Larextia. 383 



liind-wings rather long, the costa longer than the inner margin, and the basal half almost 

 rectangular; antennae of the male pectinated. Expands about ij inches. It occurs in the 

 Austrian Alps in June. 



75. L. Adumbraria (Herr.-Schafif.). — Fore-wings pale grey, dusted with brown, the second 

 double stripe whitish towards the costa, the central area with a dusky band behind, intersected 

 by two darker lines, and projecting more strongly in the middle ; the subterniinal line suffused, 

 and the hind margin marked with a row of double black dots ; hind-wings with the costa 

 and inner margin of equal length, with a light, simply curved transverse band ; antennas of 

 the male not pectinated. Expands about li inches. Inhabits Dalmatia and Armenia. 

 The larva is believed to feed on Pinus abies. 



76. L. hicultaria (Herr.-Schaff). — Fore-wings with the tips pointed, uniform pale shining 

 grey, with two broad whitish double stripes, the second with slight projections in the middle, 

 the central area twice as broad on the costa as on the inner margin, and with large brownish- 

 grey spots on both sides towards the costa ; the subterniinal line and the hind-wings whitish, 

 the latter almost without markings, and the antennae of the male not dentated. Expands 

 about I inch. Inhabits the Alps and Galicia in July. The larva is green, and mines in 

 the leaves of Primula Aiiriaila among the rocks. {L. Senectaria, Herr.-Schafif., from Croatia, 

 has yellowish-grey fore-wings, darker on the hind margin, with dark transverse stripes, the 

 double stripes not lighter, and indistinct ; hind-wings whitish. Expands about i^ inches. 

 L. Sandosaria, Herr.-Schaff., from Andalusia, has the wings very slightly festooned, and 

 bordered by double black oblong dots ; fore-wings pale rose-colour, with the base and central 

 area browner, the latter traversed by three lines, in addition to those bounding it, all of which 

 are waved and dentated, and the space between the two first and the three last is dusted 

 with grey, and marked with a central spot. The subterminal line is slender, pale, and dentated, 

 and there are some traces of other lines. The hind-wings are rather greyer than the fore- 

 wings, and marked with many parallel lines. It occurs in April.) 



TJ. L. Nebulata (Tr.). — Fore-wings pale grey, the base and central area darker, the 

 latter intersected by two darker lines ; its hinder edge is marked with small dark spots on 

 the nervures, and forms a triple pointed projection in the middle, and a bi-lobed projection 

 between this and the costa ; the double bands are whitish, the second suffused outside ; hind- 

 wings with the costa and inner margin of equal length, with the basal half darker, and 

 forming almost a rectangle in the middle ; nervule 5 rises from the hinder half of the 

 discocellular nervule, and the antennae of the male are not pectinated. Expands from \\ to 

 \\ inches. It is found in the Alps in July. {L. Ibcricata, Staud., from Spain, is pale grey, 

 dusted with brown, with the commencement of several pale brown lines on the costa of the 

 fore-wings, only the intermediate ones extending to the inner margin ; hind-wings with the 

 nervures brown, and an angulated pale brown central shade. Expands about i inch.) 



78. L. Aclirouiaria (Lah.), Saxicolata (Led.). — Resembles Ncbulala, but smaller; the 

 projections of the central area are rather more pointed, and the dark dots on its hinder 

 margin are less distinct ; the discocellular nervule of the hind-wings is very slightly curved, 

 and nervule 5 rises from the middle. Inhabits the Alps. (Z-. Polata, Hiibn., from Lapland, 

 Labrador, and Greenland, is intermediate between Casiata and Austriacaria, and may be 

 recognised by its silky appearance, its dark shade, and by the regularity of the pale band 

 beyond the central area, which is darker, and very neatly intersected by transverse lines.) 



*79. L. Ccesiata (W. V.). — Fore-wings bluish-ashy, sometimes slightly dusted with yellowish, 

 with darker transverse lines ; the central area brownish-grey, lighter on the costa in the
