Descriptions of New Genera and Species. 



DoDONA Eugenes. 



S. Closely allied to D. Egeon (D. & H. Gen. D. L, pi. 69. f. 2); wings 

 of the same shape, and the form of the tail of the hind wings the same. 

 Above dark, blackish bi'own. Fore wing with a narrow line across the 

 middle (touching neither the costa nor the hind margin), a curved 

 streak near the hind angle, and about thirteen small spots pretty 

 equally distributed over the apical half of the wing ; all these marks 

 are whitish except the transverse line and marks near the hind angle, 

 which are slightly tinted with reddish tawny. Hind wings with the 

 outer portion traversed by four indistinct brownish-tawny lines, con- 

 verging from the costa towards the anal angle ; at the apex are two 

 black spots edged with light brown. On the broad, square lobe at 

 the anal angle is a quadrate black spot, a slender tail arising from its 

 outer edge. 

 Beneath, the wings are precisely similar to those of D. Egeon, being 

 tawny brown, with stripes and spots of white, silky and shining on 

 the hind wing and costa of fore wing.

Nepaul and Bhotan. The species seems to have been con- 

 founded hitherto with D. Egeon ; but the very different colour 

 and small dimensions of the stripes and spots of the upper surface 

 well distinguish it. 



Alesa lipara. 



c?. Smaller than A. Priolas; fore wing much shorter, and outer border 

 of hind wing not bowed outwards near the apex as in J. Priolas. 



Above uniform dark purple ; fore wing with scarcely any trace of the 

 pale lines between the nervures towards the apex. Beneath pale 

 brownish gray, much paler than in A. Priolas; nervures of the apical 

 half of the fore wing, and lines between them, dark brown. Hind wing 

 with seven small basal spots, and two narrow transverse lines, brown ; 

 a submarginal row of seven oblong black spots. 



Expanse 1" 6'". 



Hab. Forests of the river Tapajos, Amazons. 



Alesa Thelydrias. 



c?. Much smaller than A. Priolas, and quite distinct in the colours 

 of the male, which resemble those of the females of this genus. 

 Shape of the wings similar, but outer border of hind wing not ex- 

 panded. 



Above brownish tawny. Fore wing with the nervures and lines between 

 them (those terminating on the outer border much thickened towards 

 their terminations), and three short belts across the basal half, dark 

 brown. Hind wing with four transverse belts, the outer margin, and 

 fringe dark brown ; besides which the submarginal row of black oval
