4 LEPIDOPTERA HETEROCERA 
folded. Middle tibize with one apical spur; posterior tibiz with appressed scales, spurs short. Forewings 
clothed with hairs. but with scattered scales on anterior half, ir connected with lower margin of cell by 
bar towards base, 1c weak, appearing to rise from upper end of this bar, parting-vein connected with 
lower margin of cell by bar towards base, 2 and 3 stalked from angle of cell, 4 rising from parting-vein 
(which itself forms cell-wall for a considerable distance). 5 and 6 stalked, 7 to apex, 8 and 9 out of 7, 
10 absent, 11 from rather beyond middle of cell, 12 connected with costa by bar in middle. Hindwings 
more rounded than forewings posteriorly, clothed with hairs; ib connected with rc by bar near base, 
posterior cell-wall normal in form, 2 remote, 3 from angle, 5 and 6 stalked, 8 and 9 out of 7, 1o absent, 
11 from two-thirds of cell, 12 simple. 
Geographical distribution of species. — At present represented by a single Indian species 
from the Khasi Hills.

3. GENUS ERIOCRANIA, ZELLER 
Eriocrania. Zeller, Linn. Ent. Vol. 5, p. 338 (1851). — Type : E. semipurpurella, Stephens. 
Characters. — Head with loose rough hairs. Antenne about one-half, filiform. Labial palpi 
moderate, porrected, hairy beneath. Maxillary palpi long, several-jointed, filiform. folded. Middle tibiae 
with one apical spur; posterior tibize thinly hairy above. Forewings with ra running into i^, forming 
long basal furcation, 1c well defined, connected with lower margin of cell by bar near base, 2 and 3 
approximated, forked parting-vein well-defined, rising out of lower margin of cell near base, terminating 
in 4 and 5, between which transverse vein is absent, no secondary cell, 7 and 8 stalked, 7 to apex, 
9 absent, r1 from before middle without additional branch, r2 without branch. Hindwings under r, 
ovate-lanceolate, cilia three-fourths; neuration as in forewings, but ra out of 15 near base, diverging. 
16 connected with rc by bar near base, 2 and 3 remote. 
Geographical distribution of species. — Confined to the palearctic region; the species are 
similar, difficult of observation, and very liable to be overlooked, appearing in earlv spring. All the 
known larvae: mine blotches in leaves of Beftulaceae.
