384 European Buttkri'lies and Moths. 



middle, and with nearly uniform rounded projections on each side, nowhere remarkably- 

 prominent ; the double stripes distinct and pale grey, the subterniinal line filled up with 

 darker on cells 3 to 6 ; hind-wings with the costa considerably longer than the inner margin, 

 pale grey, witli the light band simply curved, and nervule 5 rising from the hinder half of 

 the discocellular nervule; antennae of the male not pectinated. Expands from \\ to \\ inches. 

 Inhabits the mountains of Northern and Central Europe, the Altai, and Labrador, from May 

 to August. The larva is greyish-green, with triangular reddish spots on the back, bordered 

 with black. It feeds on bilberry and heath in May and June. 



*8o. L. F lavic'uutata (Hiibn.). — Resembles Ccesiata, but the wings are more strongly 

 dusted with golden-yellow, and the central area is of a more decided bluish-grey colour ; the 

 hind-wings are rounder, with the costa and inner margin of equal length, and nervule 5 

 rises more in the middle between nervules 4 and 6. Size of Ccesiata. It is found in the 

 mountains of Northern and Central Europe in July. The larva closely resembles that of 

 Lccsiata, but is of a duller green; it feeds on saxifrage in May. 



81. L. Iiifidaria (Lah.). — Resembles the last two species, but more strongly dusted with 

 golden-yellow, especiall)- at the base, on the sides of the central area, and on the nervures in 

 the marginal area ; the projections of the central area are longer and more pointed, and the 

 hind-wings resemble those of Flavicinctata ; nervule 5 rises from the hinder half of the disco- 

 cellular nervule. Size of Ccesiata. Inhabits the mountains of Central Europe in July. 



82. L. Cyanata (Hiibn.).— A narrow band at the base, and the central area of the fore-wings 

 bluish-grey, a broad band before the middle, and the marginal area whitish, or more or less 

 dusted with golden-yellow, the central area not sharply defined, with regular projections, and with 

 no central spot ; the double stripes and the subterminal line wholly suffused, and the marginal 

 dots only distinct on the hind-wings, which are equally long on the costa and on the inner 

 margin ; nervule 5 rises from the hinder half of the discocellular nervule ; antennse of the 

 male not pectinated. Expands about li inches. Inhabits the Alps and the Riesengebirge 

 in July. A scarce and rather variable species, but not difficult to recognise. 



83. L. Topliaceata (W. V.). — Fore-wings ashy-grey, with the central area darker, especially 

 on its hinder edge, where it is intersected by dark lines, and somewhat suffused with yellowish ; 

 there are two strong projections in the middle, above which it is more retracted than in the 

 other species, and there are one or two slighter projections below the costa ; the first 

 double stripe is only distinct in front, and the second is whitish ; the nervures in the marginal 

 area are yellow, and the subterminal line is shaded with dusky on both sides above the middle 

 and on the costa ; hind-wings with the costa and inner margin of equal length, grey, with a 

 light double stripe and subterminal line, the former forming a rectangle, and the antenna; of 

 the male not pectinated. Expands from i^ to i^ inches. Inhabits the mountains of South- 

 Central Europe in July and August. 



*84. L. Salicata (Hiibn.).— Fore-wings dusted with bluish-grey, the base and sides of the 

 central area darker, and varied with yellow, as are also the nervures in the marginal area ; the 

 central area is shaped as in Ncbnlata, but has no dark spots on the border ; the double stripes 

 and subterminal line are indistinct and a little lighter than the ground-colour ; the hind-wings 

 are of equal length on the costa and inner margin, grey, with the double stripe beyond the 

 middle rectangular, but indistinct; the antenna: of the male are pectinated. (A variable species; 

 variety Podevinaria, Herr.-Schafif., is not dusted with yellov/.) Expands from 1 to ij inches. 

 Inhabits the mountains of Southern and Central Europe and Syria in May and June. The 

 larva is flesh-coloured, with the lines edged with reddish, and a row of brown or rosy spots
