upper augle of cell ; Sth subcostal nervule close to the angle, 

 curved upwards at first, so as nearly to touch the common stem of 

 the other 4, then running nearly parallel to upper radial into the 

 hind margin below the apex ; common stem of the rest rising at 

 I of cell ; 1st leaving it just beyond the point where the Sth is 

 approximated to it ; 2nd and 3rd both shortly before apex ; 4th 

 running into apex itself. Hind wings, $ : with the discocellular 

 vertical, costal and subcostal approximating at a point not far 

 from base, the subcostal branches forking as usual from upper 

 angle of cell, the lower subcostal reaching the hind margin at |- 

 from interior angle ; 1st median nervule only a little before lower 

 angle of cell, 2nd and 3rd together from the angle ; radial from 

 the centre of the discocellular. c? : With the cell much broadened, 

 and somewhat distorted ; 2nd subcostal curving strongly down- 

 wards away from the 1st, and reacliing the hind margin well 

 below the centre ; discocellular running obliquely inwards from 

 the curvature of the 2nd subcostal; 1st median just before, 2ud 

 and 3rd from the lower end of cell ; radial just above the origin of 

 the last 2 ; inner margin fringed thickly with long hairs. 



Type, Dysethia hicommata, sp. n. 



The difference in the neuration of the hind wings of the sexes 

 is somewhat analogous to that which occurs in the Larentiad 

 genera Anaitis, &c. 



Dysethia bicommata, sp. n. (Plate XXXII. fig. 1.) 



cJ 2 ' I'ore wings deep fuscous-brown, sprinkled, especially 

 towards costa and base, with pale hlac scales ; lines blackish : — 1st 

 at I runs obliquely outwards, and reaches the inner margin not 

 much before its centre, forming a strongly marked angulation on the 

 submedian ; 2nd a little before the middle, forms an irregularly 

 triangular mark on costa only, nearly touching the large oval 

 blackish discal spot ; 3rd at | forms a curved, blackish, outwardly 

 pointed costal spot, then a sinuous, pale-edged line to near the 

 anal angle; submarginal Ime denticulate, formed of pale lilac 

 scales, most distinct towards the costa, where it is preceded by a 

 dark costal patch ; fringe fuscous-brown ; basal line of fringes and 

 all the nervules beyond the middle of the wing yellowish. Hind 

 wings of 2 ^s the fore wings, with a dark brown submarginal 

 curved line ; of d" dull greyish ochreous, with a diffuse dark shade 

 in place of the line which is visible in the 2 . Head, thorax, and 

 abdomen concolorous with ground-colour of fore wings. Underside 

 dull fuscous, with the exterior liue and discal spots only darker ; 

 in the c? , the underside is rather strongly tinged with tawny, 

 especially along the costa ; the ? , if fresh, would probably show 

 the same tint ; in the S , owing to the displacement of the radial, 

 the dark discal spot, which is very diffuse, is situate almost at the 

 lower angle of the cell. 



Expanse of wings, $ 38 millim., c? 34 millim.

It is worthy of observation that the pale lilac scales, which are
