anteciliary line aloue being of the dull black ground-colour ; the 

 posterior edge of the blackish area bearing four rounded deep black 

 spots ; the two black spots on the outer margin as on the upperside. 

 Falpi above, thorax and abdomen above black, but the latter tipped with 

 white. Palpi beneath, thorax, legs, and abdomen beneath pure white. 



Near to T. lavata, Butler, from Malacca [Butler)^ and Perak {Dis- 

 tant)^ knov/n to me by figures and descriptions only, from which T. toba 

 differs in having two or three discal as well as the subapical dots 

 in the forewing ; the hindwing differs in the white area on both upper- 

 and undersides being spotted with black, in 1\ lavata it is immaculate; 

 the hindwing also appears to be conspicuously narrower and produced 

 anally. It is also near to T. gracilentus, Weymer,* from New Britain 

 ( Weymer), but that species has the white area on the upperside of the 

 hindwing at least twice as large as in T. toba^ and the anteciliary line 

 is developed into a broad band which includes the two black marginal 

 spots of T. toba. The shape of the wings will also distinguish T. toba 

 from the common and widely-distributed T. atticuSj Fabricius, the 

 hindwing in especial being much longer and narrower. 



Described from several examples in the collection of Hofrath 

 Dr. L. Martin and my own taken in March, April, and October. 



33. KORUTHAIALOS KERALA, n. sp., PI. T, Fig. 48, $. 



Habitat : Perak, Malay PeninsiTla ; Battak Mountains, N.-E. 

 Sumatra. 



Expanse : $, P75 to 1'90 ; 9, 1-75 to 2-15 inches. 



Desoeiption : Male. Upperside, both loings shining fuscous. 

 Foreioing with a broad oblique discal orange fascia exactly as in Kerana 

 armatus, Druce, that is to say, the band is about twice as long as it is 

 broad, and it does not quite reach the costa, the outer margin at the 

 anal angle, or the inner margin; but it differs slightly in form from the 

 band in that species as its inner edge anteriorly is obliquely cut off 

 instead of being continued straight to the costa. Hindiving unmarked. 

 Underside, both loings paler than on the upperside, of a more sooty 

 brown. Foreioing has the discal band rather broader than on the up- 

 perside, reaching the inner margin ; it is paler moreover throughout, 

 especially so posteriorly. Hindwing immaculate. Cilia fuscous 

 throughout. Antennce, black, the apex of the dub paler beneath.
