Show 382 MR. W. WARREN ON NEW GENERA AND [Apr. 18, a common stem from the upper angle of cell, the 5th starting halfway ; the 2nd, 3rd, and 4th, one after the other, in the order named. Hind wings with the cell broad and the discocellular angulated; tbe subcostal nervules on a common stem. Type, G. schistacea, Moore (Anticlea). GAGITODES OLIVACEA, sp. n. (Plate XXX. fig. 6.) 2 • Fore wings olive, suffused with darker; basal patch small, velvety black, finely edged with white, not reaching the inner margin; central fascia interrupted in the middle; costal portion shaped something like an hour-glass, velvety black, edged with white; lower portion short, of the ground-colour, toad-stool shaped, edged with whitish; submarginal line sinuous, irregular, white, twice interrupted ; fringes olive, with darker dots at end of veins. Hind wings and fringes dull whitish, with black dots at end of veins. Head, thorax, and abdomen olive. Underside ashy, with the basal half of both wings darker. Expanse of wings 28 millim. Hab. Sikkim. [A pair of this distinct species are all I have seen. I collected them on Sundukpho at about 12,000 feet in July.-H. J. E.] EURYPEPLODES, gen. nov. Fore wings ample, with costa curved throughout, and with an indistinct bulge about l from the base ; apex blunt; hind margin evenly and strongly curved. Hind wings broad, rounded; hind margin slightly elbowed below the middle. Antenna?, $ , simple, slender ; forehead decidedly projecting; tongue present; palpi as in Iramha, long, rostriform, loosely scaled beneath. Neuration :- Fore wing: cell half the length of the wing ; discocellular curved and oblique; 1st median nervule at -|; 2nd shortly before end; 3rd from the end ; the median nervure between the 2nd and 3rd inclined upwards ; lower radial from a little above the centre of the discocellular ; areole simple but large ; upper radial from just above its lower angle ; 5th subcostal from just below its upper angle; 1st subcostal also just before the upper end; 4th from the upper angle ; 2nd and 3rd out of 4th at \ and J- respectively. Hind wings : cell unusually broad, somewhat contorted; costal anastomosing with subcostal to near the end of cell; 2 subcostals on a common stem; discocellular subangulated ; radial from the angulation ; median nervules as in fore wings. Type, Eurypeplodes irambata, sp. n. The genus seems intermediate between Hydrelia and Eupithecia, having the shape and markings of the former, with the raised cell-spot of the latter, and the palpi of Iramba. I have not seen a 6. EURYPEPLODES IRAMBATA, sp. n. (Plate XXX. fig. 8.) 3. Fore wings pinkish testaceous, with a succession of darker, slightly wavy lines, angulated on the subcostal, and darker thence to the costa ; those forming the edges of the central fascia show as small |
