Lepidoptera, by F. A. Heron. 103 



forms the type of a new species, characterized as follows, and 

 called after my friend J. M. C. Austin : — 



Castalius Austini^ sp. n. 



Antennae. Shaft black-brown above, semi-ringed with 

 white below ; club below is of much redder brown. 



Head. Forehead cream-white scaled. Eyes rich deep 

 brown and hairy. 



Palpi dark brown-black ; the second joint creamy scaled 

 below. 



Colour. — Thorax2cn^ abdomen dark brown-black below, with 

 occasionally lighter pubescence of greenish iridescence ; below 

 cream-white, tiie last joints of the abdomen marked off by 

 three creamy scalings at the sides as well. 



Legs dark brown, with cream-white scalings above ; but 

 only the fore legs were retained in this specimen. 



Expanse of wings 28 millim., greatest breadth of fore wing 

 7 millim. ; length of hind wing 9, breadth 6^ millim. ; length 

 of thorax 2^, abdomen 5i millim. 



Wings. Above : brown-black, crossed from the centre of 

 the disk of the fore wing to the inner margin of the hind 

 wings, about one third from the base, by a cream- white band 

 running in the direction of a line from apex of fore wing to 

 centre of its inner margin ; on the fore wing its breadth is 

 about one fifth of the length of inner margin, but expands at 

 the end of the discoidal cell to nearly twice that width, 

 touching vein 6 above, and is slightly cut into by a dark 

 mark which bounds the discoidal cell ; on the hind wings 

 the inner margin of the band is in a straight line with that of 

 the fore wings, but the band as a whole is slightly broader, 

 its width by the discoidal cell being almost half as much as 

 its breadth elsewhere. 



The cilia are of the same colour as the wino;s. 



Below : the same band is apparent ; the costa is dusted 

 with brown, and at its base a patch of almost lemon-coloured 

 scales extends foro millim. in length and 1^ millim. in breadth. 

 There is a submarginal band of creamy white which follows 

 on its inner side the contours of the discal band, and on its 

 outside is parallel to the wing-border ; this band reaches from 

 costa of fore wing to inner margin of hind wing ; the resulting 

 band of dark between the discal and submarginal band 

 averages a little wider than the discal band. 



At the outer margin of the hind wing the dark border 

 tends to split into lunulate spots and to allow a narrow cream- 

 white line to separate it into two portions, the outer forming 

 a mere thread of dark.
