582 DESCRIPTIONS OF INDIAN MICRO-LEPIDOPTERA. BY E. MeYRICK, B.A., F.R.S., F.Z.S. X. EUCOSMID^E. Epibacira, n. g. Antennae in ^ minutely ciliated. Palpi moderately long, porrected, second joint dilated with rough scales above and beneath, terminal joint moderately long, slender. Thorax smooth. Forewings with 7 and 8 stalked. Hindwings with 3 and 4 separate, approximated at base, 5 closely approximated to 4 at base, 6 and 7 stalked. Closely allied to Bactra, especially to the first two species desciibed hereafter from which it only differs essentially by the stalking of veins 7 and 8 of forewings. Epibactra arenosa. n. sp. ^. 17-22 mm. Head, palpi, thorax, and abdomen whicish-ochreous, palpi sometimes partially tinged or spiinkled with fuscous. Forewings elongate, rather narrow, posteriorly somewhat dilated, costa gently arched, apex round-pointed, termen sinuate, little oblique ; whitish-ochreous, partially tinged or mixed with brownish-ochreous, and with more or less pronounced tiaces of scattered stri-gulae of fine blackish -fuscous irroiation ; costa maiked thioughout with short oblique strigulae of fine blackish-irroration ; some undefined biownish-ochieous suffusion towards costa on posterior half, sometimes mixed with fuscous, and an undefined similar spot in disc at ^ : cilia pale ochreous, tips infuscated on termen. Hindwings fuscous-whitish ; cilia whitish-ochreous, with an indistinct fuscous line near base. Maskeliya, Ceylon, in June and October (Pole) ; three specimens. Bactra, Stph. The species of this genus present considerable difficulties, being similar and variable, and close study is necessary to discriminate them. Ten are desciibed here, but I do not find that any Indian specimens can be referred to the European lanceolana, Hb.,or the African siccellu. Walk. The foim of wing and length of palpi are the most reliable characters, and must be carefully observed, but although the markings are usually vague and inconstant, they do notwith-standing present a distinct type in each species. In addition to those described I possess others of which the material is insufficient for desciiption ; and I shall be glad if collectors will pay attention to these obscure insects, and when possible collect good series of them from the same locality, to show the range of variation ; any particulars of habit Avould also be useful. Possibly all may feed on species of rush (Ju7icus). Bactra faderata, n, sp, (J. 20-22 mm. Head, thorax, and abdomen whitish-ochreous. Palpi 4,
