ochreous, then with a broad, narrowing white streak, which 

 sends out slight excrescences into the ground-colour before 

 one-half and again at two-thirds, and terminates in a point 

 shortly before apex ; a pure white inner-marginal streak, 

 commencing in a point at before one-third, gradually widening, 

 and reaching from tornus to M 2 at termen ; base somewhat 

 suffused with light silvery, merging into the white costal 

 streak ; an indistinct grey postmedian line as in claudiaria, 

 Schaus, Tr. Am. Ent. Soc. xxvii. p. 165 (not mentioned in 

 Schaus's description), no trace of an antemedian ; fringe 

 greyish red-brown, at extreme apex and towards tornus on 

 inner margin ochreous. Mind wing reddish brown, some- 

 what more purple-tinted than fore wing ; extreme base red- 

 brown, brighter than in fore wing ; a subbasal white stripe, 

 broadening on costa, followed by an ochreous shade except 

 at inner margin ; a vague diffuse band of iridescent silvery 

 scales from SC a beyond middle of wing to inner margin near 

 tornus, curved in its posterior part ; s onie similar scales along 

 inner margin ; a rather large, round, embossed metallic spot 

 of about the same size, colour, and position as in pepita, 

 Dogu. Ann. Soc. Ent. Belg. xl. p. 144 {(Jphthalmophora) , 

 and a second, smaller spot on termen, also as in that species ; 

 terminal line bright silvery, broader and less sharply defined 

 in posterior half, accompanied proximally by a very narrow 

 ochreous line in anterior half ; anterior half of fringe very 

 pale ochreous, posterior deep dull ochreous ; inner-marginal 

 fold and fringe dirty white. Underside dirty white, fore 

 wing with a rather broad terminal band and the fringe 

 smoky.

Similar to O. claudiaria, Schaus [=fosteri, Warr. Nov. 

 Zool. xvi. p. 99, nov. syn.), from Brazil and Paraguay, but 

 differing in somewhat darker colour, the hind wing more 

 purplish (in claudiaria more ochreous), in having somewhat 

 broader costal and much broader inner-marginal white 

 streaks, larger embossed spot on hind wing, and a second 

 spot at termen, and in having the marginal silvery line 

 terminal, whereas in claudiaria it is subterminal. Moreover, 

 the second segment of abdomen is only very narrowly and 

 indistinctly pale, while in claudiaria there is a very distinct 

 pure white transverse bar.

S ? . 30-32 mm. — Head, thorax, abdomen, and wings
