then feeding up rapidly . S.France and Spain. A variety reported from S. E. Armenia. ■ — aspersaria Btgr. (= in- oRpersaria. 

 spersaria Stgr., nee Ouen.) is narrower winged, the thorax not quite so densely hairy, less yellowish above, the 

 antemial pectinations yellowish (m lentiscaria darker). Issyk-kul and Hi district.

 nioria. 



D. leucogrammaria Piing. Robust build and wing-shape recall aspersariqi. Different from all the other Uiicagm 

 species in having distinct white lines (on forewing 2, on htndwing 1) on the brown-grey, white-dusted ground- 

 colour. Antemedian line dentate outwards on median and submedian veins. Cell-spots rather large, dark grey. 

 A schabad, second half of May. 



B. Antenna short, in $ bipectinate {Zuleika B.-Haas). 



D. nobiliaria B.-Haas may be separated at a glance from all its similarly coloured allies by the nolUiaria. 

 white or whitish costal margm of the forewing. $ considerably larger than ^. Underside in -t mo'^tly dark 

 grey, in $ rather lighter. Algeria. 



16U. Genus : Xeiiobistoii Warr. 



Apparently quite like Dyscia subgenus Zuleika, but the ^ hindtibia with terminal spurs only. Forewing 

 with 2nd subcostal connected with 3rd — 4th. Only one species. 



X. casta Warr. Whitish grey, the 2 paler, the median area of the forewing bright flesh-colour or spl- casta. 

 mon-colour. Egypt : Wady el Natron. 



161. Genus: Crocota Hbn. 



Face with tolerably appressed scales. Palpus moderate, rough-scaled. Tongue developed. Antenna in 

 (J bipectinate to apex. Femora glabrous. Forewing with distal margin entire; fovea wanting; 1st subcostal 

 from cell, connected or sometimes anastomosing with costal; 2nd from cell, usually connected with 3rd- — 4tli. 

 Hindwing with distal margin feebly sinuate between the radials. $ smaller and more pointed-winged than (J, 

 with robust abdomen. — Egg oval, smooth, shining, with very slight raised hexagonal pattern. Larva of mo- 

 derate proportions, cyluidrical, carinated laterally, without humps. Feeding on low plants and hibernating. 

 Probably the genus should be restricted to the 3 European species (all mhabitants of the mountains at elevations 

 of 1000 m. and upwards), though various others have been referred here by different authors. 



C. lutearia F. (= tinctaria Hbn.) (24 e) is distinguished by its uniform bright orange-yellow colour luiearia. 

 in both sexes. — In ab. quadripunctaria Th.-Mieg both wings have a black discal dot above and beneath, — qimdripunc- 

 Larva brownish, the dorsal line interrupted, pale-edged, dark subdorsal and lateral lines uninterrupted. On 

 low plants, hibernating. The moth is on the wing from the end of May to July, flying by day. Alps, S. 

 France, N. Italy, the Carpathians and the Ural. 



C. niveata Scop. (= illibaria Hhn.) (24 e, f). Closely related to luteana but shining whitish. Larva niveata. 

 closely similar to the following but more brightly coloured. Styria, Carinthia, Carniola, Transsylvania, ? Tyrol. 

 Flies m July. 



C. peletieraria Dup. (24 f). ^ blackish grey with blacker discal dots, $ scarcely distinguishable from peleticmrin. 

 that of niveata. The ^ genitalia show that it is not a mere race of that species, the tegumen being differently 

 shaped and the spines on the clasp collected on a decided projection, which is not the case in either of the 

 allies. Larva pale yellow-brown, rich red-brown and black, the colours arranged in longitudinal lines; dorsal 

 red-brown band with black spot in the middle of each segment, the next red-brown band black at the margin 

 of the segments, the next band wholly dark. Has been reared from the egg on Lotus and dandelion- Moth in 

 July, only known from the Pyrenees and Cantabrian Mountains. 



162. Genus: iSioiia Dup. 



Differs from Crocata in the simple ^ antenna, narrower wings, especially the long costal margin and 

 produced apical part of the hindwing, in having the 1st and the 2nd subcostals of the forewing generally 

 free and in the earlier stages. Larva rather elongate, anteriorly tapering considerably. Pupa in a spindle- 

 shaped yellow cocon, recalling that of a Zygaenid. Only one species known. 



S. lineata Scop. (= dealbata L.) (24 f). White; upperside with the veins somewhat greyish; underside llncaia. 

 with the veins more infuscated, also the folds, forewing with a large discal spot, a postmedian line usually- 

 present, at least on the forewing. Egg oval, somewhat flattened at the ends, orange, with quite shallow, irre- 

 gular pitting, only stronger at the micropylar end. Larva ochreous or brownish-grey, the markings consisting 

 of numerous irregular wavy Imes. On various low plants, hibernatmg. Moth m June, widely distributed from 

 S. W. France to S. E. Siberia.
