Wings, (ippersu/e. Forewing : resembling in the grey tone U. sericcipennis, 



but more fawn-colour, outer area not so dark, wing broader, the hinder angle less 

 produced ; both subbasal patches very large, the costal one nearly 7 mm. long, the 

 proximal submedian line not marked, the distal one more distal than in the allied 

 species, the upper portion of the line rather heavy, at right angles to the costal 

 margin, running from the margin to the lower cell-angle, then continued as a very 

 thin line in a curve to vein M-, which it reaches 3 ram. from the discal line ; tlie 

 latter begins as a cloud at the costal margin, is very thin between R' and internal 

 margin, consisting of faint lunules, the line crosses M- 13 mm. from the edge of 

 the wing, standing here a little nearer the cell than outer margin ; the following- 

 lines indistinct, except oblique costal portions ; submarginal line as in sericeipenxis. 

 Hindwing : basal area up to median band heavily washed with mummy brown. 



Umlerside less mottled with blackish brown than in senceipennis, the snb- 

 margiual blackish brown line of the forewing well marked, the grey scaling outside 

 it not reacliing vein M-. 



?. Vaginal plate rather strongly chitinised (PI. XV. f. ;">) ; orifice not 

 large, its anterior edge not much raised, simple ; po.^tvaginal part of plate large, 

 rounded. The two halves of the eighth tergite strongly rounded, the sinus rather 

 wide and deep. 



Length of forewing : ? , 60 mm. ; breadth "J.i mm. 



The last autennal joint of the single known individual of this insect is luucli 

 longer than in any other specimen of Ox'/ainhuhfX we have seen.
