! blackish spots on head, one at apex of thoracic projection, and a row 
1 on each side of abdomen, about half-way between middle and lateral 
margin. 
Described from two specimens (which yielded a and a $ of Porthaon), 
brought from Delagoa Bay by Mrs. Moiiteiro in July 1886. The butterflies 
I did not emerge till the following December, and were both dwarfs. Other 
pupae of this species and of P. Colonna, Ward, which were taken on to Eng- 
' land by Mrs. Monteiro, appear to have come out very satisfactorily in the 
j Insect House at the Zoological Society's Gardens. 
j This butterfly was originally described by Hewitson from Zambesian speci- 
• mens of the $ . Mr. ViMilav {Aiin. and Mag. Nat. Hist., 4th Ser., xix. pp. 458 
and 460, 1877) mentions that many specimens of it and the allied P. NyasscB 
were contained in a collection made at Lake ISTyassa. It appears to occur 
extra-tropically only at Delagoa Bay, where Mrs. Monteiro informs me it is 
common.
