 with fragments of moss, which remain green.

 body and more rounded wings, which are only whitish at the base, being dark grey distally. Length of fore- 

 wing 8 mm. 9 above honey-brown, head and thorax light wax-yellow. — Larva with blackish thoracical 

 plates. Case very slender, asymmetrically covered witli fragments of wood. — Flies in April and May in Central 

 Italy (Rome, etc.). 



H. lucasi Trautm. (55 c), from Algeria, differs from wockei in being somewhat smaller, the thorax lucaH. 

 without any white hair, the fringes somewhat longer, the bases of the wings more pronounced yellow, 

 the antenna longer (almost reaching to the discocellular), the pectinations somewhat longer and more densely 

 ciliated, the hair of the abdomen longer, and in the larva-case being covered with thin broad leaves of grass 

 and otherwise similar to that of Oreopsyche kahri Led.

with the exception of the anal angle of the hindwing, which bears long white fringes. $ whitish yellow, brown 



anteriorly. The J flies in the afternoon, January — March, in Andalusia. The case is covered with grains 



of sand and bears single dry vegetable fragments; it is slender, 7 — 9 mm long, and found on low herbage 



in Pine-woods. — abencerragella Mill., from Castilia, is still darker, being blackish. ahencerm-

9. Genus: Oroopsyclic Speier. 



Very closely related to the last genus, but the wings more elongate, more abundantly scaled and dark 

 in colour. The larva-cases are very different in the different species.

 species, forewing 12 mm long, with the wings very elongate and smoky grey, and the antenna long and strongly 

 plumose. The abdomen is characterised by the long hair being parted, and extends only a little beyond 

 the anal angle of the hindwing (cf. O. biroi Rebel). 9 pale yellow, thickest in centre. ■ — Larva wine-red, head 

 white, thoracical segments white with black streaks. The case widened in middle, transversely covered 

 with grass-halms and outside them with a thin white web. 



0. pyrenaella H.-Schdff. (= tabanella Brd.) (55 e), from the Pyrenees, resembles the previous species, pyrenaeUa. 

 but is smaller, the forewing measuring 8 mm in length; the entirely transparent and strongly glossy wings are 

 strongly romided, the costal margin and fringes of the forewing being black and its vems brown. Antenna 

 ])rown-black; hair of body black or brown-black. $ not known. — Larva polvjjhagous ; on Juniperus 

 communis, Calluna vulgaris and particularly Vaccinium uliginosum and mj^rtillum. The cj-case is almost 

 cylindrical before pupation, later globular, and irregularly covered with small fragments of stalks. — albescens albescen.<i. 

 Oberth., from the Centi'al Pyrenees, is larger, the wings have a milky white tone and shorter fringes, which 

 are grey instead of black. 



0. tabanivicinella Brd. (55 c) is larger (length of forewing 9 mm) witli the wings more pointed than in tabanivir-i- 

 ■})i/re)i(ielln. The wings have a reddish brown tone and black fringes. The brown-black antenna is relatively "e^In. 

 short. Body with dark brown hair, but the hairs paler at the tips. • — Larva wax-yellow, with black-brown 

 head, the thoracical plates likewise black-brown, with yellow markings. It is polyjihagous, but feeds particu- 

 larly ou Cnrlinn ncuulis. is full-grown the end of September, but pupates only the next spring; on the wing 

 the end of May and in June. The case is 22 — 2J: mm long, cylindrical, slightly rounded-incrassate at both 

 ends, similar to that of pyrenaella, but covered with shorter and less raised vegetable fragments. — Southern 

 France. 



0. biroi Rebel, from Croatia, is closely related to vesubiella, but the antenna and its pectinations are hiroi. 

 longer, the upper angle of the cell of the forewmg is less pointed and does not project so far beyond the 

 lower angle, its distance from the wing-apex equalling about one-third the length of the wing, while the 

 distance is only one-fourth the wing in vesubiella. Moreover, veins 6 and 7 (and 8) of the forewing branch 

 off separately, while they originate from a point in vemihiella. In the hindw ing the upper discocellular is verti- 

 cal to the costal margin, in vesubiella however directed obliquely forward and outward. Forewing 10 mm 

 long. On the wing at the end of June. — DiiievfiivomO.leschenaulti in its larger size and longer pectinations. 



0. kahri Led. (55c). (J: Forewing with the distal margin strongly oblicpie and convex and about as kahri. 

 long as the hind margin; the hindwing narrower, evenly covered with blackish scaling; both wings somewhat 

 paler at the base. Head and body very shaggy black-brown, the frons with grey hair; the hair at the apex 

 of tlie abdomen projects in the shape of two divergent thick tufts directed backwards. Antenna very plumose, 

 with irregularly arranged, very strong pectinations. Length of forewing 7 — 8 nnn long. $ and larva not known. 

 — Case 12 mm long, irregularly covered lengthways with broad fragments of stalks. — Calabria and Sicily.
