 of that species. Ferruginous-brown. Wings with numerous trans- 

 verse undulating dark lines, as in i. Xylia. Fore winijs with

 less elongated; a more distinct diff'erence is observable in the sub- 

 marginal lunules, which are less undulating and more slender than 

 those of L. Xylia. Fore wings with a pale elongated costal 

 subapical patch. Length of the body 14 lines; of the wings
