CIDARIA. By L. B. Prout. 
deflorata. C. deflorata ErscJi. (12 a). We figure a $ from Transbaikal, belonging to the Tring Museum. As with 
montanata, the median band can be either entire or divided by a pale central stripe. 
rectifascia- C. rectifasciaria Led. (12 b). A long series from the Elburz Mountains, N. Persia, shows this to be variable, 
rm - especially in size and in the colour of the band; as the small specimens are mostly dated April and May, the 
large ones (none quite as large as Herrich-Schaeffer’s figure) June and July, there may probably be two 
generations, but there are some irregularities in this respect. The band shows exactly the same colour-dimorphism 
as in ferrugata, to which it is evidently more nearly related than to fluctuata, wherewith Lederer compared it. 
ferrugate/. — ab. ferrugata nov. As the name-type had the median band blackish, it is the red-banded form which requires 
a separate name; on account of the analogy mentioned above, I call it ab. ferrugata. The traversing black lines 
of the band are strong, more as in some spadicearia than in ferrugata. 
conspectaria. C. conspectaria Mann (Vol. 4. pi. 12 c) is only known definitely from Madeira. I was not quite accurate 
in saying that it was “discovered in Sicily - ’; Mann merely bred a $ on 16 November from pupae brought by 
him from Sicily and determined it as agreeing with a Madeira series in the Vienna Museum, from which — at 
least as regards the $ — his description and figures were taken. I venture to suspect, therefore, that some 
error crept in concerning the determination or the source of the pupa. 
inaequata. C. iiiaequata Warr. (Vol. 4, pi. 12 c). In addition to the range of colour-variation which was summarized 
in Vol. 4, a few <§ specimens are known in which the median band is differentiable into a paler band in the centre 
albodivisa. and a dark one on either side. — ab. albodivisa nov. (12 b) is the extreme of this development, the central part 
of the band becoming clear white. Type q from Furnas, S. Miguel, in Museum Tring. 
quadrifasia- C. quadrifasiata Cl. ( = atrofasciaria Schille, thedenii Rbl., Prout, nec Lampa). Our figure (Vol. 4, 
ta - pi. 9 d, as quadrifasciata) shows the ordinary (J-form and such forms can occur also in the $•. The latter, however, 
shows a much stronger tendency to produce specimens in which the median band is solidly black or (as Schille 
says of his atrofasciaria, a good specimen from Rytro, Galicia) “only a little lightened at costal end”. In the 
interests of exactitude, it is desirable to note that Clerck's type figure shows a large example (presumably 
O) of this black-banded form and even approaches, in the weakness of the markings of the distal area, the 
thedenii. extreme aberration thedenii ; I do not propose, however, to make any further separation. — ab. thedenii Lampa 
(= contrastaria A. Fuchs). As this name has been indiscriminately applied to all the forms with solid black median 
band, 1 give Lampa’s original description in extenso: “Median area of forewing almost black, edged distally 
by a narrow white transverse stripe; distal area brownish ochre-yellow, without markings, only the apex itself 
with grey spots and a short subterminal. Upland.” It will be seen that this is the $ of the following, which 
brunneofas- was described 32 years later. — ab. brunneofasciata F. Hoffm. “Distal area of forewing of a fine light-brown 
cu/ta. w jt,h very weak markings and scarcely perceptible subterminal line. Central band of $ almost black.” Described 
from Styria. Some entomologists may like to separate brunneofasciata and thedenii as <J-ab. and 2-ab. respect¬ 
ively; personally I do not think it necessary. See above on the sexual dimorphism of quadrifasiata. — ab. 
stenotaenia. stenotaenia Kautz is a modification of ab. thedenii with the median band strongly narrowed, only 2 mm in width, 
though retaining its distal angulation. Founded on a single example from Upper Austria, but certainly liable 
assignaria. to recur. — ab. assignaria Nitsche (~ asignaria B.-Haas, Osthelder) is not very well described, but has sub¬ 
sequently been recognized by its author to be a transition between quadrifasiata and stenotaenia, the band 
rcduplicata. less extremely narrow and less black than in the latter. The type came from Matrei, E. Tyrol. —ab. reduplicata 
Heinrich has the black median band cut into two stripes by a complete, moderately broad grey central stripe. 
tannuensis. A $ was bred from a Berlin larva. The extreme form is rare, but transitions can occur. — tannuensis Prout 
(12 b) is a dwarfed mountain race from E. Tannu-ola, N. W. Mongolia, 2500 m, the distal area and the whole 
of the hindwing and underside relatively weakly marked, otherwise varying in the same way as the name-type. 
ignobilis. — ignobilis Btlr. (12 b). Leech, who sinks this as a s y n o n y m of quadrifasiata , says of the Japanese forms 
that “some of the specimens are much suffused, others agree with the type of ignobilis Butl.“, thus allowing 
us to assume some geographical differences from the European. Rebel associates it with aberrations from 
Upper Hungary and Graz, under the diagnosis “strongly grey coloured”. It is certainly best to conserve the 
status as a race, for in the aggregate the impression is definitely of a duller, more unicolorous insect that quadri¬ 
fasiata, the white line outside the postmedian slight, the brown shades of the proximal and distal areas appar¬ 
ently never conspicuous, the blackening of the median area very seldom strong, the tendency much rather 
die tea. in the direction of the dissolutaria (Petersen ) forms, see Vol. 4, p. 226. — ab. divisa nov., which I have only 
seen well developed in a few specimens of the Japanese race, has the median band broadly bisected by a pale 
central stripe. 
/spadicearia. C. spadicearia Schiff. (Vol. 4, pi. 9 e). The distinctions between this species and ferrugata are now very 
generally understood and it is probably unnecessary to recapitulate or extend the enumeration of them. It 
may, however, be mentioned that. Fritz Hoffmann, in an excellent differentiation which had already been 
published before the appearance of our Vol. 4, gave as further recognition-marks for the larva the much darker 
ventral stripe and the much better developed black spots below the spiracles. Reference may also be made
