CYMATOPHOEID^. — LEUCANIID^. 
second line forms the outer Tnargin of a partly white- bordered brassy yellow band; beyond 
this band the inner border is rather broadly yellow, interrupted by the irregular lines, and 
partly edged internally with silvery white ; it expands at its extremity into a large wedge- 
sliaped patch ; costal margin dotted with yellow in the central area ; discoidal spots silvery 
white ; the " reniform " spot, which is oval, is tinted in front with yellow ; a transverse 
yellow spot on costal area just beyond the cell, and a small white spot connected with it at its 
inferior extremity ; a similar but larger apical spot ; two white dots on the first median branch 
between the cell and the cuneiform patch ; three white dots on the veins between the latter 
and the apical patch ; a bifid yellow spot at centre of external border ; a marginal series of 
silvery white lunules ; fringe spotted with white, but with a yellow spot at apex : secondaries 
pale brown, with a broad diffused submarginal band ; fringe greyish, with an olivaceous basal 
line : thorax dark olivaceous, the front of head and tips of tegulae greyish ; abdomen pale 
brown. Under surface whity brown : wings clouded with grey, excepting at the borders, ■which 
are sharply defined and partly macular ; fringe spotted with whitish. Expanse of wings 
43 millim,

Coloration of the preceding species ; but the primaries with two unequal pale yellow 
spots placed obliquely near the base in place of the irregular band, the discoidal spots larger, 
the reniform spot more oblique ; the subcostal spot beyond the cell rounded and with no small 
spot below and connected with it; the apical spot replaced by an oblique dash; the wedge- 
shaped patch at external angle rounded and broken up; the spot at centre of external border 
smaller ; the under surface altogether of a more golden reddish tint, the grey clouding less 
pronounced and the pale borders partly obsolete and altogether less distinct. Expanse of 
wings 40 millim.

The rounded character of the markings on the primaries gives tins species more nearly 
the character of the better known species of Thyatira than that of T. florens, which reminds 
one of Prospalta.

^ . Primaries above extremely like Leucania l-album of Europe, but of a redder colour.
