80 On Four new Butterflies from South-icest Madagascar. 



Female. — Ujjjjerside. Anterior wings dusky stramineous, 

 base and costa grey ; apical area broadly dark grey, gradually 

 narrowing along the outer margin down to the posterior 

 angle, the inner edge angulated on the veins ; a large grey 

 spot at the end of the cell ; the discal bar of the male is 

 represented by a grey spot between the two upper median 

 nervules, and another between the lowest median nervule and 

 the submedian ncrvuve rather nearer the base. Posterior 

 wings more yellowish stramineous, all the veins tipped on the 

 margin with large suboval grey spots ; there is an indication 

 of an irmer row of grey spots, represented by several clusters 

 of grey scales. 



Underside. Anterior wings sordid stramineous, brighter at 

 the base and in the apical area, with the large spot at the end 

 of the cell and the two discal spots as on tiie upperside. 

 Posterior wings brighter stramineous ; costa at tiie base 

 orange. 



Expanse of wings 2 inches. 



Hab. Mahobo. 



The female bears a considerable resemblance to B. liliana^ 

 Grose Smith, but the male is quite dilfcrcnt. 



One or both of these, as well as the species next described, 

 may be referable to the genus Pinacojyteryx^ ^Yallengren. 



Belenois mahoho. 



Mule. — Upperside. Both wings lacteous white, with a few 

 grey scales at the base. Anterior wings with apical and 

 outer marginal area grey, as in B. mahella^ but less broadly 

 so ; a minute grey spot at the end of the cell ; a cluster of grey 

 scales, forming an indistinct spot on the disk, between the 

 upper and middle median nervules. Posterior wings without 

 any markings. 



Underside resembles maheUa, but the apex of anterior and 

 the whole of the posterior wings is rather browner ; the spot 

 at the end of the cell of anterior wings is very minute. 



Female. — Upperside. Both wings pure white, irrorated witii 

 grey at the base. Anterior wings : apex grey, as in the 

 male, with a minute spot at the end of the cell ; a cluster of 

 grey scales forming a spot, larger and further from the margin 

 than in the male, between the upper and middle median 

 nervules. Posterior wings without any markings or grey 

 scales except at the base. 



Underside. Anterior wings sordid white, pale brownish 

 stramineous at the apex, with the spots at the end of the cell 

 and on the disk as on the upjierside. Posterior wings
