nigricans. 



300 OREOPSYOHE. By Dr. E. Strand. 



pectinations of the antenna shorter than in O. pyrenaella. Forewmg 9 mm long. ? amber-colour. The (J-case 



12 14 mm long, tubuliform, slightly incrassate in the middle and sonwnvhat curved at the upper end; the $- 



case 20—22 mm long, strongh' incrassate in the upper two-thirds, slightly curved and tapering at the lower 

 end. The case is always composed of agglutinised grains of soil and sand and bears a great resemblance 

 to the cases of Talaeoporia and Rebelia. Larva whitish yellow, with tlic head and thoracic plates blackish, 

 the latter marked with white. In the higher Pyrenees, in July. — nigricans Stgr. (55 d), from Central and 

 Northern Spain, has the wings and hair darker. 



sili)hcJla. 0- silphella Mill. (55 d) comes close to leschenauUi, but the forewing is more elongate with more pdinted 



apex, and both wings are much darker with more thickly scaled veins. Hair of body black. Forewing 8 mm. 

 long. 9 yellowish white with the head and thoracical plates darker. Larva on Dorycnium, whitish with 

 blackish head and thoracical plates, the latter with few markings. The case similar to that of leschenauUi, 

 but longer (o •** — -0 nim). often of a reddish colour, and strongly curved before the anal end. ■ — South-Eastern 

 France and Piedmont. 



7mis:eUa. 0. muscella F. (55 d). Wings strongly glossy, hyaline, with the veins, margins and fringes darker. 



The hair of the body long and black. The abdomen hardly extends beyond the anal angle of the hindwing. 

 None of the veins stalked, as is also the case in the previous species. Forewing 9 mm long. 5 brownish yellow, 

 with brovm dorsal plat' s, bent ath grey. Larva black-brown above, with the head and thoracical jjlates glossy 

 black, and with short hair; on grasses. The larva-case is widened in the middle, covered with dry stalks of 

 grass lengthwise, and usually fastened on the ground. Widely distriituted in Central Europe, also found m Ar- 

 sicheliella. menia. On the wing in May between 9 and 11 a. m. — sicheliella Bid. (55 d) is very close to niuscella and 

 probably not specifically distinct. The wings, however, are strongly darkened in the basal area; the fringes 

 black and prolonged towards the anal angle of the hindwing. The neuration of the forewing is said to agree 

 closely with that of niusceUa, and that of the hindwing with Hyiilina iilbifla. The expanse is stated in the 

 text to be 18.5 mm, but the figure measures at least 20 mm. • — Southern Italy. 



fulminrlUi. 0. fulminella Mill. (55 d), from Castilia, is smaller than 0. muscella (forewing 8 mm long), and its 



wings ;i,rc less glossy, more rounded and more brownish. On the wing in May. Larva whitish, with the head 

 and thoracical plates black, the latter with pale markings. The case is covered with fragments of leaves 

 touching one another and appearing to form a second tube. $ not known. 

 (jondehau- 0. gondebautella Mill. (55 d) differs from the last species inter alia in that the two veins between 



tella. -^yiiici, iit>s the apex of the forewing are on a very short stalk, while they originate from a point in fnhninella; 

 moreover, the distal margin of the forewing is more convex and the apex more broadly rounded, and both 

 have a duller a))pearance, more greyish black, without prominently darker fringes. Is also very closely related 

 to O. plumijcrd O. Forewing 7 mm long. $ yellowish with black head and dark thoracical plates separated 

 at the joints by a pale colour; the body otherwise clothed with white wool. Larva incrassate in middle, 

 with black head, thoracic plates also black, separated at the joints by a pale colour. Feeds on grass and 

 hibernates. The case is 12 mm long, not very slender, covered with moss, rather irregularly and length- 

 ways. — ■ Central and South-Eastern France, Lyons (Mus. Berlin). 

 muiiitsleUii. 0. angustella H.-Schdff. (= atra Esp.. stomoxella Bdv., hirtclia Bnl.). ^ characterised by the long, 



narrt)W, almost elliptical wings, the hindwing being much the shorter, and by t he abtlomen extending far beyond 

 the anal angle, and bemg clothed with long hair parted in brushes. The wings glossy, transparent, blackish 

 the veins not stalked. Forewing 1- — 8 mm long. The ? 14 mm long, reddish yellow with darker head 

 and white-haired posterior segments. Larva with head and thoracical plates blackish, the latter being dotted 

 with white. The case is covered lengthways with dead grass-stalks and bears a great resemblance to that 

 of Psi/rliidca bomhycellit Schiff. In Southern Germany, Austria and France. On the wing in June-July. — 

 Ucolorcllu. bicolorella Bdv. (55 d), from the Pyrenees and ( I) Central Italy, when emerging has j-ellow wings, which be- 

 come black later on with the exception of the basal area. 

 plumifera. 0. plumifera 0. (= atra nut. nee L.. hieracii Thnnh. [ ?]. muscella Dtip., bellierella Brd.) (55 d). ^ 



similar to the preceding species, but the wings without gloss and of even width, the abdomen does not 

 extend beyond the anal angle of the hindwing, veins 6 and 7 of the forewing (IIIl and 115) on a short 

 stalk. $ brownish vellow. with darker head. Larva brownish with black head; thoracical plates likewise 

 black, divided by a pale longitudinal stripe. In March on grass and Thymus. The case is 11- — 13 mm long, 

 covered with short dry vegetable fragments (of lichens, Hypnum, etc.), in dry sunny places. The moth emerges 

 according to the locality, even at the end of February, and is said to occur sometimes in large numbers at 

 higher altitudes, e. g. in the Pyrenees, being distributed in Southern Germany, Austria-Hungary, in the north- 

 ern districts of South Europe, Portugal (Mus. Berlin), Armenia and the Tarbagatai district; the record 

 valcs-iella. from Southern Sweden is probably erroneous. — valesiella Mill, is a somewhat paler form from the Alps. 

 mediiev- — mediterranea Led. (= massilialella Brd.) (55 d), from Southern France, Berner Oberland, Italy, Turkey 

 ranea. (Mus. Berlin), Caucasus and Mauretania, is larger, the forewing measuring 9- — 10 mm, but otherwise like plu- 

 mifera; the statement by Bruand that the antenna has shorter pectuiations does not appear to be correct.
