median band. etc. A glossy, rather sharply-marked species, with the subterminal and its accompanying shade 
not lunulate. Nissa, Elburs Mountains, 3000 m, only the $ known, discovered by Mr. F. H. Brandt. We figure 
a moderately sound specimen kindly presented to me by Mr. W. Brandt.

Proud. Specimens recently obtained in the Elburs Mountains evidently belong here. 
p. 78, to 0. adornata Stgr. This was met with in S. Kansu at high altitudes by Dr. David Hummed on 
the Sven Hedin expedition. 
p. 80, after K. loxobathra : 
K. lakearia Oberth. (Vol. 4. pi. 6 i). Djakonov records 4 $9 from different localities in S. Kansu, ca. 
2850- -3000 m, 2 being as large as oberthuri, 2 much smaller, but all agreeing completely in the markings. 1 
suspect, however, that these may be forms of loxobathra-, in any case, he has independently pointed out the 
error of confusing lakearia with oberthuri Alph. of which he has carefully compared the type.

contrariata, , corresponding to O. coarc fata, infuscata. but not racial. Densely irrorated with black-grey, a dirty 
whitish band just outside the postmedian, which is charply blackish, as is also the apical dash of forewing.

p. 81, to S. depeculata Led. In Vol. 4 (p. 168) I described Lederer's figure as showing on the hind¬ 
wing a narrow white “median” band; strictly speaking, this should read “postmedian ", but the ground-colour 
of the whole wing, notwithstanding the density of the irroration, is called white. — symmora subsp. nov. (13 c), 
from the Elburs Mountains, seems to differ sufficiently from the name-type to demand a separate name. The 
hindwing on the upperside has no white element, or only very faint indications of a slender line, and is in fact 
almost concolorous with the forewing. The originals are in the Tring Museum, the type specimen a 9 from 
Hashtar, Demavend: pretty constant at altitudes of 2600 to 3600 m. thibetaria Oberth. The note on p. 81 
regarding “the costal patch of the forewing” was brief at the expense of clearness. There are 2 main forms 
(or possibly species, though no difference has yet been discovered in the $ genitalia), but in neither of them 
is the dark post median band of the forewing continued so far hindward without touching the terminal band 
as is the case in narzanica (see Vol. 4, pi. 6 b). In Oberthurs type form it almost or completely runs into 
the terminal band at the radials and 1st median. Djakonov adds to my differentiation that the ground¬ 
colour in thibetaria , especially of the hindwing, is much cleaner silver-white than in narzanica; he says 
that the form from Kansu agrees with thibetaria. — ab. (loc. ?) lusoria nov. is an extreme development, 
broad-winged (the costal margins somewhat more strongly arched beyond the middle than usual); the 
border and the oblique band rather broad anteriorly, coalescing strongly, the underside with the po¬ 
sterior part of the hindwing whitened in the median and the subterminal areas, both wings with some 
very characteristic vinaceous suffusions, that of the forewing on the proximal part of the dark apical 
region and overflowing on to the oblique white band and the whitish subapical patch, that of the hindwing 
(in part even brighter) between the radials (not reaching termen) and running inward in posterior part of cell. 
E. Tibet: Dii Chu Valley. 12 000 feet, 11 July 1936 (R. J. H. Kaulback), a fine <$ in the British Museum. I 
at first supposed this a separate species, but it is apparently only a high-altitude form; among some 200 nar¬ 
zanica I have detected about a dozen (Ta-tsien-lu, Tseku and Yaregong) which furnish transitions, at least in 
the progressive manifestation of some vinaceous suffusion on the underside. — f. brachynesis nov. This is the 
second principal form mentioned above and, strictly speaking, includes the specimen figured as thibetaria (8 d), 
although some examples are more extreme. Costal band reduced, often subtriangular, terminating about the 
3rd radial (type) or even the 2nd, sometimes extended to the 1st median, but in all cases separated here from 
the border by a clean white band of 1—2 mm width. Border of .hindwing extremely narrow or wanting. W. 
China: Ta-tsien-lu (loc. typ.), Mupin. Tay-tou-ho, Yaregong, Tchang-kou, etc., apparently together with f. thi¬ 
betaria in a proportion of perhaps 20 per cent. discreta subsp. ( ?) nov. (18 k) is the only form which I have 
seen from Koko-nor. Costal band of forewing always small and well isolated, nearly as in brachynesis, from 
which it differs in that the hindwing, more particularly in the $9- has a dark border as in the “first principal 
form” of thibetaria: moreover the dark border of the forewing is less angled about the 2nd radial, its white 
proximal border and the preceding “costal band” a little less obliquely placed; find wing beneath with more 
white, at least in the apical region. Type <$ in the Tring Museum. 
djalonr.ri. p. 81, to S. danilovi djakonovi Alph. According to Djakonov, who records a slight modification from 
S. Kansu, the most important characteristic of this Nan-shan race lies in the completeness of the terminal 
black band of the forewing, which reaches the hindmargin. while in the Altai and N. Mongolian examples it
