with creamy buff at base and within the cell, where this 
colour edges the discoidal spots); secondaries shining 
pale brownish, with broad greyish brown external border ; 
fringe with a slender basal yellowish line, a broad central 
dark brown stripe, and white tips; thorax dark grey; 
vertex of head and tips of palpi whitish ; collar occupied 
in front by two large semicircular dull rose-red patches, 
and edged behind with pale grey ; abdomen sericeous- 
erey, blackish towards the anus; anal fringe above 
tipped with testaceous ; under surface pale bronzy brown ; 
wings with a spot at the end of the cell, and a rather 
broad discal band, crossed by pale nervures, blackish 
brown, not very pronounced, but limited internally by a 
slender arched blackish line; a marginal series of black 
lunules ; anterior tarsi black, banded with buff; expanse 
of wings, 1 inch 6 lines. 
Male, Tokei (Fenton); female, Yokohama (Jonas). 
The female I formerly believed to be a well-marked 
variety of X. sodalis, notwithstanding the very dissimilar 
character of the under surface. 
Var. (analogous to combusta type of X. rurea): wings 
above sericeous pale laky brown, with the two usual 
dentated blackish lnes and a purplish brown zigzag 
stripe between them ; a widely bisinuated dusky-bordered 
pale line limiting the external border, which is greyish ; 
orbicular spot oblique; two white dots immediately 
above it upon the subcostal vein; reniform spot varied 
with snow-white and black; several ill-defined zigzag 
lines upon the basal area ; secondaries and under surface 
considerably paler than in the typical form; expanse of 
wings, 1 inch 83 lines. 
Tokei (Fenton). 
Now that we possess both sexes of this species, as 
well as the usual variety, it is impossible to regard it as 
other than a well-defined distinct species.

General aspect and coloration of X. conspicillaris and
