to the whitish ones of upper surface and on the hind wing a 
triangular white patch from tornus about to R? and some ill- 
defined white apical shading ; termen as above ; the white at 
base of fringe broader on posterior half of fore wing and 
most of hind wing, the dark spots at vein-ends strengthened.

Characterized by the strongly incurved postmedian line and 
the length of the dark marks distally to it. 
29. Milionia anisochrysa, sp. n. 
(Pl. VIL. fig. 7.) 
2 .—46 mm. 
Face black. Palpus short, blackish. Vertex blackish. 
brown; occiput black. Collar, front of thorax, and fore 
coxa yellowish white. Thorax and abdomen above black, the 
latter with some yellow scales at the ends of the segments; 
sides of abdomen bright yellow, venter much paler and duller. 
Fore wing rather long and narrow ; SC*~? coincident, free ; 
black, with a transverse oblique white patch of 1-2 mm, 
width from SC#~* (and basal part of SC’ after its separation) 
to M’, constricted in middle, its proximal edge being nearly 
straight, its distal projecting at R', sinuate inward between 
this and R?. 
Hind wing rather elongate; black, with a few yellow 
scales in places and a small patch of the same colour between 
Ri? and M}, about halfway between cell and termen. 
Fore wing beneath as above, the white band slightly 
widened. Hind wing beneath yellow, with a black border 
and_an interrupted black band joining the border at costa and 
towards tornus, Just entering the anterior corner of the cell, 
suddenly narrowed at cell-fold by a projection of the proximal 
ground-colour, widening again gradually from M! ; the distal 
black border is rather broad on apical region, with slight 
indentations of the ground-colour, narrower (scarcely 2 mm.) 
from R? to behind M!. 
Biak, Schouten Islands, June 1914 (A. C. and F. Prait). 
The upper surface rather recalls bicolorata, Warr. (Nov. 
Zoo). iii. p. 398), but the under shows affinity with trzcolor, 
Warr. (Nov. Zool. iii. p. 130). I cannot see that the group 
(Pseudeusemia, Weym., in Lep. Niepelt. i. p. 10) is separable 
structurally from Milionza.
