Pantellaria was rather sharply black-marked on a clear white ground and does not seem to have been taken 

 elsewhere. — illuminata Joan, is bright brown in the basal and distal areas, well mixed with black and white illuminala. 

 chequering. Constantine, N. Africa; more or less similar forms occur also in Sicily, Spain, Portugal and 

 TenerifTe. — Larva on Cotyledon umbilicus. The pupa hibernates, often twice. Moth in the latter half of 

 May. — deverrata (Chr6t.) Dietze from Gafsa, Tunis, may probably be a distinct species. Slightly more robust, deverraia. 

 yellowish clay-colour, the transverse markings variable, the fringes not chequered, the underside almost mark- 

 ingsless. Chretien found the larva in December on Deverra scoparia; the pupa lay over till October. — 

 brunneata Stgr., from Mesopotamia, is probably also a separate species, more delicately built, clay-yellowish, hrunneata. 

 the discal dot small, the markings variable. 



E. albidulata Stgr. reminds oi oblongata (12d) or hreviculata (12m) in its white ground-colour, while its narrow alhidulala 

 brownish subbasal band and very indistinct brownish distal band seem to place it rather in the neighbourhood 

 of laquaearia (13f). White, the forewing with large black cell-dot, the markings brown, basal line indistinct, the 

 median area chiefly indicated by two dark costal spots, proximally and distally to the cell-dot; distal brownish 

 band broad, traversed by distinct, dentate white line. Hindwing with small discal dot and postmedian row of 

 small dark dashes on the veins, distal band similar to that of forewing. — Only known from the Caucasus. 



E. irritaria Stgr. is described as closely similar to irriguata (13e) but distinguished by the underside, on irritaria. 

 which the cell-mark is very indistinct, the only conspicuous marking being the broad dark distal band, traversed 

 by white subterminal line. Even on the upperside this band is better developed than in irriguata. Turkish 

 Armenia and Transcaucasia. 



E. irriguata Hhn. (= variegata Haw.) (13 e). Wings long and narrow, white, forewing with rather irriguata. 

 large black discal dot, blackish subbasal band, thick costal beginnings of the otherwise indistinct lines, and 

 dark distal area traversed by an irregular subterminal line. — eriguata Rbr. Ground-colour less pure white, eriguata. 

 markings less sharp. Figured from Andalusia, according to Dietze the prevailing form on the Middle Rhine. 

 — mauretanica Dietze is a much blackened race from Algeria, the median area in particular darker. Transitions ''P'^W^' 

 occur in Tunis and Portugal. — Larva very slender, yellow with blood-red dorsal spots. On the leaves of 

 different species of oak. Pupa strikingly slender; hibernates. Imago in April, sitting on tree-trunks. Local 

 in Central and Southern Europe. 



cosii- 

 macularia. 



E. costimacularia Leech (!3k) somewhat recalls irriguata in the markings of the forewing but the 

 resemblance is most probably superficial only. Palpus very long, as in hiltmulata. Rather larger than irriguata, 

 wings rather less elongate, tinged with very pale brown; forewing with basal patch indicated by a very short 

 line from the costa, median area as in weakly-marked irriguata, the dark markings more brown, subterminal 

 line interrupted, strongest from 2""^ median to hindmargin, here rather thick and accompanied proximally by 

 some red-brown shading, which also appears as a costal dot but is otherwise very weak. Hindwing whiter, 

 with small discal dot and strong, thick commencements of brown lines at inner margin. Japan (? Yokohama), 

 only the type ? known. 



E. despectaria Led. Wings elongate, clay yellowish, without gloss, the lines very fine, black-brown, despedaria. 

 median space broad ; antemedian line curved, postmedian bent outwards near costa, thence finely dentate ; 

 costal margin darkened at the origin of the lines; discal mark elongate, conspicuous, followed by some dark 

 scales which give the appearance of a light-centred discal spot. Hindwing paler, with blue-grey antemedian 

 and postmedian bands, which become obsolete anteriorly. cT antennal ciliation short. Altai and Hi district. 



E. staudingeri Bohatsch is larger and more robust than despectaria, otherwise similarly formed and staudingeri. 

 coloured, but rather darker. It differs in the absence of transverse markings, which are only hinted at on the 

 costa, and by the chequered median vein; discal dots very distinct, not quite so long as in despectaria. Beyrout. 



E. exiguata Hhn. (= lanceolaria Wood) (12 m). Forewing rather long and pointed, yellowish grey, exiguata. 

 with rather large, somewhat oval black discal dot; the most characteristic markings are the strong black dashes 

 on the radial and median veins where they cross the postmedian band. Larva similar to that of irriguata, 

 darker green, the red dorsal spots somewhat lozenge-shaped. On the leaves of hawthorn, blackthorn, ash, 

 barberry, Rhamnus and numerous other trees, full-fed in September or even into October. In June the moth 

 may be found resting on tree-trunks and palings or taken at night at light. Central and Northern Europe, 

 S. W France and Piedmont. 



E. exactata Stgr. Light grey or yellow grey, recalling exiguata in the abdomen and the distal area, but exactata. 

 entirely without black vein-dashes proximally to the postmedian line; Zaisan. — - modesta Dietze is a duller modesta. 

 greyish form, in some respects recalling nephelata. Aksu.
