8. Genus: Periilrepasia Btlr. 
Distinguished from Leucodrepana by the antennae being bipectinate in both sexes instead of being 
flat and thickened and densely serrate dentate. Type: P. quinaria Mr. 
P. quinaria Mr. (48 c). Forewing of G white, feebly powdered with grey, in the $ purer; both wings quinaria. 
crossed by undulating grey lines which are more distinct in the $ than in the 8 being powdered with grey; 
palpi, frons, and antennal dents ochreous. North India. 
P. innotata Hmps. (48 d). Both wings hyaline, feebly scaled and without any marking; head, thorax, innotata. 
and abdomen white. Penjab. 
P. verticata Warr. (48 c). Forewing white, semi-transparent, crossed by 5 grey bands, all of which verticata. 
are almost parallel to the margin, on the veins with darker linear markings: 2 proximal ones, 1 distal one, the 
broadest of all, and 2 subterminal ones the distal one of which forms small crescents the dents of which 
touch the grey marginal line; fringes grey; at the cell-end a white crescent, around which there are grey 
scales; costal margin yellow. On the hindwing the three distal lines meet in the anal angle; head, thorax and 
abdomen white, the upper part of the face, vertex, antennae, and forelegs rust-brown. British New Guinea. 
P. inconspicua Leech (48 c and Vol. II, pi. 48 a). Forewing whitish, crossed by numerous undulating, inconspi- 
irregular, grey or greyish-ochreous lines; hindwing similar. Of this species described from China there are 4 cua - 
specimens from the Khasia Hills in the Tring Museum. (Cf. also Vol. II, p. 198.) 
P„ fulvicosta Dudgeon. Quite similar to Leucodrepana furvicosta Hmps. (48 c). Forewing white, costal -fulvicosta. 
margin light yellowish; 5 oblique grey lines, 2 proximal ones, the most proximal one of which is curved and 3 
distal ones; costal-marginal area finely powdered with dark; hinclwing with 4 lines. Bhutan and Sikkim. 
P. ruficosta sp. nov. (48 c). Forewing white, rather narrow; costal margin dull yellowish, in the distal ruficosta. 
half broader; crossed by 5 grey lines; the subbasal and proximal ones vertical, forming small crescents, dentate; 
a roundish spot, bordered with grey, on the discocellular; distal line oblique, forming small irregular crescents, 
dentate, the crescents between the veins 2 and 4 distinct; 2 subterminal lines of small crescents, but the crescents 
are here almost extinct, whereas the dents of both lines are marked blackish on the veins. Hindwing with 
3 distal lines and an indistinct short proximal line. Under surface without markings; costa dark brown with 
a subcostal more diffuse brown shadow showing through from above. Head, thorax and abdomen white, 
excepting the face which is above red-brown. One <$ from Mt. Goliath in Central Dutch New Guinea, February 
1911 (A. S. Meek). Type in the Tring Museum. 
P. auratifrons sp. nov. (48 c). Larger and with broader wings than ruficosta ; costal margin of a auratifrons. 
brighter yellow; the two proximal lines situate as in ruficosta ; the spot bordered with grey on the discocellular 
is larger and irregular; the distal grey line is oblique, irregular, zigzag; the two subterminal lines grey and zigzag; 
completely marked, the dents in neither of them on the veins marked with blackish. Hindwing with 3 distal 
lines and a proximal one; under surface white, the costa of the fore wing bright yellow; face above orange; 
forelegs and antennae yellow; vertex, thorax, and abdomen white. 2 GG from the Ninay Valley in the 
Central Arfak Mts., Dutch New Guinea, February till March 1909. Type in the Tring Museum. 
9. Genus: l^eucodrepaiisi Hmps. 
Proboscis present; palpi delicate, porrect, projecting a little beyond the frons; antennae thickened 
and flat in both sexes; middle tibiae with one, hind tibiae with two pairs of spurs; forewing with a curved costa, 
the apex projecting, distal margin oblique; on the hindwing both the angles and the distal margin are well 
rounded; on the forewing 6, 7, 8 forked, 9, 10 forked, 8 anastomoses with 9, 10 forming an areola; 11 
from the cell; wings glossy white with pairs of grey oblique lines. Type: L. idaeoules Hmps. 
L. idaeoides Hmps. (48 c and Vol. II, pi. 48 a). Forewing of a pure white, glossy; near the base idaeoides. 
an indistinct dark line; both wings with double oblique proximal lines, and double, undulating, dentate distal 
lines which are angular below the costa of the forewing; near the distal margin a dentate line; at the distal 
margin a black interrupted line. Sikkim in North India; mentioned by Leech also from the Wa-shan in China. 
L. nivea Hmps. (Vol. II, pi. 48b). Forewing less glossy than in idaeoides, without the basal line; nivea. 
the pair of proximal lines more oblique; distal area with 3 undulating lines equidistant from each other. Sikkim 
in North India; described from a single $. Mentioned by Leech from the Wa-shan in China.
