 wings as on the upperside, the costal margin of posterior 

 wings at the base bright orange. 



Expanse of wings 2f inches. 



Nearest to P. antsianaka, Ward, and P. affinis, Mab. 



Mylothris mojungana.

 apex from a little beyond the middle of the costal margin 

 broadly, and thence along the outer margin gradually decreas- 

 ing to the inner angle, black, the inner edge deeply dentate as 

 in nagare, Grose Smith ; the costal margin at the base grey, 

 the base of the wings brightly tinged with orange. Posterior 

 wings pale yellow, the lowest subcostal, the discoidal, and 

 median nervules tipped with black. 



Underside. Anterior wings stramineous, apex broadly ful- 

 vous, the base to the middle of the cell orange. Posterior 

 wings bright fulvous, costal margin, from the base to the 

 middle, orange.

Nearest to M. Lasti, Grose Smith, from Mombasa. 



Acrcea andromba. 



Male. — Upperside. Resembles A. obeira, Hew. (piva, 

 Guenee), but is smaller ; the anterior wings are narrower, and 

 the posterior wings rounder ; the rufous basal colouring on the 

 anterior wings is paler, and extends nearly to the end of the 

 cell and to the posterior angle. On the posterior wings the 

 rufous area extends over nearly all the wings, especially 

 towards the anal angle, where it reaches the margin, the 

 spots at the base and in the irregular row across the disk are 

 comparatively smaller, the dark marginal band is more 

 defined, in which, between the veins and touching the mar- 

 gin, is a row of six nearly round bright rufous spots ; in 

 obeira these spots are only three or four in number, are 

 situate towards the anal angle, and are more elongate in 

 shape. 



On the underside of the posterior wings the marginal row 

 of rufous spots is more distinct than in A. obeira. 



The female is much paler, the coloured area of both wings 

 being stramineous, and extending over nearly the whole 

 of the posterior wings. 



Expanse of wings, £ If, ? 2£ inches.
