254 LEPIDOPTERA. 



wings rather small, shining silvery-grey, with black clouding 

 and tranverse lines ; hind wings very similar, but a little 

 paler. Female more silvery-grey. 



Antenna3 of the male simple, rather thick, almost imper- 

 ceptibly ciliated, shining brown-black ; palpi of moderate 

 size, but hidden by abundance of long projecting black hair- 

 scales ; tongue long ; head densely and prominently tufted 

 with black hair-scales ; thorax shining black ; abdomen ' 

 smooth, velvety, black-brown ; anal tuft small. Fore wings 

 narrow ; costa arched throughout ; apex bluntly angulated ; 

 hind margin gently rounded ; dorsal margin almost straight ; 

 colour shining smoky-black, dusted with white ; first line 

 deep black, much indented, and placed in several curves, 

 edged and shaded off inwardly with silvery- white ; second 

 line not very oblique, but deeply angulated inwards just 

 above the dorsal margin, and indented throughout, black, 

 edged and shaded on the outside with white ; the space 

 between these lines forms a darker central baud, and contains 

 the discal spot, which is ovate and deep black ; subterminal 

 line silvery-white, much indented and often obscured ; 

 extreme hind margin dotted with black, and sometimes 

 alternately with silvery-white ; cilia smoky-black, shot with 

 pale grey. Hind wrings rather elongated and narrow, 

 rounded behind, smoky-black ; central spot round, black ; 

 just beyond it is an obscure transverse whitish stripe ; beyond 

 this another, undulating and rather scalloped, partially 

 connected with a third which lies along the hind margin, 

 all being formed of rather scattered white scales ; cilia long, 

 smoky-brown. Female stouter, but with more slender 

 antennge ; the silvery-white shadings and lines of the wings 

 broadened, and much more suffused, so that the ground 

 colour of the fore wings often is almost silvery-white, with 

 only the two lines black ; the hind wings also paler. 



Underside of the fore wings smoky-black to the middle, or 

 even to beyond the discal spot ; in the hind wings to the 

 middle ; this in each case is abruptly cut off, the remaining
