to the wliitisli ones of upper surface and on the hind wing a 

 triangular white patch from tornus about to E,^ 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. 



Ivory Coast, type and another j Cooniassie, 3 ? ? in GolJ. 

 Brit. Mas. 



Characterized by the strongly incurved postraedian line and 

 the length of the dark marks distally to it. 



29. Milionia anisochri/sa, sp. n. 

 (PI. Vll. fig. 7.) 



? . — 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 icing 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 ratlier elongate ; black, with a few yellow 

 scales in places and a small patch of the same colour between 

 R^ and M^, about halfway between cell and termen. 



Fore wnig 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 j\F ; the distal 

 black border is rather broad on apical region, with slio-ht 

 indentations of the ground-colour, narrower (scarcely 2 mm ) 

 from W to behind M^. 



Biak, Schouten Islands, June 1914 (^A. C. and F. Pratt). 



The upper surface rather recalls hicolorata, VVarr. (Nov. 

 Zool. iii. p. 398), but the under shows afSnity with tricolor, 

 Warr. (Nov. Zool. iii. p. 130). I cannot see that the group 

 {Pseudeusemia, Weym., in Lep. Xiepelt. i. p. 10) is separable 

 structurally from Milionia.
