 TWO NEW SATURNIIDAE. 



By THE HON. WALTER ROTHSCHILD, Pii.D. 



1. Dysdaemonia fosteri spec. nov. 



? . Body cream-colour ; antenna, head, palpns and legs chestnut. 



Wings, upperskle, cream-colour, olivaceous green in distal area, basal area 



feebly washed with green. Forewing : lines and bands green ; a straight line 



from costal to inner margin at base of M-, obtusely angulate at SM- ; a shadowy 

 band outside this line ; two transparent spots at cross-veins, the upper one small, 

 both with green proximal border; a band from costal to inner margin, touching 

 second transparent spot, slightly curving proximad between R' and SM-, sharply 

 defined proximally, gradually shading off distally ; a line between this band and 

 distal margin as in horeas, but a little more curved, brown behind ; hinder angle 



of wing more rounded than in boreas. Hindwing : transparent spot encircled 



with green ; a minute green dot at upper angle of cell ; two lines on disc as in 

 boreas, both obtusely angulate, but the angle of the first line more obtuse than 

 the angle of the second; first line green, broad, gradually shading off distally, 

 widened to a band behind, second line green iu front, brown behind ; outside the 

 second line a brown band irrorated with grey from tail backwards, as in boreas. 



Underside cream-colour, washed with green ; two lines on disc of each wing, 

 both faint.

2. Bunaea macrothyris spec. nov. 



?. Body hair-brown, thorax and abdomen densely irrorated or washed with 

 ochraceous, anterior part of mesonotum, collar, forecoxa and head almost uniformly 

 brown, collar edged with ochraceous ; antenna russet. 



Wings, iipperside, hair-brown, densely irrorated with ochraceous. Forewing : 



basal area bordered by a blackish hair-brown line angulate-sinuate upon M and 

 again at SM- ; along this line a broad white band gradually shading off distally, 

 the white scaling extending at costal margin to submargiual line ; a large trans- 

 parent spot, rounded distally, straight proximall.v, lO mm. long, thinly edged 

 with black, this ring followed by a broad red ring which is widened to a half- 

 cresceut proximally, bordered externally by a pinkish white line which is regularly 

 elliptical iu shape, being broader proximally than distally ; distally of this spot 

 a broad blackish brown line from costal to inner margin, very distinct within the 

 white costal area, becoming faint farther back, evenly curving costad in front, 

 slightly angulate between M- and SM- ; a second blackish brown line parallel 

 to distal margiu from costal edge to II-, being hardly vestigial I'arther baok^ 



8 mm. from distal margin at 11'. Hindwing : base washed with ochraceous ; 



an autcmediau line white, widening behind ; a white line parallel to distal margin, 

 1 1 mm. distant from margin, edged with blackish brown on distal side ; area 

 between the two white lines without ochraceous irroration ; distal marginal area
