56 NYSSOCNEMIS. By W. Warren. 



turana. been separated by Staudinger as ab. turana Stgr., which is pale ocbreous, with the grey tinge less con- 

 intermedia, spicuous: ab. intermedia Stgr. (13 e), which is dark violaceous grey with markings obscure; ab. erubescens Stgr., 

 erubescens. \ n which the ochreous deepens into fulvqus or reddish, and the markings become distinct; and ab. funebris 

 funebns. g^ r (13 e), which is leaden grey; but erubescens and intermedia may well form a species apart, as Stau- 

 dinger himself suggested. 



oreas. R. oreas Piing. Allied to renigera, but the forewing pale sandy grey, with no dark suffusion; the 



lines and stigmata blackish and more distinct. Aksu, Mongolia. 



pudica. R. pudica Stgr. (13 f). Forewing light orange, dusted with dark; inner line swollen into spots on 



both margins and at submedian fold: outer line diffuse and waved; a distinct median shade; a costal patch 

 griseola. before the faint submarginal line; hindwing whitish, with a grey tinge; in the form griseola Stgr. the 

 orange ground colour is washed with purplish grey. — W. and E. Turkestan and Mongolia. 



umbrifera. R. umbrifera Alph. (13 f). Forewing pale brickred dusted with dark scales, the marginal third 



suffused with fuscous; stigmata undefined; the reniform a dull lunule preceded by a diffuse fuscous median 

 shade; band before submarginal line darker; hindwing dark fuscous, the basal half paler; underside of both 

 wings and the fringes pale pinky ochreous, with a broad dark fuscous marginal border. — A local species, 

 found hitherto only in Turkestan and Mongolia, easily distinguished by the underside. 



fimbriola. R. fimbriola Esp. (= maravigna Dup.) (.13 f). Forewing dark greyish ochreous, often much suffused 



with fuscous; stigmata of the ground colour, often indistinct, the upper two always separated by a fuscous 

 black blotch forming part of a thick median shade; submarginal line preceded by a blackish shade; the 

 raddei. marginal area fuscous; hindwing fuscous brown. — The ground colour of ab. raddei Chr. (13 f) is paler and 

 brighter, the dark suffusion less, and the markings clearer; the underside likewise much paler. — A south 

 European species, found in France, Spain, N. Italy, Switzerland, and Hungary; occurring also in Western 

 Asia, in Armenia, Asia Minor, Syria, Persia and W. Turkestan, these Asiatic examples being usually the 

 form raddei. Larva dark brownish grey; dorsal and subdorsal lines paler: between them on each segment 

 two oblique black streaks; similar streaks also between the subdorsal and the conspicuous dark lateral lines; 

 thoracic plate brown with 3 white streaks; head shining brown; on a variety of lowgrowing plants. 



brunnescens. R. brunnescens Hamps. (13 g). Scarcely distinguishable from canescens Btlr. from Japan and West 



China. Described by Hampson from a single cf from Hai-ning, N. China. 



praecurrens. R. praecurrens Stgr. (= bisagittata Graes.) (13 g). Much resembling praecox L. in shape and colour; 



the band before submarginal line broader and duller vinous, containing distinct black wedgeshaped markings 

 between the veins; the stigmata greenish white; the orbicular not round but, like the reniform, more figure 

 of 8-shaped, with similar dark grey centres. — Evidently a development of praecox; found at present only 

 in Amurland and Japan. 



praecox. R. praecox L. (= praeceps Schiff.) (13 g). Forewing narrow and elongate, dull pale green, dusted 



with whitish; the three stigmata ochreous concisely black-edged; orbicular round, with a rounded rufous 

 centre, reniform with a fine angled line swollen at each end; submarginal line preceded by a dull vinous 

 band; apex whitish; hindwing fuscous brown. In Northern Europe this species occurs in Britain, France, 

 Germany, Scandinavia, and Russia, also in Switzerland; and in Northern Asia in Mongolia, Amurland, and 

 flavo- Japan: — The ab. flavomaculata Graes., bluish green with the ochreous tints more yellow and the hind- 

 maculata. wrri g S muc h darke-r, is confined to the Asiatic localities, but Leech states that some Irish specimens resemble 

 it. — Larva dark or light brown or ochreous; becoming grey green laterally; lines whitish; the dorsal swollen 

 into a row of confluent blotches with darker edges; on grasses and low plants, especially on coast sandhills. 



22. Genus: IVyssocnemis Led. 



Frons smooth; all the tibiae spined, the spines fine; antennae of ri* strongly bipectinate to apex, of 

 ? also with short pectinations bearing a bristle; forewing broad. 



Type N. obesa Ev., the only species. 



obesa. N. obesa Er. (= eversmanni Led. , ledereri H.-Sch.) (13 g). Forewing purplish blackbrown; inner 



line oblique; claviform defined by black; orbicular oblique, with dark edge and centre; reniform narrow, 

 white , with red brown double centre ; submarginal line waved , ochreous , preceded by a dark shade ; hind- 

 wing yellowish white, the terminal third fuscous, beyond a dark outer line. Mainly an Asiatic species, 

 found in the Altai Mts. in W. Siberia, in E. Siberia and Amurland; also in S. Russia.
