The antennae have the third joint sliort; the bases of the fourtli, fifth, and 

 tenth joints are sparsely, the apex of the eiglith and the whole ninth more densely, 

 l)ubescent white. The spots of the underside are a little smaller than in bicinctus 

 from Talaut. The vittac of the pnmotnm are not half as wide as the patclies of 

 bicinctus, and nearly reach the apical margin. A. bichwtus (1894) and samaranm 

 are probably geographical forms of the same species.
