82 POLYTHRENA; TRICHOBAPTRIA; TRICHODEZIA; BAPTRIA; SCHISTOSTEGE. By L.B.Proft. 
13. Genus: 3*©lythreiia Guen. 
(See Vol. 4, p. 168.) 
pallida. P- coloraria H.-Sch. (Vol. 4, pi. lib) pallida Djakonov. Ground-colour not gold-yellow, as in the type 
form, but pale sulphur-yellow; the black markings also fewer and narrower than the normal. Founded on 
2 d'd' from Klutshi, Kamtchatka, taken in damp meadows, 21 June. The known range of the typical race is 
given by Djakonov as Altai, Transbaikal and some localities in E. Siberia, once also in Russian Karelia. 
14. Genus: Tricliobaptrla Prout. 
(See Vol. 4, p. 169.) 
exsecuta. T. exsecuta Feld. Notwithstanding some individual variability in all (or most) localities, this species 
shows some tendency towards race-formation. Felder’s type was from Nippon (Hondo) and ab. obscurior 
Th.-Mieg was probably also from that island; it should here be mentioned that “absence of the white band 
on the forewing'’ in the diagnosis of the latter is an unfortunate misprint or lapse and should read “of the 
lalifascia- hindwing“. The darker form is also supposed to have been taken at Hong-kong. — latifasciaria Leech (8 d), 
rm - on the other hand, was from Yesso (Hokkaido) and reaches still further north, since Matsumfra records it 
from S. Saghalien. 
15. Genus: TricSioilezia Warr. 
(See Vol. 4, p. 169.) 
Forbes is inclined to re-unite this genus and the preceding with Polythrena and points out that the 
latter “makes the transition to Eustroma” . In any case Trichodezia most certainly belongs, according to the 
genitalia, in the u Cidariinae” of Pierce (Lygris, Gidaria vera and various of its subgenera, such as Eustroma, 
Ecliptopera, Dysstroma, etc.) and should not be separated therefrom by the large number of comparatively 
unrelated genera which are here interposed. 
lalifascia- T. Jcindermanni Brem. ab. latifasciaria Prout (8 e). This seems rather characteristic of N. Japan, but 
na. no t py an y m eans confined to that part of the country. — leucocratia subsp. nov. (8 cl). Further material from 
i Qp na (Ta-tsien-lu, Moupin, etc.) confirms the status of the form mentioned in Vol. 4, p. 170 from Ta- 
tsien-lu. Antemedian (2nd) white line of forewing markedly oblique in its anterior half, consequently less 
parallel with the postmedian band, subtornal white dot obsolete on upperside; white band (or area) more or 
less strongly extended proximally or at least about the cell-spot, which is very conspicuous. Type from 
Ta-tsien-lu, 7500 feet, in the British Museum collection. 
16. Genus: ISaptria Hbn. 
(See Vol. 4, p. 170.) 
The actual affinities of this genus are much more obscure, the superficial resemblance to the two pre¬ 
ceding having been probably brought about by some similarities in the habits of flight. 
tibiale. B. tibiale Esp. (Vol. 4, pi. 6 c). This species deserves exhaustive study throughout the entire range 
of its occurrence, with a view to establish the extent of its geographical, as distinct from the individual vari¬ 
ation. One can generally recognize, at a glance, the majority of the Amur and Askold examples, with their 
comparatively small size and relatively broad white band of the forewing; also the large, narrow-banded ab. 
aterrima of Japan and some other colonies or local aberrations. But this needs ample material and a discrimin- 
albofalcata. ating judgment. Two aberrations have been named since the appearance of Vol. 4. — ab. albofalcata Scha- 
eversmanna- werda is intermediate between typical tibiale and typical eversmawiaria (8 d), which we now figure from 
ria ' Hakodate; white band of forewing a little shortened, that of hindwing not nearly reaching either costa or 
kauckii. hindmargin. Type from Herzegovina. — ab. kauckii Schille, founded on a pair of large specimens from Mount 
Rembrowez, East Carpathians, is scarcely differentiable from some eversmannaria , the band of the hindwing 
considerably broader, especially in the middle, than in Herrich-Schaeffer's type. — C. Finke (Intern. Ent. 
Zeitschr., Vol. 28, p. 138) has published an account of its extremely local occurrence, particularly as to its 
restricted haunts in the Gottinger Wald, and, 1 laving bred it from the egg, has given new details regarding 
the biology. The egg, he says, is milk-white and is laid exclusively on the edges of the underside of a leaf. 
The larva, until shortly before the last moult, feeds on the underside of the leaves; it feeds up in 3 or 334 
weeks according to the weather. The flight of the moth is entirely diurnal and it only descends from its 
altitudes for oviposition. 
17. Genus: Scliistostege Hbn. 
(See Vol. 4, p. 171.) 
decussc^a. S. decussata Schiff. (Vol. 4, pi. 6 d). Whatever may be the exact biological relationship between the 
different forms of this variable species, they are certainly more than mere “aberrations”, as they were made
