CI D ARIA. By L, B. Prout. 



stout, greenish, the anterior part and wings sometimes ochreous. didijmata is abundant in most parts of 

 Northern and Central Europe; further south and east it seems to be confined to the mountains — Pyrenees, 

 Alps, Ural. It is on the wing in July and part of August. 



icterica. C. icterica Djakonov agrees in structure with didymata except in the cf genitalia. Deep ochreous, about 



as in Pti/cJiojwda serpenfata (4 a), rather variable in colour, the ? in general lighter than the cf . Forewing with 

 8 brown lines, the 2 which limit the median area the most distinct, the area itself not or little darkened, basal 

 not darkened; discal dot sometimes obsolete; distal area much darkened, always with distinct light sublerminal. 

 Hindwing light ochreous, in strongly marked examples with 4 lines and darkened distal area. From 2 or 3 

 localities in the province of Semiretshje. I have not seen it. 



corydalaria. ^- corydalaria Graes. (10 e) is very distinct from all the preceding species of the group in its scheme 



of coloration, which rather recalls the Eulype and Epirrhoe groups; discocellulars of the hindwing only weakly 

 biangulate. The antennal pectinations are rather long, widely separated. The name-typical form, from the 

 Amur and Ussuri district (perhaps also froui the Black Sea Government), has the white markings conspicuous; 



bogumilaria.m particular the postmedian band, especially on the forewing, is broad and uninterrupted. — bogumilaria 7?6/. 

 is a European representative with the white median band more or less strongly reduced and interrupted, the 

 antemedian line and the distal white spots on the contrary somewhat extended. Croatia and N. Bosnia — 



eurytaenia. eurytaenia i?5/. (10 f) has the white markings wider than in hogumilaria, especially the postmedian band on both 

 -wings, yet this does not assume the same width as in the Asiatic form, while the aiUemedian white markings 

 of the forewing remain as conspicuous as (or even more conspicuous than) in hogumilaria. S. E, Bosnia. Flies 

 in July and August. 



hellaria. C. bellaria Leech (Ik) agrees with corydalaria in structure and is perhaps nothing more than a further 



race of it, characterized by the strong reduction of the black markings in the proximal half of both wings. 

 W. China: Ta-chien-lu, Ni-tou and Chang-yang. 



■pendearia. C. pendearia Oh. {■= moupinata Pouj) (13 d). The affinities of this and the remaining species of the 



group are somewhat uncertain, but they agree with the subgeneric characters here given, pendearia is charac- 

 terized by its rather broad median area which does not narrow at all (but indeed usually appreciably -widens) 

 posteriorly, otherwise it is marked rather like correlata, but the wings are differently shaped, the size larger, 

 the centre of the median area grey, not whitish, the hindwing more suffused, with postmedian line strongly 

 marked on the veins. W. China, June-August. 



gralaria. 



C. grataria Leech (llh) is a broad-winged species, the hindwing slightly angulated at the 2"'' subcostal, 

 thence with the margin gently undulate, palpus rather long, & antenna fully pectinated. Warren founded for 

 it a genus Amoebotricha, placing here also the following species {correlata). Japan: Nikko, Oiwake, Nagasaki, 

 September — October and even as late, in the last-named locality, as the beginning of December. 



correlata. C. correlata Warr. {= badiata Leech nee Schiff.) does not seem to me very closely related to the 



preceding. Rather smaller, the antennal pectinatioiis shorter, the hindwing rather more produced at apex, its distal 

 margin more crenulate, forewing without the large triangular costal marks. Altogether closely similar to hadiata 

 (10m), except in the pectinate cf antenna. Whitish grey, the hindwing whiter ; markings nearly as inhadiata. Gifu. 



B . Antennal pectinations extremely short, with dense, short c i I i a t i o n. 



parallelo- 

 lineata. 



infuscata. 



C. parallelolineata Retz. {■= vespertaria Schiff. nee L., parallelaria Vill. nee Schiff, sudduplicaria 

 Costa) (9 d). Quite distinct' in appearance, as well as in structure, the lines of the forewing parallel, rather 

 straight, apical black dash only represented in the fringe and in an enlargement of the first of a series of 

 subterminal dark dots. The ? is whiter than the d'. Underside, especially in cf, browner, both wings with 

 discal dot and two lines beyond it, all usually distinct. — ab. infuscata Rhl. has the forewing, the distal area 

 of the hindwing and the entire underside strongly darkened with sooty brown. — The egg hibernates. Larva 

 rather slender, green, head light brown, dorsal line fine, dark. It feeds on vaiions low plants in May and June. 

 Pupa rather compact, yellowish brown, the margins of the segments dotted, the cremaster short with the hooks 

 divergent. The moth flies in August and September in the mountain districts of Central-Europe and extending 

 eastward to the Altai. 



Subgenus Psgchophora Kirhij (= Scinneria Dijai). Differs from Xanthorhoe in the rather smaller eye, 

 hairy palpus, commonly exserted cf genitalia and frequently in having tlie areole undivided. 



frigidaria. C. frigidaria Ghoi. (9 a). Recognizable by tlie narrow wings, the forewing triangular with rather. acute apex, 



the hindwmg also produced towards the apex, but rounded, and especially by the structural characters. The
