SPINIPALPA; XESTIA. By Dr. Corti and Dr. M. Draudt.

Subgenus: Aniphitrota Warr. 
Filip jev lias studied the question of the justification of this recently created Genus and has ascer¬ 
tained (Ann. Mus. Zook Ac. Sci. URSS. 1927, p. 234) that at best it may claim the rights of a subgenus, in 
which ravida Schiff. (compare p. 70 of this Supplementary Volume) should be included, owing to the similarity 
in the genitalia. Corti was inclined to think that stabulorum Bien. and glis Chr. should also be included. On 
account of superficial similarity we have classified them with the squalida group which is certainly 
closely related. 
Rh.unicolor Wkr. (Vol. 3, p. 57) is a purely american species! The alleged specimen from Kamschatka has unicolor. 
proved itself to be a nigricans L. and a second specimen, that had been bred at Sidemi, belongs to suecica. 
Rh. suecica Auriv. (Vol. 3,p. 57, pi. 15 k) appears to be widely distributed over Asia and Europe. Mean- suecica. 
while specimens have been captured at Moscow and Leningrad, as well as at Sutshan. Probably the species 
is often mistaken for others. Fillpjev designates same as an inhabitant of the forests of european Siberia. 
Rh. karafutoois Mats, is somewhat like squalida and is a large species with narrow wings. Forewings karajutoni 
dark grey with delicate black markings, transverse lines double, the posterior line boldly undulate and dentate. 
The large orbicular and reniform stigmata are elliptical; the large claviform stigma conical; veins slightly 
dusted with black in outer area, the subterminal line paler grey. Hindwings paler than forewings, darker at 
margin and with white fringes. Wing expanse: 47—49 mm. S. Saghalin in August. 
Rh. isshikii Mats, is closely related to the preceding species, but much smaller. Forewings dark grey isshikii. 
with reddish hue. At base a short black basal streak. Anterior transverse line double, the posterior one single 
with paler outer edge. Orbicular stigma oval, incomplete above and below, reniform stigma only indicated by 
a black dash, claviform stigma indistinct, beyond same a faint central line. Fringes paler than ground with dark 
basal line. Hindwings pale grey with whitish fringes. Wing expanse: 35—40mm. Saghalin. This and the 
preceding species are being placed here provisionally, possibly they woidd be better classified in the squalida 
group.

S. maculata Alph. (Vol. 3, p. 58). Compare also Vol. 11. p. 62. 
28. Genus: Xestia Hbn. 
X. antiqua Stgr. (Vol. 3, p. 58, pi. 15 k). 
X. koeppeni Alph. (Vol. 3. p. 58, pi. 15 k). 
X. ochreago Hbn. (Vol. 3. p. 58, pi. 13 i). This species, which has meanwhile also been discovered in ochreago. 
S. Bavaria (especially around Oberstdorf) varies in colouration from buff to fuscous and rufous. — pallida 'pallida. 
Schaw. has very pale yellow-brown, faintly marked forewings and straw coloured hindwings. The larva is pale 
green with indistinct pale lateral stripe and feeds on Verbascum and Tussilago, probably also on other low 
plants; it hibernates in the open, but can apparently be forced. Recently it has also been found in Albania. 
X. habichi Rbl. is almost exactly like ochreago, but differs in the antennae. In the without pectin- habichi. 
ations, serrate on inner side with two rows of fascicles of cilia, the length of which exceeds that of the width 
of the shaft. In the $ the cilia are longer and bolder than in ochreago. Length of forewings: 16 —17 mm. 
From the Schneeberg near Vienna in July. 
X. apfelbecki Rbl. <$ with ciliate bipectinated antennae. Forewings short and wide, pale ochreous yellow apfelbecki. 
with two delicate brownish transverse lines that are not dentated and with wide central shade. The stigmata 
are quite absent. Subterminal line extinct, inwards of same a faint brownish edge. Hindwings whitish, 
yellowish towards costa with delicate discal spot. Described from 1 $ from Bosnia. 
X. miniago Frr . (Vol. 3, p. 58, pi. 13 i). — antennalis Strd. is a form with pale brown antennae, those of antennalis 
the type form being white. Forewings with completely transverse diffuse central shade. From Asia Minor. 
X. xestiodes Hmps. (Vol. 3, p. 58, pi. 13 i). 
X. fuscisignata Hmps. (Vol. 3, p. 58, pi. 13 i). 
X. effundens Corti (12 f') should possibly be classified in a new Genus. Head and thorax are grey- effundens. 
brown like the abdomen. Forewings uniformly grey-brown. Of the transverse lines only the heavily dentate 
subterminal line is visible. Basally there is a very long, deep velvety brown basal streak. Orbicular stigma
