along the black nervures and along the hind-margin ; the 

 fringes are also black. On tlie under side the wings are yel- 

 lowish-grey, with black nervures. 



This genus, like Mesapia and Baltia^ was originally placed 

 ?n the Equitidce. D. armandi flies among the rocks after 

 the manner of Parnassius^ to which these three genera have 

 been thought to be allied. 



GENUS METAPORIA. 

 Metaporia, Butler, Cist. Ent. i. pp. 38, 51 (1870). 



Front-wings sub-pyriform, second sub-costal nervule not 

 so near end of cell as in Aporia ; upper disco-cellular oblique, 

 nearly as long as lower, which is perpendicular and feebly 

 arched; second and third median branches rather near together. 

 Hind-wings sub-pyriform, the cell broader and less pointed, 

 disco-cellulars of equal length, the upper oblique, the lower 

 less so. Body moderately hairy ; palpi slender, hairy beneath ; 

 antennae with distinct flattened club {Butler). 



This genus contains a number of Indian Butterflies, more 

 or less pale in the cells of the wings, and broadly dark along 

 all the nervures. The type is M. agathon (Gray), from North 

 India, a Butterfly of about three inches in expanse, which 

 might either be described as white, with black spots widely 

 separated by the nervures and a transverse black band beyond 

 the cell ; or black, with the cells and intermediate spaces be- 

 neath white, and a double series of long spots beyond.
