A. distigma Chret. is classified by its author next to atriluna, but according to Rothschild it would 
be better placed near to oberthuri. Forewings pale ochreous yellow', bestrewn with ochreous red and black 
scales, especially around the subterminal line. The transverse lines are very fine brown double lines, inter- 
filled with the ground colour and commencing at a costal mark. Subterminal line consists of spots. Both 
stigmata are distinctly prominent, black with rusty brown scales. Hindwings white, dusted with grey sub- 
apically. Head ochreous yellow. Wing expanse: 26—-27 mm. Algeria. 
A. melanurina Stgr. (Vol. 3, p. 214, pi. 45 g). The wing contour of the illustration was not satisfactory, 
but we are not giving a fresh reproduction. The pretty little species is very like Rhyacia melanura, for which 
it might be mistaken. However it can be immediately distinguished from same by the anatomical differences. 
Hindwings are sometimes completely suffused with grey. It is said to also occur in the Taurus (Marash). 
74. Genus: JPetilampa Auriv. 
P. arcuosa Haw. (Vol. 3, p. 215, pi. 45 h). The name ‘’'minima Haw.” is to be deleted here, as it refers 
to Miana captiuncula (vide what was said there). —- airae Frr. denotes a much more brightly and clearly marked 
reddish brown form and should therefore be removed from the synonyms. — ab. Iuciola Prohaslca has coppery 
brown fore wings with dark discal area. Described from Gratz. 
P. palustris Him. (Vol. 3, p. 215, pi. 45 h) — raebeli Dhl. is a form from Gleiwitz in Silesia, that is 
very dark, unicoloured grey to brown-black with scarcely any markings. The $ is completely black and very 
glossy. — obscura Hoffm. & Klos is a transition to same, similarly very dark, but not quite so black. Styria. 
— lutescens Farr, is paler, forewings ochreous yellowish grey. —- fusca Farr, has forewings duskily blackish 
to the posterior transverse line. — melanoehroa Stgr. It seems to me doubtful, whether this is a form of this 
species. It is certainly much darker and more clearly marked and we are illustrating a nice specimen (21 k). 
75. Genus: Dysmilicliia Speiser. 
D. gemella Leech (Vol. 3, p. 215, pi. 45 h) — sutchanica Filip], is distinctly larger than type, it is much 
darker brown, the white markings being clearer and more extensive. Orbicular stigma has no central dot, 
whilst in the type it often has a distinct dark centre. Wing expanse: 31—32 mm. Sutshan. 
76. Genus: Proxenu sH.-Schdff. 
This Genus should now be separated from Athetis. According to Filip jev's investigations the uncus 
is completely missing in the A genitalia, whilst in the Athetis species it is well developed. As stated already 
under Athetis , the following species should now be classified under Proxenus: lenta Tr. (= furvula Hbn.), fu- 
nesta Stgr., gluteosa Tr. 
P. bicolor Chret. Forewings yellowish white in basal quarter with a black basal costal spot therein 
and a second one in the first quarter; the whole of the rest of the wing is bluish black with 5 apical costal 
dashes and a heavy irregular spot at close of cell. The spotted edge of the posterior transverse line and subterminal 
line with 5 marginal dots, are yellow white. The subterminal area is slightly peppered with yellowish white. 
Both transverse lines are delicately black. Hindwings white, brownish at apex with fine brown marginal line. 
Head grey intermixed with yellow and black, the thorax is ochreous yellowish, scapulae yellow-white, abdomen 
deep ochreous yellow. Wing expanse: 18 mm. Biskra in March. This small species is unknown to me and 
I am therefore unable to judge whether is should actually be placed here. 
77. Genus: ISaclinogoes Btlr. 
R. subargentea Car. (= hospes Graes., nec Frr., tristis lugens Herz nec Stgr.) (21 k). Head and ab¬ 
domen very pale grey, thorax grey-brown, darker in $. Wing contour more elongate than in the closely related 
lepigone. Forewings monotonous pale grey-brown, darker dusky brown in $. Reniform stigma is merely in¬ 
dicated by a faint white streak, the dentate transverse lines are very indistinct, the median area is occasionally 
faintly darker. Hindwings pale grey with slightly darker veins. Wing expanse: 26.5—-31.5 mm. Amur terri¬ 
tory, Corea. 
R. v-parvum Kozh. has similar wing contour to lepigone (Vol. 3, p. 216, pi. 45 i) but the apex is less 
rounded. Forewings pale grey-brown, both transverse lines very indistinct, paler than ground colour, con¬ 
sisting of small lunules, the posterior line proceeds straight from apex to the outer third of inner margin and 
it has a dark shade outwardly, there is then a narrow pale band that does not extend to apex. Margin and 
central area are somewhat darker and with a more rufous tinge. Basally there is a short pale longitudinal 
stripe below the mediana. Orbicular stigma is a small brilliantly white v-slmped mark. Reniform stigma is 
a white dot. Hindwings pale grey with darker veins and narrow dark margin. Wing expanse: 28 mm. From 
around Minussinsk, flying by day over steppes where Artemisia grows, in May. 
R. cinerea Alph. (Vol. 3, p. 21(5, pi. 48 d) has a certain resemblance to subargentea, but the apex of 
forewings is less rounded off and central area more clearly outlined. A transverse band of small longitudinal
