Addenda: ZYGAENA. By H. Reiss. 
The fraxini population from the neighbourhood of Manglis, west of Tiflis, according to a $ before 
me ex the collection of Staudinger, has distinctly separated spots 5 and 6 of forewings, margins of hind- 
wings are decidedly narrower. Romanoff also mentions, as localities for Z. fraxini: Borjom, S. E. of Kutai, 
Kasikoparan in Armenia (of these 1 specimen is ab. scovitzii) and Derbent, N. W. Baku on the coast. I 
have not been able to obtain definite confirmation of these localities. 
5. sogdiana Group. 
sogcliana. Z. sogdiana Ersch. (= scovitzii Rbl.). I lie races of sogdiana differ in the main from the previous 
two groups by the red collar and red abdominal belt in both sexes, otherwise they have great similarity with 
the fraxini group. The occurrence of the red collar forces me to separate sogdiana from fraxini, for this is an 
analogous case to carniolica and fausta, which are also separated. 
The types of sogdiana were captured end of May near the town of Tashkent. Antennae, head and body 
are black with deep red collar and fairly wide abdominal belt of the same shade. Ground colour of forewings 
is black with scarcely discernible green sheen, with six deep red spots, which are or more less surrounded with 
yellowish white and are situate about as in fraxini-, hindwings are deep crimson red with wide black mar¬ 
gins. On underside colouration and marking is as on upperside, only the spots of forewing have scarcely any 
yellowish white surround. A $ from Tashkent, sent to me by Sheljitzhko, has additionally reddish scapulae 
and also that part of the head between the eyes is distinctly red. The abdominal belt in this specimen is 
laterally enwidenecl, covering 4 segments. Fringes are bluish black and this specimen therefore cannot at 
present be held to belong to the erschoffi group. This $ and a $ of sogdiana from Tashkent, also from the 
collection of Sheljuzhko, are being illustrated (16 1). 
Specimens labelled “Tura as locality, differ from the type race. Bltrgeff also mentions these trans- 
caspian specimens having normal spot markings, which are inclined to be carmine red and an abdominal 
belt covering one or two segments. Further there seems a tendency to the formation of a transverse band 
on hindwings, the black margin bulging widely upwards, almost forming a streak towards the centre of the 
wmg from about the middle of the lower margin. From the costa of the hindwings some appressed black 
scales generally project towards this streak. Without however having exact particulars as to locality, these 
transcaspian specimens lose in value and are difficult to classify. Meanwhile they can be placed with the 
subsequent race ( margelanensis ) until the racial charateristics can be ascertained from a sufficiently uniform 
and numeious quantity of specimens. It seems to me as if in the higher altitudes of the mountains of 
Transcaspia, populations may occur like separata Stgr., and that the specimens so far submitted to me 
originate from the lower altitudes. For instance I was able to discern separata characteristics in a $ sent 
to me from the mountains around Samarkand. 
Around Margelan (type race) and Namangan, at lower altitudes near Osh in Ferghana, a race occurs: 
margela - subsp. margelanensis Reiss (= sogdiana Stgr.) of which Staudinger already had a large number. It always 
has a double, attached carmine-rose apical spot (5 and 6) on forewings, which is generally almost completely 
and widely encircled by yellowish white. Also spots 1 and 2 are edged outwardly with yellowish white, 
whilst 3 and 4 are boldly encircled. Abdomen has a carmine-red belt, generally covering 2 segments. The 
specimens that were used for illustration in Vol. 2, pi. 7 e and denoted scovitzii, probably originated from 
Margelan or Osh and belong to this race. 
p. 22, line 21 from top. The subsp. separata Stgr. seems to only occur in fairly high altitudes, for 
instance at Usgent (type race) and Goultsha, further at higher altitudes around Osh and in the Alexander 
mountains. In these the apical spot (5 and 6) is generally separated into 2 single spots, of which the upper 
(5) is the larger and roundish, whilst the outer and lower (6) is elongate and sometimes quite rudimentary. 
Further separata has a much wider black margin to hindwings, which expands in its centre inwardly in a 
black dentation. The ab. ornata Bgff. (p. 22, 16 1) described from a specimen from Turkestan, occurring among 
separata is not rare and Staudinger had already observed same without giving a special denomination. I 
am illustrating one of the original separata specimens ex the Staudinger collection and which shows at 
the same time the characteristics of ornata Bgff. (16 1). A further distinguishing feature of separata is the 
inclination towards the suppression of the red abdominal belt. In some specimens it is quite absent, in others 
it is only rudimentary, but always only faintly present. On the other hand the red collar becomes more 
or less reddish white. I assume that the original specimens of ab. alba Dziurz. and ab. confluens Dziurz. 
(p. 22, line 15 from top), which aberrations Staudinger had mentioned in his description of separata, without 
giving denominations, were also captured in the Alexander mountains. Dziurzynski does not seem certain 
himself, whence the types originate, he illustrated as ab. alba a specimen that shows a combination of ab. 
alba and ab. confluens. In ab. alba the yellowish whitp circumscription of the spots of forewing are expanded 
to such an extent that it forms the predominant colour; in fact the entire inner surface is white and in same 
are situate the red spots, whilst the black ground colour is so suppressed that it is only visible at margin
