This species is not in the British-Museum collection ; but fortu- 

 nately the type still exists in the Banksian Collection in the British 

 Museum. Mr. Hewitson, in his criticism upon Mr. "Wallace's paper 

 (Ent. Trans, p. 99, 1868), has given a brief description taken from 

 this type. The nearest allies of the species are the P. Paulina of 

 Cramer and the P. Nysa of Eabricius. Donovan's figure is by no 

 means characteristic.

This species has been compared with P. Cenea, Stoll, Euchloe 

 Cceneos, Hiibner, and Laurion Ccenea, Drury, but proves to be nothing 

 more than a variety of the well-known Thyca from Amboina.
