CIDARIA. By L. B. Prout. 



(nearly as in flamcinctaia) on the principal bands and usually on the veins distally, but especially by its dark 

 hindwing, without paler postmedian band but with distinct (though often interrupted) dentate white subterminal, 

 placed on a still darker marginal band. Pyrenees. I have specimens from a dealer labelled "Maritime Alps". 

 On an average rather larger than flamcinctaia, at least in the ?. 



infidaria. C. infidaria Lah. (9g) can be distinguished at a glance by the deep projection of the ground-colour 



into the middle of the proximal margin of the median band. The yellow scales, moreover, are differently 



distributed, being more evenly spread over the basal and median areas while in the distal area they are 



primoi-diaia.confineA to the anterior part, sometimes almost wanting. — ab. primordiata fid'teer (9 g). Darker, almost without 



nigrofasci- the yellow scales. Perhaps on an average smaller. Recorded from S. E. Switzerland and Styria. — ab. nigrofasciata 



«^''- Wagner. Median band of forewing deep black. Carinthia. — ab. flavocingulata Stgi: Forewing chalky white, 



weakly marked, the median band almost entirely pale ochre-yellow. Apparently the principal form in Baaen 



and Wurttemberg. — ab. hahnearia Gmphg., "pale greenish grey, with the median area narrow, yellow", is 



probably intermediate between flavocingulata and the name-type. — Larva similar to those of caesiata and 



flavicinctata, moss-grey, the dark edging of the red dorsal markings produced vertically as far as to the lateral 



ridge. On Saxifrage, sometimes on other low plants. Local in the mountains of Switzerland, Germany and Styria.

C. desperata Sfgr. Lhiknown to me, nearest to flaridnctata from Norway. Forewing dirty light-grey, 

 blackish dusted, with small dark basal area, broad dark median band and obsolete dark .spots before the distal 

 margin; a weak dark band closely follows the basal area and might almost be regarded as a part of it; the 

 median band is broad anteriorly, suddenly narrowed (angled) behind the cell, quite narrow at the hindmargin ; 

 its proximal edge is very weakly dentate, its distal forms 2 irregular teeth; the markings of the distal area 

 are weak. Hindwing white-grey, with traces of dark dusting towards the anal angle. Under surface very hght, 

 dirty grey-white, the median band of the forewing showing through from above. Osch, Central Asia, 1 ?. Pos- 

 sibly a smaller, more pointed-winged form of inter mediaria Alph. (I'lingeler in litt.) 



C. cyanata Hbn. (9 h). The largest of the group and easily known by its light blue-grey colouring, as 

 well as by the non-biangulate discocellulars. In the typical form the paler parts are almost white. — ab. flavo- 

 mixta Hirschke (9 h) has the pale parts of the forewing yellow. It seems to be the dominant form in the 

 Rhaetian Alps. — In ab. gottrensis Favre (9 g) the median band is considerably darkened, sometimes nearly 

 black. Described from Vallais. — The larva feeds on species of Arabis and probably hibernates rather small. 

 It is short and rather stotu, unicolorous greyish green, the tubercles small and black; in its earlier stages it 

 shows also a triangular dorsal pattern. Full-fed in May. The pupa is red-brown with pointed cremaster. Imago 

 in July, distributed in the Alps, also in the Apennines, Carpathians and extending as far as to the mountains 

 of Bosnia and Herzegovina. 



coniesiaia. ^- contestata Vorhr. and Milll.-Eutz is a doubtful form, founded on a cf and ? taken at Tanay by 



Miss de Rougejiont. Very near flavicinctata, but narrower-winged, without any yellow dusting, the ground-colour 

 bluish (much as in cyanata), the lines broad (as in caesiata), a white streak representing the beginning of the 

 subterminal line, the terminal line very indistinct. 



bastelbergeri. C. bastelbergeri Piing. resembles cyanata and flavicinctata (9 g, as flavocinctaria) but is smaller, darker and 



duller than the rornier, the median band of nearly equal breadth throughout, the antenna not so distinctly ringed; 

 from flavicinctata it differs in its rather more pointed forewing, more regularly margined central band, rather darker 

 forewing and apparently somewhat shorter antennal ciliation. Obscure light grey, veins yellow-brownish, basal 

 and median areas bluish grey, bordered by white lines, discal mark narrow, placed in a rather lighter costal 

 space; apical part more strongly grey-dusted. Hindwing whitish, from the base to beyond the middle and 

 again at the distal margin with strong grey dusting, so that only a broad postmedian band (sharply defined 

 proximally) remains white; discal dot indistinct. The terminal line of both wings is broken into black dots, 

 the whitish fringes are divided by an indistinct dark line. Discocellulars not biangulate. Genitalia not exa- 

 mined. Issyk-Kul. 



flexulata. C. flexulata (B.-Haas, M. S.) sp. nov. Possibly an Entephria. Discocellulars not appreciably angled, 



2""^ radial from their centre. Structure otherwise about as in nebnlata {9i). Distal margin very straight. White, 

 thinly scaled, the markings of the forewing grey, not very strong; basal patch about as in nebulata, subbasal 

 band narrow, very weak, median band of average breadth, narrowing posteriorly, its proximal edge blmitly angled 

 on the median, distal edge anteriorly as in cyanata, in the middle apparently excavated, weakly defined; centre 

 of the band white anteriorly, discal dot not very strong; distal area weakly marked, two dark spots at costa 

 between postmedian white band and subterminal line, shorter than those of a/facariata; marginal paired dots 

 sharply expressed; fringe weakly spotted. Hindwing white, with dark discal dot; terminal dots weaker than 

 on forewmg. Underside white, almost unmarked. Ispajran, Northern Alai, 3400 m in August. One ?, in coll.
