reddish brown 

 to dark brown, with spots of yellow pubescence on the episterna 

 and bands on the metasternum and abdomen. Hind femora
