 Mr. Meyrick gives the following description of the insect : — 



"Male, 31-41 mm.; Female, 48 mm. 



" Head, antenna?, thorax and abdomen, fuscous or ochreous 

 "fuscous. 



" Forewings sub-oblong, posteriorly somewhat dilated, 

 " costa slightly arched, apex rounded, hindmargin 

 "rounded obliquely, continuously with inner margin 

 " ochreous, ochreous brown, slaty-grey, or dark fuscous ; 

 " generally more or less distinctly marbled with 

 " irregular paler or whitish markings, including 

 "rounded darker spots, sometimes marked with 

 " blackish, but these markings are sometimes wholly 

 " confused or obsolete ; a pale oblique mark from 

 "inner margin near base, margined on each side with 

 " blackish, is generally conspicuous, but sometimes 

 " obsolete ; cilia with basal half ochreous brown, 

 " terminal half white, shai'ply barred with dark 

 " fuscous. 



" Hindwings rather dai'k fuscous ; costa in male suffused 

 " with whitish ochreous or yellow ochreous, cilia as in 

 " forewings. 



" A very variable moth, but the basal mark is a good 

 " characteristic. 



" Posterior tibia? in the male have long curved tufts of 



" hair, rising from above near base, and lying along 



" abdomen." 



The perfect insect appears from tlie middle of September to
