EUPITHECIA. By L. B. Pbout. 
prouti. has been obtained in some numbers from Guelt-es-Stel, Central Algeria. — prouti Zerny , erected as a sub¬ 
species of deverrata, was discovered in June in the Northern Lebanon and must have a different life-history, 
as Pityranthus is there wanting. On an average larger than the type (length of a forewing 9—1114 mm), lighter 
clay-colour, forewing with the cell-mark less characteristic, though thicker, costal marks darker, postmedian 
more distally placed. Similar but rather sharply marked specimens from the Taurus Mountains, formerly de¬ 
termined as albidulata form, probably belong here, though Zerny calls typical prouti “much more unicolorous 
and much less sharply marked" than lecerji. 
brunneata. E. brunneata Stgr. (14 f) is another species which in 1913 was comprehensively (but inexactly) quoted 
by Dietze under pantellata. Besides Mesopotamia, it occurs in desert localities in Palestine. We figure a $ 
from Ghor el Safieh, S. of the Dead Sea, where it was collected in March. 
circumdata. E. albidulata Stgr. ab. circumdata Dietze. Clear white with pure black markings, without any trace of 
Umbofascia- brown. Both sexes from Gudaur, N. E. Caucasus. — ab. limbofasciata Dietze. Borders almost uniformly black, 
ta ' the white subterminal line and its white central spot almost entirely suppressed. 2 collected with ab. 
circumdata. 
schwingen- E. schwingenschussi Zerny (14f) was described as related to liguriata. Antenna of the very shortly 
scliussi. c pi a ted; palpus as short as in liguriata; ventral plate totally different from Petersen's figure for liguriata, 
distally with a circular excision, the lateral parts rounded, convergent; “vesica” with 2 thick, elongate chitin- 
ous formations, placed side by side. Wings white-grey with a slightly yellowish tone, which in the distal area 
and on the fore wing also at the inner marginal area is overlaid with light leather-brown; forewing wit h large 
cell-spot and with the lines arising from deep-black costal spots, terminal line sharp, black, narrowly inter¬ 
rupted at the veins; hindwing, except the marginal band, sprinkled with coarse dark scales, with 4 wavy 
blackish lines and a narrow pale subterminal band. Tachdirt, Morocco, 2300—2700 m, June and July. It looks 
to me much closer to irritaria, the face somewhat less prominent, the wings perhaps a trifle broader, the 
forewing with a cleaner white band outside the postmedian; the hindwing beneath with better developed 
cell-dot. For examples of this and many other rare species I am indebted to the generosity of my friend Mr. 
Leo Schwingenschuss. 
irritaria. E. irritaria Stgr. (14 f). We figure a specimen from the Wehrli collection. The range extends to De¬ 
mavend. 
E. marasa Wehrli (14 f). Similar to irritaria Stgr. and irriguata Hbn. (Vol. 4, pi. 13 e) but larger. The 
palpus extends beyond the frons by about % the diameter of the eye; the frons has a strong, bluntly coni¬ 
cal protuberance, about double that of irriguata ; both it and the palpus are darker. Antennal ciliation shorter. 
Forewing with apex more acute; ground-colour less white; markings similar, but the subbasa-l line looks 
different, more incurved in the middle etc.; cell-dot moderate, deep-black, smaller than in irritaria and 
not Avlnte pupilled, present beneath (in irritaria wanting beneath). Marasch, Syrian Taurus, 3 <3$ and 1 $, 
collected in March, whereas irritaria flies in July. 
E. irriguata Hbn. (Vol. 4, pi. 13 e). The protuberant frons in this species and insigniata , commented 
upon by Wehrli in erecting marasa, would remove these three and a few others (compare tenellata, Vol. 4, 
p. 295) to a separate genus ( Nasusina Pearsall — Prorella Barnes db Me. D.), according to the classification 
of the American systematists. This change may ultimately have to be adopted, but its taxonomic implica- 
eriguata. tions have not yet been explored in relation to the Old-World faunae. — eriguata Rmb. (18d) (not erriguata 
as in the German edition of Vol. 4 and the index). Perhaps this name should be applied comprehensively 
to the Mediterranean forms, which are very distinct from the whiter name-type. Like some other southern 
jranconica. forms, they prevail also in the Middle Rhine. — ab. franconica Dietze. Still more poorly marked, the black 
markings, especially in the §, dissipated into a regular grey irroration. Middle Rhine district, not rare among 
mauretanica. eriguata. — mauretanica Dietze (Vol. 4. p. 287) is variable and I am not sure whether it can always be sepa¬ 
rated from eriguata; typically it has the median area darkened, the white stripe outside it well developed. 
kurdica. Morocco is to be added to its range. — kurdica subsp. nov. (14 f) is another strongly darkened form, variable, 
but decidedly less brown-tinged than the eriguata series (including even mauretanica), the median area scarcely 
ever band-like, the white stripe outside it not well defined. As it is slightly intermediate, in the pointed 
wings and strongly protuberant frons, towards marasa (which Wehrli is convinced is a species), it is possible 
that kurdica should also be given specific right. On the 2nd median, the 3 lines and the 2 subterminal shades 
are about equidistant, though the latter are broader and less defined; in most irriguata the space between 
the two groups is a little wider and the “lines” commonly broken or mere vein-dots or dashes. From the 
somewhat larger but likewise grey (or still greyer) marasa , this new form differs not only in the structural 
details mentioned above, but also in the less strongly darkened costal markings and perhaps the less bidentate 
median lines of the forewing posteriorly (the only marasa before me is here rubbed and has lost both anten- 
m am sa. 
irriguata.
