dark specimens from Amrum, a superficial similarity to dissimilis is created by the deep grey-brown forewings 
and the sharply contrasting yellow-white subterminal line; the marginal area anterior to subterminal line is 
purer brown, beyond same to margin very dark slate-grey, like the lower half of the reniform stigma. Identical 
specimens, that therefore represent this same form, are also before me from Bulgaria, only the patch anterior 
to subterminal line is a more pronounced rusty brown in comparison to the slate-grey marginal area. — subsp. 
cinnamomina Rothsch. (14 b). All specimens from Algeria incline to cinnamon rose and are less grey than euro- dnnamom'i- 
pean specimens. Generally however, they are also very variable in size as well as in the distinctness of the 
markings. The larvae feed on Peganum harmala, burying themselves deeply in the sand by day; the lateral 
band is rose, edged on both sides by white and narrower than in trifolii. It is fullfed in January and the ima¬ 
gines emerge in March. It has also been found in Cyrenaica and on Sardinia (Aritzo). — fruticosae Dumont, fruticosar. 
It has yet to be ascertained whether this is the same species. The projecting process on frons is less pronounced, 
besides it is smaller and colouration is more inclined to ochreous rose. The lines are more delicate and a purer 
brown-black, hindwings with wide brown marginal band. The larvae feed exclusively on Salsola fruticosa. 
Tunisia (Tozeur). 
S. chimaera Rothsch. differs from the similar cinnamomina by its larger size and narrower wing contour. cMvuiera. 
It is a bright pale brownish grey with very large round reniform stigma and a blackish submarginal band on 
forewings. Veins of hindwings are sharply outlined grey-black. Wing expanse: 43 mm. From one from Ain 
Sefra (Algeria), captured in March. 
S. ghigii Trti. From the description this species comes between sodae and stigmosa. It is somewhat paler ghigii. 
than the former, but a deeper grey than stigmosa. Markings are very similar but the orbicular stigma is a 
large round white spot and the reniform stigma, which otherwise is not clearly marked, has a distinctly sharp 
white inner edge. Marginal area is scarcely darker than ground colour, with indistinct subterminal line. The 
small dark preapical spot, which the two above named species possess, is absent here and the two transverse 
lines are scarcely visible. Claviform stigma small and short. Hindwings white as in stigmosa with wide dark 
marginal band and a central line indicated. Collar without black line. Wing expanse: 30 mm. Derna (Cyrenaica). 
S. marmorosa Bkh. (Vol. 3, p. 68, pi. 15 h). — obscura Hoffm. are dusky specimens from Styria, which obscura. 
closely resemble microdon. — dalmatina Schwing. is also close to microclon , but smaller, more monotonous in dalmatina. 
colouration, especially the “W” mark of the subterminal line and the sagittate marks are much less distinct. 
Hindwings darker only in the outer third. Dalmatia. 
S. implexa Hbn. (Vol. 3, p. 68, pi. 15 k). The illustration is cpiite unrecognisable. It was the copy of implexa. 
a copy. We are giving (14 b) a good illustration of a specimen from Aflou from the collection of Pungeler. 
The species is widely distributed over Algeria. At Lambessa for instance it is common from April to June. 
Fritz Wagner has also discovered it in Anatolia. 
S. schawyra O.B.-H. (14 b) should be classified after dianthi (Vol. 3, p. 68, pi. 15 h). It is smaller schawyra. 
than the latter; ground colour of forewings grey-brown, the brown claviform stigma contrasting distinctly; 
orbicular stigma white, reniform stigma brownish with irregular circumscriptions, the two transverse stripes 
are double; fringes with brown checks. Hindwings impure grey with dark outer margin. Wing expanse: 30 mm. 
Tannuola mountains: Sliawyr, at an altitude of 2500 m, in June. 
S. pugnax Hbn. is the valid name and replaces treitschkei Bsd. (Vol. 3, p. 68, pi. 18 a). As the illus- pugnax. 
tration in Main Volume does not truly represent this species, that is like trifolii and marmorosa, we are giving 
a better illustration here (14 b). Colouration is more monotonous than marmorosa , fringes of hindwings always 
a brownish hue, whilst in marmorosa they are yellowish white. Genitalia differ considerably from trifolii. A 
very widely distributed species; besides occurring in S. France, it is frequently found in Morocco to Algeria 
and Tunis, where it is found only from September to November; in Algeria it seems to occur almost 
throughout the year. According to Vorbrodt it also occurs in Switzerland; in the Pungeler collection there 
are specimens from Spain — among them an aberrative, darker blackish form —, Portugal, Sarafshan and 
Issyk-Kul! — petricolor Trti. is described as a local race. It has a purer ashy grey ground colour without pelricolor. 
the brownish tone of the type form. From the Apennines of Modena in July. 
S. sodae Rmbr. (Vol. 3, p. 68, pi. 15 h). We are giving a better illustration here (14 b). — subsp. rosacea rosacea. 
Rothsch. (14 b) denotes the generally smaller specimens from Algeria and Tunis that have a more rosy hue. 
It occurs from March to June. 
S. salicorniae Dumont is as large as sodae and similarly marked, but the forewings are white with salicomiae. 
sharper and more distinct markings, reniform stigma is wider and less long, grey-brown, paler whitish at top, 
darker posteriorly with black circumscription and elliptical at top; orbicular stigma of the same shade as ground 
with black circumscription, nearer to the reniform stigma than in sodae, the ground between same being pure 
white; claviform stigma is distincter and larger than sodae-, lines are faint, the posterior one being nearer to 
reniform stigma with rosy white outer edge. Subterminal line is bright brown with white outer edge. Be¬ 
tween veins 6—3 there are three brown sagittate marks. In front of the black-brown marginal line there is a 
white line, which at apex and anal angle expands to spots. Fringes have brown and white checks. Hindwings 
pure vhite with brownish speckles in marginal area and bright brown marginal line; fringes white or pale rose.
