liair and therefore semitraiispareiit, the distal margin of the forewing oblique, the innd angle broadly rounded. 

 Legs shaggy, fore tibia with spine, hind tibia without spurs. $ and larva very similar to those of Ganephora 

 and Pachythelin. 



A. quadrangularis I'hriNl. is large (expanse 24 — 28 mm): the wings whitish, sem transparent, more .[uadramju- 

 or less dusted witli grey, with the costal margin darker. Fringes of both wings blackish. Hair of body long, '"*■*«• 

 dense and white. Abdomen extending far beyond the anal angle, black, the hair being partly white. Forewing 

 elongate, with rounded apex. $ naked, black, only woolly at the anus, this wool being white, length 14- — 18 mm. 

 The ca.se 35 — 40 mm long, composed of almost parallel, transversely placed bits of stalks which are so regularly 

 arranged in a quadrangular shape that the four corners are almost mathematically exact right angles. Each 

 side measures about 8 — 9 mm in width, the c?-case tapering but little, the $-case considerably more. On the 

 inside the case is lined with white silk, and the four cornes split open when the ^ emerges. The dirty yellow- 

 ish white larva is 30 mm long, feeds on Alhagi, Artemisia, and Peganum, and bears markings and is colou- 

 red on the posterior segments as well as the anterior ones. Pupa of c? dark brown, of 9 slightly. paler. The 

 species inhabits steppes, flies in August and September, and is recorded from Egypt and Algeria. The Egyptian 

 form (= murina Klug) however, is perhaps constantly different from the main form. The Berlin Museum 

 contahis a number of larval cases labelled as follows: everywhere near Biskra on small thornbushes, chiefly 

 Zizyphus lotis, in February. Other cases from the same place bear the remark: ,,The Psychid cocoons are 

 constructed of stalks of Pithyranthus scoparia C. D., Thymelaea microphylla C. D., Antirrhinum ramosissi- 

 muni C. D., etc." (G. Schweinfurth). — Staxjdinger has described from Ordubad in South-Eastern Trans- 

 caucasia as nigrescens (55 a) a form with blackish, seraitransparent wings and black abdomen. — ■ From nii/rcsixns. 

 Palestina a pale whitish grey form, albescens Stgr. (55 b), has been recorded, in which only the costal margin albescens. 

 of the forewing remains dark; size larger, expanse 32 mm. — murina King. Only 1 specimen before me, miirma. 

 Klug's type; as far as can be judged from this old example (which, however, is rather well preserved), murina 

 differs from the original description of "Psyche quadrangiilaris Christ." in the following points: The body 

 is not black, but pale brownish; the scaling at thfe costal margin of both wings brown, not black, the fore- 

 wing less elongate resp. its distal margin much less oblique, the wing therefore appearing broader at the 

 apex; also the hindwing broadly rounded at the apex and broader than the forewmg. The wmgs are also 

 broader at the apex with less oblic(ue distal marghi than in Hyalina alhida Esp., whereas quadrangularis 

 differs from alhida inter alia in the "more elongate wings". The hair of the whole body is dirty yellowish 

 white, only being somewhat darker in the face. The fringes brown grey on the forewing and brownish yellow 

 on the hindwing. Veins without darker scaling. The anterior portion of the body, also apart from the hair, 

 is almost twice the width of the abdomen, which latter extends but little beyond the hindwing. Veins 4 and 5 

 of forewing on a long.stalk, but the stalk shorter than the free ends. Moreover, the legs are not black. Expanse 

 27 mm., length of forewing 12 — ^13 mm, length of antenna 7 mm. 



A. cabrerai Rebel (55 b), from the Canaries, is sooty brown in the ^■, the antenna reach to one-third cahrcrai. 

 of the costal margin and have about 25 distinct segments, the branches being strong and, towards their 

 apices, incrassate. Body and legs covered with smooky brown woolly hair. The spurs of the hind tibia are 

 small. The abdomen does not extend beyond the anal angle of hindwing. The fringes have a feeble reddish 

 broWn flush. Length of forewing 5.8 — 7.2 mm. — Larva in the spring on Euphorbia. The cases on Tamarix 

 canariensis, in facies like those of quadrangularis, up to 12 mm long and 3 mm broad. The pupa of the 

 (J G mm long. Moth in August^ — September. 



A. sera Wish. (55 b) (= heylaertsi Mill.). The (J resembles hitea, but is smaller and darker, with scm. 

 more rounded wings and slenderer antenna. Length of forewing 10^ — ^11 mm. $ clothed with a whitish 

 wool. — In the mountains of Central Italy and Sicily, in August. — The larva biennial, until July; head and 

 nuchal plate brown with black punctures, the dorsal plates of meso- and metathorax divided by a light me- 

 dian stripe and laterally spotted with yellow. The larva-case is 25 mm long, brown, irregularly covered with 

 bits of leaves and stalks. 



A. tedaldii Heyl. (55 b). (^ yellowish smoky brown, densely hairy, abdomen not extending beyond anal ledaldii. 

 angle of hindwing. Forewing densely scaled, elongate, 11 mm long. Hindwing shorter and more rounded. 

 — The larva-case elongate, tapering towards the apex, covered with leaves and shells. 9 riot described. 

 Both sexes emerged (Algerian .specimens) the end of August (according to Oberthur). This form, which 

 is perhaps not specifically distinct from sera, is recorded from Sicily, Algeria, and Syria. 



A. lutea Stgr. (55 b). ,^ uniformly yellowish grey. The pectinations of the antenna gradually decrease lutea. 

 in length. Abdomen strongly pointed. Length of forewing II — 12 mm. July — ^August. Italy and Sicily, 

 Greece, Western Asia, and Algeria. Larva 20 mm long, dirty yellow, head and thoracical plate light yellow 

 with black markings. The larva-case as in febretta, but the stalks of grass are irregularly arranged. — armena armena. 

 Heyl., from Armenia, is darker, but has whitish pseudopalpi and stronger antenna; the tibial claw reaches 

 to the middle of the first tarsal segment, while it is not longer than the tibia in true luiea as well as in 

 shahkuhensis. — shahkuhensis Heyl. is still darker than armena, and also stronger in build; the branches of shahkuhen- 

 the antenna much longer, the hair of the body long, the fringes brownish. In North-Eastern Persia. ■"*■
