TRIGHOPTERIGIA; EMMESOMIA; HETEROPH LEPS. By L. B. Prout.

29. Genus: Trfchopterigia Hmps. 
(See Vol. 4, p. 186.) 
T. consobrinaria Leech (9 d). It was pointed out on p. 186 of Vol. 4 that by an error we had figured 
a small Acasis viretata under this name. We now give a figure of the true consobrinaria. 
T. rufinotata Btlr. (Vol. 4, pi. 13 a). Sterneck has recorded a few specimens from Ta-tsien-lu, June 
and August. 
T. sphenorrhyma Prout (9 d). A large species, recognizable also by its white ground-colour, strong 
black dots on all the markings of the forewing, subbasal and postmedian lines more continuously black. It 
lacks entirely the red dots of rufinotata, the only coloured markings being the faintly olive-yellowish bands. 
Described from 2 collected in Kashmir Valley, 7000 feet altitude, in June; a short series from Narkundah, 
collected in April, is also before me. 
30. Genus: Emmesomfa Wan. 
(See Vol. 4, p. 1S7.) 
A third species, formosana Bastelb. from Formosa, has been referred to this genus, but it is doubtless 
the same as Lobogonia bilineata Wileman and although the latter is the younger name, Wileman’s is the more 
correct taxonomy, so that the information given in Vol. 4 remains applicable. 
E. bilinearia Leech (Vol. 4, pi. 12 a) occurs also in Yunnan (vicinity of Yunnan-Fu). 
31. Genus: Heteroplileps H.-Sch. 
(See Vol. 4, p. 187.) 
A further “subgenus“ (perhaps eventually genus) has been added here; see Ortholithoidea below. Some 
further species and subspecies have also been detected, but no systematic study has been given to the group. 
A. Section Lygranoa: <$ antenna pectinate. 
H. fusca Btlr. (Vol. 4, pi. 6 d). I now doubt whether the true fusca of Japan occurs in the Ussuri 
district and Corea and suspect, rather, that these records rest on misidentifications. Even the widely distrib¬ 
uted Chinese race — sinearia Wehrli (9 d) differs considerably from fusca and I had it set aside as a probable 
species until Dr. Wehrli described it as a provisional subspecies. Larger, browner, the termen (especially in 
the $) appreciably more sinuate in its anterior half, apex consequently more produced, postmedian costal spot 
enlarged, line on hindwing stronger (especially in the $ beneath), underside yellower. Common in W. China, 
distributed also to the east of that country. 
B. Section Heterophleps: $ antenna ciliate.

H. clarivenata Wehrli (9 d). Similar to the Indian bicommata Warr. (the type of that author's genus 
Dysethia), which will be dealt with in Vol. 12; but I can scarcely agree with Dr. Wehrli in regarding it as a 
race thereof. Grey-brown, not purple-brown, the outer half of the forewing mixed with lighter scales, the 
veins light grey-yellow, termen of forewing more gibbous, postmedian more excurved, hindwing dark. Siao- 
lou, 1 A- 
H. pallescens Warr. (= pulveraria Leech MS., Seitz Vol. 4, pi. 11 d). Apparently not very common, 
and still known from Japan only, but not confined to Oiwake, as was suggested in Vol. 4. Mr. Joicey received 
it from Mt. Kuruma, near Kioto; flies in May and early June. 
H. nubilata Prout (9 d), only known in type A, from Vrianatong, Tibet, was described as a subspecies 
of sinuosaria, larger, less brown, with the cell-dot small, the lines weak, etc., but as the forewing is broader 
and the hindwing has a better-developed pocket at the abdominal margin I now regard it as a separate species. 
H. sinuosaria Leech (Vol. 4, pi. 11 c). Of the typical form of this species I know 1 also only the original, 
a A from Ta-tsien-lu, July. Our figure gives a very good idea of it, although the forewing is not quite bright 
enough and a little too uniform in colour. No other specimen which I have seen has the cell-mark so large, 
the subterminal line and its costal spot so well developed or the 2nd discocellular of the hindwing quite so 
strongly oblique inw'ard. A smaller form from Omei-shan at 7000 feet in July, represented by a worn q and 
a fairly good may be left with it for the present, though the colour is less bright, the 3rd costal spot un¬ 
developed and the cell-dot minute. — stygnazusa subsp. nov. (9 e) is the ordinary form about Kwanhsien (July- 
August), variable in size from 31—37 mm, similar in costal spots and cell-dot to the Omei sinuosaria but with 
heavy dark cloudings in, at least, the proximal half of the forewing and with the hindwing darker than in the 
other forms. Type $ in the British Museum.
