are barely visible darker lunules. Hindwings also as dusky as forewings, no postmedian or marginal bands or 
shade. Fringes somewhat paler. Shawyr (Tannuola mountains). Type in the collection of Corti. 
P. senescens Stgr. (Vol. 3, p. 37, pi. 8 b) can best be classified next to this group, as especially its senescent. 
form semota has greatest similarity to the preceding species. The illustration in the Main Volume is not 
satisfactory and we are therefore giving a fresh illustration here (12 i). The species, about which Corti has 
published some notes, is very variable and scarcely one specimen identically resembles another. For this 
reason Corti considers the name — senilis Stgr. (12 i) for the very pale form, unnecessary, while in my opinion senilis. 
this denomination had best be retained. — semota Corti (12 k) gives one the impression of being larger and semota. 
having wider wings. The colouration is deeper leaden grey, peppered with black scales. Reniform stigma 
with blackish centre, orbicular stigma leaden grey with black scales. The central area is duskier at inner 
margin. Antennae have rather shorter pectinations than senescens, but the genitalia show no material dif¬ 
ferences. Described from Sajan. 
P. kungessi Alph. (Vol. 3, p. 37) (12 k) is possibly not a separate species, as the antennae are of kungessi. 
the same build and the genitalia are exceedingly similar, but forewings are devoid of markings and chalky 
white. Hindwings are much darker than fore wings. 
P. colorata Corti ined. (12 k). A very beautiful species, which in the arrangement of the markings closely colorata. 
resembles amatliusia and allied species. We are therefore classifying same here. Head and patagia are more 
or less white, thorax red-brown. Forewings brownish mossy green. Circumscriptions of stigmata and the 
interfilling of the double transverse lines are white. All 3 stigmata have rufous centres, the cell between 
same being blackish. In front of the postmedian, a black dentate central shade extends. Subterminal line, 
as in allied species, with similar sagittate marks anteriorly. Hindwings pure white, only narrowly brownish 
on the veins and at margin. From Thibet. Type in the collection of Corti. 
P. erschoffi Stgr. (Vol. 3, p. 41, pi. 8 1) should be classified relatively close to senescens and is perhaps erschoffi. 
best placed here. As the old illustration was unsatisfactory, we are giving a better one here (12 a). 
P. sublima Kozin, according to Corti, should be classified close to woclcei and sajana. Body and fore- sublima. 
wings pale grey, the anterior transverse line is absent, a dark grey central line forms a right angle in the 
centre of wing. The posterior transverse line is indistinct, dentate. There are minute black crescents on margin. 
Orbicular stigma is quite absent, reniform stigma consists of a diffuse dark spot, without definite outline. 
The cell is very pale grey-white in front of the reniform stigma and is cuneiform in shape with deep black 
outline. Hindwings pale grey with dark veins and lunule. Wing expanse: 33 mm. Sajan mountains.

E. prasina F. (Vol. 3, p. 60, pi. 14 a). This very variable species, of which scarcely any one specimen prasina. 
is identical with another, has so many shade variations, that besides the denominations already given in the 
Main Volume, some further names have been given. — viridior Spul. denotes the bright mossy green form, viridior. 
olivacea Lenz the yellowish bleached form. — obscura Lenz are very dark specimens, probably transitions olivaeea. 
to suffusa Tutt. — vittata Heinr. has a dark central band on forewings, that contrasts conspicuously from the 
green ground colour; — medio-nigra Lenz is probably much the same. medio- 
nigra 
E. virens Btlr. (Vol. 3, p. 60, pi. 14 a). The illustration was rather poor. A better illustration of a virens. 
specimen ex the collection of Corti is now given (14 a). 
E. magnifica Moore (Vol. 11, p. 63, pi. 8 e) was known to occur at Sikkim and the species is well magnified 
illustrated in the indo-australian Volume. It now appears to have been captured on palaearctic territory, as 
Corti enumerates same in his list. It closely resembles virens, but differs by the deep red inner margin, 
as well as the margin beyond the subterminal line. Hindwings are a deeper bronze-brown. Perhaps this is 
not a genuine species, but only a subspecies of the preceding. 
E. occulta L. (Vol. 3. p. 53, pi. 11 g) should be classified here, according to Corti, thus returning to occulta. 
the order in which it was placed by previous authors. In regard to the form — implicata Lef. (10 e) it must implicata. 
be stated that it is by no means identical with passetii. We have the opportunity of illustrating the type 
of implicata from the collection of Oberthfr. According to same this is a grey form with rather diffuse 
markings, which does not vary very much from the usual form. It- more or less corresponds to — grisea Hanne- grisea. 
mann which is a monotonous grey form. pallida Spul. denotes a paler and at the same time smaller form, pallida. 
with narrow whitish forewings without brown and with indistinct markings, almost resembling Apt. nebulosa. 
This form occurs predominantly in Esthonia. The counterpart - passettii Tli.-Mieg. denotes the black form passetii. 
with transverse lines more or less intertilled with white. It occurs everywhere among the type and has 
especially been bred by Wiesbaden collectors in some beautiful forms. — roseovirgata Dili. Just among these roseovir 
dark forms, specimens occur with a rosy suffusion in the postmedian area, occasionally in the shape of spots, , J atn
