the head ; pale primrose above and between, pale ochreous at the 

 sides and beneath. Antennae pale brown. Thorax and patagia pale 

 primrose. Anterior wings primrose colour, with an ochreous tinge, 

 and a pale ferruginous oblique streak on the dorsal margin, and 

 numerous paler markings along the costa. Costa pale ochreous, 

 irrorated with grey scales on the basal half ; the apical half mottled 

 with pale ochreous. Before the middle of the dorsal margin arises 

 the oblique ferruginous brown streak, which attains the middle of 

 the disk, and sometimes has one or two small castaneous spots on its 

 anterior edge. Within the anal angle, on the dorsal margin, is a 

 triangular brown patch. The dorsal margin is maculated with 

 brown ; apical margin narrowly ochreous. The pale portions of the 

 wing clouded with ochreous, and irrorated with grey atoms. Apical 

 scales and cilia pale primrose. Posterior wings very pale grey, 

 merging narrowly into pale fuscous at the margins. Marginal 

 scales whitish, with a pale fuscous tinge at the apex. Cilia whitish. 

 In fine specimens a few minute, slightly shining tufts of elevated 

 scales are visible about the middle of the wing. Abdomen drab ; a 

 pale primrose-coloured tuft at the apex. $ Exp. al. 7| 8 lin. An- 

 terior wings much paler and more mottled than in the tf ; costa and 

 dorsal margin maculated throughout with dusky spots, and the oblique 

 dorsal streak faintly indicated ; posterior wings darker. 



An uncommon insect ; variable in size, and also in the in- 

 tensity of its colouring and markings ; closely allied to L. alter- 

 nana, but is smaller, and has its anterior wings less mottled, and 

 the abbreviated streak narrower and more defined. 



The imago appears in May and June, and occurs at Darenth 

 Wood, near Dover, the Isle of Wight, in Devonshire, at Probus 

 in Cornwall, in Yorkshire, Cheshire, and other places in the 

 north of England ; also in the vicinity of Edinburgh, and at 

 Belfast in Ireland.
