Species of Indo- Malay an Lepidoptera. 181 



brown discal angular band, tlie commencement of a dupli- 

 cate submarginal band at the anal angle ; double lunular 

 black lines close to the outer margin of both wing?, with 

 pale centre ; cilia brown, with ochreous spots at the end of 

 veins 5, 6, and 7 on the hind wing, more pronounced in the 

 females than in the males ; abdomen with an ochreous tip in 

 the male. Underside : both wings with the inner half grey, 

 the outer half blackish brown, with a medial outwardly 

 curved black band, broadly edged with white on both sides ; 

 a white patch on the hinder angle of both wings, four white 

 dots on the costa of the fore wing near the apex ; marginal 

 white dots on both wings and some whitish suffusion on the 

 upper margin of the hind wing. 



Expanse of wings, $ 2j 3 , ? 2^ inches. 



Hub. Kina Balu, N. Borneo. 



The larger markings somewhat resemble those on S. tene- 

 brosa, Butler, from Sikkim ; the markings of a great many 

 forms of this genus have a wonderful resemblance to each 

 other. I have examples from Kina Balu and from Nanchuan 

 in China that cannot be distinguished from S. umbrosa, 

 Butler, from Assam, and a female example from Kina Balu 

 that is absolutely identical with females of S. picta, Butler, 

 from Japan; it seems highly improbable that non-migrating 

 insects, so widely separated, can be of the same species ; 

 the inspection of their genitalia is necessary to decide the 

 matter.

Hypocala toana, nov. 



c? . Upperside : fore wing grey sparsely irrorated with 

 brown atoms, most thickly in the middle where the atoms 

 are large ; outer margin with black dots : hind wing pale 

 greyish yellow, with large black outer border occupying more 

 than a third of the wing, marginal edge and cilia white. 

 Underside uniform greyish yellow, a blackish lunular mark 

 at the end of each cell, with white centre, larger on the fore 

 wings than on the hind wings; a blackish discal band across 

 the fore wing; a broad marginal, similarly coloured band 

 on the hind wing, with white outer edging and white cilia; 

 head, body, and legs concolorous with the wings. On the
