formed by two lumellae being curved towards eacb other and togetlier prudnc-ed 

 distad, this j)rocess reseinbliug that of japonica. Peuis-sheath (PI. XXX. f. 12) 

 wider than in the allied species, ventrally chitinised to end, armed with a short 

 stont ventral hook and an obliqnely truncate dorsal process which is irregularly 

 notched. 



?. Vayinal area similar to that of Uturatu.

158. Oxyambulyx bima spec, nov (PI. IX. f. \, 6). 



i. Unknown. 



? . Body as in ? of 0. maculi/era, less grey above, dorsal line of abdomen 

 Very distinct ; foretibia spinose at end. 



Wings, upperside. Forewing : resembling in the grey tone 0. serict'ipennis, 



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

 produced; both snbbasal 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 BP, which it reaches 3 mm. from the discal line ; the 

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

 margin, consisting of faint Innules, 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 sericeipennis. 

 Hindwing : basal area up to median band heavily washed wifh mummy hrown. 



Umlerside less mottled with blackish brown than in sei-iceipeimis, the sub- 

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

 it not reaching vein M-. 



?. Vaginal plate rather strongly chitinised (PI. XV. f. 5); orifice not 

 large, its anterior edge not much raised, simple ; postvagiual 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 2o mm. 



The last antennal joint of the single known individual of this insect is much 

 longer than in any other s|iecimen of Oj:i/ii)nhi(li/.r we have seen.
