CIDARIA. By L. B. Prout. 243 



C. lasithiotica Rbl is also closely related to berberata, doublfully distinct. It may be known by the lasithiotica. 

 entire absence of reddish in the coloration of the forewing and the more complete markings. The transverse 

 stripes are blackish brown (not red-brown), the antemedian broad, more strongly sinuous, the light median 

 area itself narrower, its distal boundary more sharply expressed; the white subterminal line is very distinct, 

 its proximal dark edging towards the costa not united with the black apical streak; the fringes are sharply 

 dark spotted at the extremities of the veins. The hindwing sometimes shows a distinct waved white subterminal 

 line. The under surface is also more sharply marked than in berberata. lasithiotica was discovered in the 

 mountains of Crete. Specimens from Granada (June, August) seem still nearer berberata. 



C. berberata Schiff. (lOm). Easy to distinguish by the form of the postmedian, the rather long, in berberata. 

 part thickened but somewhat interrupted apical streak, etc., coloration more brown than in the two preceding. 

 Underside rather pale, forewing with subbasal costal spot usually very conspicuous, both wings with discal 

 dot and postmedian line, the latter most distinctly marked on the veins. cT antennal ciliation very short. — 

 ab. elutata Favre is a washed-out form in which the median area is represented by two lines which meet at elutata. 

 the costa, the postmedian then describing a circle, a sinus and finally some undulations. "Here and there among 

 the type" (Favre). I have seen nothing like it. — Ab. semifasciata ab. nov. is a very remarkable form in semifas- 

 which the median area of the forewing in much narrowed and in its anterior part contains a narrow dark ciata. 

 band, which posteriorly becomes reduced to a mere line. Figured by Barrett, Lep. Brit. Isl. vol. 8, pi. 344, 

 f. 2. — ab. hellwegeri Bbl. has the median area unicolorous black-brown. — ab. schultziaria Heider has the hellwegerl 

 ground-colour of the forewing uniform brown, the median area not paler; hindwing also darkened. — Larva shovi, schultziaria. 

 stout and rugose, with raised transverse skin-folds and well developed tubercles; variable in colour, some 

 shade of grey or brown, sometimes with whitish lateral spots ; fine longitudinal black lines and dark transverse 

 stripes. On Berberis vulgaris. The pupa is short and stout, yellowish-brown, with short knobbed cremaster. 

 The moth appears in two generations, in May and August, and is widely distributed in Central-Europe, Asia 

 Minor, Transcaucasia, the Altai, etc. 



C. consanguinea Btlr. (= directaria Graes.) represents berberata in Japan and Amurland. It is more consangui- 

 uniform reddish grey, the subbasal and antemedian lines straight, oblique, parallel, rather nearer together than '2««- 

 in berberata, the median area not or scarcely lighter in its central part than the rest of the ground-colour, the 

 subterminal line wanting. 



C. derivata Schiff. {= nigrofasciaria Goeze, separata Thnbg.) (10 m) differs from all the other species derivata. 

 in the extraordinarily strong projection of the outermost line of the median area. The markings are well shown 

 in our figure. — ab. ludovicata Mill, has almost the entire median area darkened so as to form a central band. — ludovicata. 

 Larva long and slender; head small, flattened, purple-red; body bright green with purple-red dorsal line on 

 thorax and last 3 segments; legs purple-red. On wild rose. May — July. Pupa slender, red-brown with the 

 wings more green, hibernating in an earthen cocoon. The moth appears in April and May and inhabits Central 

 Europe, Russia, Transcaucasia, Altai, the Hi district, etc. 



C. querulata Pilng. is smaller and narrower-winged than derivata, greyer and more uniform in tone, querulata. 

 with less irregular postmedian line; the latter rather recalls that of the berberata group but querulata lacks 

 the dark apical streak which is present in that group. Forewing ash-grey tinged with brownish, median area 

 broad, subterminal line only indicated at costa, terminal fine, fringe dark-chequered. Hindwing greyish, some- 

 what darker distally, postmedian line not so deeply angulated as in derivata. Both wings beneath with fine 

 discal dot and postmedian line; forewing with a small dark spot near base of costa. Korla. 



C. alhambrata Stgr. (10 m) is again easy to recognize on account of its small size, relatively long costal alhambrata. 

 margins, straight distal margin of forewing, nearly straight subterminal line, etc. Under surface weakly marked. 

 Granada and Murcia, September — October, also in larger examples from Algeria. 



C. adlata Stgr. (9i). Affinities uncertain, possibly near the preceding. A black apical streak is not adlata. 

 shown in our figure. & antenna subdentate; discocellulars weakly biangulate. cf genitalia almost as in the 

 first subgenera of Cidaria. Underside with small discal dots and a slight subapical darkening at costa, other- 

 wise very weakly marked. Syria and Palestine. 



C. sagittata F. (= bidentata Hufn. nee L., comiiaisi Hbn. nee L.) (10 m). Forewing bright fawn-brown sagittata. 

 with rather narrow, white margined basal and median bands, the latter with extraordinarily strong distal pro- 

 jection in the middle, which at once characterizes the species; a white longitudinal streak follows the projection 

 at the distal margin. — ab. interrupta Hirschke, with the median band interrupted with white at the fold, is intemipta. 

 the only known aberration. — Larva short and stout, light green with strong dark green transverse ridges 

 and interrupted lateral line. On seeds of Thahctrum. Pupa short and thick, green; hibernating. Local in 

 Central and Eastern Europe and in S. E. Siberia and Japan, flying in June and July.
