The species seems to be rare in collections. He adds that the particulars given by Corti (Ent. Mitt. 1927, 
XVI, p. 71) in regard to a subdivision of this group, into those with projection and those without projection 
at the lower edge of valve, are incorrect and not in accordance with actual facts. Boursin, who has examined 
the genitalia of all the species of this group, as far as were available, hopes to publish very shortly a recapitn 
lation dealing with the whole group. In this, the above species from the Taurus and Ak-Shehir, will be described. 
Meanwhile it may be remarked that — obumbrata Stcjr. (Vol. 3, p. 55) is a genuine species, that has no connection obumbrata. 
with sollers. — sollertina Cti. (Suppl. Vol. 3, p. 67, pi. 9 d). According to Boursin this is only a palerspecimen solbrtina. 
of obumbrata. 
Rh. obsoleta Cti. (Suppl. Vol. 3, p. 67, pi. 9 d) from the Lebanon, is according to information from obsolete. 
Boursin, certainly a genuine species, that has no connection whatever with Candida Stgr. (Vol. 3, p. 55, pi. 13 d; 
Suppl. Vol. 3, p. 67). It may possibly be related to socors Cti. (Suppl. Vol. 3, p. 68, pi. 9 e), which was described 
from the Alexander Mountains and Djarkent. 
Rh. paralia Cti. (Suppl. Vol. 3, p. 67, pi. 9 d). Boursin considers this identical with Candida. Stgr. par,ilia. 
Rh. dormitans Cti. (Suppl. Vol. 3, p. 67, pi. 9 c). According to Boursin this should certainly be classified dormitans. 
with laetifica. 
Rh. damnata sp. n. (pi. 26 b). According to the opinion of Mr. Boursin this is a new species in this damnata. 
extremely difficult group of forms around sollers and closely resembles the anatolian pseudo sollers that has 
not yet been described . Wing contour is elongate and narrow as in related species. Head and thorax glossy 
vellow-grey, sprinkled with brownish, base of palpi and edges of eyes inclined to ochreous. Forewings have 
pale ochreous grey ground densely speckled with slate-grey, most densely in marginal area. Subbasal and 
anterior transverse lines double, slate-grev, interfilled with pale ochreous yellowish. The posterior transverse 
line is single, rarely double, boldly crenulate with pale outer edge. The orbicular stigma is yellowish, a supine 
very small narrow oval. Reniform stigma is completely obliterated by the dark central shade, or is only faintly 
indicated in paler outline. There is practically no trace of a subterminal line or on its inner side there are some¬ 
what darker grey sagittate streaks that more or less merge with one another. Marginal line bright ochreous, 
fringes darker grey in basal half, paler at extremities. Hindwings fairly dark grey-brownish with darker veins 
and discal lunule and almost white fringes that are somewhat yellowish at base. On underside the hindwing- 
have a wide dark marginal band, that is fairly definitely outlined by the postmedian. Very variable in the 
paler or darker ground colour and the distinctness of the transverse lines. The genitalia are said to differ from 
sollers by the more heavily chitinised penis, increasedly elongate valves and longer and narrower claspers, also 
the dentate projection at lower edge of valve is longer (Boursin). A large number of these have been received 
from the Elburz mountains (Tacht i Suleiman) from Pfeiffer; July 1936. Types in the collection of Draudt, 
cotypes in the collection of Pfeiffer. 
Rh. figulina Drt. (pi. 25 c) belongs to the same group of forms as the preceding species. It. has long narrow figulina. 
forewings of reddish clay ground colour, suffused with grey-white at costa and inner margin. Markings leaden 
grey, in similar arrangement to the preceding species. Transverse lines single, crenulate. Orbicular stigma is 
a grey dot, reniform stigma a faint grey crescentiform streak. Subterminal is absent; there are small black 
triangular dots anterior to a reddish yellow fringe base line. The fringes themselves are pale grey, with paler 
division. Hindwings brownish white with brown veins and discal lunule and white fringes. There is a marginal 
line expanding between the veins. Described from 1 $ captured in July at Ak-Shehir. 
Rh. helvetina Bsdv. (Vol. 3, p. 51, pi. lie; Suppl. Vol. 3, p. 68) — lhassen Le Cerf denotes an ochreous lhassen. 
grey race, in which the pale ochreous stigmata and transverse lines are more prominent and brighter. Wing 
expanse: 41—45 mm. Central Atlas, Morocco in August. Obviously very close to gilva B.-H. 
Rh. gilva A. B.-H. (Suppl. Vol. 3, p. 68). We are now able to give an illustration (pi. 24 i) of a specimen gilva. 
from Ak-Shehir, where the species is now also found in the Sultan Dagh at an altitude of 2000 m. It seems 
however to be certainly only a form of helvetina . 
Rh. dyris Zerny (24 i) very closely resembles darker gilva specimens, but is a genuine species, which dyris. 
differs from helvetina by the different build of the antennae and genitalia. Ground colour is inclined to be a 
pale brownish red, frequently with roseate hue, the markings are otherwise almost identical; central and sub¬ 
terminal areas are faintly darker, in the former the stigmata, which are without darker surrounds, seem to 
stand out more palely. From the High Atlas (Tachdirt) Morocco at an altitude of 2700 m. A very pale red 
specimen has been named — ab. rosea Schwing. ~ rosea. 
Rh. flavida Cti. (Suppl. Vol. 3, p. 71). As stated under E. amoena (p. 242) this is synonymous with 
the latter. 
Rh. roseoflava Cti. has been temporarily classified with similis Stgr. (Vol. 3, p. 40; Suppl. Vol. 3. p. 70) roseoflava. 
of which it was held to be a form. According to Boursin it is a genuine species that lias no relationship with
