223. Hymenornima densata spec. nov. 



Forming : whitish entirely suffused with dark fuscous and speckled with 

 darker; Hues thick and black ; first from one-fourth of costa outcurved above, then 

 inwards to one-sixth of inner margin, preceded by a thick broken shade; outer 

 line from two-thirds of costa to middle of inner margin, angled inwards below costa, 

 then outcurved to vein 2, not dentate, forming a deep inward sinus across 

 submediau interval ; median shade obscure, parallel to outer line, passing just 

 beyond the black cell-spot ; the outer line is followed by a thick dark shade much 

 mixed with ferruginous; submarginal line sharply luunlate, pale, white just below 

 vein 4, where it is preceded by a black blotch; all the lunules filled up with 

 blackish, over which are sprinkled pale scales; externally the lunules arc joined by 

 black dashes with the black marginal lunules, between which the veins are marked 

 with ferruginous ; fringe pale at base, mottled heavily with dark. 



Hindwing: with basal half whiter, containing a thick black basal mark, a 

 straight autemedian black line, and cell-spot; outer half as in forewing. 



Underside dull dark grey, with median and outer lines marked strongly with 

 black and thickened on veins, the outer nearly straight, not corresponding with the 

 line above ; marginal area of forewing darker, and with a still darker middle shade ; 

 hindwing with the shade just marked; cell-spots black. 



Head and thorax dark like forewing; abdomen paler, but much mottled with 

 blackish on dorsum, and with a black ring near base. 



Expanse of wings : 32—35 mm. 



1 S from La Oroya, II. Inambari, Pern, 3100 ft., September 1904, dry season 

 (Ockenden) type ; 1 <S from Pozuzo, Huauuco, Peru, 800 — 1U00 m. (Hoffmanns). 



Near extersaria Warr. and rufata Warr., darker than either, with no distinct 

 pale patch at middle of outer margin ; the outer line not dentate ; fovea 

 inconspicuous. 



224. Iridopsis grisescens ab. superscripts nov. 



Forewing : pearl-grey, without speckling or suffusiou, and in consequence with 

 all the lines distinct and not obscured as in the typical form ; the two arms of basal 

 line uniting on inner margin ; the median line also double, the two arms forming 

 a darker fascia across wing, the space between them being tinged with fuscous ; 

 a distinct olive-tawny shade beyond outer line, which is present, though much 

 obscured, in the type ; submarginal line indistinct, but followed by a darker shade, 

 which beyond cell is blackish and joined inwardly by two black streaks above and 

 below vein .5 with outer line ; marginal spots large and black ; fringe grey. 



Hindwing : still paler, the basal half whitish; all the lines black and distinct; 

 cell-spot large .and crescent-shaped, black. 



Underside as in the type. 



Expanse of wings : 40 mm. 



1 S from Huancabamba, Cerro de Pasco, Peru, 0000—10,000 ft. (Bdttger), 

 3 other typical c?<? from the same locality, and 1 ¥ from Limbani, Peru, are 

 all of about the same size, and therefore larger than the type which came from 

 (Juito; but a second ? from Limbani, paler than the rest, agrees in size with 

 the type.
