 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).
