1684.] LKPIDOPTERA FROM ADEN. 493 



IIopfFer probably only had a female befora him when he wrote 

 his diagnosis of this form. The under surface of the secondaries and 

 apex of primaries in the male is of a pearly greenish tint, the dusky 

 atoms being confined almost entirely to the costal border of the 

 secondaries ; the female even is scarcely ochraceous on the uuder- 

 surface ; I should rather describe the secondaries as sericeous greenish 

 yellow, sparsely reticulated with greyish squamosa striae ; the usual 

 purplish discocellular marking with white centre and creamy-white 

 spot attached to its outer edge. 



There is no doubt that the local forms named by Hopffer E. 

 mosamhicensis, capensis, and arabica are permanent, and should be 

 kept separate.

Aden, 3rd, 23rd, and 26th February, 1884, and 2nd March, 1883. 



All the specimens are much darker on the under surface than 

 those from Sind and Beloochistan, the apex of the primaries having 

 the blackish ground-colour of the remainder of the wing, and the 

 secondaries having the ground-colour dark greyish olivaceous instead 

 of pale yellowish. As the Aden form may prove to be distinct 

 (and is at any rate more w'orthy of a name than many of the forms 

 recognized on the Continent), I propose to call it var. adenensis.
