CALOCALPE. By L. B. Prout. 199 



llioughl it iiiiglil represent an extreme development of Calocalpe tristis ab. bicolor, with nearly tlie entire 

 forewing washed over with sandy light-brown. Ta-cbien-!u. 



T. multilinearia Im'cIi (?= tremnlata Gueii.) is rather larger and much darkei- and more glossy than mulHUnea- 

 duhiosata, strongly recalling in its colour, and in the formation of the subterminal line, Philereme vashti (lie) "*' 

 but without the enlarged d^ anal clasps of Philereme and with the distal margin of the forewing leather more 

 oblique in the d' than in the ?, as in duhiosata. It cannot be confused with any other Triphosa. On the 

 forewing the alternate darker and lighter lines are almost as numerous and almost as dentate as in Calocalpe 

 undula.ta, though less striking on account of the darker colouring; the paler ones, however, are a good deal 

 dusted with whitish in places and those which bound the median ai'ea usually show more white on them, the 

 postmedian in particular bearing conspicuous white dots on the veins. Hindwing and under surface more 

 weakly marked. W. China: Ta-chien-lu and Che-tou, May to August. A ? from the Moore collection, fi-om N. 

 India also belongs here: Moore has labelled it "Scotosia tremulata Giien.. same as type." 



T. ravulata Stgr. is possibly a variety of incertata or duhiosata, distinguished by its light grey colouring, ravulata. 

 Forewing with slight suggestion of green tinge in the ground-colour, with the usual waved darker lines and 

 bands, but rather weakly expressed, and dentate whitish subterminal; the bands which bound the central area 

 possibly less strongly bent costally than in incertata; a weak dark discal dot present (wanting in incertata); 

 marginal line or dots less developed than in incertata. Hindwing feebly marked. Underside whitish grey. 

 Issyk-Kul. 



T, confusaria Leech. Wings shaped nearly as in albiplaga but slightly narrower still. Forewing dirty confiisaria. 

 white, dusted and clouded with greyish fuscous; basal patch fuscous; a narrow intermediate band fuscous; 

 antemedian band dentate-edged, but not sharply defined, touching a black discal mark; postmedian band 'darkest 

 at costa and on the veins, otherwise ill defined, its distal margin deeply indented, the indentations marked 

 with white dots on the veins; distal area dark-clouded, subterminal line interrupted, except anteriorly. Hindwing 

 whitish, darkened distally and with black terminal line; inner margin posteriorly with beginnings of dark lines. 

 Pu-tsu-fong, 3000 m, June and July. 



T. sideritaria Ob. (13 b), from Ta-chien-lu, is scarcely described, the structure not at all, and seems to have sideritaria. 

 been misidentified hitherto. According to the figure it is lighter than confiisaria, more uniformly greyish, the 

 bands weak, postmedian less deeply dentate and more regular, followed by a more complete whitish line, distal 

 area little darkened, subterminal line quite ill-defined. Possibly a Calocalpe near fasciaria Leech. 



T. moniliferaria Ob. (6 k, as monilifera). Shape approximately as in the two preceding, pattern very monilifet-a- 

 distinct. Forewing white, suffused with fleshy-brownish; basal patch and a half-band arising from middle of '"'"*■ 

 costa dark brown Generally not variable. — ab. depleta Warr., however, differs strikingly in having the depleta. 

 central band further reduced to a simple black oblique mark from the costa just before the middle, confluent 

 with the dark cell-spot. — The species is distributed in W. China in June and July. 



46. Genus: Calocalpe Hbn. 



Distinguished from the preceding genus by the presence on the cf hindwing of a strong tuft of hairs 

 — no doubt scent-hairs — which is inserted in a furrow on the under surface near the inner margin. I can 

 find no -other constant differences and am inclined to agree with Guenee and Hampson that this character is 

 only subgeneric. The areole is normally double, but in latifasciaria sometimes single. 



Early stages similar to those of Triphosa., the short, stout larva living in a domicile of spun-together leaves. 



Distribution as of Triphosa. 



C. cervinalis Scop. (= cervinata Hbn., certata Hbn) (5 i). The name-type is light brown tinged with cervinalis. 

 fawn-colour or with a somewhat more ochreous shade. Hindwing scarcely paler than forewing. Very variable 

 in colouring and even in the width of the band. — ab. griseata Bastelb. differs in the light blue-grey tone of griaeata. 

 the wings, both above and beneath. Markings as sharp as in the type form. Founded on 2 cfcf from Sprottau. — 

 ab. rubescens Rbl. has the forewing of a more uniform rust-colour, without the dark lines, but with a distinct ruhescens. 

 dark median band. Not infrequently in Ihis form the basal patch and median band are uniformly darkened, 

 forming a striking contrast to the ground-colour. — ab. infuscata Bbl. has the forewing almost uniform dark infuscata. 

 brown, the hindwing also darkened. The markings in consequence not prominent. — simplonica IVackerz. (5 i) simplonica.
