CIDARIA. By L. B. Prout. 



aliena. C. aliena Btlr. (= tsermosaria Oh) (101 ?, as aurata) differs from corylata in having the olive bro-wn 



areas more golden brown, the dark areas blacker, but especially in the shape of the median band; the apical 

 streak is white or whitish and the 3 anterior submarginal marks are thick, commonly united into a single 

 blotch. Beneath, the forewing weakly reproduces the markings of the upper surface, the hindwing shows rather 

 strong grey dusting and 2 or 3 dark lines, not angled at the 3^'' radial like the single conspicuous dark line 

 on the underside of corylata. Somewhat variable; the ? which we figure (after OBEBTHiJR) is aberrant in 

 having distinct pale spots and lines on the median band, which is generally solid. Dharmsala, Kulu and Ta- 

 chien-lu; ? Koko-Nor; also Sikkim and Bhotan. Hampson sinks aliena to ihe following. 



aurata. C. aurata Moore (= perpulchra Btlr.) differs in its brighter golden-yellow colouring both above and 



beneath, broader space between basal and median bands, quite different shape of the latter, less darkened 

 distal area, with broad yellow apical streak, etc. The median band has its proximal margin strongly excavated 

 in the middle, its distal edge more deeply dentate. Hindwing generally greyer than in aliena. Dharmsala to 

 fulgidaria. Assam. — fulgidaria Leech is evidently nothing more than a rather deeply and brightly coloured race of aurata, 

 generally (but not invariably) with rather darker hindwing and abdomen. Perhaps even, on comparison of more 

 extensive material, it will prove to be merely a synonym. Founded on 4 beautiful specimens from Pu-tsu-fong. 



nigr%- 

 fidvaria. 



C. nigrifulvaria Hmps. (7 1). Somewhat larger than aurata, the yellow parts much darker, the large basal 

 area sharply divided by a curved, subdentate while line, the proximal part fawn-colour, the proximal excavation 

 of the median band placed in the middle of the cell (not, as in aurata, on the median vein), the distal margin 

 more clouded with black-brown. Only one specimen known, a ? from Rala, in the N. W. fiimalayas, June. 



albi- C. albipunctaria Leech (7 i). Coloration nearly as in the preceding, the brown parts rather brighter 



punctaria. (more fulvous); but chiefly distinguished by the increase of white, the lines being thickened, the postmedian 

 forming a band in the anterior part of the wing; a large pure white spot in the middle of the distal margin. 

 Hindwing whitish, darker bordered. Ta-chien-lu and Pu-tsu-fong. 



chimaka- 

 leparia. 



C. chimakaleparia Ob. (8h) differs from the preceding — which may possibly be found to be an 

 aberration of it — in the creamy white ground-colour; of the fulvous colour nothing remains excepting the 

 proximal half of the basal patch, a broad patch in the anterior half of the dark median band and a line before 

 the subterminal. Hindwing more strongly marked than in albipunctaria, having conspicuous grey lines and 

 sometimes a broad grey border. From the same localities as the preceding. 



riibidata. 



fumaia. 



C, rubidata Schiff. (10 m). A very distinct species. The peculiar arrangement of the markings of the 

 median area bears some resemblance to that of badiata but wing-shape, colouring and structure are very 

 different. In its name-typical form, rubidata is recognizable at once by the more or less red colouring between 

 the basal and antemedian and beyond the postmedian lines. Inhabits a great part of Europe, also the Issyk- 

 kul district and perhaps Brusa. — fumata Ei\ {= fumosaria H.-Sch.) is a smoky form which in large measure 

 replaces it in Asia and occurs sometimes also in Eastern Europe. Staudinger records it from the Ural, 

 Sarepta, Altai, Roumania, as an aberration in Hungary and transitional forms in N. E. Asia Minor and Trans- 

 caucasia. — Larva moderately stout, tapering anteriorly; grey-brown or reddish brown, thorax and posterior 

 segments with dark dorsal line, the intermediate segments with blackish V-shaped dorsal markings, pointing 

 forwards and enclosing small black spots in pale triangular patches ; subdorsal and lateral lines ochreous, most 

 distinct anteriorly and posteriorly; a pale ventral stripe, with interrupted grey medio-ventral line. On Galium. 

 Pupa short and stout, glossy, red-brown, with knobbed black cremaster; hibernates. The moth generally appears 

 in the following May, June or July but is rather uncertain in its appearance, not rarely passing a second 

 winter before emerging, occasionally, on the other hand, partially double-brooded. 



obscwa. 



subobscura. 



C. obscura Btlr. (= butleri Leech) was unfortunately described from a rare aberration, a large ? with 

 the forewing proximally and medially almost uniformly dark-dusted, the blackish bands being less dark than 

 usual, the centre of the median area considerably darker. Hindwing also darkened, almost unicolorous. Underside, 

 as also in the following form, ochreous brownish, the basal area of the forewing dark-suffused, both wings 

 with dark distal dot, 3 wavy dark lines beyond, then a weakly dark-divided pale band, finally a dark border 

 containing an interrupted subterminal line or row of dots. Yokohama. — ab. subobscura ab. nov. (Ilf, as 

 obscura). I propose this name for the commoner form, in which the median area is paler, with the bands 

 and postmedian line arranged nearly as in rubidata but further apart. Very near the variable Khasi race 

 fecunda Swinh. Japan (Yokohama, etc.) and W. China (Moupin). 



aridariu. ^- aridaria Leech resembles obscura in size and shape, though the costal margin of the forewing appears 



somewhat more rounded; the hindwing above is similarly infuscated. Forewing dirty yellow-greenish, the basal
