Vertex, collar, shoulders, patagia, thorax and basal segments of abdomen fiery 

 orange ; face and palpi deep ferrnginons ; abdomen cinereous. 



Expanse of wings : 39 mm. 



2 ? ? from Sauto Domingo, Carabaya, S.E. Peru, 6500 ft., January and 

 October 1902, dry season (Ockeuden). 



In the second ? the speckling and blotches forming the lines are blackish 

 instead of vinous, like the cell-spot. 



Very much like Ooiopt'da iiiterriipta Warr. {Petelia) from Brazil, witli which 

 I have hitherto confused it, but the undersides are quite different ; in iuternipta the 

 forewiug beneath has a subijuadrate dark apical patch. 



49. Oenoptila subfasciata spec. nov. 



Poyeidiiij : dull fulvous, striated, not speckled, with blackish; the lines diifuse, 

 vinous, and as in siobcon/'usa the inner and outer lines marked by blackish spots on 

 veins ; the position of the lines is the same as in that species, but the median shade 

 is closer to the cell-spot and nearly vertical throughout ; cell-spot black aud large ; 

 a blackish blotch on submarginal line below middle. 



tliiidwing : with the outer lines marked, and the cell-spot distinct and black. 



Underside yellowish straw-colour, almost without speckling ; cell-spots black 

 and large ; a submarginal vinous fascia with its centre blackish. 



Head, thorax, and abdomen dull greyish fulvous ; the abdomen with anal 

 segments and laterally grey 



Expanse of wings : 39 mm. 



1 ? from Santo Domingo, Carabaya, S.E. Peru, 05U0 ft., December 1902, wet 

 season (Ockeuden). 



The difference in the underside will distinguish this species at once from both 

 suhconfusa and interrupta Warr.

 black costal streak ; the basal area, the cell and space below, and the marginal area 

 above vein 5 brick-red ; first line brown close to base, vertical ; second line well 

 before middle, reddish brown, vertical to below median vein, then slightly curved 

 outwards to inner margin before middle, closely followed by the black cell-spot ; 

 outer line purplish black from three-fourths of inner margin, hardly concave out- 

 wards, curving just before reaching the black costal streak aud running through it 

 into apex ; below costal streak at apex the hindmargia is pale grey inwardly edged 

 by two white luuules ; fringe reddish grey with pale base, chequered white below 

 apex and above vein .5. 



Ilindwing : without lines ; cell-spot minute, snow-white in a diffuse brownish 

 shade from before middle of costa, preceded aud followed by a brick-red tint in
