and covered with fragments of plants laid lengthways. It is found in the south of France and 

 Germany. (Variety Bicolorella, Boisd., from the Pyrenees, is reddish at the base of the wings. 

 0. Siculclla, Bruand, fron: Sicily, is darker, with red palpi, but not red at the base of the 

 wings.) 



4. O. JSIitscella (W. V.). — Wings transparent, shining, with brownish fringes ; hind-wings a little 

 narrower than the fore-wings ; all the nervules separate ; the abdomen scarcely reaching beyond the 

 anal angle. Expands nearly three-quarters of an inch. The female is reddish-yellow, with brown 

 plates on the back. The case is covered with fragments of grass and moss. The larva is dark 

 grey, paler on the sides and belly, with black shining plates on the back, and lives on grass till 

 April. The female pupa is pale brown, with the back darker. The moth is common in France, 

 South Germany, and Armenia in May; and the male is figured at PI. 26, Fig. 9. (0. Scliiffer- 

 iniilleri, Stand., found in the Austrian Alps in July, has a smaller head, and the palpi and wings 

 are longer. Tlie female is reddish, resembling that of Psyche Unicolor, but more slender ; the head 

 and thoracic plates are blackish. The case is more slender than that of Unicolor, and covered with 

 fragments of leaves, &c. O. Fiiliiiinc/la, Mill., resembles Phuiwsella, but is a little smaller ; the 

 fore-wings are less angular, and the hind-wings less rounded ; the body and wings are uniformly 

 smoky, with no bluish reflection. The case is formed of a bunch of dry leaves of oak or box. It 

 inhabits Castile. O. SilphcUa, Mill., resembles FiibniiicUa and Lcsclunaitltii, but the wings are 

 longer, nearly opaque, and sooty-black ; the tip of the fore-wings is more pointed, and the fringes 

 and nervures are broader, and of a deep opaque black ; there is no trace of light hairs on the 

 body. The female is greyish-white, with the plate flesh-colour. The case is clay-coloured, and 

 long and cylindrical. The larva feeds on Plantago, Rinitcx, and Dorycniuin ; and the moth 

 appears at Cannes in April and May, in the evening. 



5. 0. PIiiDiifera (Ochs.). — Smaller than Muscclla, the fore-wings not shining, and nervules 

 6 and 7 rising from a common stem ; hind-wings narrower. The case is thickened, and covered 

 with bits of moss and sand ; the larva feeds on thyme. Common in the mountains of Southern 

 and South Central Europe in May. {O. Mcditcrranea, Led., from South France and Italy, is 

 smaller, with very long palpi, and semi-transparent wings. Female as in 0. Atra. The case 

 is covered with bits of wood. O. Gondcbaittclla, Mill., found at Cannes in early spring, is larger 

 than Plumifcra, with much longer wings, and the case is composed of fragments of moss, laid 

 one over another.) 



6. O. Phnnistrclla (Hiibn.). — Male dark brown, fore-wings rounded, hind-wings rather long, 

 of nearly uniform breadth, head with very long hair, abdomen extending to the anal angle. Size 

 oi Muscclla. Widely distributed in the Alps. 



7. 0. Teiiclla (Spey.). — Male with brownish-grey wings, fore-wings broad and rounded, hind- 

 wings broader behind, the head with shorter hair, and the abdomen extending as far as the

* 8. 0. Hirsutclla (Hiibn.), Fusca (Haw.), Colvclla (Ochs.). — Body rather slender, thinly 

 clothed with short yellow hairs, head small, eyes large, antenna with short pectinations, wings 

 semi-transparent grey, with the nervures darker. Expands nearly i inch. Female short and 

 worm-like. The case is constructed of transverse stalks and fragments of plants, irregularly

 in Jul)-. (C. Standfussi, Herr.-.Schaff., from the mountains of Silesia, is paler, with seven 

 nervures on the hind-wings instead of eight ; and nervules 4 and 5, and 7 and 8 of the fore-wings
