One of the most interesting of all the Argj/nnidcs, since 

 it offers the best evidence of the truth of protective assimi- 

 lation ; it supplies the place of A. NicJk in Australia, and, 

 unlike that species, the sexes are alike ; this fact is no

 the model Dcoiais Clirysippus, of which the female D. Nimc 

 is a well known mimic, l)ut which does not occur in Aus- 

 tralia.

Allied to C. Chrysippc, but more dusky above, the basal 

 area sometimes reddish-brown ; the white patch of prima- 

 ries even larger than in C. Cydalima (that is, more than 

 twice as large as in C. Clirydppc) ; secondaries exhibiting 

 an inner discal series of indistinct tawny or occasionally 

 whitey-brown lunate markings ; below, white patch of 

 primaries as above ; spots arranged as in G. Clirysippc, but 

 their zones less blue-tinted : expanse of wings, 3 inches, 5 

 lines.
