only citrata that occurs there, though Staudinger has cited the locality 
to both ; Alpheraky, who is one of the obscurantists to whom there is 
but one species in the group, distinctly says (Horn. Mem., ix., p. 842) that 
“ the specimens from Kamtchatka stand nearer to the form immanata, 
though they are lighter in colour; ” he says they are neither note¬ 
worthy for particularly brilliant colouring nor sharp markings. For 
Japan, Staudinger’s query may probably be deleted. The Japanese 
forms seem very variable, and may contain more than one species. 
Pryer (TV. Asiat. Soc. Jap., xii., pt. 1, p. 79) records both russata and 
immanata from Yokohama, but gives no detail, and perhaps meant 
cinereata and citrata. Leech (Ann. Mag. Nat. Hist., ser. 6, xix., p. 669) 
says : “ The typical and marmorata forms both occur in Japan and 
China.” In other words, the forms from these countries include both 
dark-banded and white-banded. 
I have North American forms referable to citrata from Calgary, 
from Wellington, B.C., and from Alaska (the last-named an ochreous- 
toned form, reminding of some Iceland specimens), besides one or two 
without exact localities, but which, I believe, are from the eastern 
States ; the British Museum has them from Anticosti, Nova Scotia, 
Trenton Falls (New York), Rouge River (Oregon), Mendocino Co. 
(Cal.), and Esquimalt. The prevailing form is some phase of ab. 
punctum-notata ( = marmorata), with more or less white central area; 
the black-banded form (ab. immanata, Haw.), seems rarer,'* but is more 
English-looking; the paler one generally has the reddish parts of a 
rather different colour from that which is normal in Europe, a colour 
which I can only vaguely indicate, by suggesting that a little orange 
is taken out of the red-brown, and a little purple substituted. The 
hindwings and undersurface are pale, as in European citrata, but the 
line on the underside of the hindwings is variable, only very occasionally 
making the angle which is demanded by Messrs. Webb and Fenn in 
their differentiation of the species. Kellicott’s Hydreomena traversata 
(not transversata, as misquoted in Dyar’s list), from Petoskey, Michigan, 
seems to me a good description of rather large (86mm.), but otherwise 
typical American citrata ab. punctum-notata. As a rule, the American 
forms of this species are not larger than the European, but there is 
much size variation in both hemispheres. 
Cidaria mulleolata, Hulst, seems to be the only name that can 
possibly be available for the large, western American species which we 
have differentiated by the genitalia (see supra), and which occurs in 
the British Museum collection from Washington Territory, and in my 
own from Vancouver and Wellington, B.C. The very large size 
* I have not seen it from eastern North America, but have two from Welling¬ 
ton, B.C., while single specimens from Rouge River and Mendocino Co., at the 
British Museum represent it. I have also a Calgary specimen of typical citrata 
(i.e., intermediate between the white-handed and black-banded forms).
