530 LORD WALSINGHAM ON THE [XoV. 17, 



Maxillary palpi obsolete. 



Labial palpi short, projecting, scarcely recurved ; apical joint 

 lon»ei- than the second joint. 



Haustellum moderate. 



Head smooth. 



Thorax stout. 



Fore wings elongate, subovate, costa somewhat arched beyond the 



middle, apex rounded, apical margin oblique, rounded. Neuration : 



12 veins, all separate ; 7 and 8 closely approximate at their base ; 



•9 remote from 8; 10 very near 9, and approaching it even more 



closely where it reaches the costal margin. 



Hind wings trapezoidal, of even width throughout, dorsal margin 

 slightly concave, apex rounded, apical margin convex. Neuration : 

 8 veins ; 3 and 4 from a point; 6 and 7 separate, but approximate 

 towards their base. 



Abdomen somewhat stout. 



Legs smooth, spurs unequal. 



This genus differs from the ordinary forms of the Glyphipterygince 

 in having smooth (not hairy) legs, and in the form of the hind 

 wings, which is trapezoidal, but in other respects it appears to fall 

 into the neighbourhood of Aelocosma, Meyr. 



Trapeziophora gemmula, sp. n. (Plate XLI. fig. 7, a-5.) 



Antennce fuscous. 



Palpi whitish, doubly barred with black across the second joint 

 and with a hlack longitudinal line throughout the length of the 

 apical joint beneath. 



Head purplish fuscous. 



Thorax greyish fuscous. 



Fore wings greyish fuscous at the base, blending into bright 

 purple on the apical half of the wing ; the basal half irrorated with 

 small whitish shining dots, which run in a series of confused lines, 

 radiating outwards from the base to the middle of the wing ; a few 

 similar dots, but of a rather yellower colour, are visible about the 

 middle of the bright purple apical half of the wing ; upon this outer 

 half are four distinct shining iridescent metallic bauds, with a lilac 

 or green reflexion — the first commencing on the costa, just beyond 

 the middle qf the wing, is widened and diff'used downwards, but not 

 reaching to the lower margin of the cell ; the second is shorter, with 

 a slightly oblique outward direction, and is more remote from tlie 

 first than are the two beyond it from itself or each other ; the third 

 band, commencing on the costa and curving obliquely outwards, is 

 recurved below the middle to the anal angle ; beyond it a short 

 fourth band crosses before the apex from the costa to the middle of 

 the apical margin ; cilia greyish about the apex, tending to purplish 

 grey about the anal angle. Underside unicolorous purplish fuscous. 



Hind wings brown ; cilia greyish brown. Underside greyish 

 brown, with three bright metallic transverse streaks near the apex. 



Abdomen greyish fuscous; dingy whitish beneath. 



Legs banded with black and white.
