 towards apex and anal angle washed with red ; two continu- 

 ous nearly approximated dark brown lines, the inner one of 

 the primaries incurved towards the costal margin, the outer

 on the inner side a triangular hyaline spot ; a dark brown

14. Duomitus ligneus^ sp. n. 



Pale sandy brown ; wings sparsely mottled with black, 

 most densely on the external area of primaries, where they 

 form a series of ill-defined hastate streaks between the veins, 

 increasing in length towards the inner margin, and interrupted 

 by white circular spots more or less obscured by grey reticu- 

 lations ; several indistinct black internervular streaks between 

 the subcostal branches ; costal margin spotted with black :
