CIDARIA. By L. B. Prout. 



multipunc- C. multipunctata .S'<(/r. (9 c) also belongs to the subgenus Lampnpteryx according to the characters hero 



tata. employed, but the more slender build, thinner scaling and entirely different scheme of markings, seem to indicate 

 that there is really no near relationship. Superficially multipmictata is scarcely distinguishable from some 

 weakly-marked forms of multistrigaria Haw., the transverse lines wanting (as in the form olbiaria), the ground- 

 colour of the forewing, on the other hand, still browner (more yellow-brown) than in name-typical multistrigaria; 

 termmal dots weaker. Hindwing slightly less narrow, white-grey, almost unmarked, with brownish fringe. Un- 

 derside white-grey, very glossy, lacking the distmct discal dots of multistrigaria, postmedian line weaker. Je- 

 rusalem, December-January. The 2 is unknown and must be very sluggish or possibly wingless. 



Subgenus Asaphodes Meyr. Like Xanthorhoe but with the areole undivided. 



muscica- C. muscicapata Chr. (= nigrozonaria Leech) (9 e) somewhat resembles a diminutive ferrugata ab. uni- 



pata. (ig^ifQ,ria or quadrifasiata, but is very distinct from any other known species. The basal and median areas form 



a continuous, or almost continuous dark patch, mixed black-brown and blue-grey. Hindwing with traces of 



dark lines at the inner margin. Under surface reddish grey, indistinctly marked. Japan and S. E. Siberia, — 



ohfuscata. obfuscata Warr. (= rubridisea Warr., plumbeotincta Switih.) is on an average larger, with the dark clouding 

 of the forewing very variable but showing a tendency to leave free the posterior part of the median area, 

 extending only from base to discal dot and thence along the costal margin. Described from Sikkim but re- 

 cently recorded by Wileman from Japan. Other forms of this variable species occur in Assam, Formosa and 

 even in New Guinea. 



Subgenus Dasyuris Guen. (= Trichochlamys Hulst). Antenna in cf simple. Face- rough, 

 breast hairy. Areole double. Discocellulars not biangulate. 



Palpus and 



C. polata is referred by Meyrick to the genus Dasyuris, which was founded by Guenee on the New 

 Zealand species partheniata, and it agrees essentially therewith although the hairiness of the palpus and breast 

 are not quite so well developed. Chapman, on a study of the genitalia, unites it with the following subgenus. 

 Under the name polata are assembled 3 or 4 different forms; perhaps representing 2 or 3 separate species, 

 polata. but I have not sufficient material for a thorough investigation. — polata Dicp. (= cineraria Schoyeii) (9f) was 

 conslricta. described from "Lapland" and is the least glossy form, forewing strongly marked. — In ab. constricta Strand 

 the median band is narrower, interrupted near the hindmargin. polata inhabits Lulea Lappmark, Saltdalen 

 punctipes. and Finmark, July-August. — punctipes Curt. (=; polata Hbn., nee I)up.) is very similar but rather narrower- 

 winged, ralher more glossy, the basal and median bands rarely so solid, the white parts seldom so clear 

 white; hindwing generally with the first pale line broadened into an ill-defined band, discal dot generally small. 

 Rather strongly variable. Labrador, Baffin Land and Boothia. The palpus seems rather more hairy than in 

 brullei. the European type. — brullei Lef. (= fumidotata Walk.) is a melanotic form, iiearly unicolorous black-grey 

 with deeper black discal dot; the pale subterminal line is distinctly indicated. The fringes remain chequered, 

 light and dark. Forms a local race in Greenland; in Lapland probably it may occur as a rare aberration. — 

 hysmta. byssata Auriv. (9f) is regarded by its author as a distinct species, and I am strongly inclined to concur in 

 this opinion. Still more glossy than punctipes, greenish-grey or yellowish-grey, the median band not differentiated 

 except by the indistinct paler grey (not white) lines which bound it. Hindwing also weakly marked, usually 

 suhhyssata. with a single pale line near the distal margin. Under surface quite weakly marked. — ab. subbyssata Strand 

 has the median area constricted, otherwise like byssata. byssata is recorded from N. Scandinavia and N. E. 

 tundraeata. Siberia. — tundraeata B. Poppius, from the .peninsula of Kanin, is a modification of byssata, equally glossy 

 but with more distinct markings, ground-colour usually more strongly mixed with yellow. 



occata. C. occata Pilng. Near byssata (9 f) but larger, the forewing broader and less pointed, the hmdwing some- 



times more distinctly marked. Only known from the Saichin Mountains north of Korla, Central Asia. 



Subgenus Entephria Hbn. (= Glaucopteryx Hbn). Face without cone of scales. Areole double. Disco- 

 cellulars more or less biangulate (except in raoaria, fuscaria, cyanata, bastelbergeri, flexulata and tmcinata) 

 cT genitalia with a special organ from below the aedoeagus, conical at its base, forming a more or less long 

 stalk, termmally dilated and covered with tactile hairs. 



ignorata. C. ignorata Stgr. probably belongs to this group, as Staudinger compares it with the 2 following species 



and with polata. Expanse about 80 mm (27 by Staudinger's measurement). Forewing light grey, with quite 

 slight yellowish tinge and with sparse blackish scales; subbasal line thick, blackish; 2 or 3 faint lines between 

 this and the antemedian; antemedian tolerably distinct, sharply dentate, the median band wanting, being only 

 indicated by a slight darkening in the costal region immediately beyond this line; postmedian line very faint, 

 chiefly indicated by a row of dark dots on the veins, at the hindmargin confluent with the antemedian in a 

 small dark spot; two other lines formed of dots follow and a costal spot near the apex indicates the beginning 

 of a further dark line; marginal line consisting of sharp black strokes or dots; fringe divided by a weak dark
