spot is situate outwardly thereof. Between veins 3 and 5 are 2 black-brown spots on margin. Marginal band 
is wide and blackish. The yellowish fringes have a dark dividing line. South Saghalin. 
10a. Genus: Dexiadena Filipj. 
Filipjev has created this new Genus for the species — arcta Led. (Vol. 3, p. 173, pi. 41 a) and —- arctides art-tide.s. 
Stgr. (Vol. 3, p. 173, pi. 41 a) which is doubtless a genuine species. The superficial characteristics are identical arcta. 
with those of Oligia, but the genitalia differ. In Oligia the valve is hammer-shaped, here it is protracted with 
straight edge. Further the right valve is bladder-shaped with glandular formation inside and there is a brush 
of hairs on proximal edge of the 8th tergite. 
D. arcta Led. (Vol. 3, p. 173, pi. 41 a). — arctana Strd. has dusky marginal area on forewings and more 
distinct markings. Siberia, Japan, Corea. 
11. Genus: Eremobla Steph. 
E. deckerti Hmps. (Vol. 3, p. 175). The older name — pseudotrachea Krul. should be adopted for this deckerti. 
species with deckerti as synonym. A specimen from the Pungeler collection is illustrated (19 h). trachea 
12. Genus: Gerbatliotfes Warr. 
G. angusta Btl.r. (Vol. 3, p. 175, pi. 41 b). As synonym to — obscurata Warr. we have to add yokohama angusta. 
Strd. Both are translations of the diagnosis of Hampson’s “ab. 1” and are identical. obscurata. 
13. Genus: A trachea Warr. 
A. sordida Btlr. (Vol. 3, p. 176, pi. 41 c). — - sordidula Strd. has greyer ground colour of forewings and sordidula. 
postmedian area is coloured a bright rufous. — - cupreata Mats, has a coppery colouration with obsolete trans- cupreata. 
verse lines, only the anterior line is distinct and double below mediana. From Honsho (Japan). 
14. Genus: Crymodes Guen. 
C. platinea Tr. (Vol. 3, p. 176, pi. 41 d). — reisseri Bub. (19 i) is a local race from the Sierra Nevada reisseri. 
with shade of colour as zeta pernix, yellow-grey, peppered with whitish and blackish, sometimes thus with a 
tinge of greenish, all markings distinct and complete. A wide band-like central shade is particularly prominent. 
Schwingenschuss and Zerny brought back a very similar but slightly darker and more brownish form from 
the High Atlas (Morocco). — ferrea Pglr. (Vol. 3, p. 176, pi. 41 d) is not a separate species, but a smaller, less ferrea. 
strikingly marked, more grey-brownish platinea form. The illustration was unrecognisable, we are giving a 
better one of this form (19 i). 
C. mutica Chr. (Vol. 3, p. 176, pi. 41 d) is not to be recognised from the old illustration. The species mutica. 
is very close to dumetorum and we are giving a good picture of same here (19 k). 
C. dumetorum Hbn. G. (Vol. 3, p. 177, pi. 42 a) is not related to zeta , but is certainly a genuine species, dumetorum. 
The illustration was poor and we are now giving a fresh picture of this peculiar wide winged species (19 k). 
—- bleonnensis Schultz (19 k). A specimen from the Pungeler collection is now illustrated. blcon- 
nensis. 
C. bischoffii H.-S. (Vol. 3, p. 176, pi. 42 a). This illustration gives no proper representation of this bischoffii. 
handsome species. A better one is now given (19 k). It also occurs at Marash (Taurus). —- culoti Schaw. from culoti. 
Corfu is very pale, body is almost straw-yellow, transverse lines and central shade darker grey, orbicular stigma 
pale yellowish. Hindwings whitish yellow. 
C. zeta Tr. (Vol. 3, p. 176, pi. 41 e). —- zetina Stgr. should be transferred from here and placed in the 
Genus Hadula (vide p. 113 of this Supplement). — - transversata Warr. is synonymous with the older — fasciata fasciata. 
Biiren v. Salis. The illustration is rather too pale, but otherwise quite good. 
C. farinulenta Chr. was omitted from Main Volume. According to the brief description, it is most close fari- 
to zeta. The A antennae ciliate. Forewings yellow-grey, densely peppered with black-brown. Transverse lines nulenta - 
and stigmata, as well as costal spots as in zeta. It differs on underside by 2 obsolete transverse bands on fore¬ 
wings, one in centre and one before margin. Length of forewings: 18 mm. Described from Ivasikoparan. 
C. maillardi Hbn.-G. (Vol. 3, p. 177, pi. 41 f). Zerny’s view that zeta and maillardi are conspecific, does maillardi. 
not seem to be the case according to my own and Heydemann’s observations. There are differences in the 
genitalia, that would exclude the possibility of their being one species. Both occur in Albania. —- variegata variegata. 
Wehrli (19 k) are brightly marked specimens, costa and veins dusted with grey-white, transverse and sub-
