more robust, saccus deeper and broader. Ukraine: Bakhmut. May to early June, common; typical series in 
the Joicey collection. The Lithostege which Obraztsov records as common on the steppes about the Vess- 
jolaja Bokovenjka Park. 18 June— 11 July, will probably be found to agree with it.

but on the whole whiter (a trifle less bluish or greyish), the hindwing rather purer white, the forewing beneath

has in addition 5 from Almatinka. Valley Malaya River (East Turkestan), 16--21 June 1927 (B. Vorobiev)

L. ancyrana sp. n. (6i). At present I have access to regrettably few specimens of this species, but ancyrana. 
cannot pass it unnoticed in this revision; probably more material will be detected in our European collections. 
Prof. Seitz kindly sent me his Ankara (Angora) Lithostege for examination, but they included nothing nearer 
than griseata obscurata. It cannot be a form of farinata. as the J valve lacks the costal process of that species 
and narynensis; nor of palaestinensis , for the "costal arm” is more slender and less sinuous, the “clasper” of 
Amsel differently formed, set almost vertically, the juxta decidedly narrower, the “saccus" deeper. A rather 
small species, the length of a forewing averaging 15 mm. its breadth perhaps a trifle less in proportion than in 
farinata; coloration above and beneath about as in farinata , but the cell-mark is not discoverable in either 
example. Angora (Sureya Bey), 1929 and 1930, type and a paratype A in the British Museum, 2 furthered' 
in the Vienna Museum, one kindly lent by Dr. H. Zerny for corroboration of the genitalia. 
L. palaestinensis Amsel (8 f), as tested by the genitalia, has a considerably wider range than was given palaestinen- 
on p. 84; it has been traced, without any structural modification, to Arabia southward, the Taurus northward 
(and I see that Amsel mentions Konia, = Konieh) and even to Greece westward, as the British Museum has 
a well authenticated A from Delphi. 18 Ajiril 1911 (P. A. Buxton) ; my only Persian J (Kazeroun-Buchir. 
F. H. Brandt) also agrees essentially, though the slightly more slender juxta and a very slight modification 
in the shape of the valve may point to a separate race. It should be added that the Iraq specimens have a 
greyer tone, particularly on the hindwing, and may represent yet another race, as Wiltshire (who has good 
material) firmly believes. The Algerian and South European representatives have diverged further and I 
regard-them-as separate species. 
L. duponcheli sp. n. (18k. <$. U.). Amsel. in erecting his palaestinensis. expressed grave doubts whether duponcheli. 
farinata, really occurred in the Mediterranean countries at all. but did not indicate that he had examined any 
S. European. His suspicion, however, has been amply justified and the so-called farinata ; of the Bouches-du- 
Rhone, Digne, Sicily, etc. demonstrated by the genitalia, as well as by the coloration, to be a representative 
of palaestinensis. Generally rather large, the forewing beneath, even in the with very sharply de¬ 
fined dark proximal area, leaving free a white border of about 5 mm width anteriorly, which narrows to about 
half that width at midtermen and to about 1 mm at tornus. The valve differs in shape from that of palaestin¬ 
ensis; its dorsal margin is straight for more than half its length, its hindmargin markedly oblique; the costal 
arm is strikingly bent about the middle instead of regularly curved; the “clasper" is liable to asymmetry, that 
of the left valve, in the observed cases, developing an additional hook; labides larger and more hairy than 
in the allies. Duponchel recorded and figured this species from Sicily as farinata, long before Kruger redis¬ 
covered it there in 1905; probably Duponchel knew also southern French specimens. As type I have chosen 
a in the Tring Museum form Nicolosi, Sicily (coll. Ragusa). It occurs there in March and early April, in 
the Monte Gargano district and S. France in May. 
L. cinerata Trti. (= cyrenaica Amsel. err. transcr.) (8f). If this is the species which was formerly cinerata. 
circulated under the trade name of “ farinata var. algirica" (B.-Haas) it has evidently a very wide range in 
N. Africa, where it apparently replaces palaestinensis and duponcheli ; should the very material differences in 
the genitalia be considered subspecific only, cinerata would be the oldest name for the collective species. Most 
of the specimens known to me come from Tunis or eastern Algeria (especially the Biskra-El Kantara district),
