284 TARACHE. By W. Warren. 



the outer and subterminal more or less complete, sometimes interrupted; two black spots represent the stigmata; 

 fringe yellow marked with black in middle and at each end; hindwing reddish fuscous; the fringe yellowish 

 white. The insect varies according to the preponderance of the yellow or black scaling; as a rule, the yellow 

 nigra, prevails in the $, the black in the $; — the ab. nigra Ersch. (52 g), from W. Turkestan, is almost wholly black. 

 The species occurs throughout Europe and Central Asia to Japan and China ; also in Afghanistan and Beluchistan. 

 The imago takes short jerky flights in the sunshine close to the ground and is difficult of observation; it fre- 

 quents dry and sandy localities. Larva green changing to brownish; dorsal and subdorsal lines darker, with 

 faintly paler edges; spiracular line broadly pale yellow; feeding on Convolvulus in late summer. 



viridi- E. viridisquama Guen. (52 h). Forewing black brown, clothed with long pale green scales in basal 



squama. an( j inec |j an areas; the lines represented by oblique pale costal striae; the subterminal line greenish, indistinct; 



some green scales along termen ; fringe black brown with pale patches above and below middle ; renif orm stigma 



obscurely ringed with whitish; hindwing black brown with a bronzy tinge; fringe tipped with white. A local 



obscura. species found only in Spain and the Pyrenees. Like trabealis this species also has a dark form ab. obscura ab. 



nov., in which the greenish scales are reduced to a few long yellow ones towards base of wing. 



deleta. E. deleta Stgr. (52 g). Forewing olive ochreous; the markings faint, interrupted, brownish; lines repre- 



sented by costal spots; orbicular and renif orm stigmata small and round; more or less developed horizontal 

 algira. streaks from base below cell and above inner margin ; hindwing ochreous with slight brown suffusion; — inalgira 

 flavonitens. Oberth. (52 h) the dark markings are black and conspicuous, especially the outer line; on the other hand in flavo- 

 nitens Aust. (52 g) the markings tend to become obsolete, being faintly olive on a yellow ground. Biskra, Algeria. 



fascialis. E. fascialis Hmps. (52 h). Forewing greyish rufous; a pale yellow streak along costal area, leaving 



the extreme edge rufous, narrowing to base and pointed before apex, swollen at end of cell, enclosing the 

 small rufous orbicular stigma and emitting a spur below the round renif orm ; a shorter yellow streak on basal half 

 of vein 1; an obscure oblique purplish grey outer band from vein 6 to inner margin; a yellow line close before 

 termen; hindwing reddish brown; fringe brown with pale tips. Found in Kashmir, in the Scind and Goorais 



deflavata. Vallies ; in the ab. deflavata ab. nov. the yellow is wholly absent from the forewing and thorax. 



38. Genus: Tarache Hbn. 



Tongue fully developed ; frons with a rounded prominence more or less roughened at middle with a cor- 

 neous plate below it; palpi porrect, the second segment fringed with scales below, the third short and smooth; 

 antennae of $ simple, lamellate ; thorax and abdomen smoothly scaled, without crests ; forewing with normal neur- 

 ation; veins 3, 4 of hindwing sometimes from cell, sometimes stalked; the costal and subcostal veins 

 anastomosing to near middle of cell. Larva in autumn on low plants; in warmer climates with an additional 

 summer brood. The imago, as in Erastria, flies in the sunshine. The sexes often differ considerably. Type T. 

 caffraria Cram. 



Sect. 1. Veins 3, 4 of hindwing stalked. 



rufidncta. T. ruficincta Hmps. (52 h). Forewing glossy yellowish white; a rufous band along termen, widest at 



middle, and not reaching below submedian fold; fringe rufous, paler at anal angle; hindwing pale yellow; a red- 

 dish brown band along termen, its inner edge diffuse; fringe yellowish white; in the $ the costal half of 

 hindwing is dusted with brown both above and below, and a cellspot is present. Atbara, Abyssinia. 



marmoralis. T. marmoralis F. (= tropica Guen., maculosa Walk., bipunctata Walk.) (52 h). Forewing yellowish 



white from base nearly to middle of inner margin, on costa reaching nearly to apex; the terminal area olive brown, 

 suffused inwardly with purplish, the termen itself again yellowish white; an inner olive ochreous band, inter- 

 rupted in cell and oblique below it; outer line olive ochreous towards costa, more rufous below; subterminal 

 line yellowish white; a terminal row of black spots; fringe yellowish white with black blotch above middle, 

 and black scales at apex and tornus; the stigmata small, grey, their centres white, the orbicular round, the reni- 

 form oval; hindwing ochreous white, the termen from apex to vein 2 tinged with red brown; the $ is much 

 paler, more whitish, than the <$ ; the markings without or with only slight olive tinge ; hindwing with the terminal 

 dark band broader and reaching tornus. This species, which is common in India and the islands is recorded 

 from Upper Egypt and from China, whence Walker's type of maculosa; Guenee's tropica was described from 

 Java. Larva grey, with diffuse purplish bands at middle of each segment, and many irregular yellowish white 

 spots defined by purplish brown, forming a double dorsal line and segmental bands; head rufous with black 

 mouth; the legs black. 



bicolora. T. bicolora Leech Forewing black overspread with olive yellow, extending on costa to near apex and 



on inner margin to middle; the terminal area red brown inwardly suffused with purplish; the inner edge of 

 the dark outer area bent inwards at vein 6 to end of cell; the outer and subterminal lines marked only by the
