relatively small, partly distinctly marked specimens. The illustration in the main Volume is quite good of one 
form, I am illustrating here (4 i) a further, different specimen of the 5jh With such a degree of variation it is 
difficult to give a proper description, I am therefore quoting Stattdinger’s diagnosis, which taken together 
with the illustrations, should suffice, more especially as there is no other species from Iceland, for which same 
could be mistaken: ,,m. grisea, alarum antic arum margine antico, maculis duabus fascia que exteriore albicantibus; 
antennis maris subpectinatis. Magn. 30—40 mm. d 1 ?. Var. a. alis anticis concoloribus, fuscescentibus. d$- ££ 
- Larva lives subterraneously, head with yellorv ground colour, body dull grey, a fine pale dorsal line, situate 
in a central stripe of the ground colour, laterally a wide yellow obscure longitudinal band. Hair warts strikingly 
dark. Scutellum glossy brown. Pupation at the end of June in an earthy cocoon. Pupa brown with one or two 
cremaster spines. July—August. Iceland, islandica is said, according to various authors, to occur elsewhere, 
for instance Alpheraky maintains it occurs in Turkestan, Corea and Ivamschatka, Attrivillitjs says it occurs 
in Greenland, Labrador, Livonia and Siberia. It is true that one finds specimens in those countries which cannot 
be differentiated from islanclica. Nevertheless I consider the subdivision of — rossica Stgr. to be justified. I am 
illustrating (4 i d) a specimen of rossica that has been compared with Staudinger’s original. This form is 
generally much larger than islandica , up to 43 mm, forewings and chiefly hindwings are wider and more rounded, 
the illustration in the main Volume (7 b) is not good. Saisan, Margelan and apparently the whole of Asia to 
Vladivostock. Statjdinger has separated the form of islandica from Labrador as — labradoriensis. I am illu¬ 
strating a specimen from Labrador (4 i as I consider it highly probable that a genuine subspecies occurs there. 
Ground colour pale ashy grey without a trace of brown. Outer transverse line prominent, forewings with 
distinct linrbal streaks, hindwings with distinct central lunule on underside. As already remarked islandica varies 
quite considerably and there may be genuine races among the immense material placed at my disposal. In fact 
there may be distinct species, but I content myself with mentioning the very striking form (species?) from 
LTliassutai, Aksu, Sidemi, Irkutsk, Yarkend, which I introduce as — yaikenda (A. Bang-Haas i, 1.) (4 i d type). 
It differs by the very distinct inner and outer transverse lines, as well as by the distinct pale subterminal line 
and the striking orbicular and reniform stigmata with their whitish centres. Sagittate marks distinct. The 
islandica f. nigra Sigr. most probably belongs to Icarschi Graeser. 
E. trisfis Stgr. (Vol. 3, p. 33) (4 i d)- Sec. Stgr.: „an tritici forma Darw. ?“ It is characteristic in typical 
specimens that besides the entirely differently shaped antennae to tritici, there is a segment-like long dark- 
(luna) transverse streak on underside of hindwings. Kozhantschikov deems tristis to be a subspecies of varia 
Alph. which I do not consider correct after an examination of the d genitalia, tristis is a genuine Euxoa, whilst 
varia is a typical Mesoeuxoa. Dauria, Mongolia, Siberia (Minussinsk). 
E. subconspicua Stgr. (4 k d)- In Vol. 3, p. 29 Warren places E. confusa Alph. as synonymous with 
subconspicua Stgr. This is erroneous, confusa Alph. is synonymous with squalida Gn. and should be placed in an 
entirely different Genus. It resembles a small conspicua, ground colour grey-brown, varies however considerably, 
quite dark specimens occur. Transverse lines as in conspicua, the black sagittate marks as a rule more numerous 
and more sharply marked than in that species. Hindwings dark grey-black with almost white fringes. Antennae 
less heavily pectinated than in conspicua. Palpi, legs and abdomen as in that species. In the $$ markings are 
usually more clearly marked, all transverse lines darker and more prominent. Ferghana, L T lias, Ivorla, Ili 
territory, Issyk-kul, Turkestan. July. Early stages unknown. 
E„ piingeleri Wgnr. (5 a $ type) (coll. Philipps, Cologne). Similar to subconspicua Stgr. and mustelina 
Chr. Differs from both chiefly through the darker hindwings. A black or dark streak between the reniform 
stigma and the outer transverse line seems to me to be characteristic in the $ type. Further there are 2 distinct 
black sagittate marks, which however are not very distinct in the $ type. Underside fairly uniformly yellow- 
grey with distinct discoidal lunules on both wings and a dark arched line. As on upperside a row of clearly 
defined black limbal dots before margin. Forewings yellow-brown, darker in the the transverse lines clear 
and blackish; a faint subterminal line is present; stigmata rather indistinct. Ili territory, surroundings of 
Djarkent. 
E. (?) rebel! Wgnr. (5 a d type) (coll. Philipps, Cologne). Related to mustelina Chr. Forewings clay* 
coloured, yellow brown, two dark transverse lines, a pale subterminal line with dark shaded outline on both 
sides; stigmata dark grey-brown (lead-grey), orbicular and reniform stigmata with light outline, claviform 
stigma indicated. Hindwings impure yellowish white, darker in basal area. Underside of same colour as hind¬ 
wings, these have a distinct central lunule and a diffuse shadowy band before margin. Ili territory, sur¬ 
roundings of Djarkent. 
E. muslelina Chr. (Vol. 3, p. 31, pi. 7 a). The illustration was not good, I am therefore giving same 
afresh (4 k A). Head, thorax and forewings pale grey-brown. The inner transverse line consists chiefly of minute 
blackish striations and dots, the outer one generally indistinct, often almost absent; orbicular stigma paler 
than forewing. Reniform stigma usually indistinct, the space between the two often blackish. Subterminal 
line distinct, dentate, yellowish brown. Black dots before the margin; sagittate marks often more or less present. 
Marginal line pale, yellow-grey. Hindwings of d pale, whitish, somewhat dusky at margin, rather more yellow- 
grey in $. Underside similar to cursoria. The original specimens originate from Sliakuh, Persia, quite similar
