S. standfussi Wocke, nec H.-Schaff. (Vol. 2, p. 362, pi. 55 f). — kurenzovi Filipjev (14 i) from Sutshan, kurenzovi. 
Ussuri. Of the same size as a small to medium S. standfussi ; wing expanse 24.5 mm; width of fore wings 
7 mm, length of same 13 mm, width of hindwings 6.5 mm. Pectinations of antennae abt. 5 6 times longer 
than the shaft, narrower and less thickened towards the free end than in hirsutella, more similar to stand¬ 
fussi than to hirsutella Hbn. Somewhat wider in the wing than the former, agreeing with same however in 
colouration of wings and body. Genitalia like those of hirsutella, remarkably robustly built, relatively larger, 
dimensions as in standfussi. Flight from mid June to mid July. A paratype before me is of the same size 
as my largest hirsutella. We are illustrating the paratype of kurenzovi. — sajanella Kozh. from the Sajan sajanella. 
mountains and contrastella Kozh. from Minussinsk, Siberia are held by Filipjev to be identical with kurenzovi. contrastella. 
I have the originals before me. The specimen of contrastella has completely lost the abdominal hairs, so that 
the pale brown chitinous body is visible, that of sajanella has grey hairs. Other differences with the exception 
of small variations in the size, are not observable. 
16. Genus: Cochliotlieca Rmb. (Apterona Mill.). 
C. helicinella H.-Schaff. (Vol. 2, p. 363, pi. 55 f) is mentioned by Heylaerts as also occurring in Algeria, helicinella. 
Oued-Ounet. It is not rare at Taormina and Syracuse, Sicily and I have abt. 40 $$ and over 100 casings 
ex coll. Trautmann from there. 
C. gracilis Spr. (Vol. 2, p. 363, pi. 55 g). I have a large number of identical specimens from N. Africa, gracilis. 
Guelt-es-Stel and El Kantara, Algeria, captured 20—28 May. Hitherto in Spain the species was only known 
from Andalusia and Aragon, but its distribution extends to Catalonia, Montserrat, where I captured 2 ES 
at night at light on the 29th July at an altitude of 1100 m. The moths are attracted to a light-sheet at 
night. The casings have so far not been described. The q measures 4 mm in width and 4 mm in height. 
It resembles that of crenulella, but is coarser and covered with rougher particles of sand and earth. The? 
sac is much larger and also longer than in the other species, measuring 6 mm, wide and up to 9 mm long 
with distinct spirals. — pectinata Chret. according to information kindly supplied by Mr. Lhomme, is not to be pectinata. 
found in the coll. Chretien ; it was therefore not possible to supply me with a specimen. It was captured by 
Allttaud at Haute-Reraya in the Grand Atlas. According to the description of the only known, the 
wing colouration is very like C. crenulella Brd. (Vol. 2, p. 363, pi. 55 g) differing however by the long pecti- 
ations of antennae, which are almost longer than those of nylanderi Wrli. ( pusilla auct.). The transparent 
wings are yellowish brown, costa dark brown in basal half, fringes paler than the wings. Head and body 
black-brown, with white hairs. M ing expanse 13 mm. Is probably closely related or even identical with 
C. gracilis. 
C. powelli Oberth. (141). Was described as a Sterrhopteryx , represents the largest of all known Cochlio- powelli. 
theca species, having a wing expanse of 14—15 mm. It is compared to S. hirsutella Hbn. and Metisa plana 
Wkr. (Vol. 10, pi. 91 b) from Ceylon. Actually however it is nearer to C. gracilis Spr. (Vol. 2, p. 363, pi. 55 g), 
differing only by its much larger size, slightly darker grey, more heavily haired and rounded wings, which 
have a somewhat more convex shape. The antennae are rather more robust and have wider pectinations 
and the head has longer grey-black hairs. Abdomen is frail with paler hairs than wing colour. Perhaps when 
the ? is discovered and the early stages are known, this will prove itself to be a race of C. gracilis. Mrassine, 
Morocco in May; Sebdou, Oran, whence a good series of $3 has been recorded. 
C. stauderi Wrli. (14 i [Type]) was discovered by Staltder on the 7th July 1920 near the summit of stauderi. 
the Aspromonte, Calabria. In general appearance and colour it is like C. nylanderi Wrli. ( pusilla auct.) (\ ol. 
2, p. 363) (14 i) which hitherto has only been known as definitely occurring in the Pyrenees, but it is con¬ 
siderably smaller, with a wing expanse of 9.5 mm as against 13—14 mm of nylanderi. It is also a deeper 
black. Antennae pectinate as in the latter but frailer. Pectinations wider at tip, shorter at base and gener¬ 
ally shorter than in nylanderi, black. Fringes slightly paler and long, longer than in nylanderi. The 3 
median nervures, which are separate in nylanderi , appear to arise from a short stalk. 
C. pusilla Spr. (Vol. 2, p. 363, not illustrated there) (14 i) is described from a somewhat worn from pusilla. 
Constantine, Algeria. Wing expanse barely 12 mm. As Speyer expresses himself, it reminds one much more 
of a small Epichnopterix pulla (Vol. 2, p. 366, pi. 55 g) than the typical G. helicinella (Vol. 2, p. 363, pi. 55 f). 
Wings are somewhat narrower, less rounded at the angles than in the latter. Colouration is a weakU pale 
grey whilst body is a fairly deep black. ? and early stages unknown. Several specimens before me agree 
exactly with this description of Speyer. They were captured by Dr. Roch of Geneva, in Morocco on 2Sth 
March 1923. They are distinguishable by the narrower, more elongate wings and as compared with helici¬ 
nella H.-Schaff. from Sicily and nylanderi Wrli. (14 i) from the Pyrenees, they have a deeper colour. The 
inner angle of wings is more obtuse and less pronounced than in the latter. Rothschild mentions a
