Description

For a key to the terms used see Lepidopteran glossary
Males and female (below) of anticrates

Race anticrates: Upperside ground colour white with a very faint tinge of green in fresh specimens. Fore wing: subbasal transverse black band somewhat attenuate posteriorly ; in the cell the preapical band subtriangular, sometimes not extended to the median vein; the terminal series of spots of the ground-colour linear as in hermocrates, posteriorly those become lunular in shape. Hind wing: the discal black band obsolescent, only faintly defined near costa and at posterior end; terminal black band and terminal lunules of the ground-colour as in Graphium nomius but narrow ; grey subcaudal patch as in Graphium nomius. Underside: similar to the underside in Graphium nomius with the following exceptions—the black markings of the upperside entirely replaced by a bronze-brown ; the discal series of red spots are edged with black, and the outer edgings to the sub-terminal series of white lunules are prominently and broadly black.[1]
