dilate. Forewings darker grey-brown, markings as the previous species. Transverse lines are absent, a black 
spot behind the reniform stigma. Hindwings brown. From West Turkestan. 
0. truculenta Led. (Vol. 3, p. 54, pi. 12 i). The illustration is not really good, though it is difficult to 
reproduce an exactly good picture. We are giving a better illustration on plate 7 b. It is a somewhat smaller 
sleeker species; frons rougher than in imp?oba, without crater; <$ antennae not crenate, however finely fasciculate; 
differs from the preceding species by the white hindwings. Apparently widely distributed in central and eastern 
Asia, recently having been discovered in the Taurus (Marash). 
0. toxostigma Hmps. (Vo!. 3, p. 54, pi. 13 a) is according to Corti’s researches to be distinguished from 
the preceding very similar species by the faintly crenate, finely fasciculate A antennae, together with the different 
characteristics mentioned in the Main Volume. Hindwings are similarly white. Also from the Taurus (Marash). 
0. turbans Stgr. (7 c). This species is anatomically distinguishable by a very pronounced, deep, pro¬ 
jecting crater on frons and the heavily dentate, fasciculate antennae. Hindwings are brown. A generally 
darker and more monotonous species than the subsequent disturbans , which Hampsox and after him also War rex 
have mistaken for turbans. 
0. disturbans Pglr. ( — turbans Hmps., nec. Stgr.) (Vol. 3, p. 35, pi. 7 f as “ turbans ") (7 b). Closely 
resembling the preceding species, but paler and more speckled. Anatomically widely different by the rough, 
protuberant frons, which is without crater and by the scarcely crenate A antennae, which are more longly 
fasciculate than celsicola. Hindwings paler brown. 
0. imitata Corti i. 1. (7 c). In regard to this species, I presume that Corti wished to describe same 
as a new species, but I could not find his notes relating to same. 
0. signifera F . (Vol. 3, p. 35, pi. 7 g). The illustration is more or less recognisable, but the basal streak 
is too thick. — ah. rubra A. B.-H. There are specimens among the south Russian signifera, which form a 
transition to improcera Stgr., with heavy brown markings on forewings. Described from Sarepta. — subsp. 
n. tauricola Corti i. 1. has also an especially intensive, bright red-brown colouration of forewings and pale 
hindwings; the inner and outer transverse lines are especially distinct and dark brown. Taurus (Marash), in 
July at an altitude of 6—900 m. 
0. exacta Stgr. (Vol. 3, p. 35, pi. 7 f). The illustration is poor, we are giving a better illustration (7b). 
0. glaucescens Chr. (Vol. 3, p. 35, pi. 12 g). As the illustration was copied from a quite unrecognisable 
picture, we are giving a fresh illustration (7 b). The species is much paler and brighter than exacta with paler 
veins. 
O. multicuspis Ev. (Vol. 3, p. 35, pi. 7 h). 
0. aequicuspis Stgr. (Vol. 3, p. 36, pi. 12 g). The illustration is unrecognisable. We are now giving a 
good illustration of this pale species (7 c). 
0. juractiniacula Chr. (Vol. 3, p. 40, pi. 12 h) belongs according to Corti, in this group and seems to be 
related to glaucescens. As the illustration in Main Volume is unrecognisable, we are giving here a good 
illustration of this fine species (7 c). 
0. sureyae Bbl. described from a single <J, is very close to the variable signifera, differing however 
by the lamellate, very long fasciculate antennae. Frons has a highly protuberant crater. Forewings short and 
wide, ashy grey, irregularly speckled and with the same markings as signifera-, reniform stigma filled with grey- 
white, it is less high and the heavily dentate white and black subterminal line is very distinct. Hindwings 
pure white and devoid of markings. Wing expanse: 30 mm. Described from Angora. 
0. caroli Culot (6 k). This and the subsequent closely related species Dr. Corti enumerates in his 
lists partly under Ogygia and partly under Fowellinia. As they doubtless are closely related, I am grouping 
them together here, caroli is described from South Russia. It is the most monotonous of the species, dull 
greyish brown without transverse lines; the black basal streak merges directly in the long claviform stigma; 
over the cell maculae with their dark centres and black circumscriptions there are small fine black costal 
marks; a lighter subterminal line can only be suspected, opposite the cell 2 sagittate marks. 
0. kaaba Obth. (6 k). The author mentions that this species is closely related to celsicola and ford- 
pula. Forewings in <$ grey-violet, darker in $, no transverse lines, with paler stigmata in a black-brown cell; 
basal streak very thick and black; claviform stigma very large; from the cell maculae a dark streak extends 
towards the margin. Hindwings pale grey, dusky at margin. Algeria (Geryville, Alfou, Djebel Aures, Lam- 
bessa, Guelt es Stel). It occurs in May and June. 
0. agrotina Rothsch, (6 h). Described as an Actinotia, it is a pretty species, fairly closely related to 
the preceding. Forewings grey with faint reddish tone, markings almost identical with those of kaaba, but
