2. -NEW FORMS OF RHOPALOCERA. 



By J. J. JOICEY and G. TALBOT. 



PIERIDAE.

1. Mylothris interposita sp. nov. (pi. IX, fig. 1). 



This resembles fiaviana Gr.-Sm., but the colour is sulphur-yellow, 

 as in sulphur ea Auriv., and the apical black of the fore wing is of less 

 extent than in fiaviana, but as in sulphurea. It further resembles this 

 form in the spot at vein 3 on the fore wing being free. The spots in 

 the hind wing are as in fiaviana. 



Habitat. — Bafwasende, April, 1920, one S . 



We have called this a species for convenience. When the Mylothris 

 are better known, such forms as ochracea Auriv., fiaviana Gr.-Sm., 

 sulphurea Auriv., citrina Auriv., primulina Butl., and dimidiata Auriv., 

 will probably be found to be all forms of one species.
