PFEIFFERELLA; LEUCOCHLAENA. By Dr. M. Draudt. 
barthae. C. barthae Wgnr. is like platyptera and especially the subalbida form of same and hamifera, but it 
is more sleekly built and the dark shade at anal angle and along inner margin is completely absent. Forewings 
uniformly pale grey. In apical area below the point there are 2 short black longitudinal streaks and 2 longer 
ones below the centre with a similar basal streak. Only the orbicular and claviform stigmata are finely out¬ 
lined by black, reniform is absent. Fringes whitish with dark checks. Hindwings grey, darker at margin with 
faint central spot. The species is no doubt a transition to the following three species, which all closely resemble 
one another. Wing expanse (according to the illustration): 27 mm. Described from 2 specimens from Akshehir 
(Anatolia). 
stigmatica. C. stigmatica Bothsch. (— pintori Trti., volmeri M. Bering) (16 i). A smaller species related to the 
preceding. Body and forewings whitish blue-grey with 2 black basal streaks. Both transverse lines indistinctly 
double. The stigmata somewhat paler than the ground, especially the claviform stigma, with fine black sur¬ 
rounds. The orbicular stigma is elongated. In marginal area an oblique shadowy stripe at apex, below same 
above centre of margin, a second longer oblique shade, having a faint whitish outer edge, both these shades 
traversed by black longitudinal streaks. All marginal veins delicately black. Hindwings opalescent, grey- 
white with dark marginal band. Algeria and Tunisia, also occurring in Cyrenaica, but apparently rare every¬ 
where. 
danieli. C. danieli Le Cerf is very like stigmatica. Forewings ashy grey, paler at base and terminally; darker in 
centre. Anterior transverse line double, consisting of 3 irregular arcs, the posterior one angulated, indistinct bet¬ 
ween costa and vein 4 and only consisting of black streaks on veins; in lower half distinct and black, duplicated 
by a diffuse outer shade. There is a parallel central shade inwardly of same. Orbicular stigma small, longish. 
reniform stigma larger, outwardly concave, with brownish centre. All three stigmata with delicate black 
surrounds. Veins 1 to 4 are faintly blackened, between veins 6 and 7 a bolder sagittate streak. In the inter¬ 
stices there are delicate marginal sagittate marks and 2 oblique subterminal shades between 1 and 3. Hind¬ 
wings pale yellowish grey, darker at margin. Wing expanse: 26 mm. Marakash. 
liberal ii. C. liberatii Ttri. (16 i) belongs to the same group but is smaller. Forewings monotonous ashy grey, 
the black markings being less prominent and very delicate. Reniform stigma very small with pale centre and 
dark central dot. Orbicular stigma also small and claviform is somewhat paler grey with a thin black basal 
streak anteriorly. Below the apex is an oblique row of black intercostal sagittate marks, submarginally near 
anal angle there are further black sagittate streaks. Hindwings dark smoky grey, still darker in §, with whitish 
fringes. Wing expanse: 19—20 mm. Bengasi (Cyrenaica) in February. 
biroi. C. casta Bill. (Vol. 3, p. 117, pi. 29 c). In — ab. biroi Aigner basal area of forewings is whitish grey 
castior. and the central shade extends towards the apex. Hungary. - castior Stdr. has basal area of forewings white, 
but otherwise the white colouration is also extended and the brown is heavily interspersed with white. Mar¬ 
ginal band of hindwings is very narrow, especially in Spalato. 
16a. Genus: I*feiflferella Osth. 
This forms a transition to the subsequent Genera owing to the completely absent proboscis. Clypeus 
smooth; palpi very short, straight and porrect, with dense hairs on underside; <$ antennae very elongate, bi- 
pectinated from two-thirds length of costa to tip, in $ serrate ciliate. Thorax and body sleek with coarse hairs, 
in the A with bold anal tuft, in 9 with somewhat protruding ovipositor, the first abdominal segment with loose 
crest. Tibiae without spurs. The neuration does not vary from the usual arrangement, on hindwings veins 
6 and 7, frequently also 3 and 4 with short stalks. Apart from the absence of the proboscis, it does not vary 
from the Genus Bombycia and it is very similar to B. chretieni. Only 1 species: 
<jracilis . PC gracilis Osth. (16 i). Forewings whitish silvery grey, the costal area from base to apex, including 
the stigmata, rather darker grey. Transverse lines are absent or only very faintly indicated. The stigmata 
brownish white with delicate black surrounds, reniform stigma of rectangular shape. On costa there are a few 
blackish striations and between them small white costal dashes in the outer one-third. Veins in marginal area 
and marginal line delicately black. A somewhat oblique bold black streak above anal angle. Fringes whitish 
at base with dark grey tips, white at extremities of veins. Hindwings pure white in $ with fine black marginal 
line; grey in $, widely dusky at margin. The ^ has a somewhat reddish brown tinge on the rather darker 
wings, more especically between the stigmata. Described from Marash (Taurus), occurring in September 
and October. 
17. Genus: T^encoolilaeiia I-Imps. 
] ltir _ L. horhammeri Wgnr. most closely resembles fallax Stgr. (Vol. 3, p. 11S, pi. 2S D) but is immediately 
hammeri. distinguishable by the complete absence of the wide white subterminal line in marginal area of forewings. The 
other white markings merge in the blackish grey ground colour. Claviform stigma is rather darker than
