area of 1—2 mm width. On underside of fore wings there is a dark patch from the outer line towards the base 
and especially above the inner margin. Hindwings are almost as dark on underside as on upperside. According 
to Rothschild bomilcar = serrula-undulata Stgr. which was not illustrated in Vol. 2. Lambese. In regard to 
bomilcar $ and hamilcar see remarks under davidis. 
aucta. L. eversmanni Eversm. (Vol. 2, p. 159, pi. 25 f.). —- The form aucta Krul. (9 f) is newly described. It 
was illustrated long ago in a butterfly book of Hoffmann *). Whilst bomilcar only differs very slightly from 
serrula and is separated as a species, aucta varies to such an extent that it might even be taken as a form of 
trifolii. The B is pale reddish brown on forewings tc the outer line, yellow brown on inner margin and in marginal 
area. Hindwings somewhat paler than forewings. The $ is paler on forewings with diffuse dark outer line. Hind- 
wings are almost darker than forewings. Sarejita. — The typical form also occurs in Sarepta. Generally the 
specimens in the hindwing resemble the illustration in Vol. 2, pi. 25 f, except for the dark band which is normally 
absent. The species is distributed as far as Corea. The only good specimen from there before me has a dark 
band at base of forewings similar to southern trifolii forms, for instance ratamae H.-Schaff., and the hindwing 
is somewhat darker reddish brown than is illustrated on pi. 25 f. and without a band. The other specimen I have 
is too worn and rubbed. 
hamilcar. L. davidis Stgr. (Vol. 2, p. 160, pi. 26 a as palaestinensis). — hamilcar Oberth. B from Lambese so 
closely resembles davidis that we are dealing with same here. The B differs from davidis B on forewings by a 
somewhat more yellow tone of the ground colour. In the illustration (Vol. 2, pi. 26 a) of davidis the middle 
band of hindwings is shown as being too wide and short and the margin too widely dark in comparison to the 
single specimen at my disposal. In hamilcar (10 d) the band of hindwings is as narrow as that on the forewings 
and there are only small dark spots at the margin. The band of both wings on underside of hamilcar is some¬ 
what diffuse inwardly. The $ which is designated as bomilcar $ by Oberthur appears to me more probably 
to belong to hamilcar. In ground colour it corresponds almost to the davidis $, Vol. 2, pi. 26 a, but the darker 
outer line is more distinct on both wings, beyond same there is a space of 2—3 mm which is widely pale 
schulzi. and the space towards the base is faintly darkened. — schulzi 2 Stertz (9 g) is a somewhat more yellowish form 
of davidis $. Except for this yellowish tone the illustration of davidis $ pi. 26 a (3rd fig.) would agree with 
same, but the line of forewings is slightly fainter, whilst typical davidis have still a less faint band, same as 
is illustrated in eversmanni B, on pi. 25 f. We are now illustrating this form mentioned in Vol. 2, p. 447. -—- 
According to Rothschild davidis is the extreme pale form of serrula-palaestinensis and hamilcar the pale form 
akbesiana. of serrula-undulata (= bomilcar Oberth.). —- akbesiana Oberth. from Akbes has a very glossy ivory white ground 
colour and a sharply prominent white discal spot on forewings. There are no other differences as compared 
to davidis. 
L. josua Stgr. (Vol. 2, p. 160). As in Vol. 2, pi. 26 a another species w r as illustrated under this name, 
we are giving a correct illustration here (9 f ). — Oberthur did not appear to be quite clear about vaucheri Blach., 
which was already dealt with in Vol. 2, because he later on deemed the specimens illustrated in Lep. Comp. 11, 
Fig. 4721 and 4722 to be a trifolii form. It is true that vaucheri B Oberth. shows a less sharp pale band on both 
wings than the illustration of vaucheri Blach. and in vaucheri Oberth. In ^ the pale band on hindwings is absent. 
However in the collection of Pungeler there are 2 vaucheri $$, clearly from the same brood, of which the one 
has a pale band on dark ground on forewings whilst in the other the relationship is reversed viz: the band is 
the darker. —- deleta Bothsch. is the same as trifolii-mauretanica Stgr. — Probably it will be ascertained later 
that serrula to josua are all only trifolii forms. The small differences in the larvae prove nothing. In Somabrachys 
formerly there were an innumerable number of species described with slightly different larvae and then one 
day they were all confined to 3 species. 
The species of the following groups differ from those of the former ones by the absence of the discal spot 
on fore wings and the outer line on both wings. (Subgenus Lambessa Stgr.) 
decolorata. L. decolorata King (9 g). According to Rothschild datini Mab. which was dealt with in Vol. 2, p. 160 
as a separate species, belongs here. — For the description of decolorata I formerly only had the $ before me. 
Stertz describes the B : ground colour of both wings monotonous buff-grey, somewhat olive-grey, slightly 
virago, pa Lei' at base. It agrees completely in the colour with the illustration of staudingeri in Vol. 2, pi. 26 b. — - virago 
Bothsch. (9 g). The B is grey on both wings, paler than decolorata. The $ has somewhat darker brownish fore- 
sordidior. wings than hindwings. Biskra. — sordidior Bothsch. (9 h) from the high plateau in Central Algeria is brownish 
grey. Body and inner margin of hindwings ochreous. The $ is cinnamon-brown. Such colour variations are 
of little value as everyone sees or describes the colour slightly differently. For instance the B which is sent to 
me as sordidior from the Tring Museum is much paler than the specimen winch Stertz has designated decolo¬ 
rata B, whilst various sordidior in the Pungeler collection are scarcely paler in comparison. We are illustrating 
a specimen of these under the name decolorata (9 g). Rothschild does not give a description of the colour of 
typical decolorata. 
pungeleri. L. piingeleri Stertz (= albescens Bothsch.) (9 f, g) is certainly a different species from decolorata as the 
antennae of the B are shorter and the abdomen of the $ longer. Besides this the species is so variable in
