more prominent than above ; with an additional marginal linear series 

 of eight spots. 



Apart from other characters, the oval white patch confined to the 

 middle of the hind wing will at once serve to distinguish this species 

 from N. lactaria, Butler, and N. vausicaa, de Niceville. 



Described from a single example which I have received from Mr. 

 Henley Grose Smith. 



This species mimics Tellervo sequicinctus, Godman and Salvin, or 

 T. hiero, Godman and Salvin. 



5. Neptis dorcas, Grose Smith. 



N. dorcas, Grose Smith, Nov. Zool., vol. i, p. 354, n. 115 (1894) ; id., Grose 

 Smith and Kirby, Rhop. Ex., pi. Neptis i, figs. 7, 8 (1895). 



Habitat : Biak Island, N.-W. New Guinea {Grose Smith). 



This species is quite distinct from all those previously mentioned. 

 It may be known from N. lactaria, Butler, as identified by me, by 

 the extreme irregularity of the outer edge of the discal white band of 

 the hindwing, that portion of the band lying in the discoidal interspace 

 being outwardly greatly lengthened and projecting far beyond the line 

 of the other portions. The sex of the two specimens described is not 

 stated, but they are probably females. 



In describing this species Mr. Henley Grose Smith refers twice to 

 the " white oval patch " of the hindwing in N. praslini from New 

 Ireland. From this I gather that Mr. Grose Smith identifies N. praslini 

 with the species I have described as N. nemeus, though my specimen 

 is from a different island, and may be distinct from the New Ireland 

 form, and that he calls the species I identify as JV". lactaria — JV. papua. 

 I have given my reasons above for preferring to apply Boisduval's name 

 to the species which Dr. Staudinger has figured, and M. Oberthur has 

 described as JV. papua, and which the latter writer says is probably the 

 true JV. praslini. 



This species mimics Tellervo evages, Godman and Salvin,* or 

 T. mysoriensis,f Staudinger.
