1. Family: Zygaenidae, Burnets. 
With the very extensive more recent literature, especially as appertaining to the Genus Zygaeiia, it 
was impossible in 1930 to make a complete survey embracing also the older literature. In the meanwhile a 
great deal of work has been done and especially the asiatic Zygaenidae have been subjected to a thorough 
revision. Besides a number of fresh descriptions and denominations have been established. 
2. Genus: Hieida Strd. 
p. 2, line 23 from below. — According to Daniel, Munich, persa Strd. may be held to be identical with 
Stygia ledereri Stgr. At the best persa Strd. may be retained as denoting a race of ledereri St.gr. Compare also 
what was said on p. 244.

p. 7, line 27 from top. Z. erythrus Hbn. The ab. hirpina Zickert (not irpina as stated in Vol. 2, p. IS) 
does not originate from the Riviera, but from Paternopoli (Avellino) Campagna. It flies mid July. The 3 longi¬ 
tudinal streaks of forewing form a solid red area, having suppressed all but vestiges of the dark ground colour 
on costal, inner and outer margins. 
p. 7, line 13 from below. Z. purpuralis Brunnich. The type race was described from Denmark (Isle 
of Seeland), around Copenhagen. I have received from the Zoological Museum of the University of Copen¬ 
hagen a series of freshly captured danish purpuralis from Adserho and Tisvilde in the north of the Isle of See¬ 
land and captured in July. In general these correspond to the original illustration of Brunnich of his pur¬ 
puralis in regard to size, wing contour and formation of spots. It would appear that purpuralis does not — or 
no longer does — occur in the immediate surroundings of Copenhagen. I therefore take the specimens of 
those populations from around Adserbo and Tisvilde as typical of purpuralis. They are relatively small speci¬ 
mens with short rather rounded off forewings and fairly deep blue-black bodies in greenish black in $ and 
especially the d has densely haired body. Ground colour in d is generally bluish black and glossy, in the $ 
it is more inclined to be greenish black. The red of the spots of forewings and the hindwings is a rather dull 
dark carmine. The scales are not less dense, in fact in some dd they appear to be denser than for instance 
those of the populations from around Berlin. The size of the spots on forewings adapts itself to the size of 
the specimen, sometimes the streaks are separated, sometimes they merge, but in no specimen are they inter¬ 
rupted. The wedge-shaped spot is generally small, not expanding towards apex, occasionally it approaches 
fairly close to margin, in others spot 6 is only faintly indicated. The margins of hindwings in the dd are only 
visible at apices and they are lighter than the dark fringes. The have no margin to hindwings and some¬ 
what paler fringes. One d has fairly wide, almost uniformly wide margin to hindwings right to the inner 
margin: ab. latemarginata ab. nov. The few specimens before me from Rorwig, Hornbaek and also from Faxe latemargi- 
on Seeland, similarly those from the Isle of Moen scarcely vary at all from the type population, purpuralis 
is said to also occur on the Isle of Fiinen near Faaborg. 
The var. caledonensis Reiss from around Oban (Argyle), W. Scotland, is much more thinly scaled caledonen- 
than typical purpuralis, but is just as densely haired as same. In regard to the sparse scaling, it approaches 
the var. nubigena Led. from the High Alps, but on an average it is larger and has rather bolder clubs to an¬ 
tennae. The central of the red streaks is abbreviated and only diffuses slightly at its extremity, the streaks 
are merely separated by the blackish veins. The blackish margin at apex of hindwings of d is as in typical 
purpuralis. 
Irish specimens in my collection, labelled Clare coast and Ardrahan, Galway, ex coll. Tutt, captured 
end of June, show a red colour that appears more or less admixed with yellow and differing from all danish, 
Scottish or german populations known to me. Those from the first-named locality are smaller than purpuralis, 
whilst those from the latter are almost as large as german specimens. In other respects and in the formation 
of the spots they are very similar. The hairs of the body in the dd are not more dense, the scaling is par¬ 
tially somewhat weaker than in german specimens. I denominate the race: hibernica var. nov. (= nubigena Mbemica.
