ved out of his own head. — ab. (? subsp.) obscurata Osthelder has the wthole forewing strongly infuscated 
with dark scales. Prevalent in the Allgau Alps where, according to Osthelder, even the lightest examples 
among the very long series figured by Daniel and Pfeiffer (Mitt. Munch. Ent. Ges., Vol. 9, p. 65) are darker 
than the general forms of other localities. 
25. Genus: Nothopteryx Prout. 
(See Vol. 4, p. 183.) 
Even more that Acasis, this ‘‘genus’’ is a loosely-knit assemblage. Founded on carpinata Bkh. as geno¬ 
type, and intended primarily for those species in which the d hindwing has the costal vein separate from the 
subcostal, merely connected at or beyond the end of the cell, it has been made to include a few species with long 
palpus, one at least in which the costal of the hindwing anastomoses, one or two in which the discocellulars 
of the hindwing are biangulate and others which show some minor anomalies. I have added a few structure- 
notes to the meagre ones given in Vol. 4, but do not pretend to have exhausted the subject. 
N. ustata Christ. (Vol. 4, pi. 6 f). Not a true Nothopteryx, inasmuch as the costal vein of the d hind¬ 
wing anastomoses strongly with the cell; discocellulars fairly straight. 
N. sabinata Hbn.-G. teriolensis Kitt is light grey, not brown, the median band of the forewing di¬ 
stinctly light in its ample central part and bounded by white-grey on each side, the underside with median 
band obsolete. Oetztal, Tyrol. 
N. obscuraria Leech (Vol. 4, pi. 6 g). To the range are to be added some localities in Szechuan: Ta- 
tsien-lu, Kwanshien, etc. 
N. polycommata Schiff. grisea Djakonov. A good local race, perhaps species, small, narrow-winged, 
weakly marked. Palpus somewhat shorter and more slender, antenna likewise more slender. Forewing uni¬ 
form grey, almost without the brown scaling of the type, only the median area tinged with brown and with 
the veins darkened. Minussinsk; probably also a very worn Krassnojarsk $ belongs with it. 
N. ussurica Welirli (9 c). Founded on a which has long palpus, and therefore very naturally as¬ 
signed to Acasis , in the neighbourhood of muscigera (Vol. 4, pi. 12 b), though the discocellulars of the hind¬ 
wing are merely very oblique, not biangulate. The d, however, has the palpus quite moderate, the costal of 
the hindwing free, connected with the 2nd subcostal beyond the cell, and shows evident relationship to ex- 
portatci (9c). The blackish shading along the inner margin as far as the post-median, the strongly curved dark 
subbasal band, the brownish, not or scarcely darkened median area and the subt-riangular costal shade beyond, 
followed distally by a conspicuous pale patch, are all characteristic. The specimens before me were collected 
at Okeanskaia by H. Kardakoff in May, but the type is from Sutschan, S. Ussuri, June. 
N. exportata Stgr. (9 c). Similar in structure to ussurica but duller in colour, the forewing with much 
less curved or bent markings, especially in the proximal area, darker median band and the subterminal not 
expanded into a large whitish costal spot. Okeanskaia in April, collected by Kardakoff. A much greyer, 
superficially more grisearia- like $ from Sutschanski-Rudnik, June, in my collection has the long $ palpus 
of ussurica. 
N. grisearia Leech (Vol. 4, pi. 11 c). Hindwing of the d with the costal vein connected with the 2nd 
subcostal b e y o n d the cell (much as in carpinata, to which the relationship is evidently fairly close). Hind- 
tibia of the d wit-h the hair-pencil reaching about to the middle of the 1st tarsal joint. 
N . carpinata Bkh. ab. fasciata Prout (9 d). We figure a d from Rannoch, Perthshire, probably its 
best-known habitat. — ab. nigra Bretschneider is an altogether melanic form. From a worn melanic $, 3 out 
of the 12 specimens bred were of this form; others were taken in the same district (Wilsdruff in Saxony). 
N. hemana Btlr. (Vol. 4, pi. 6 g). Venation about as in carpinata , palpus perhaps a trifle longer, spurs 
of hindtibia in the d extremely short. 
N. terranea Btlr. (Vol. 4, pi. 11 c, not 12 c as indicated on p. 184). Venation again similar to that of 
carpinata, but with the 2nd radial inclined to arise very much before the middle of the discocellulars. Occurs 
in the Ussuri district as well as in Japan. 
N. misera Btlr. (Vol. 4, pi. 11 c). Structure of the d rather exceptional for the genus: forewing with 
the 1st radial often from about the anterior angle of the cell (in the type and one or two other examined spe¬ 
cimens short-stalked; in all other Nothopteryx yet observed it is well stalked); hindwing with costal vein 
rather remote, the connecting bar just before or at the end of the cell, the 2nd subcostal stalked (though only 
quite shortly); face rather rough; palpus moderate in the shortish-moderate in the d-
