Zethera mum, Felder, Wien. ent. Monatschr. v. p. 301. n. 16 (1861) ; 

 Keise der Nov. Lep. iii. pi. liv. figs. 6, 7 (1867). 



c? 2 . Pasananca valley, Mindanao, February 1875. 



Z. aganippe of Felder, figured on the same plate (fig. 3), 

 appears to me to be the female of Z. mum. The sexes in 

 this genus are very dissimilar. 



20. Sevanda Duponchelii. 



Satyrus Duponchelii, Guerin, Voy. Coquille, pi. xvii. fig. 3 (1829).

Although Guerin quotes this himself as a synonym of 

 Boisduval's Mycalesis dorycus, and gives the locality Dorey 

 m the letterpress, his figure does not agree with that species, 

 but with the Aru form, which differs in the obsolete character 

 of the orange patch on the primaries, in the absence of the 

 blackish border to the secondaries above, and in having the 

 primaries below ochreous instead of smoky brown ; the secon- 

 daries of the Aru form also only show four ocelli on the under 

 surface, the second of 8. dorycus not being present. In 

 Moore's paper on the Lepidoptera referred to Mycalesis (Tr. 

 Ent. Soc. 1880, pp. 155-177), I see that Aru is given as one 

 of the localities for S. Duponchelii) this habitat was doubtless 

 obtained from Hewitson's paper in the 'Journal of the Linnean 

 Society/ viii. p. 145 (1865), where the following additional 

 localities are also given : — a Waigiou, New Guinea, Mysol." 

 Felder also gives New Guinea as the locality for his Mycalesis 

 gctulia, quoted by Moore as a synonym. 



^n examination of Hewitson's series seems clearly to 

 show that S. Duponchelii, 8. dorycus, and 8. getulia are 

 distinct although closely allied species (or local races, if that 

 name be considered preferable), which could readily be distin- 

 guished if one possessed a fair series from each locality, but 

 (as in many other instances) which look like slight varieties 

 when single specimens from each locality are alone retained. 

 Hewitson only possessed a single female from Dorey; and we 

 possess three males from that locality. These are ail uniform 

 in the dark border to the secondaries above, the pale under
