CIDARIA. By L. B. Prout.

narrowed in castanea than in hortensiaria . The name dimidiaria Motsch. (misprinted dimidiana ) has sometimes 
been applied here; Motschulsky can hardly be said to have described his species, which he likened to 
picata (Vol. 4, pi. 10 b) though much smaller, but I cannot possibly reconcile it with hortensiaria. To the range 
must be added Szechuan. 
C. muscicapata Christ. (Vol. 4, pi. 9 e). Sterneck records from Ta-tsien-lu and Omisien a larger form muscicapata. 
which belongs, if not actually to muscicapata , at least to this group in the strictest sense. I recognize 4 or 5 
species thereof, almost exclusively Indo-Australian and probably very variable, but hope to give them closer 
attention in Vol. 12. — obfuscata Warr. (see Vol. 4, p. 234) is not at all likely to be a race of muscicapata, but obfuscata. 
scarcely concerns students of the Palearctic fauna unless the Szechuan specimens (see above) belong to it. The 
series recorded by Wileman from Japan (Oshima, Yezo, in May; Yoshino, Yamato, in June, July and Sep¬ 
tember) as plumbeotincta was clearly misidentified and lie himself later transferred it to muscicapata. If musci¬ 
capata has a race in India it is more likely to be hareconia Swinh. or buda Swinh., for these have the sharply defi¬ 
ned median band. 
Subgenus Basyuris Guen. (see Vol. 4, p. 234). In the German translation a word is omitted; read: 
n i c h t doppelt gewinkelt. 
D. polata Dup. (Vol. 4, pi. 9 f) ab. contrastata Schawerda, received from a dealer as from “Greenland ", contrastata. 
must be mentioned here, as the author suspected it was rightly from Lapland. Forewing with strong contrasts: 
median band dark, the adjacent areas broadly white-grey, unmarked. 
Subgenus Entephria Hbn. (see Vol. 4, p. 234). 
This subgenus and its immediate outliers may be recommended for more detailed anatomical research. 
The “special organ” of the genitalia (calcar of Pierce), which impressed Chapman as a striking differential 
character, certainly separates Entephria definitely from some superficially similar alpine Cidaria, but would 
seem, as he said, to bring in also incultaria — an improbable addition on biological grounds. The calcar 
of Xanthorhoe probably corresponds to it, but the so-called “calcar” of Epirrhoe is a very different formation. 
Forbes has called attention to the very narrow, “strap-like” scaling of the forewing in most true Entephria 
and I have to a large extent confirmed this. 
C. ignorata Stgr. (13 e). We figure a topotypical $ from the Elwes collection (28 July 1872, Chri- ignorata. 
Stoph) ; it has the median band perhaps slightly better defined than in the type. The discocellulars of the 
hindwing are scarcely more angled than in ravaria, the 2nd radial from about the middle, or very slightly before. 
C. caesiata Schiff. (Vol. 4, pi. 9 f) has been somewhat precariously recorded from Japan by Suzuki caesiata. 
(as caeciata). I have not seen his form. — ab. hauderi Stauder (= insignata Schawerda). Median band solidly hauderi. 
dark, much narrowed, proximal and distal areas uniform whitish grey, without the dark lines, only some weak 
dark shading to the white subterminal, at least proximally; white lines bound the median band. Salzkammergut 
(Stauder) and the Dolomites. — ab. strata Lange is a slight modification of ab. nigricans Front (Vol. 4, p. 235), airata. 
with all the pale markings obsolescent excepting the subterminal. — ab. paradoxa Lange is a striking form paradoxa. 
(only 4 examples known), the forewing smoky black, only with the basal patch and a narrow central stripe 
white-grey; hindwing with proximal half white-grey, distal half blackish. — ab. lacteofasciata Lange has similar lacteofas- 
basal and median areas to paradoxa, the rest of the forewing less extreme, being rippled with light lines. — cud a. 
ab. divisa Lange (= mediodivisa Stauder). More nearly typical but with the median band tripartite as in some divisa, 
lacteofasciata (white centrally, rather narrowly black at either side). This and the rest of Lange’s aberrations 
were obtained by breeding from larvae, which, 1 in his experience, occur only on Vaccinium myrtillus. Upper 
Freiberger Mulde. — ab. clarior Osthelder is more whitish, the median band as in divisa, only with its central clarior. 
pale part typically narrower. Type locality: N. Tyrol. — glaciata Germ. (13 e). Like caesiata everywhere, this giaciala. 
is decididly variable, but it is nearly always smaller than the typical race, certainly on an average darker, 
occasionally very similar to norvegica, which is also generally rather small. — italicata Costantini is diagnosed italicata. 
as paler, glaucescent, the stripes more diffuse and cloudy, “etc.” and said to constitute a subspecies in the beech 
region in the Apennines, common in July and August. This was only intended as a preliminary note and was 
not mentioned by Dannehl in his studies of the Italian fauna. — abruzzensis Dannehl, however, does not fit abruzzensis. 
accurately with the above characterization, though it is also in a sense “preliminary”, being made contingent 
on its proving racially constant. Rather small and narrow-winged, lighter and more yellowish than the type, 
thus an antithesis to the following form. Abruzzi (Gran Sasso, etc.). — - cibiiliaca Dannehl (= cibiniata Dan- cibiniaca. 
nehl) is a very large and robust, variegated form, prevalent in the Cibins Mountains (S. Carpathians). 
C. fuscaria Leech (13 e). We figure the type from Ta-tsien-lu. I have met with no further examples, juscaria. 
C. flavicinctata Hbn. (= flavicincta Klem.) (Vol. 4, pi. 9 g, as flavocinctaria). The forms from the fiavicindata. 
Balkans are generally smaller and slighter than those of the Alps. The naming of the individual forms, especially 
those with the yellow scaling suppressed, has evidently proceeded too far. — ab. grossi Hoffmann & Klos, grossi.
