CIDARIA. By L. B. Prout.

forewing with sharply marked, strongly dentate lines, the white band beyond also sharp, broad, divided. Hind¬ 
wing very light. Possibly other southern forms of hydrata should be united with it. 
C. lugdunaria H.-Sch. (Vol. 4, pi. 13 e). Raebel has added Germany to the recorded range, giving a 
very interesting account of its discovery at Laband, near Gleiwitz, Upper Silesia. The proximal areole of the 
forewing is variable, sometimes minute or wanting. The life history was made known by Chretien in 1922, 
Rebel in 1923 and Raebel in 1927. The egg is laid on a seed-capsule of Cucubalus baccifer, into which the 
newly-hatched larva burrows, feeding on the seeds. It is white with blackish head and, in its later stages, red¬ 
dish subdorsal lines. It may be found in August and September and is full-fed in about 3 weeks from hatching. 
— ab. apantharia Dannehl. The white markings of the forewing wanting, the brown-black element scarcely 
noticeable in the unicolorous grey-violet ground-colour. Hindwing nearly as dark and uniform. Single specimens 
from Klagenfurt and Terlan. 
C. bifaciata Haw. (not bifasciata, as generally misquoted). Milliere says that the ordinary Marseilles- 
Cannes form is like the British and mentions also a Lyons “race”, which is a little larger and a little lighter. 
Most of the southern French which I have seen seem to be s m a 1 1 e r and lighter than our ordinary British 
bifaciata, sometimes showing a slight approach to euphrasiata. In the Balkan Peninsula bifaciata reaches Albania, 
as well as the Dobrudscha. The British Museum has even a few examples from Cyprus, too few and too im¬ 
perfect to generalize upon. — scitularia Rbr., from Corsica, is apparently a race, not a synonym as given in 
Vol. 4 (p. 261), yet is certainly variable. According to Reisser it is found among Euphrasia lutea and at an 
altitude of 850 m appears in August and September, not, as Rambur gave, in June. On the whole somewhat 
brighter and more variegated than the name-typical form. — euphrasiata Mill. (= flavosparsata F. Wagn.) 
(16 b). I have now seen examples of this strikingly distinct form from Albarracin, where it occurs from August 
to October and was first recorded as minorata, then as a new species. The possibility that it is a species is not 
yet entirely excluded, but it seems more probably a very small grey race of bifaciata. The original type-locality, 
which Zerny says was not given, is supplied by Milliere's “Cat. Lep. Alpes Mari times”. 
C. parvaria Leech (Vol. 4, pi. 7 k). This is evidently variable as regards the form of the median band, 
unless there are two very closely allied species mixed. The originals were 2 GS from Pryer's collection, thus 
almost certainly from Japan, and Leech suspected they came from Yokohama. This form agrees with the 
Ussuri ablegata, so far as I know it, and Franck has sent a very similar <$ from the Yu Chi Valley, near 
Kwanhsien, slightly intermediate, in the width of the band, towards the following. — albidivisa Warr. The 
only other Japanese parvaria yet known to me is a $ from Yoshino, Yamato (Wileman) and belongs apparently 
to the form albidivisa, which otherwise I had supposed to be the Punjab and Assamese race. It has the median 
band considerably broader, especially at the costal end, where it is fully (or more than) twice as broad as at 
hindmargin; moreover its distal edge is acutely angled in the middle and the pale shading between its angle 
and the termen is increased. The distinction is not (unless on Japan) sexual. 
C. ecbolobathra sp. n. (18 a). Palpus moderate, triangularly scaled above. Abdomen slender, parti¬ 
cularly in the rf. Forewing distinguishable from that of the adjacent species by the whiter proximal area; base 
clear, bounded only by narrow dark costal and subbasal lines, the latter somewhat interrupted; band between 
this and central area weak; median band well darkened, rather narrow, with indications of a browner line near 
it on each side; white midterminal spot, unless in the $, much less developed than in parvaria. Hindwing above 
and beneath with ill-defined pale outer band. W. China: Yaregong, type and allotype; Ta-tsien-lu, 2 <?<?; 
all in the British Museum. 
C. haasi Stgr. (Vol. 4, pi. 10 f). In the long palpus and the colouring this shows more resemblance to 
fasciaria, fatuaria or the Himalayan conjuncta Warr. than to the species between which it is placed, but the 
abdomen is not exceptionally crested. 
C. minorata Tr. (Vol. 4, pi. 10 g) ericetafa Steph. (16 b). We figure a of this British race, from Scotston 
Moor, Aberdeenshire. — norvegicola Strand (= norvegica Prout) (16 b as norvegicata). Renamed to avoid 
(secondary) homonymy with Gidaria caesiata norvegica Strand ; this change must be accepted so long as the 
unwieldy “genus” Cidarm is conserved, but as the present form was published as Perizoma it will ultimately 
revert to the name P. m. norvegica. We figure a $ of the original (Hammerfest) series. — albidella nom. nov. 
(= albida Sohn-Bethel, nec Herz). Here another homonym is created through the non-recognition of the smaller 
genera in the Cidaria group. The form, described from the Abruzzi, is said to be distinguishable by its very 
light colour and weaker markings; those of basal and distal areas commonly more or less obsolescent, even 
the median band mostly filled-in with white. 
C. perpusillaria Fernandez is unknown to me unless it can be a small, rather pointed-winged and strongly- 
marked aberration of euphrasiata, with which no comparison is made. “Antenna ciliate” (no detail). Basal
