interspace, touching the submedian nervure. Hindwing with three 

 conjugated spots in the middle of the disc, the middle one nearest the 

 outer margin, the innermost one the largest. Underside, both wings 

 fuscous, thickly irrorated or overlaid with ochreous scales. Forewing 

 with the inner margin extending broadly on to the disc fuscous ; the 

 spots as on the upperside, except that the one in the submedian inter- 

 space is larger with diffused edges. Hindwing as on the uppersi'de. 

 Cilia pale ochreous-f uscous throughout. Antennae black, the tip of the 

 club, excluding the whip-like tip, shining white beneath. Female. 

 Upperside, both wings fuscous, lacking altogether the vinous gloss of 

 the male, the base irrorated with ochreous scales. Otherwise as in the 

 male. 



Near to Isma bononia, Hewitson, described from Singapore, in 

 my collection from Perak and N.-E. Sumatra, but that species has 

 typically no spots in the discoidal cell of the forewing. Also near to 

 Isma inarime, de Niceville, from Perak, N.-E. Sumatra, Java, and Pulo 

 Laut, but the spots on the hindwing are smaller and differently shaped ; 

 they are also more numerous in that species. Also near to Isma feralia, 

 Hewitson, described from Java, occurs also in N.-E. Sumatra and Pulo 

 Laut, but in that species all the spots are pure translucent white instead 

 of lustrous pale ochreous, and the spot in the submedian interspace 

 of the forewing is quadrate and extends right across the space instead 

 of being round and touching the submedian nervure, reaching only to 

 the middle of the interspace. Also probably near to Isma obscura, Dis- 

 tant, from Singapore, but that species has one spot only in the discoidal 

 cell of the forewing, and none on the hindw'ing on the disc. Also near to 

 Isma submacidata, Staudinger, described from Palawan in the Philippine 

 Isles, but in my collection from Karwar, North Kanara, Bombay Presi- 

 dency; Cachar in Assam ; Daunat Range, Tenasserim, Burma; Perak in 

 the Malay Peninsula; N.-E. Sumatra; and Pulo Laut, but that species 

 has no translucent spots whatever on the hindwing. The only other 

 species of the genus known to me is Isma corissa, Hewitson = Isoteinon 

 indrasana, Elwes and de Niceville, from Burma, N.-E. Sumatra, Java, 

 and Pulo Laut, which is altogether a differently-coloured and marked 

 species from the rest of the genus.* 



Described from three males from Tounghoo and one from the Daunat 

 Range, both in Burma, and two females from Java. The type is from 

 Burma. I have not received both sexes from one locality, and it may be 

 that the Javan is distinct from the Burmese species, the former having 



# See footnote on p. 571 ante. None of the species here mentioned of the genus 

 Isma have male secondary sexual characters, and are therefore probably generically 

 distinct.
