Addenda: ZYGAENA. By H. Reiss. 2o9 
The original types of subsp. rosacea Bomff. originate from Istissou, west of Erivan in Armenia. It 
is very distinctly distinguishable from cambysea by the more brilliant, purer rose-red and the inclination in 
nearly all specimens of spots 1, 2, 3 and 4 of the spot area to become confluent with the apical spot (5 and 
6). Generally also rosacea is larger and more robust than cambysea. The confluence of the spots of forewmgs 
is in some specimens so great that the spot area of the wings is completely rose-red. Specimens with a 
similar arrangement of spots to those of cambysea are denominated pseudocambysea Reiss. In the $ the differ- P °* udoeam - 
ences, as compared with the already mentioned under cambysea occur in a still more marked degree. 
p. 19, line 24 from top. Z. armena Eversm. (= kadenii Led.) is described from the South of the Cau¬ 
casus and recognisably illustrated on pi. 7 c in Vol. 2. It always has a complete brilliant red abdominal belt 
and can be recognised thereby. Romanoff says it is very frequent in June and July at Borjom, Achalzich 
and Abbas-Tuman. I select the population at Abbas-Tuman as type race. In regions at high altitudes m 
these territories it seems to form alpine populations of var. caucasica Rbl. ( Stgr. i. 1. p. 19).

of Barege in the Pyrenees. The first indication of Boisduval as “S. Spain" is not confirmed. 
p. 20, line 20 from below. Z. graslini Led. This Zygaena, that is probably closely related to the ihada- 
manthus-oxytropis group, was first discovered (flying in April) by Franz Zach near Beirut in Syria. Wing 
contour similar to that of rhadamanthus or oxytropis. The hairs of the body, especially in the are dense, 
bristly and black. Legs and antennae similarly coloured. The latter especially in the $ are very heavy and 
terminate as in rhadamanthus in a heavy blunt club. Forewings are dull steely blue or greenish black. The 
usual markings consist of 3 pairs of brilliant vermilion spots, one over another and sharply outlined. r Ihe 
inner 2 pairs (1, 2 and 3, 4) narrowly divided by the inner marginal nervure of discal cell, the outer pair 
(5, 6) however always attached. Spots 1 and 2 are the longest, both equally long and each double as long 
as wide, spot 1 almost touches the costa. Of the central pair (3 and 4) spot 4 is larger than spot 3, it is 
irregularly formed and situate obliquely outwardly. Of the outer pair (5 and 6) spot 5 is about the same shape 
as 3 and 4, in size however it is about midway between them. Attached to same on the marginal side is 
spot 6. Hindwings are cinnabar red with narrow black margin. On underside forewings are thinly scaled and 
the red markings are nebulous and confluent. Hindwings have underside like upperside. Frequently spots 
1 and 3 or the central pair become confluent, rarely however all spots are conjoined. In ab. confluens Dziurz. 
spots 1 and 3, as well as 2 and 4 become confluent forming longitudinal streaks, occasionally also spot 5, 6 
is conjoined with spots 3 and 4. This covers the original ab. confluens Dziuiz. from Beirut. In older to 
avoid unnecessary denominations I include all possible forms of confluence under the designation ab. confluens. 
As Lederer in his original description of the type race mentions that forms of confluence are not rare, 
there is no justification to denominate any of the transition forms of ab. confluens Dziuiz. 
In the 2nd half of June an easily distinguishable and uniform race occurs at Bjarre in the Lebanon: 
var. pfeifferi Reiss (16 i). It is constantly smaller than the type race from Beirut. Forewings show nearly pfeifferi. 
the same degree of heavy blue or green metallic gloss as for instance oxytropis from Genoa. Spots of forewings 
and hindwings are never vermilion but always more of a pale carmine red. Antennae are approximately as 
in the small oxytropis var. laterubra from Mt. Sirente in the Abruzzi. Those of $ with rather heavier clubs 
than those of $. pfeifferi approaches laterubra in general appearance owing to the extensive reduction of the 
spot markings. A faint confluence on the vein between spots 1 and 3 is of rare occurrence. Spots 3 and 
4 are completely separated by the ground colour in abt. one quarter of the specimens before me. The 
nebulous red between the paler spots on underside of forewings is generally reduced and the area between 
spots 3 and 5 usually consists of a more or less distinct blue-black patch entirely devoid of red scales. A 
cotype ex my collection is illustrated. 
The var. kulzeri Reiss from Zebdani in the Antelebanon occurring in the 1st half of May at an alti- kulzeri. 
tude of 1100 m has a charateristically short and wide wing contour, whilst the clavate antennae are heavy 
and decidedly long. The scaling is not uniformly dense in all specimens, especially the $$ are often less 
densely scaled than the type race of graslini. Such specimens that are more heavily scaled resemble in co¬ 
louration and formation of spots normal specimens of the type race of graslini from Beirut, but the ed especi¬ 
ally of hindwings is occasionally somewhat admixed with pale carmine. Forewings show a very dull blue ox 
green gloss. The inclination of the spots of forewings towards confluence is decidedly less than is the case in 
graslini from Beirut. A specimen before me captured on 31st March near Damascus has a ceitain resem-
