538 L. de Niceville — Description of Neptis praslini. [No. 2 



it is of great width anteriorly, rapidly narrowing to the abdo- 

 minal margin, which it does not quite reach ; the anterior end of 

 the discal band in N. nausicaa reaching much closer to the outer margin 

 than in N. lactaria. On the underside of the hindwing there is a single 

 subcostal streak, in N. lactaria this streak is much shorter, with an 

 additional round spot placed posterior to it close to the base of the 

 wing ; and in N. lactaria there is a marginal series of eight linear spots 

 which are entirely wanting in N. nausicaa. 



I am indebted to Mr. Henley Grose Smith for the gift of the speci- 

 mens described. 



This species mimics Tellervo zoilus, Fabricius. The specimen 

 figured is a male.

 obliquely-placed subapical spots ; two much larger, the upper the larger 

 of the two, almost conjoined discal spots divided by the second median 

 nervule ; a submarginal series of six small spots, the series broken in 

 the middle ; a barely traceable marginal series of dots ; an elongated 

 bluish-white streak on the middle of the sutural area. Hindwing with 

 the middle occupied by an oval patch consisting of five portions ; a sub- 

 marginal series of six linear spots. Underside, forewing with a pale 

 streak defining the basal half of the subcostal nervure ; all the spots on 

 the disc more prominent than on the upperside, particularly the mar- 

 ginal linear series. Hindwing with the oval quinquepartite discal area 

 as ou the upperside ; anterior to which there is a small round basal 

 spot, and a lengthened pale subcostal streak ; the submarginal spots
