I.heringi Draes. (1 c). Wings of $ and $ brown-black, semi-transparent, fringes of same colour, thorax 
and abdomen black without metallic sheen. Antennae of <$ pectinated, of $ dentated. Ta-tsien-Lu (Szechuan). 
The type illustrated is from the Dresden Museum. 
I. distinctus Kardakojf. Similar to sinensis (Vol. 2, plate 3 e) but somewhat larger, wing expanse 
29% mm in 28 mm in $. Antennae black. Thorax dull dark grey, abdomen glossy greenish in bronze 
coloured in $. Wings glossy, especially the hindwings hyaline. A faint brown dusting in costal area and at inner 
margin of forewings. Veins on both pairs of wings very distinctly dusted with rich dark brown. Fringes brown. 
A faint thin dusting partially on outermargin of fore wings. From the neighbourhood of Vladivostock at end of April. 
1. aomoriensis Mats. <$ differs according to the description from hyalina Stgr. as follows: Processes of 
antennae thicker towards the tip, somewhat shorter, rostrum yellowish; forewings narrower, discoidal cell also 
narower, subcostal and median nervures do not touch in the basal area, the long nervure is separate to the base; 
hindwings without white scaling. Resembles also psychina Oberth. (Vol. 2, plate 3 e) but has no green colouration 
of abdomen and no spine at anal clasp. Expanse 20 mm. Aomori (Honshu) in June. 
I. coreana Mats. $ resembles in shape tenuis Btb. (Vol. 2, plate 3 f) but has quite different markings 
on wings. Fore wings semi-transparent, whitish, faintly rosy-red towards the apex and somewhat pale 
yellowish towards the base, the margin, fringes, veins and spots blackish brown. Hindwings of same colour 
as forewings with whitish scales in the upper half of cell, margin, fringes and veins blackish brown. Body metallic 
bluish-green, rostrum yellow, head and thorax dark blue in the middle, legs similarly. Expanse 28 mm. Corea 
(Suigen) in April. 
!. fujisana Mats. $ and $ forewings transparent with a few black scales, the costal above the median 
nervure and the veins black, both corners of the discocellular nearly at the same level. Hindwings blackish 
brown, partly hyaline; antennae blackish-brown, in the <$ 3 joints thickened, in the ^ dentate up to the tip 
with somewhat bluish sheen. Body and legs blackish-brown with slight purple sheen. Genital organ of the 
<S covered with dense hair. Expanse 23 mm. Honshu (Mount Fuji) at end of June. 
15. Genus: Clelea Wkr. 
C. microphaea Hmps. d head, thorax and abdomen dark brown with faint purple sheen, legs and 
underside of abdomen paler brown. Wings completely dark red-brown, similarly with faint purple sheen, 
expanse 14 mm. Gensan (Corea). 
C. syriaca Hmps. d ( 1 c). Forewings completely dark reddish brown with faint coppery gloss. Hindwings 
more inclined towards grey-brown, fringes of both wings whitish except at base. Head, thorax and abdomen 
coloured as forewings, palpi paler. The type illustrated is from the British Museum. Shar-Deresy (Syria). 
16. Genus: Zjgaensi F. 
It has to be added to the general biology, that the development from egg to perfect insect rarely takes 
place without hibernation, generally once or twice and in rarer cases 3 or even 4 hibernations. For each 
hibernation a special colourless winter skin is formed, in which the larvae are unable to take solid food. The 
1st hibernation skin is generally the 3rd or 4th, the second hibernation skin may be the 5th, Oth or 7th, the 
third hibernation skin may be the 8th or 9th moult. Z. filipendulae develops fully in cases of one hibernation 
with 5 moults + winter skin, of two hibernations with 7 moults -f- 2 winter skins and of three hibernations with 7 
moults -f 3 winter skins. A repeated copulation of dd and occurs more or less frequently. Copulation of 
various species among each other is frequently mentioned in literature. I myself have a copulation of Procris 
statices d with Z. filipendulae $ in my collection, which was not dissolved even in killing. Staitder has 
described and named a large number of hybrid forms, which first should be checked and proved by breeding 
experiments. 
Note: In dealing with this Genus I have taken as a basis the newly edited catalogue of Prof. Dr. Buegeff published 
in 1926 and I have supplemented same wherever necessary by the latest literature, that was not available when the catalogue 
was issued. The complete new classification of the Zyyaena and the subdivision of the Genus into 12 Subgenera made it 
essential to enumerate again every species, subspecies or main race, as well as the varieties or races in the new classification 
in the Supplement. The addenda to Vol. 2 (p. 441 etc.) also had to be recapitulated for the same reason, not alone in order to give 
further particulars of the descriptions which were mostly only briefly sketched there, but also to ensure their inclusion in the
