36 LEriDOPTERA. 



and iieclv-riclge white ; thorax smooth, mixed pale brown 

 and white ; abdotnen short, rather thicic, asby-wliite with a 

 series of minute brown tufts down the dorsal ridge, and on 

 each side of these a line of brown clouds ; lateral and anal 

 tufts small and compressed. Fore wings long, the apical 

 portion much produced; costa nearly straight; apex bluntly 

 rounded ; hind margin very long and oblique, gently curved ; 

 dorsal margin rather short, also curved ; colour white shaded 

 with light brown ; all the markings so extremely oblique as 

 to be with difficulty allotted in the usual formula — near the 

 base are two, closely following, pale brown lines lying 

 obliquely outwards but merging into a brown cloud on the 

 costa; first line parallel with these, double, and forming a 

 brown stripe, arising on the dorsal margin as two black 

 streaks, again blackened on the median nervure, and a little 

 so where bent up to the costa ; beyond is another brown 

 stripe, almost parallel, of the same width, and blackened on 

 the nervures ; and beyond this a third, not far from the hind 

 margin, each of these making a more or less distinct bend 

 back at the subcostal nervure to meet dashes of brown from 

 the costa ; the second line scmm to be represented by the white 

 inter-stripe between the second and third last mentioned, 

 but it cuts through the third and throws a white dash into 

 the apex of the wing ; hind margin clouded with brown, in 

 which is the subterminal line, white and edged inwardly 

 by smoky-black clouding ; cilia white or greyish-white, 

 spotted with smoky-black. Hind wings rather elongated, 

 rounded behind, white faintly clouded with grey but having 

 beyond the middle a clear white transverse stripe, distinct in 

 the grey clouding, or even preceded and followed by dark 

 grey-brown shades ; cilia white, spotted with brown-black. 

 Female very similar, but often having the markings and 

 hind wings darker. 



Underside of the fore wings light umbreous, with the 

 nervures darker ; some costal dashes, a very oblique straight 

 stripe beyond the middle, and the hind margin nearly white ;
