C. albovenosata Heydem. (11 h). Another somewhat, isolated species, unless possibly related to singularia ; uibonnu>su- 
the genitalia show considerable divergences from true Dysstroma. The antemedian line — somewhat obliterated 
by the rubbed condition of this part of the wing is as oblique as in corussaria and the narrowed end of the 
median band is marked with velvety black. Very characteristic is the pair of very fine, parallel white lines 
which succeeds the median band distally and sends inward deep projections on the veins between the lobe 
of the postmedian and the hindmargin. Founded on 3 from Tse-kou, S. W. China, in the Wehrli collection. 
(C . brunneata Pack., mentioned in Vol. 4, p. 222 on account of its reputed occurrence in Belgium (!), 
has of course nothing to do with the Palaearctic fauna and must be deleted.) 
Subgenus Xanthorhoe Him. 
(See Vol. 4, p. 222.) 
I have removed from this subgenus its section C, which could be easily defined separately, but have 
not redistributed the residue except in the few cases where some structural character had been overlooked 
which contradicted the diagnosis. For hortensiaria see the subgenus Loxof idonia ; for apiciata, Coenotephria; 
for diver gens the genus Piercia. 
A. Antennal pectinations fully developed, usually one pair to each 
segment (b ut see fluctuata, disjunctaria, incursata). 
C. munitata Hbn. (12 b). Schawerda considers that Hubner's figure represents the northern form munitata. 
of this species, which is generally recognizable by its smaller size and darker colouring. A glance at the figure, 
however, raises doubts concerning the correctness of this judgment; and the inherent probability of a Central 
European origin has become a certainty in that Hubner’s manuscript writes “ munitata Hw.” (i. e. Hochen- 
warth, M. S.) and indicates that he is reproducing a painting by Schiffermuller. I therefore continue to 
cite as a synonym collinaria Metzn., well described from the Austrian Alps. — arcticaria Kef. consequently, arctic-aria. 
with locality “Iceland”, is the correct name for the North European race. The figure in Germar is crude and 
much too brightly coloured, but evidently represents the brightest of the variable Icelandic forms. — ab. in- infuscata. 
fuscata Prout , or something closely similar, is apparently the prevailing form (ab. loc.) at Muonio, Lapland, 
unless Lord Rothschild’s series of 6 3 9$ was specially picked. — ab. interrupta nov. ( = algidata Culot, interrupta. 
nec M os chi.) is an aberration from Iceland with the band much narrowed, behind the middle interrupted. — 
ab. fuscifascia nov. (Vol. 4, pi. 8 1, as munitata) is another northern aberration, the band blackish, the rest of fuscifascia. 
the forewing and at least the distal part of the hindwing remaining whitish. Wolff has figured a pretty ex¬ 
ample from the Faroe Islands. — ab. pauperrimata Christ. The original series came from Kurusch, S. Daghestan; pauperrhna- 
we have not been able to obtain a figure. ta 
C. castanea Warr. (12 b). Slightly narrower winged than munitata (12 b), termen of forewing a little more castanea. 
oblique, proximal group of lines well developed almost as far as the antemedian line, which is less curved than 
in munitata; median band in the $ rather narrow, in the 9 broad, without sharply black edges, but with dusky 
brown traversing lines, postmedian line bent inward close to costa, distal area, especially in the 9, more suf¬ 
fused than in munitata, showing a tendency to develop a costal patch somewhat as in designata. Kashmir, 
the type $ from Gurais Valley, a variable series subsequently collected at Gulmarg. Warren saw in it a near 
resemblance to C. ( Euphyia ) subangulata, but this does not seem to me particularly obvious. 
C. kamtshatica Djakonov. Probably related to munitata, which occurs with it in Kamtshatka in forms kamtshatica. 
that do not differ from the European; quite distinct in the genitalia, as well as in some external characters. 
Perhaps on an average larger (length of a forewing 16 mm). Ground-colour much lighter and more uniform 
(than in m. arcticaria ?), yellowish white with an admixture of grey-brownish scales; the only conspicuous mark¬ 
ing is the median band, which is darkened in its anterior half only, then (behind the median vein and its 1st 
branch) suddenly narrowed and appearing to be of the ground-colour, chiefly defined by its indistinct boundary¬ 
lines; a weakly darkened basal patch, the other markings shadowy. Hindwing a little lighter, almost entirely 
without markings. Valve and calcar much longer than in munitata, saccus quite differently shaped, aedoeagus 
without the strong backward-directed spines, etc. Petropavlovsk in the first week of July, a good series. 
C. inconsiderata Stgr. (13 b). Wehrli records this species from Marasch, at 400 to 900 m, flying in inconsidera- 
September. ta - 
C. fluctuata L. (Vol. 4, pi. 9 a) does not absolutely conform to the diagnosis of Xanthorhoe given in fluctuata. 
Vol. 4, but would fall into Turner’s “genus” Diploctena (“antenna in <$ with two pairs of fine pectinations 
on each segment”), for the secondary, cilia-bearing processes, though short, are veritable pectinations and 
are so treated by Forbes in his analysis. As regards the geographical distribution. I cannot find definite con¬ 
firmation of its occurrence in North Africa and suspect there has been some confusion with its nearest ally 
disjunctaria ; on the other hand iduata Guen. (North America) may well be considered its representative species.
