Show 1891.] MrCRO-LEPIDOPTERA OF THE WEST INDIES. 531 Exp. al. 11 millim. Hab. West Indies-St. Vincent (windward side, 2 specimens, Smith). Type, 3 2- XYL OR YGTINJE. GLYPHIDOCERA, gen. n. (y~hwpts = a notch, (ceoas=a horn.) Type, 3 2 Glyphidocera audax, Wlsm. Antenncc : male, slightly serrate, deeply notched on the upperside a little beyond the basal joint; female, simple, having no notch, but the outer end of the basal joint is somewhat enlarged. Maxillary palpi obsolete. Labial palpi long, recurved, clothed with closely appressed scales ; apical joint acuminate, rather more than half the length of the second joint. Head densely clothed above ; face smooth. Thorax smooth. Fore wings narrow, elongate, depressed, and rounded at the apex, slightly arched at the extreme base of the costa, costal and dorsal margins parallel, anal angle rounded. Neuration : 11 veins ; 2 and 3 from a recurved common stem ; 7 closely approximate to 8 at base, running to apical margin below apex, 8 to costal margin. Hind wings more than twice the breadth of the fore wings, slightly rounded at the apex, outer margin evenly rounded to the abdominal angle; cilia sbort and even. Neuration : 8 veins ; 3 and 4 from a short common stem ; 5 straight, moderately remote from origin of 34-4 ; 6 and 7 from a common stem ; 8 joined to upper margin of cell by a cross vein. Legs: posterior pair with unequal spurs; tibiae moderately clothed. It seems at present impossible to arrive at the affinities of this genus; the notched antennae would suggest Blastobasis, Z., and Holcocera, Clem., from which it differs widely in neuration and the shape of the hind wings. Its neuration conforms to the Xyloryctida?, Meyr., from which it is separated by the absence of a tuft of hairlike scales near the base of the hind wings; nevertheless it will be excusable perhaps to place it in this family, at least provisionally. GLYPHIDOCERA AUDAX, sp. n. (Plate XLI. fig. 8, a-c.) Antenna? subochreous. Palpi fawn-brown, dusted with fuscous. Head and thorax fawn-brown. Fore wings dull fawn-brown, densely irrorated with fuscous scales throughout; with an elongate transverse fuscous spot before the middle, of which the lower extremity touches the fold ; a smaller fuscous spot at the end of the cell; a few fuscous scales about the apical margin indicate the extremities of the veins; cilia pale fawn-brown, with a darker line along their middle. |
