EUXOA. By Dr. A. Cortj. 
specimens occur however also in Altai, Pontus, Hi territory, Aksu, Issyk-kul, Turkestan. The species seems to 
vary considerably in marking, it is cprite possible that there are several new species or at all events subspecies 
hidden here. Tor instance a pale form — mustaga O. B.-H. i. 1. from Yarkend is perhaps a genuine race. It mustaga. 
occurs in July. Early stages unknown. 
E. centralis Stgr. (Vol. 3, p. 31, pi. 7 a) (= nmstelina v. centralis Stgr. [obscurior, distinctius signata] centralis, 
mustela Stgr.). According to Ko zhantschikoV this is a distinct genuine species. The illustration in main 
Volume is not good, I am giving a fresh illustration (4 1 $). centralis is much more darkly and distinctly marked 
than nmstelina , the reniform stigma is generally more clearly marked, the space between orbicular and reniform 
stigmata is darker, the transverse lines distincter, double. The central shade is occasionally very pronounced 
and stands out darkly. Underside of hindwings often has a very distinct lunule. According to Kozhantschikov 
mustelina is a west central asiatic species, whilst centralis is an east central asiatic kind. But many transitions 
to mustelina are known. Issyk-kul, Hi territory, Saisan, Turkestan, according to Ko zhantschiko v also Asia 
Minor and Siberia. 
E. assymetrica Kozh. This is unknown to me. According to the author it must be classified after assymetrica. 
centralis. It is a small species, ground colour pure grey with darker grey markings. The position of the 2nd 
and 3rd transverse lines is typical for this species; the 2nd goes straight to the dorsum, the 3rd only bends 
outwards at costa, otherwise it proceeds obliquely downwards; neither of the lines is undulate, central shade 
quite pronounced, dark and almost straight. Subterminal line faintly undulate. Fringes pale grey, white on 
dark hindwings. Underside pale grey with scattered darker scales. Lunule spot quite absent on upperside, 
scarcely perceptible on underside (extract from the original description). Georgia, Kodshori, captured 
23rd August 1908. 
E„ flavogrisea sp. n. (= flav'a Corti i. 1. 4 k). The name flava was not a happy choice, as the ground flavogrisca. 
colour of forewings is a dull ashy pale colour and I am therefore revising the name. Orbicular and reniform 
stigmata are very distinct, the former sometimes very small, like a light dot. Both stigmata with dark circum¬ 
scriptions. The cell before the orbicular stigma and the space between same and the reniform stigma are more 
or less filled with brown. Costa of forewings somewhat paler. Basal line scarcely perceptible, on the other hand 
a brownish basal streak, usually there is no inner transverse line and when it is present, same is quite indistinct. 
Claviform stigma brownish. Usually the outer transverse line is also absent. There is a row of distinct sagittate 
marks. Fringes of same colour as forewings; hindwings uniformly grey-brown, somewhat paler in centre. 
Fringes white. Underside almost uniformly grey-wliite. Hindwings somewhat paler, usually with dark 
discoidal spot. Central Asia, Kara-Murun, C'hotan, Aksu. 
E. basigramma Stgr. (Vol. 3, p. 33, pi. 7 b). Varies considerably in colour; besides the reddish grey l>asi- 
form from Sarepta, from where the original specimens emanate, there are very dark to almost black forms and 
very pale, grey and blue-grey (not reddish) forms. Hindwings are sometimes in pure white, sometimes pure 
white. The orbicular stigma that is always open towards the costa, is characteristic and the black basal streak 
is always more or less distinct. Wagner has separated the blue-grey (not reddish) form with almost pure white 
hindwings as — v. pallidior. This form appears to be the predominant type in central Asia. However such pallidior. 
specimens also occur in Sarepta. — hyreana 0. B.-H. i. I. subsp. n. (5 a $ type) is a very nice race from North hyreana. 
Persia, which strikes one immediately by its sandy to reddish yellow coloured forewings. Hindwings pure white. 
The distribution of basigramma lies between S. E. —USSR., Urals, Sarepta, Thien-Shan, Issyk-kul, Ferghana, 
Tarbagatai and according to Koziiantschikov also Bokhara, S. Siberia and W. Mongolia. A specimen before 
me from the Bukowina requires confirmation as to its occurrence there. Eaidy stages unknown. 
E. (1) ptivigna Pglr. (5 b $ type). Forewings light grey without gloss, in colour somewhat like tamerlana privigna. 
Hmps. Basal streak much less distinct than in basigramma and not extending beyond the inner transverse line. 
Middle cell filled with black, stigmata pale grey, orbicular stigma elliptical, claviform stigma not visible except for 
a distinct black hook below the orbicular stigma, fringes whitish grey. Hindwings white. Underside whitish, fore¬ 
wings with small central spot and pale centre. Hindwings with quite faint central lunule. Atshan. E. Turkestan. 
E. apocrypha sp. n. (4 1 type). Similar in markings to basigramma, orbicular stigma also open towards apocrypha. 
costa, which is scarcely paler. Fore wings almost uniformly brownish grey, stigmata more or less prominent. 
The black basal streak which is characteristic of basigramma and related forms, is quite absent. Hindwings 
impure white. I have a large number of these in my collection from Naryn and a few from the Urals. Alphe- 
raky and Stattmnger consider these specimens doubtful and suppose they are variations or aberrations of 
basigramma, from the Thien-Shan territory and from Ivuldja, but without giving any reasons. 
E. inipexa Pglr. (Vol. 3, p. 29) (4 1 J 1 ). Resembles grisescens f. liyrcana Stgr., but has nothing whatever impexa. 
to do with same. Forewings a monotonous earthy grey, transverse lines clear, blackish, the inner one slightly 
arched, the outer one proceeding around the reniform stigma and touching the lower end of same, then somewhat 
obliquely to inner margin. Stigmata indistinct, fringes grey with paler basal line. Hindwings dull grey, somewhat 
darker at margin. Discoidal spot faint, elongated. Underside grey-blue with very indistinct central spots and 
diffuse dark arched line. Aksu. 
E. (?) praesaga sp. n. (4 1 <$ type). Similar to a small cos Hbn., about the size of cos f. cycladum Stgr. praesaga. 
Forewings a monotonous sandy grey with yellowish tinge. Thorax similarly. Markings faint but distinct;
