is a dark and often macular centra! shade between them ; the subterminal line is straight and 

 edged outside with white ; the fringes are grey spotted with blackish, and the under side is 

 washed with black and crossed by a slender central line and marked with black central dots. 

 Expands a little more than i inch. Inhabits South Europe from April to June. The larva 

 is ochreous-grey or dull reddish, \\ith an indistinct brown line on the back edged with whitish, 

 and a brick-red line on the sides. It lives on Cistus Monspelieiisis in December. 



12. G. Tibiaria (Ramb.). — Fore-wings .shining greyish-brown and slightly striated, the second 

 line only is marked on the fore-wings by a pale streak which is twice arched, and b}- a row 

 of white dots on the nervures touching black dots ; hind-wings paler and without markings ; 

 the under surface is marked with black discoidal dots and a row of black dots across the centre. 

 Expands nearly i^ inches. It is found in August and September in open places in woods in 

 the centre of France. [G. Bcncsigiiata, Chav., found in the mountains of Corsica in August, is 

 dark yellowish-brown ; fore-wings with black streaks on the nervures in the medial area, and the 

 elbowed line represented by a row of very fine whitish dots ; hind-wings paler, and marked with 

 a central row of black dots. G. Gniiicraria, Staud., which occurs in Greece in June, has 

 ashy-grey wings irrorated \\ith brown, with central dots, which are less conspicuous on the 

 hind-wings, and a chocolate-brown submarginal band bc)'ond the middle ; the hind-wings 

 are slightly waved, and the under side of all the wings is yellowish.) 



D. — The antenitce of the male ciliated, the hind tibia: long, and not thickened; the hind 

 margins slightly waved, and the tips of the fore-wings rather rounded. 



*I3. G. Obfuscata (W. V.). — The male is dark grey, and the female pale grc)', dusted 

 with darker, with an indistinct central spot and subterminal line ; the fore -wings with two 

 blackish dentated transverse lines, and the hind-wings with one ; the forehead of the male 

 is dark brown, and that of the female is grey, and the body of the latter is rather thick. 

 Expands from if to 2 inches. It inhabits the mountains of Northern and Central Europe 

 and the Altai in July. The larva is grey, or pale ochreous, with dark angulated streaks, 

 it feeds on vetches. Genista, &c., in IVIay. 



E. — TJie antenna: of the male are pectinated, the hind tibice long and thickened; the fore-wings 

 entire, or very slightly waved, and the hind-wings waved, and strongly contracted above the middle. 



14. G. Dilucidaria (W. V.). — Wings pale grey, finely dusted with darker, with brown 

 central rings, the second line dentated, and darker brown on the nervures, and the sub- 

 terminal line suffused ; the first line only represented on the fore-wings, and the forehead 

 whitish. Expands about i-J inches. Widely distributed in the mountains of Northern and 

 Central Europe in July and August. The larva is rusty-brown, with a dark line on the 

 back, and a sulphur-yellow stripe on the sides. It feeds on low plants till May. The moth 

 is figured at PI. 50, Fig. 5. {G. Canitiaria, Guen., from the Maritime Alps, is whitish, much 

 resembling the pale variety of Piillata, except in its pectinated antennas. The lines are 

 indistinct, the second line bordered with white, and the rings are large. It differs from 

 Dilucidaria by its colour, its more dentated fore-wings, and its yellow forehead and antennae.) 



15. G. Serotiiiaria (Hiibn.), — Resembles Dilucidaria, but pale ochreous-}ellow, more 

 coarsely and transversely speckled with brown ; and the forehead is brown above. Expands 

 about I J inches. It inhabits the Alps in July. The larva feeds on a variety of plants. 



F. — Resembles Section E, but the hind tibia: of the male are not thickened, and the hind 

 margin of the hind-tvings is only slightly waved, and a little contracted above the middle. 



16. G. Sordaria (Thunb.). — Wings pale grej-, dusted with rusty-brown, with small brown 

 central rings, the second line brown, dentated, and darker orf the nervures, and with black
