154 LLOYDS NATURAL HISTORY. 



with whitish. The spot towards the hinder angle of the fore- 

 wings is absent, and the hind-wings are less varied with yellow 

 beneath, and consequently greener. 



The larva is dull blue, yellowish on the sides, and dotted 

 with black. The head is green, spotted with yellow. It feeds 

 on wild mignonette {Reseda luted) and allied plant?. The pupa 

 is at first greenish, but afterwards grey. 



GENUS MESAriA. 



Mesapia, Gray, LiF.t X.epid. Ins. Brit. Mus. i. p. 92 (1856); 

 Schatz, Exot. Schmett. ii. p. 59 (1886); Kirby, Entomo- 

 logist, xxvii. p. loi (1894). 



Here I propose to insert some very aberrant mountain 

 genera from the Himalayas and Central Asia, about which 

 but little is known at present. Mesapia was for some time 

 supposed to be one of the Equitidce allied to Paniassms ; 

 but Schatz referred it provisionally to the Piei'idce ; and an 

 examination of the essential characters proves it to possess 

 bifid claws, and an internal nervure on the hind-wings. 

 Mesapia resembles the genera Aporia and Metaporia in neura- 

 tion, but the density of the scaling, and the hairy fringes of the 

 wings will distinguish it from the former ; and the long hairs 

 at the base of the wings, the very long club of the antennce, 

 and the peculiarities of neuration will amply separate it from 

 both. I reprint here my description of the genus and species 

 in full. " Palpi long, rather pointed ; antennae long, moderately 

 stout, with a large but gradually formed pyriform club. Body 

 and base of wings clothed with very long slender hairs ; fringes 

 with shorter hairs ; claws of front tarsi distinctly bifid ; wings 

 short, rounded, densely scaled, the fore-wings very broad, sub- 

 triangular ; costal nervure about two-thirds of the length of the 

 wing ; sub-costal nervure four-branched, the first branch emitted
