78 APLEGTA. By W. WabbE*. 



8. Genus: Aplecta Gum. 



Differs from Folia in the larger size of the insects composing it, with narrower elongate wings; 

 antennae of cf simple, or slight]}- ciliated. The larvae are hatched in autumn, hybernate half grown, and 

 feed up in spring: pupation in an earthen cocoon. 



Type A. nebulosa Hfngl. 



advena. A. advena Schiff. (19 a). Forewing pale or dark lilac grey, more or less suffused with grey brown, 



especially in costal half; a slight dark basal streak below median vein; claviform stigma outlined with 

 black: orbicular and reniform large, paler, with dark centres; reniform with white on outer edge and often 

 followed by a rufous patch; submarginal line preceded by blackish wedge-shaped marks, and acutely in- 

 dented on submedian fold; hindwing brownish fuscous; — specimens in which the glaucous tint predominates 

 nitens. are ab. nitens Haw. (19 a); — the much rarer uniformly reddish brown form is unicolor Tutt (19 a); — 

 unicoior. flavescens Spul., from the Bukowina, has the forewings pale brownish yellow; — ab. mongolica Stgr. 

 flavescens. ng^) ^he common form in central and eastern Asia is uniformly darker grey brown with a reddish under- 

 ' tone, the submarginal line equally distinctly indented. Occurs throughout Central Europe, in Britain, 

 France, Germany, N. Italy, and Russia; in Armenia, Turkestan, Siberia, Amurland. — Larva pale brown; 

 dorsal line pale; some dark oblique streaks; a whitish dark -mottled lateral line containing the spiracles 

 which are bright redbrown, edged with black; on numerous low plants. 



adjuncta. A. adjuncta Stgr. (= advena Leech nee Schiff.) (19b). Larger and broader-winged than mongolica 



Stgr., the form of advena which occurs in central Asia; pale rufous brown, more purplish in the ?; the 

 stigmata without a trace of pale outline; the submarginal line preceded by a continuous brown shade, 

 scarcely indented on submedian fold, and never marked by dark scales; all the lines and markings obscure; 

 the costal half of wing, or, at least, the cell, generally darker than the other half. China, Corea, Japan. 



tincta. A. tincta Brahm (— trimaculosa Esp., argentina Haiv.) (19 c). Forewing paler than in advena, more 



bluish grey, sometimes blue green, without dark suffusion except in median area ; stigmata as in advena, the 



orbicular pale and conspicuous; submarginal line preceded by black brown scales on both folds not forming 



wedge-shaped marks, and not indented on the submedian fold; hindwing fuscous with dark discal lunule 



obscurata. and pale postmedian line. — Coextensive in range but rarer than advena: the form obscurata Stgr. from 



hepatka. Amurland is smaller and darker; hepatica Hbn. (19 c) represents the form with blue green coloration and brown 



suffusa. suffusion; in suffusa Tutt the median area is more concisely brown than the rest of the wing. — Larva 



reddish brown, with fine dark and light mottling; dorsal line slender, white, edged with black; lateral line 



broader; head pale brown; on various low plants, such as vaccinium: also on birch. 



nebulosa. A. nebulosa Hfngl. (= thapsi Brahm, plebeia Hbn., grandis Bon) (19 c, d). Forewing white tinged 



with brownish grey; stigmata as in advena and tincta; submarginal line preceded by black wedge-shaped 

 marks, with one more conspicuous before the indentation of submedian fold; hindwing dull whitish, with 

 pallida, cellspot, veins, and a broad marginal border smoky fuscous ; — ab. pallida Tutt represents a very white form 

 bimaculosa. taken in Scotland, with many of the dark transverse markings obsolete; — birnaculosa Esp. (19 d) is the 

 robsoni. darker grey form with blacker markings; — robsoni Collins is a strong melanic form from Cheshire in the 

 asiatka. W. of England only; there are also two aberrations from E. Asia, — asiatica Stgr. (= lama Stgr.) being dull 

 askolda. grey and smaller than typical, while askolda Oberth. from Askold Island is a large brown form; — ab. 

 conspicua. conspicua nov. (19 e) is a pale brownish grey form in which the submarginal line is conspicuously black 

 and continuous throughout, even more prominently than in the ab. calabrica; the underside with the extreme 

 calabrica. outer margin and fringe prominently pale ochreous ; a single ¥ labelled simply Germany; — ab. calabrica nov. 

 (19 e) is a very large form; the forewing with pale blue-grey ground colour, irrorated and suffused with 

 dark grey in basal half (in one example all over the forewing), with all the lines and stigmata strongly 

 expressed in black and pale grey, the submarginal line in particular being continuous, black and dentate, 

 the hindwing is likewise much darker, with all the veins, the cellspot, and outer line wellmarked; a series 

 of 4 oV, 10 ??, in the Tring Museum, taken on the Sila Mts., near Botte Donata, Calabria, 800 — 1000 m, 

 July 1907, by Dr. 0. Neumann. This form reminds one somewhat of goliath Oberth. — Larva brownish 

 grey or luteous, with blackish freckles; large dark dorsal spots divided by the pale dorsal line, with short 

 black oblique stripes at the sides; spiracles black; head brownish with a dark frontal triangle: on nume- 

 rous plants. 



goliath. A. goliath Oberth. (19 d). Head, thorax, and forelegs chalk white marked with black; forewing white, 



with all the usual lines and the edges of the stigmata concisely black; a brownish smear between stigmata 

 in cell; a slight grey shade beyond outer and submarginal lines and along inner margin; hindwing dull 

 whitish, with smoky fuscous cellspot, postmedian line, veins, and marginal border. An eastern asiatic spe- 

 cies, of large size, found in E. Siberia, W. China, Japan, and Corea.
