35 PAPILIONID.E. PIERIN.^.. — DELIAS. 



sub-median nervure, is snboval aiul dusted with black scales ; the outer part of 

 the disc is traversed by a narrow undulate crimson line, divided by the black 

 veins ; this line extends from the costa at about one-third from the apex to 

 the sub-median nervure, and is situate about the middle of the black outer area 

 following the contour of the wings, but at its lower end it is further from 

 the outer margin ; above the upper median nervule to the apex the crimson line 

 is bordered outwardly by a diffused silvery white streak. The inner margin is 

 irrorated by yellow scales ; antenns black. 



Hab. Aroa River, British New Guinea, at an altitude of 8,000 feet.

The transposition by me of this species from the Genus Tachyris, in which it is placed by 

 Herr Ribbe, to the Genus Delias, renders a change of its specific name necessary, a " Delias 

 Weiskei" having been already described by Herr Ribbe (vide supra). I have re-named it 

 " Mirifica " as appropriate to this marvellous insect.
