CIDARIA. By L. B. Prout. 



kezonniela- 

 ria. 



C. kezonmetaria Oh. (13 b) is aberrant in that the antenna of the cf is furnished with paired fascicles 

 of rather long cilia: the palpus is also rather long and strong. The sharply marked forewing somewhat recalls 

 lugens and semenovi, but the size is smaller, the ground-colour extremely pale yellow, not white, the markings 

 browner, much more regularly shaped. The hindwing in the cf is entirely unmarked except for the minute 

 discal dot, paired terminal dots and dark suffusion at base and inner margin. Forewing beneath with the 

 proximal markings weaker, hindwing with fine, ill-defined postmedian line and sometimes one or two other 

 similar lines proximally thereto. The only known ? has the hindwing much more strongly marked. W. China: 

 Ta-tsien-lu, Wa-ssu-kow, Tsemala and Kiala, May — June. Those from the latter localities (high mountain 

 forms, 4000—5000 m) are slightly blacker-banded and show a decided tendency toward angulation of the 

 discocellulars of the hindwing. 



trislala. C. tristata L. (:= limbosignata Nolck) (lOe). Superficially rather similar to hastata subhastata but 



smaller, the median band and the white band which follows it more angulated, subterminal line of forewing 



not forming the characteristic white mark behind the 3'''^ radial. Variable in the breadth and solidity of the 



kerteszi. central band, etc. — ab. kerteszi Aigner has the median band of the forewing almost entirely obsolete, only 



nigrata. a dark spot on the discocellulars remaining. — ab. nigrata Rhl. has the abdomen deep black, only dorsally 



continuata. with narrow white edging lo the segments. — ab. (?) continuata Fuchs is said to be paler grey-brown, both 



wings with continuous dentate subterminal line, fringes more broadly and regularly chequered with white. 



According to Fuchs this is not the true funerata (pupillata) but was formerly distributed by Staudinger under 



that name. Described from Bornich. — The larva is of moderate thickness, reddish-brown, with fine dark 



dorsal line and indistinct yellowish subdorsal but without the dorsal pattern of the ri«;ate-group; quite similar, 



except in colour, to that of galiata. On Galium. The pupa hibernates; yellowish brown with the anal point 



short. Imago in May — June with a partial 2'"' brood (cleaner white with darker markings) in August. N. and 



Central Europe, Armenia, Altai and Mongolia. 



haslidata. C. hastulata Hhn. (=: luctuata Hbn. nee Schiff.) (lOe). Extremely like tristata, on an average slightly 



smaller, ground-colour somewhat more yellowish white, the markings deeper black (in tristata, especially the 

 median band and the veins between the subterminal and terminal lines, slightly mixed with brown scales), 

 in the basal half of the hindwing well developed, subterminal line much interrupted, often nearly obsolete, 

 fringe of forewing not, or scarcely, chequered with white between the 2"*^ and S"^ radials, on the other hand 

 with the other white patches well developed (in tristata more uniformly chequered, though seldom broadly, 

 the white spots cut by a fine dark dividing-line); abdomen dorsally black, with very narrow white transverse 

 bands, whereas that of tristata (except the rare ab. nigrata) is white, with paired black spots. The underside 

 generally shows some differences, but is rather variable in both species; in tristata it is commonly more 

 yellowish white proximally than distally; in hastulata more uniform in tone throughout; in tristata the discal 

 spot of the forewing is larger and generally well separated from the other dark markings, in hastulata smaller, 



albescens, touching a dark line (the beginning of the here narrowed median band), often almost lost in it. — ab. albescens 

 Rbl. has the black distal area more or less mixed with white. I have not seen it. — Larva much more 

 sharply marked than that of tristata, with a broad continuous brown lateral stripe, dorsal area light yellow- 

 green. On Galium. The pupa hibernates and the moth appears at the same epochs as tristata, being pretty 

 regularly double-brooded. N. Italy to Roumania, also Livonia, Sweden, Armenia, Ili, Koko-Nor and E. Siberia. 



piiiriUata. C. pupillata Thnb. (= funerata Hbn.) (lOe, as funerata). Also similar to tristata, the markings brown, 



not blackish, the white postmedian band on an average rather narrower, intersected by a continuous dark 

 line, the broad distal area traversed by a regular, dentate subterminal line, a pale oblique subapical streak 

 indicated; under surface light brown, the forewing indistinctly marked from the base to the postmedian, the 

 subterminal still more strongly developed than above, tending to become connected with the distal margin by 

 pale interneural streaks. — Asiatic specimens, especially those from Thian-shan, are darker than European, 

 and in particular show more darkening on the hindwing basally and costally; they have been named var. 



orimtalis. orientalis Osthelder. — The newly hatched larva is very slender, whitish grey, becoming after 2 or 3 days 

 grey-green. Full-grown the larva much resembles that of alternata but is more elongate and not nearly so 

 reddish; olive-brown to blackish brown dorsal line on thorax and later abdominal segments deep black, first 

 5 abdominals with angled dorsal pattern ; very variable. On Galium in two generations. Pupa rather compact, 

 narrowing little posteriorly, yellow brown; hibernating. Imago on peat-moors, etc.. May and July — August; 

 very local in Europe (except the West), Central and East Asia. 



fulminala. C. fulminata Alph. (lOe) likewise belongs to the tristata group but has the ground-colour more mixed 



with yellowish brown, the antemedian line less curved proximally, the postmedian of both wings more acutely 

 produced in the middle, the underside still more strongly mixed with yellow-brown; subterminal line thick in 

 places but irregular, more or less interrupted. Abdomen as in hastnhita. Western Thian-shan and Ferghana.
