310 HYSTERURA. By L. B. Pboitt. 
but the brown colouring is somewhat darker, the markings more intense, the 5th white line (1st antemedian) 
less sharply angled on the median vein; sometimes scarcely distinguishable. Khasis, type o (Shillong) in the 
British Museum. atherma Prout (Suppl.-Vol. 4, pi. 10 f). White lines more sharply developed, dark parts 
more uniformly olive-brown mixed with fuscous, median area not conspicuously bicoloured. Kwanhsien. 
Szechuan. Another race is found in Japan and Corea. 
L. complicata Butl. (Vol. 4, pi. 13 a) daetylotypa subsp. nov. (31 d) is much greyer than the name-typical 
complicata of Japan, especially so the distal area, which shows scarcely any indication of the cinnamon-brown 
of that area of c. complicata. Formosa: Kanshirei (A. E. Wileman). both sexes in the British Museum. 
B. Section: 3 forewing without hair-pencil; 1st median vein of hindwing 
more or less stalked (Lobogonodes). 
L. taiwana Wileman (31 d). Very near erectaria Leech from Japan (Vol. 4, pi. 13 d). More yellowish, 
but chiefly distinguishable by the angulated antemedian line. Formosa: Arizan; only the type $ known. 
L. permarmorata Bastelb. (Suppl.-Vol. 4, pi. 10 f). Rather larger than the average Lobogonodes and 
with much less sinuous postmedian line. The broader oblique streak from the apex and the more conspicuous 
white central spots are further characteristic. Described from Arisan. Formosa. A worn 9 from Tu-pa-ko 
seems to agree exactly with it. 
46. Genus: Hysterura Warr. 
(See Vol. 4, p. 206; Suppl.-Vol. 4, p. 104.) 
Even this might also be regarded as a section, or group of sections, of Eustroma , though the almost 
constant (sometimes long) stalking of the 1st median of the hindwing affords perhaps a good character for its 
separation. The species are further bound together by the similarity of their pattern and the tendency — not 
always carried far, however - for the hindwing to assume an irregular shape, somewhat as in Lobogonodes. 
The texture and pattern, as well as the shorter palpus, separate them from Lobogonodes (sect. typ.). Palpus 
moderate; antenna and generally the venation of forewing (but see cervinaria ) as in Eustroma, also the non- 
biangulate discocellulars of the hindwing. In most of the forms the Eustroma hair-pencil of the forewing beneath 
is well developed; in some the S develops also lateral pencils on the abdomen posteriorly and a specialized patch 
in the folded hindmarginal area of the hindwing. Almost exclusively Himalayan and West Chinese. Type 
of the genus: multifaria Swinh. 
H. literataria Leech (31 c) (Vol. 4, pi. 13 n). Strictly speaking, this and the following should form a 
separate section, as the hair-pencil of the forewing is wanting; literataria is. however, so closely similar in 
facies to cervinaria and hypischyra to multi faria that I suppose the presence or absence of the pencil to be here 
of little genetic importance. Szechuan, the type from Pu-tsu-fong. 
H. hypischyra Prout (Suppl.-Vol. 4, pi. 10 e). Larger than literataria, termen of hindwing more bent 
at the 3rd radial, though less so than in multi faria. Forewing similarly marked to that- of multifaria but paler, 
hindwing whitish, with distinct postmedian line above. Szechuan? the type from Tupa-ko; 4 from Ta- 
tsien-lu, with the hindwing somewhat variable, on the whole slightly less white. Abdomen and hind-marginal 
area of hindwing in the <$ with the pencils and sex-patch respectively. 
H. cervinaria Moore (31 c). Forewing of S beneath with a rather slender buff pencil. Hindwing of $ 
scarcely irregular in shape or clothing, though a rather long fringe on the middle part of the abdominal margin 
may indicate a slight specialization. Erratic in venation, the areole oft-enest simple, the 1st median of the hind¬ 
wing not quite always stalked. Darjiling (type) and the Khasis. 
H. vacillans sp. n. (31 c). Intermediate in tone and in markings (amount of narrowing of the hind part 
of median band and degree of obsolescence of subterminal spots after the first few strong ones) between cervinaria 
and multifaria ; shape more as in the latter - apex of forewing not produced, termen of hindwing angled at 
1st median, but not so strongly. Hair-pencil of $ of the light colour of that of cervinaria. Forewing with the 
pale line along the median vein. Markings of underside rather weaker than those of multifaria. but with the 
postmedian of the hindwing almost equally irregular. On an average smaller. Ta-tsien-lu district (type q), 
Siao-lu (1 3) and eastern frontiers of Tibet (1 rf), all from the Oberthur collection. Here will doubtless belong 
the 1 Ta-tsien-lu “ multifaria ” recorded by Sterneck (see Suppl.-Vol. 4, p. 104). 
H. multifaria Swinh. (31 d) shows the special characters well developed on the abdomen and both 
wings and has an almost rectangular tooth at the 3rd radial of the hindwing. Described from Darjiling, but 
reaches Kashmir as well as the Khasis.
