On a new Genus of Butterfly from Madagascar. 359 



XLIV. — Description of a Butterfly from Madagascar forming 

 a new Genus, from the Collection of Henley Grose Smith 

 and (by his benevolence) of W. G. Hewitson. By W. C. 

 Hewitson, F.L.S. 



Smerina, n. gen. 



Body of moderate size, half the length of the posterior 

 wing. Anterior wing produced at the apex, slightly sinuated 

 on the outer margin. Posterior wing produced at the anal 

 angle. 



Head large. Eyes hairy. Palpi large, spatulate, twice as 

 long as the head, covered with hair, the last joint minute. 

 Antennae long, distinctly clubbed. 



Anterior wing with the costal nervure half the length of 

 the wing : subcostal with four branches — two before the end 

 of the cell, two near together halfway between the end of the 

 cell and the apex : the cell two fifths the length of the wing', 

 closed in a regular curve ; the first discocellular nervure 

 minute, the second and third of equal length. 



Posterior wing with the cell short, scarcely a third the 

 length of the wing, closed obliquely. 



Fore legs (male) of moderate length, the femur, tibia, and 

 tarsus (which is covered with long hair) of equal length. 



Four hind legs very long : the femur (which is covered 

 with hair) and the tibia of equal length ; the tarsus longer, 

 covered beneath with spines. 



Smerina Vindonissa. 



Upperside. Female ferruginous. Anterior wing with two 

 linear spots in the cell and one at the end of the cell, a large 

 spot from the costal margin beyond its middle, the costal 

 margin, the apex, and outer margin (where it is broad), and 

 three spots near its inner border, all dark brown. Posterior 

 wing crossed beyond the middle by a series of four or five 

 black spots, and by two submarginal undulate bands of the 

 same colour : the outer margin dark brown. 



Underside pale brown. Both wings crossed from the costal 

 margin of the anterior wing, beyond its middle, to the anal 

 angle of the posterior wing by a common narrow dark-brown 

 band, bordered outwardly with silver-lilac: both wings crossed 

 beyond this by a series of brown spots and by two submarginal 

 indistinct bands of the same colour. Anterior wing with two 

 silver spots within the cell : a black line on each side of the 

 discocellular nervures. and a band from the middle of the costal 

 margin, which joins the central band and encloses a pale glossy
