226 J. Wood-Mason and Lionel de Niceville — List of [No. 3, 



in the anterior wing being narrower and externally slightly emarginate 

 (instead of well-rounded), with its outer submarginal series of spots re- 

 duced to small specks, and the three posterior ones of its inner series 

 externally distinctly tridentate ; and in the posterior wing being also 

 apparently somewhat narrower and less rounded externally, with both series 

 of submarginal spots much smaller, — with its two posterior veins margined 

 on both sides with fuscous of a far lighter and duller tint than the rest 

 of the ground, — and with the submedian one of them more prominent with 

 the wing-membrane on each side of it raised into a slight fold and the two 

 light streaks that bound it dirty whitey-brown : the male of this species is, 

 in fact, provided with a distinct, though little -specialized, sexual mark or 

 scent-gland. 



Length of anterior wing, S 1*5, ? 155 ; whence expanse = $ 31, 

 $ 3 2 inches. 



One male and three females, -the latter agreeing exactly with one 

 another, from Great Nicobar. 



D. vulgaris, Butler, from Upper Tenasserim, Malacca, and Borneo, D. 

 eceprompta from Ceylon, D. juventa from Java, and D. nicobarica from the 

 Nicobars appear to us to be only constant geographical varieties of D. similis 

 from Formosa and China. Mr. Butler in describing the first-named species 

 (Ent. Month. Mag., 1874, vol. xi, p. 164) gives 'Nepal, Bengal' as localities 

 for it in addition to Singapur and Borneo. This is probably a mistake ; we 

 have seen no specimen of it from any region further to the west than 

 Upper Tenasserim. 



4. Danais plexippus. 



One male and two females from Nankowri Island ; five males from 

 Kar Nicobar ; also Kamorta (Moore) . Numerous specimens of both sexes 

 from Kamorta and Nankowri {Colonel Cadell). 



5. Danais hegesippus, var. nesippus. 

 D. nesippus, Felder, Yerh. zool.-bot. Gesellsch. Wien, 1862, vol. xii, p. 486, £ ; 

 Beise Novara, Lep., p. 347, S ? • 



Four males and five females from Nankowri Island ; and Great Nicobar 

 (Felder). 



6. EUPL(EA (MACEOPLffiA) phcebus. 



Euploea phcebus, Butler, Proc. Zool. Soc. Lond., 1866, p. 270, <J ? . 



Macroplcea phcebus, Butler, Journ. Linn. Soc. Lond., Zoology, 1878, vol. xiv, p. 292. 

 One very fine male from Kar Nicobar Island agreeing (except in its 

 rather larger size, its expanse being 5*3 inches) exactly with continental 

 specimens from Cherra Punji.
