LEPCHINA; PANACEA. By Dr. A. Seitz.

A. omissa R. & J. (03 c). Shaped exactly like the preceding species, but the forewing much less marked, omissa. 
especially with fewer transverse bands; hindwing distally with a more rust-colourecl tint. North India: Sikkim 
and Bhutan. Probably not rare, but mostly mistaken for the preceding species. 
A. pseudomissa Mell exactly resembles omissa, but the margin in both wings smooth, not gnawed out pseudo- 
below the apex, but only slightly projecting. Oblique stripe of forewing produced as a distally directed streak. missa. 
In the large preapical light costal spot the median one of the 3 dark undulate lines (which are distinct in the 
otherwise similar castaneci [Vol. II, pi. 39 e]) is present, sometimes also the outermost, whereas the innermost 
is absent. Northern Kwang-tung. 
A. castanea R. <£■ J. (= anceus Leech p. p.) (Vol. II, pi. 39 e). Recognizable by the very slight indenture casianea. 
of the margin of the forewing below the apex. The is somewhat more similar to sericeus in the marking and 
colouring than the $. As to further particulars we refer to Vol. II, p. 251. Typical specimens are from Japan. 
— kuangtungensis Clk. are specimens from Kwang-tung with a lighter under surface; the white spotting at the huanytun- 
costal margin of the hindwing is more intense, and the anal area and centre of the hindwing beneath are lighter, 
too. — ab. conspicua Clk. are AC of the summer form, in which the forewing shows rust-coloured layers. — conspicua. 
Larva sap-green, granulated yellowish-white, with a rough yellow horn, beneath there are yellow flat oblique 
streaks. On vine and Cissus japonica (Nagano). Pupa uniformly thick, at both its ends very much rounded 
like most of the pupae of Acosmeryx. It occurs in the palaearctic region in the Hokkaido and in Hondo, but 
in China it goes farther to the south. Not common. 
A. yunnanfuana Clk. Above similar to the form subdentata, beneath more like castanea or omissa. The yunnan- 
greyish patch at the costal margin at the subapical area extends to the 2nd radial, and somewhat duller at the 
margin as far as the 3rd. In this brightening there are, between the costal margin and the 5th subcostal branch 
and between the latter and the 1st radial, double rows of proximally concave lunulae. Hindwing above 
unicoloured dark brown; only from the anal angle to the centre of the wing there is a feeble brightening. 
Described according to a single $ from Yunnan. 
50. Genus: X^e}>chiaia Oberth. 
The genus is founded on a single species in the Coll. Oberthur, looking like a stunted Acosmeryx. The 
eyes are smaller than in the latter, with brows, the last antennal joint not filiformly prolonged, the tibial spurs 
shorter, the middle tarsus without a basal comb. 
L. tfidens Oberth. Unknown to me in nature. Of the size of Perg. elpenor. Forewing at the margin Mctens. 
dentate, with a point at the apex, one below it, a projection in about the centre of the margin; margin of 
hindwing curved. Forewing above violettish-grey, traversed by velvety brown lines and spots. Three of these 
lines extend parallel to each other from the costal margin to the inner margin, behind it a triangle with the 
apex towards the costal margin. In the cell a distinct ochreous spot. Darjeeling. 
51. Genus : Panacra Wkr. 
The species of this genus are mostly very much alike, their colouring and marking strikingly resembles 
bark, and when at rest they take up so strange a position that they can hardly be recognized as insects. Still 
more stupefying is the larva which was minutely observed by R. Mell. It presses close against its resting 
place, and does not move in the least on being disturbed, thus resembling a shoot of the food-plant. ‘'The 
insect may be pushed and pinched, it remains motionless.“ — The imago is characterized by its very large head 
and the uncommonly slender and pointed abdomen of the male. Palpi very large, antennae rather plain, in 
the d bristle-shaped, in the $ feebly clubbed, last segment narrow, long conical, not filiformly prolonged, not 
scaled, with long bristles. Tibiae spineless, middle tibiae with almost equally long spurs, the spurs of the hind 
tibiae very unequal. Pulvillus and paronychium present. — The genus is purely Indo-Australian. 
P. pulchella R.&J. (64 a) is the most beautiful species. Forewing with 2 white longitudinal lines, pulchdla. 
the upper one branching off net-like. Hindwing deep orange-red with a blackish marginal band. New Guinea. 
P. michoiitzi R. <£■ J . (64 a) is another New Guinea species. The upper white line of the forewing forms micliolitzi. 
no meshes, but only 2 strangulations towards the apex. Hindwing lighter, more dark golden yellow. 
P. excellens Rothsch. Head and thorax, as well as the first abdominal rings above dark olive green excellens. 
like the forewing which, however, shows a yellowish flesh-coloured spot near the base, which is divided by 
black spots into 3 parts; apical third silvery grey, scantliy dusted olive. The median transverse band of the 
forewing is pink, outside bordered with orange-red. Hinclwing in the basal two thirds orange, marginal third 
clingy brown. Oetakwa (New Guinea). 
P. busiris Wkr. (64 a). Thorax and forewing as far as the marginal area green, shaded with brownish; busiris. 
marginal area wood-brown and disfigured like a chip of wood by a double indenture below the apex. Hindwing 
dark brown. The imago is unmistakable. When it rests, it keeps its snout and abdominal end pressed upon
