one at end of third median, the other at end of submedian 

 fold ; a slight indentation below apex, which is prominent 

 and bluntly rounded ; legs long and slender. Antennae 

 lamellate, the edges of the joints slightly projecting, long, 

 but curled round towards tips. Labial palpi upcurved in 

 front of face ; second joint with long hairs beneath, terminal 

 acute ; maxillary palpi distinct ; tongue present. Cell of 

 fore wings quite two thirds, first median some distance before' 

 end ; second and third medians and lower radial close to- 

 gether from lower end of cell ; upper radial well below the 

 upper end of cell ; last subcostal from the end ; second, third, 

 and fourth stalked from shortly before end ; first subcostal 

 free. Hind wings : second subcostal from the angle of cell ; 

 first anastomosing with costal till just before hind margin ; 

 discocellular very oblique ; radial and third median on longish 

 stalk ; second median from lower angle, first considerably 

 before angle. Scaling smooth and glossy, with few and in-

Eristena murinalis^ sp. n. 



Fore wings pale mouse-colour, in the male with no 

 markings but the slightly darker cell-spot and an ill-defined 

 exterior line just beyond it ; fringe concolorous, with a fine 

 pale basal line, followed by a thick darker one. Hind wings 

 whitish for two thirds ; like fore wings in the marginal area, 

 beyond a curved, slightly wavy, subterminal line. In the 

 female the fore wings are shorter, slightly tinged with 

 ochreous ; the exterior line is distinct, being edged with 

 paler, and forming a slight sinus outward in the middle, and 

 the discal dot is preceded by an indistinct vertical darker 

 shade ; the hind wings are paler, with discal dot and sub- 

 terminal line more distinct. Head, thorax, and abdomen all 

 concolorous, paler in female than in male. Underside glossy, 

 with hardly any markings ; the fore wings darker than the 

 hind ones.
