 This again is a wide-ranging species.

8. ZlZERA GAIKA. 



LyccBna gaiha, Trimen, Trans. Ent. Soc. ser. 3, vol. i. p. 403 

 (1862).

This is a common and widely distributed African and Arabian 

 insect.

5 , slightly broken ; very deep in colour.

 Madagascar, and the Island of Johanna ; it varies somewhat on

 of the markings below.

Pontia chjnamene, Klug, Symb. Pbys. pi. vi. figs. 15, 16 (1829).

12. Teracolus phisadia. 



Pieris pMsadia, Godart, Enc. Meth. ix. p. 132 (1819). 



Three males, two of them much shattered. 



An interesting fact respecting this species is that, whereas all 

 the Arabian males show a wet phase of under-surface and the 

 Arabian females a dry phase, the same species from Northern 

 Africa sometimes shows a dry phase in the male ; 1 have not seen 

 enough African examples to enable me to say whether a wet phase 

 of female ever occurs.
