32 CYMATOPHORJD^.— LEUCANIID^. 



second line forms the outer margin 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- 

 shaped 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 tegulse 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 clash ; 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. 



Darjiling (Atkinson and Lidderdate) . 



The rounded character of the markings on the primaries gives this species more nearly 

 the character of the better known species of Thyatira than that of T. fiorens, which reminds 

 one of Prospulla.
