1. Genus: Tliyris Lasp. 
T fenestrella Scop. (Vol. 2, p. 371, pi. 50 e). As mentioned in the Main Volume specimens from southern 
Europe have smaller vitreous spots. Of such specimens the paler Spanish form nevadae Oberth.w as already 
discussed in Vol 2 In contrast to same a race flies in Italy (Genoa, Modena, Capri) named: nigra 0. B.-H. nigra. 
(16 b) which is very dark, almost black. The coppery spots and dots are entirely absent, the fringes and legs 
are also almost entirely black. Specimens also occur in Mesopotamia in which the hyaline spots are somewhat 
smaller, the other markings scarcely vary from german specimens. A somewhat larger form seems to occur 
at Ta-tsien-lu. 
3. Genus: I>ysodin Clem. 
D iqnita WJcr The variability of this species was mentioned in Vol. 2, p. 372 and a few of the more 
common forms were mentioned as synonyma. Amongst them also siculoides Fldr. (16 a), which is enumerated siculoides. 
in the indian part of this work (Vol. 10, p. 744). As latterly denominations are recognised for quite insignificant 
subforms, we are giving an illustration of siculoides here (16 a). According to Pagenstecher the outstanding 
feature of this form is the absence of the hyaline spot on forewings. As this also occurs m specimens taken 
at Kashmir, this form is thus found on palaearctic territoiy. 
7. Genus: Striglina Gn. 
St. fixseni Alph. This species was described in 1897 from a pair captured in Corea. Since that time fi.iscni. 
only 1 further $ appears to have been caught by Leech. Ground colour agrees with that of scitaria WJcr. dealt 
with in Vol 9 p 373 pi 50 f The marking of the lines however varies considerably. The line in scitaria that 
traverses the wings is much more steeply oblique. Besides this a further line occurs posteriorly, which commences 
at costa slightly before the other line, circumvents same in an arc and then proceeds approximately parallel 
to the outer margin not extending however as far as the inner margin. On hindwings the chief line, that corres¬ 
ponds to that of scitaria, is angulated outwards in the centre of the wing. The second line runs parallel to same 
about in the middle of the outer area. 26 32 mm. 
9. Genus: Itlioclonciirsi Gn. 
Rh. parallelina Leech. pale cinnamon brown, $ somewhat darker. Markings the same m both sexes, parallehna 
Wings with dark brown striations. On forewings two approximately parallel black transverse lines traverse 
the centre. The first is angulated below costa. The second is conjoined to costa by a short black line Ano ler 
line proceeds from costa near apex to the middle of outer margin. On hindwings there is a curved black inner 
line and a fine line corresponding to the apical line of forewings. 30—32 mm. Central C hina, 
Genus: Camptocliilus Hmps. 
This Genus is dealt with in Vol. 10, p. 768. A species is now classified here that originally was described 
as Pyrinioides Btlr., then placed by Hampson to the Genus Rhodoneura and finally again described by V akren 
as Gamptochilus. , .. ... £ . i . 
C aurea Btlr (= divergens Warr., schedeli Gaede) (16 a). Ground colour orange-yellow with fine dark aurea. 
brown striations. A double line proceeds from three quarters of costa of forewings to centre of inner margin 
and from the same spot two further lines originate, one proceeding to anal angle and the othei to e
