25-2 ANARTA. By W. WabbSW. 



oibiculosa. 0. orbiculosa Esp. (.50 a). Forewing olive brown, tinged in parts with purplish or leaden grey; the 



lines edged with whitish tinged with flesh colour; orbicular and reniform large; the former purple black 

 ringed with pale; the latter snow white, with a purple black crescent on its inner side; submarginal line 

 zigzag, the apical area powdery white; fringe whitish; hindwing white with broad black terminal border, 

 emitting black-sealed streaks along inner margin and vein 3 and the median to base; fringe white; ab- 

 domen black ringed with white. In Europe only found in Hungary; also in Turkestan in Central Asia. 



Division III. Fore tibiae without claws; tibiae without spines; eyes hairy. 



6. Genus: Anarta Tr. 



Tongue developed; irons slightly rounded, with a small ridge beneath; palpi upturned, long-haired, 

 terminal segment pointed; antennae of ^ with tuberculate fascicles of cilia or pubescent merely; thorax 

 pectus, legs and abdomen densely haired, the last with lateral fringes of hair. Type Anarta myrtilli L. 

 A genus of small species, occurring in the polar regions or on the summits of mountains, flying in the 

 sunlight. 



Sect. I. Antennae of <J flattened, the segments laterally tuberculate, with short fascicles of cilia. 



slaudingeri. A. staudingeri Auriv. (50 b). Forewing blackish brown with some white dusting, sometimes flushed 



with olive yellow along both folds; median area darker; lines blackish, conversely edged with white scales; 

 the yellowish white submarginal line preceded by black shading; claviform stigma slight, black; the two 

 upper white with black outlines; fringe mottled; hindwing whitish, the base and inner margin grey; the 

 veins, cellspot; and outer line dark; a blackish terminal band; fringe white. Found only on the mountains 

 moeschleri. of Norway and Lapland in Europe; the form moeschleri.S^r., at present known from Labrador only, isgre} 7 er. 



richardsoni. A. richardsoni Curt. (= algida Lef., septentrionis Walk., lanuginosa Smith (50 b). Forewing pale 



grey, suffused with olive brown, most deeply in median area; lines black, the inner angulated, the outer 

 lunulate-dentate, conversely pale-edged; submarginal line defined by a row of large black w r edge-shaped 

 spots preceding it; stigmata pale grey, outlined with black; the claviform followed by a pale patch; 

 the orbicular with a dark clot, the reniform with a dark crescent, at centre; fringe mottled black and grey; 

 hindwing dull white, the base and sometimes the inner margin smoky fuscous; cellspot, veins, and outer 

 line dark; a broad blackish terminal border; fringe white. Described originally from the Canadian shores 

 dovrensis. of the Arctic Ocean; subsp. dovrensis Stgr. from the Dovrefeld Mts. in Nonvay and from Lapland has the 

 asiatica. grey markings more or less overrun with the fuscous suffusion, the hindwing smoky grey; subsp. asiatica Stgr. 

 from E. Siberia is a nearly uniform fuscous or grey brown form with the pale grej' tints absent. 



ramjnovi. A. rangnovi Pihig. Said to resemble Polia glauca, but smaller, and broader- winged ; inner line 



black outcurved in middle; outer line faint; subterminal obscure, preceded by small black dentate markings; 



claviform stigma dark; orbicular very obscure; reniform long and narrow, marked with white externally 



only; hindwing clear white, with broad deep black terminal border, grejish costa, and dark cellspot; the fringe 



- .. white. Taken flying by day in the district of Lulea, Lappmark, Norway. 



Sect. II. Antennae of $ lamellate, pubescent. 



myrtilli. A. myrtilli L. (50 b). Forewing dull dark fuscous purple, with the lines slightlj- paler; the stigmata 



obscure; a subtriangular whitish blotch on base of vein 2; hindwing orange with broad black terminal 



border; the costa and inner margin narrowly black and the base of wing often smoky blackish; this, the 



type form, occurring in Sweden, the north, of England and Scotland, and other northern localities is very 



rujescens. different from the usual bright red form, which is the ab. rufescens Tutt. (50 b); in this the forewing is a mixture 



of bright red, and olive brown or olive yellow; the transverse lines being more or less strongly whitish, 



peralbata. the stigmata red brown with pale rings, and the white spot on vein 2 distinct; ab. peralbata ab. nov. (50b) 



is an extreme form of this, in which the white lines are strongly developed,: and the central area is milk 



white from costa to inner margin, including the white blotch on vein 2; in the hindwing the yellow is 



albivena. ampler, the black of the costal, and inner margins and the basal suffusion being reduced; — ab.-albi- 



vena Haw., described from East Anglian specimens, has the forewing suffused with olive brown, -the hind- 



alpina. wing remaining normal; while in alpina Bactzer (50c), not only is the forewing olive brown, but the hindwing 



olivacea. shows only a dull yellowish median band crossed by black veins; — and again in olivacea Fwcfts the yellow 



of the hindwing is suffused with olive brown, while the coloration of the forewing remains of the normal 



nigrescens. bright red; in ab. nigrescens ab. nov. (= ab. I. Hmps.) occurring at Hyeres, S.France, the usual red suf- 



cilrina. fusion is almost entirely replaced by black; — lastly, in subsp. citrina subsp. nov. (50 c), from Cintra, Portugal, 



the whole forewing is suffused with blackish, leaving only the white blotch on vein 2 conspicuous, and 



the orange of the hindwing, both above and below, is pale lemon yellow; as the insect is decidedly larger 



than average typical myrtilli, it may prove a distinct species; at present I have seen only one- rj taken-
