forewing and from the breadth of the marginal border, referable to fulvicomosa. 

 One of them, indeed, is identical with the S, except that it, of course, lacks the hair- 

 clad lobe and silvery washing of the hindwing ; the other, though exactly like 

 the first beneath, shows the dark marginal border of upper side mnch broader, 

 especially in the hindwing, where it extends uniformly from apex to anal angle ; 

 and the three series of pale yellow spots are here coalescent into lines and tinged 

 with grey, and the white ground-colour is striated with grey. I take this to 

 be merely a dark form. 



100. Ophthalmophora ? bimaculata spec. nov. 



Forewing : jmrplish fuscous, with triangular yellow blotches just beyond 

 middle on costa and inner margin, their apices pointing outwards ; fringe 

 concolorous. 



Hindwing : with a lustrous metallic submarginal line from anal angle, where 

 it is very faint, curving round from costa to base of veins 0, 7, preceded on costa 

 by a large dull orange blotch, containing a lustrous spot on costa and limited 

 towards base by a diffuse line of metallic scales running to one-third of inner 

 margin ; the narrow marginal area beyond the curved lustrous line is also dull 

 orange ; the fringe grey ; between veins 6 and 7 a small embossed metallic spot 

 on a black ground in a yellow ring ; above vein 4 touching the lustrous line another 

 embossed spot of silvery scales mixed with black ; below vein 4 the wing is dusted 

 with paler, and a few metallic scales. 



Underside dull grey-brown, the yellow blotches of forewing and the orange 

 blotch on costa of hindwing showing faintly. 



Head, thorax, and abdomen concolorous with wings ; abdomen below and 

 pectus whitish. 



Expanse of wings : 26 mm.

 as the marginal area, dull fulvous; around metallic eye between veins 6 and 7, 

 with fine yellow orbit and black pupil containing an embossed violet spot ; a 

 smaller similar spot before submarginal line above vein 4 : fringe brown. 



Underside of forewing purple-brown, with base and inner margin whitish ; of 

 hindwing white, with margin and fringe purple-brown.
