249. Callipseustes trisecta spec. nov. 



Forewing : pale greenish ochreous (perhaps olive-green when fresh) with 

 darker olive striatums ; a dark olive central fascia, occupying on costa the middle 

 third of the wing, its inner edge oblique and nearly straight to beyond middle 

 of inner margin, its outer parallel to inner edge as far as vein 4, there bent 

 nearly at right angles and running vertically to inner margin at three-fourths ; 

 the fascia is finely edged on each side with whitish ; two dark horizontal marks 

 before outer margin on each side of vein 4 ; fringe (worn) greenish. 



Hindwing : pale greenish ochreous, greener in basal area before the dark 

 flexnons outer line ; cell-spot dark grey. 



Underside dingy ochreous speckled with olive, with outer series of dark vein- 

 spots, and a dark cell-spot on each wing, the fascia showing through. 



Head, thorax, and abdomen dull olive, the aual tufts ochreous. 



Expanse of wings : 22 mm.

250. Ischnopteris albipennis ab. obumbrata nov. 



Differs from the type form in having no white scales whatever in forewing ; 

 the basal and marginal areas wholly dull grey-green; the central area rilled with 

 dull red-brown, which tint also extends over the lower half of the marginal area 

 and is sometimes mixed with green. 



In the hindwing the inner margin below median vein and vein 2 is smoky 

 black, and the marginal border thicker and blacker, containing on its inner edge 

 a distinct curved black line ; the veins black in the white area. 



Head, thorax, and abdomen pale green ; anal tuft yellowish. 



Expause of wings : 39 mm. 



2 $ $ from La Oroya, It. Inambari, Peru, 3100 feet, September 1904, dry season 

 (Ockenden). 



Smaller than the type and differing in both wings : it may be a distinct 

 species. 



251. Ischnopteris discolor Warr. S. 



The ? only was described in Nov. Zool., xi. p. 557 ; the c? differs as follows : 

 Forewing : dark mossy green in basal and marginal areas ; central area, except 

 along costa, dark purplish fuscous ; a broad baud before submarginal line diffusely 

 purplish red ; first line from one-fifth of costa to one-third of inner margin, angled 

 outwards on subcostal vein and submedian fold and again close above inner margin, 

 preceded by a line of greenish white scales ; outer line from three-fifths of costa 

 to two-thirds of inner margin, sinuous, oblique outwards and broadly rounded at 

 vein 5, deeply insinuate in submedian interval, and again outwardly rounded on 

 submedian vein, followed by a pale green line, mixed with whitish scales below ; 

 submarginal Hue pale green, forming zigzags at costa, and an upright whitish 

 mark at anal angle, interrupted between ; marginal lunules black ; fringe mossy 

 green ; cell-spot black; before it from middle of costa a thick dark mediau line 

 can be seen, angled outwards on median and approaching outer line on inner 

 margin. 



Hindwing: ochreous, tinged with grey, gradually darkening to outer margin; 

 cell-spot obscure, followed by a dark curved postmedian line, bent in on vein 4 ;
