Show 1891.] MICRO-LEPIDOPTERA OF THE WEST INDIES. 507 along the veins and margin, especially towards the abdominal margin; cilia cinereous, with a pale line along their base. Abdomen brownish cinereous. Legs pale cinereous ; hind tarsal joints faintly speckled. Exp. al. 13-14 millim. Hab. West Indies-St. Vincent (windward side, 3 specimens, Smith) ; Dominica (one specimen given m e by Mr. II. Druce). Type, 3 $ . This species agrees in structure with ejectana, Wkr., an Australian species. I may remark that veins 6 and 7 of the hind wings, although perhaps not actually from a common stem, have so much the appearance of being so that a mistake might easily arise. They are almost anastomosed along their basal half, having the appearance of a double vein grooved along its under surface rather than of two separate veins. I find the same structure prevailing in the Australian species. HELIGMOCERA, gen. n. (e\tyjuos = a sinuosity ; Kepcts=a horn.) Type, 6* Heligmocera calvifrons, sp. nov. (Plate XLI. fig, 5, a-Antenna? (3) stout, strongly pubescent beneath; basal joint thickened, beyond which is a strong sinuosity on the upper side, extending over several joints. Palpi not thickly clothed, with the basal joint unusually long, slightly upturned ; second joint long, projecting forward ; apical joint fully half the length of the second, slightly depressed. Haustellum very short. Head clothed above; face flattened, almost excavate between the eyes, and sloping back to the base of the antennae. Thorax not tufted. Fore wings elongate, costa slightly arched, 3 with a strong costal fold containing a thick mat of hairs; apical margin oblique, slightly concave, apex slightly produced, anal angle rounded. Neuration: 12 veins ; 3 and 4 closely approximate throughout, curved upwards nearly to middle of apical margin ; 5 straight, arising very near 4, about the lower angle of cell and ending on the middle of the apical margin in close proximity to 4; 6 bent down towards 5 on margin; 7 and 8 from a common stem, 7 bent down towards 6, 8 to costal margin above apex; 9 arising from upper angle of cell close to origin of 7 + 8. Hind wings broader than the fore wings, with a broadly lanceolate apex, abdominal angle strongly developed and heavily fringed, especially at the base. Neuration : 8 veins; 3 and 4 from a long common stem ; 5 bent over to origin of 3 + 4 ; 6 and 7 from a common stem. Legs: hind tibiae densely clothed with projecting scales above the spurs. |
