( 322 ) 



Hindwing : darker ; with a blackish shade close to base, a diffuse blackish 

 central shade, marked by white dashes on veins, following the black cell-spot, and 

 developing into a large black patch on inner margin ; a zigzag black snbmarginal 

 marking from anal angle. 



Underside duller, paler, the hindwing with a faint bluish-white flush, both 

 black-speckled ; a brown marginal border on both wings, in the forewing with the 

 black zigzag anal streak shown, and a black mark on costa before the slightly 

 paler apex ; cell-spots black. 



Face brown ; vertex whitish ; shoulders, patagia, and thorax very pale 

 ochreous ; abdomen brown, with the basal and anal segments of dorsum blackish 

 marked. 



Expanse of wings : 44 mm. 



1 c?, 1 ¥ from La Oroya, E. Inambari, Carabaya, Peru, 3100 ft., September 

 1904, dry season (Ockenden). 



c? with outer margin of both wings curved ; ¥ with it strongly angled at 

 middle, and the apex of forewing acutely produced, as in Folia albipuncta Warr. 



331. Polla nigriseriata spec. nov. 



Forewing : greyish brown, thickly sprinkled with black striae ; lines very 

 obscure ; first oblique inwards, to one-fifth of inner margin, with a dark mark 

 on costa at one-third, below which it is angled ; a brown streak at two-thirds, 

 oblique outwards, angled on vein 7, then oblique inwards to middle of inner 

 margin ; an inwardly oblique white streak from costa just before apex emitting 

 fine white lines along veins 7, 8, 9, and marked by small white dots on veins 

 6 and 5, below which two divergent series of black spots on veins run to inner 

 margin, the outer one to anal angle, those of the inner row sometimes minutely 

 tipped with white ; cell-spot black ; fringe concolorous. 



Hindwing: with the two series of black spots and an antemedian dark line 

 from inner margin, all obsolete above vein 4 ; cell-spot black ; costa whitish grey. 



Underside paler ; outer line marked by bluish-white vein-dashes on forewing, 

 and becoming distinctly luuulate-dentate on hindwing; marginal area beyond it 

 browner with traces of a snbmarginal series of white dashes in hindwing, less 

 distinct on forewing, but connected at anal angle by a black zigzag line ; cell-spots 

 black. 



Head, thorax, and abdomen concolorous with wings ; shoulders and base of 

 patagia pale ochreous ; legs mottled fuscous and whitish. 



Expanse of wings : 38 mm. 



2 <$<$ from Sapucay, Paraguay, November 1903, and October 1904 (Foster). 

 Evidently allied to F. toraria Schaus from Brazil ; perhaps a dark form of it. 



332. Polla olivacea spec. nov. 



Forewing : dull olive-green on a dark iron-grey ground, which shows up in 

 proportion as the olive scales are abraded ; costa finely streaked with black ; inner 

 line visible only as an iron-grey oblique streak from one-half of inner margin to the 

 origin of vein 2 ; two white costal streaks before apex, meeting on vein 7 ; the 

 inner, representing outer line, marked with dark at costa, angled on vein 7, and 

 produced to middle of inner margin as a sinuous row of white vein-dots, which are 

 plainer above middle ; fringe olive-green ; cell-spot black.
