Show 530 LORD WALSINGHAM ON THE [Nov. 17, Maxillary palpi obsolete. Labial palpi short, projecting, scarcely recurved ; apical joint longer 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-b.) Antenna? fuscous. Palpi whitish, doubly barred with black across the second joint and with a black 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 bands, with a lilac or green reflexion-the first commencing on the costa, just beyond the middle of the wing, is widened and diffused 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 the 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 bandeVl with black and white. |
