ON NEW AND LITTLE-KNOWN BUTTERFLIES. 457 



Habitat : Sikkim ; Bhutan ; Naga Hills ( Ekoes) ; Upper Chind- 

 wiu, Burma ( Watson) ; Palawan, one of the Philippine Isles (Stau- 

 dinger). I have specimens of this species only from Sikkim but have no 

 doubt that Messrs. Elwes and Watson have recorded it correctly from 

 Upper Assam and Upper Burma. It is^ I think, rather doubtful, 

 however, that it occurs in Palawan as Dr. Staudinger says it does. It 

 is seasonally dimorphic as usual. 



22. Symbrenthia Silana, de Niceville. 



S, silana, de Mcdville. Journ, A, S. B,, vol. liv, pt. 2, p. 117, pi. II, fig, 9, 

 male (18)^5) ; id., Moore, Lep. Ind., vol. iv, p. 121, pi. cccxxv, figs. 2, 2ar, 

 fnale, wet-season form, ; 2b, male, dry-season form (1899). 



Habitat : Sikkim ; Bhutan. A rare species with a very limited 

 range, and slightly seasonally dimorphic. 



23. Symbrenthia Hypatia, Wallace. 



Lasgona hypatia, Wallace, Trans. Ent. Soc. Lend., 1869, pp. 344, 345, n. 3 ; 

 Symhrentliia hypatia, Distant, Rhop. Malay., p. 432, n. 2, pi. xlii, fig. 6, male 

 (1886) ; id., Fruhstorfer, Berl. Ent. Zeitsch., vol. xxxviii, p, 3^6 (1893) ; 

 idem, id., Stat. Eut, Zeit., vol. Iv, p. 125, pi. iii, fig. 4, male (1894) ; id., de 

 Niceville and Martin, Journ. A. S. B., vol. Ixiv, pt. 2, p. 488, p. 239 (1895) ; 

 id., Moore, Lep. Ind., vol. iv, p. 122 (1899) ; S. hypatia, var. chersonesia 

 Fruhstorfer, Berl. Ent. Zeitsch,, vol, xxxviii, p. 366 (1893) ; S. hypatia, \z,v. 

 hippocrene Staudinger, Iris, vol. ix, p. 232, pi. v, fig. 3, male (1897). 



Habitat ; Malay Peninsula ; Sumatra ; Java ; Borneo. 



I GODCur with Dr. Moore in placing the var. [chersonesia of 

 Fruhstorfer from the Malay Peninsula, and the var.] hippocrene of 

 Staudinger, from Kiua Balu Mountain and Brunei in North- Western 

 Borneo as synonyms of S. hypatia, Wallace, from Java. S. hypatia is 

 a rare species, and appears to be confined to mountainous districts, Dr. 

 Moore, has described its female from Sumatra. 



■ 24, Symbrenthia Intricata, Fruhstorfer. 



S. intricata, Fruhstorfer, Ent. Nach., vol. xxiii, p. 61 (1897) ; idem, id., 

 Berl. Ent. Zeitsch., vol. xli, p. 312 (1897). 



Habitat : Toli-Toli, North Celebes. I have not seen this species. 

 25. Symbrenthia Hippalus, Felder. 



Laogena hippalus, Felder, Reise Novara, Lep., vol, iii, p. 396, n. 587, pi. li, 

 figs, 9, 10, TOaZe(1867), 



Habitat : Halmaheira (Felder) ; Mount Tondano, N.-E. Celebes 

 (colU de JSicevilW). 



I possess a single male of this species ; the female has not been described. 

 It is a very remarkable species, there is nothing else like it in the genus.
