 quite one-third of inner margin, preceded there by a purplish shade ; outer luuulate- 

 dentate, from the third costal sjiot, ontcurved above aud incurved from 4 to middle 

 of inner margin, where it approaches inner line ; a large purplish black ear- 

 shaped cell-spot beneath the second costal spot; submarginal' shade cloudy 

 imrplish, darker and ontcurved beyond cell and between 1 and 3, the marginal area 

 at apex and between 3 and 4 pale bluish white ; black marginal luunles ; fringe

 middle of hindwing pale bluish wliite, the baud showing slightly on inner margin 

 of forewiug ; lines and cell-s])ots indistinctly deeper purple ; inner margin of 

 hindwing more broadly yellow.

In Xoc. Zool. x. p. 350 mention was made of 3 ? ? from the Upper Aroa 

 River (which were there referred to satarutaria Wlk.), in which the usual green 

 upperside of that species had acquired the slaty coloration of the underside ; the 

 last mentioned of the three certainly, and the other two probably, should be referred 

 to the present species. I am also inclined to keep H. caesia, from Fergusson and Ron 

 Islands, distinct from the New Guinea species.
