line, rufous whitish: hindwing luteous grey; cellspot and a faint curved median and postmedian fascia 

 fuscous. The species is known only from the 2 c?<f originally described from Transcaucasia. 



E. trifida Fiseh.-Wald. (= rogneda Stgr.). Forewing fuscous brown dusted with black; the veins, trifida. 

 except 5, all broadly whitish, interrupting the transverse shadings; stigmata black-edged, distinct; hindwing 

 white. Occurs in Spain, S. Russia and Asia Minor. 



Section II : Antennae of <f bipectinate tor - 3 ; the pectinations shorter. 



E. fatidica Hbn. (5c). Forewing reddish-grey-brown; the veins darker on grey streaks; stigmata fatidica. 

 black-edged; the claviform elongate: the other two small; the orbicular produced externally; the reniform 

 followed by dark streaks ; hindwing fuscous brown ; the ? has the wings aborted , only about half as large 

 as those of the o\ A mountain species, occurring in Europe in the Pyrenees, the Swiss Alps, the Dovre- 

 feld in Norway, and the Urals in Russia, while in Asia it is found in Mt. Caucasus in Armenia, the 

 Altai Mts. in W. Siberia, and in Mongolia. - - The larva is said by Milliere to be bluish green with darker 

 dorsum, and obscure lines; the tubercles black and single-haired; head reddish yellow marked with black, 

 the thoracic shield black ; feeding on grasses. - The form occurring in Siberia and Mongolia , known as 

 ab. bombycia Eversm. is much darker, the wings clouded with blackish brown, obscuring the markings. bombycia. 



E. sabulosa Ramb. (12a). Forewing brownish grey, the veins blackish; a blackish blotch before sabulosa. 

 margin above middle: a black streak from base, more irregular than in endogaea Bsd.; claviform large, 

 black: orbicular and reniform both black with grey rings: the cell black between them; hindwing pure 

 white. — Recorded from Andalusia only; it resembles the common exclqmationis , but has longer antennal 

 pectinations. 



E. chretieni Dumont (5d). Forewing uniform dark ash-grey; the costa narrowly darker; claviform chretieni. 

 stigma narrow, black, contiuning a black streak from base; orbicular all but obsolete; reniform irregularly 

 diamond-shaped, with a black dash before and beyond it; veins finely black, with cloudy fuscous intervals; 

 hindwing pale brownish fuscous ; antennae blackish. Recorded only from Gataluna, La Granja, Spain. 



E. bifurca Stgr. Much like a small dull obesa, but with both costa and inner margin darker; the bifurca. 

 median vein black on a broad white streak, forked outwardly: antennae less strongly pectinated. One of 

 the smaller species, described from a single & from Saisan. 



E. segetum Schiff. (— praecox Hbn., nee L., fervida Hbn., sicula Bsd., dimidia Zell., sicania Gum., segetum. 

 certificata Wlk., ingrata Btlr., fucosa Btlr.) (5d). Forewing typically clear reddish brown, the lines and 

 stigmata distinct; costa and outer margin sometimes blackish; hindwing shining white, with veins and 

 margin dark; $ darker, sometimes black, with all the markings obscured. Abundant throughout Europe, 

 Asia and Africa, occurring in the temperate regions from June to August. - - ab. pallida Stgr. (5d, e), pallida. 

 smaller than the type, has the ground colour whitish-grey, with less defined markings, and occurs, like 

 many other pale forms, in the regions of Central Asia and Amurland. Butler's types of ingrata and fncosu 

 are both from Japan, and Walker's of certificata from N. China; other types are from extra-palaearctic 

 localities. Of this very variable species no less than 12 aberrations have been described or figured by 

 European and British Authors. — ab. segetis Hbn, has the forewing grey with the costa broadly black- segetis. 

 brown : - ab. caliginosa Esp. (= segetum Hbn., nee Schiff., sordida Haw.) is redbrown, like typical segetum, caliginosa. 

 but much clouded with blackish , especially on outer margin ; — while ab. fuscosa Esp. is pale grey with fuscosa. 

 a slight redbrown tinge and blackish outer margin; — ab. catenatUS Haw. is a whitish grey insect, with catenatus. 

 outer line monili-form, touching the reniform, the marginal spots confluent into a line; — ab. pectinatus pectinatus. 

 Haw. resembles the preceding, but the claviform stigma is very small and the outer line lunulate dentate; — 

 ab. spinulus Hair, has the outer line excurved round the reniform, not touching it and an obsolete row of spinulus. 

 pale spots before outer margin; — in ab. connexus Haw. the upper stigmata are united by a double line connexus. 

 and the acute claviform emits a line to outer margin; — ab. corticcus (recte corticeus) Haiv. has the corticeus. 

 orbicular tridentate instead of round and the transverse lines obsolete; — ab. venosus Haw. is distinguished venosus. 

 by the veins being broadly fuscous; — ab. monileus Haw. has the pale grey ground dusted and clouded monileus. 

 with black; — ab. subatratus Haw. is blackish with the outer line represented by a row of pale dots; and subatratus. 

 lastly ab. nigricornis Vill. (= nigricornutus Haw.) is entirely black in forewing, with the antennae also nigricomis. 

 black: as a rule, the dark forms are $?. — Larva greyish ochreous with the lines dark-edged; head and 

 thoracic plate pale brown; on roots of low plants, often very destructive. 



E. robusta Eversm. (= trifurca H.-Sch, non Eversm.) (5e). Forewing dark redbrown; base of costa robusta. 

 blackish : veins dark on pale streaks ; stigmata with black outlines ; the claviform elongate ; the orbicular 

 large and round: submarginal line dentate, grey, preceded hy dentate black markings; hindwing fuscous 

 brown. — From the Ural Mts. in Russia, the Altai Mts. in W. Siberia, and from Mongolia; a large 

 robust species.
