368 BACOTIA ; LUFFIA. By Dr. E. Strand. 



stalks of grass and fragments of wood, which are raised behind; 12 — 14 mm long and relatively thick; found 

 on the sunny side of rocks and old wails. Flies the end of May and in June in South Europe and Southern 

 Central Europe, in England, Koumania, and questionably Livonia. 

 casta. F. casta Pall. (= nitidella Hbn., intermediella Brd., roboricolella Brd. (^) (55 i) is smaller (forewing 



6 — -7 mm long) and more uniformlj^ aenescent-brown than the preceding species. $ reddish brown, above 

 darker, with luteous grey anal wool (white according to other autliors). Larva smaller and its black-brown 

 head -with less distinct markings than in the preceding insects; on herbage and deciduous trees. The case 

 also is smaller than in F. crassiorelh, 8- — 12 mm long, up to 3 mm broad, and covered with thinner stalks, 

 which are placed close together. — The commonest European species and probably distributed tliroughout 

 Europe, also in Asia Mmor and Algeria, questionably in Amurland and China. 

 rouasti. F. rouasti Heyl., from the Ala Tau, is said to have the wing-contour of Bacotin sepiutn, but to come 



nearest to F. betulina in neuration. Antenna grey, the pectinations shorter than in hetulinn. Wings smoky 

 grey with white fringes. Forewing witii a long cell in the cell. Thorax and abdomen black, with the hair 

 grey. Legs grey. Expanse 12 — 14 mm. 

 betvdina. F. betulina (= roboricolella Brd. $, anicanella Brd., 1 salicolella Brd.) (55 i). Forewing narrower and 



longer than in F. casta, more pointed at the apex, uniformly aenescent, with darker veins, 6^ — 7 mm long. 

 The pectinations of the antenna thinner, not scaled. Head, thorax and abdomen uniformly dark brown. A 

 dark discocellular smear visible on the forewing. $ brown-red, black at the sides, with snowy white anal wool. 

 Larva as in casta, but the head deep black and without markings. The case is covered with small fragments 

 of leaves and lichens, rarely with some stalks. The species resembles Bacotia sepium very much, but differs 

 inter alia in the presence of a cell in the cell, whereas B. sepium has an areole. ■ — In Central Europe, 

 England, Western Russia, Sweden, Roumania and Amurland. 

 eppinyella. F. eppingella Tutt (= anicanella Chapm., ?? salicolella Brd., H salicicolella aut.) (55 i). Under the 



name of saUcoleUa Brd. (usually written salicicolella) a very doubtful species has been known which is said 

 to differ in the ^ from F. betulina in the somewhat larger size and whose $ is said to have brownish 

 grey anal wool. I have also arrived at the same result as Tutt, namely that this species of Bruand's can 

 scarcely be different from betulina, whereas the insect described by Tutt as F. eppingelh from England, but 

 also occurring in France, is probably a distinct species differing from betulina in the following points: Antenna 

 with 26 segments (in betulina 21), wings shorter, more rounded at the end, with the distal margin less oblique; 

 wings scarcely distinguishable from those of casta in contour and colouring. The case is said to be nearly as 

 broad as it is long and to be covered Math fragments of dry leaves which do not lie close together. Pupa smaller 

 than in betulina. 



24. Genus: Baeotia Tutt. 



The pectinations of the (J-antenna commence on the fourth segment, i. e. on the second of the shaft. 

 The spur of the fore tibia is short. 5 with divided dorsal plates on the abdominal segments. Larva dark, 

 blackish, with black-brown dorsal plates divided by a pale median line on the two first thoracic segments, 

 while the third segment only bears two small plates widely separated from one another. Case bell-shaped. 

 (Cf. the following genus for further characteristics.) 

 septum. B. sepium Speyer (= tabulella Guen.) (55 i) has very elongate and pointed wings which are aenescent- 



brown, have a yellow sheen and bear sometimes light watermarks; a darker discocellular smear present; 

 forewing 6 — -7 mm long (cf. also Fumea betulina). $ dark brown, yellowish at tlie sides, with yellowish grey 

 anal wool; head brown, with large black eyes. Larva hibernates and feeds chiefly on the lichens of Gymno- 

 sperms. — In Central Europe, Western Russia and Roumania; flies in June and July. 



25. Genus : liuffia Tuft. 



Differs from the previous genus in that the first pair of pectinations, situated on the fourth antennal 

 segment, are very short, vein 1 c of the forewing is always distinct basally (vestigial in Bacotia), and in that 

 the cross-vein between veins 5 and 7 of the hindwing is straiglit (angulate in Bacotia). The $ sometimes 

 parthenogenetic. Larva on lichens of rocks. 

 lapidella. L. lapidella Goeze (= lapicidella Zell., lapicidella Guen., pectinella Dup., ? pinastrella Mill.). (^ 



dust grey, with pointed wings and long, irregularly arranged, antennal pectinations. Forewing indistinctly 

 reticulated, 4 — 4.5 mm long, with vestige of a darker discocellular smear. $ brownish, with yellowisli grey 

 aiial wool, antenna with 14 segments. Larva blackish grey, with blackish brown head and lighter plates on 

 the two first thoracic segments, wliile the third segment only bears two small brown lateral plates. The case 

 at first cap-shaped and 5 — 6 mm long, later on narrowed towards its upper end. — In Southern Spain, 

 Switzerland, France, England, Corsica, Italy, Dalmatia and the Canaries. 

 ferckaulleUa. L. ferchaultella Steph. appears to be the parthenogenetic $ of the preceding insect; it differs from the 



$ of lapidella in its smaller size, darker colouring, more strongly curved claws and the 12-segmented antenna. 

 — England ( ?), France, Switzerland and questionably also Italy. 

 maggiella. L. maggiella Chapm., from theTessin, is distinguished from L. ferchaultella. only in that it is not parthen- 



ogenetic. Antenna Avith 12 segments. ^ not known.
