32. Genus: Xyloiaianla Hmps. 
grisea. V. conspicillaris L. (Vol. 3, p. 88, pi. 21 g). — grisea Trautm. is a uniformly ashy grey form. — volandi 
volandi. Philipps is probably the same, perhaps somewhat paler, when it might be termed albinic. Forewings pale grey 
without white or black markings; on the other hand on hindwings the veins are more prominent and the discal 
anaiolica. spot also is deeper black than in type form. — anatolica M. Hering is an almost plain pure grey race, without 
brownish tinge or distinct markings. Thorax with dark grey hairs. From Angora. 
33. Genus: I*erigraplia Led. 
P. circumducta Led. (Vol. 3, p. 89, pi. 21 li). Specimens from E. Turkestan and also from the Amur 
pallescens. are entitled to the name: pallescens f.n. (15 f). Here the median area is quite pale olive brownish, basal 
area, markings of stigmata and marginal area are sometimes almost yellow-white. Type in the collection of 
irkuta. Pungeler in the Museum of Berlin. We are illustrating one of these specimens. — irkuta f. n. (18 g) has wider 
wings; basal and marginal areas, as well as the very large stigmata are pale sandy brown. The median area 
between same is exceedingly deep black-brown with a chestnut brown sheen. Thorax similarly pale sandy 
brownish. From Irkutsk, Sajan. 
duklana. P. duktana sp.n. (18 g) is a small species with very elongate wings. Apex of forewings much more 
protracted. Thorax, basal and inner marginal part of median area bluish ashy grey. The rest of median area 
is pale reddish brown. Stigmata also the same shape as those of circumducta and the entire marginal area is 
pale sandy buff. Stigmata are contingent and very narrowly circumscribed by black. Subbasally 2 oblique 
black streaks below the mediana. Both transverse lines indistinct, double, faintly intertilled with paler shade. 
Sub terminal line very faint and merely indicated by a few sparse black scales, shaded inwardly below costa 
with black-brown. On the margin a delicate dark undulate line. Fringes sandy brownish. Hindwings grey- 
brown with whitish fringes. From a $ from Duktan (Sarafshan); Type in the collection of Bang-Haas. 
brunnea. P • i-cinctum Schiff. (Vol. 3, p. 89, pi. 21 i). — ab. brunnea Schwing. a richer chocolate brown colour - 
vallida. ation. — ab. pallida Schwing. especially pale grey specimens. In unimaculata Schwing. the black spot between 
uni- the stigmata is absent except for 1 or 2 black dots, so that a large grey patch with black edge, is created. - 
•entraJasia'e centralasiae Bartel is much smaller, more reddish in tone, markings richer, brighter and of greater contrast, 
especially in subterminal and marginal areas. Askhabad. An illustration of the form is given (15 f). 
lionei. P. hbiiei Pglr. sugitanii Mats.) (15 f) somewhat resembles circumducta but is larger, with more 
elongate extended wings. A deep triangular black spot with fine yellow-white upper edge below the mediana 
in basal area. Stigmata very like those of circumducta, but browner and only slightly enwidened below the 
mediana. The upper end of the reniform stigma is extended upwards and outwards. The posterior transverse 
line is quite extinct, so that the brown median area is not so sharply outlined outwardly. Subterminal line is 
a very fine, yellow-white line and there are didl brown dots before same below costa, in centre and at anal 
angle. Hindwings dark grey-brown. Japan, Saghalin, Ussuri (Sutshansk). 
dlissa. P. cilissa Pglr. (15 f) varies considerably. Forewings blue-grey, about as in Antitype dubia. Stigmata 
very large, orbicular stigma with a round dot below as in i-cinctum , but it is not contingent to the reniform 
stigma and is paler grey with a tinge of yellowish. Subterminal area is similar, subterminal line with small dark 
grey, triangular streak-like marks in upper half. Hindwings grey-brown with whitish fringes and faintly indic¬ 
ated central line. From the Cilicisian Taurus. Also occurring in Asia Minor (Akshehir).
