brown-grey, or ochreous-grcy, much marbled with paler, and sometimes partially 

 tinged with light rust-brown. From the costa, within the basal third, start two 

 short, dark, oblique bars, often showing only as spots. On the fold are two large 

 dark spots, apparently continuations of the interrupted costal bars, the second deci- 

 dedly before the middle of the wing. On the disc are two large dark spots, the first 

 just above the outer edge of the second spot on the fold, the second, crescent-shaped 

 when complete, beyond the middle of the wing. The colour of the spots, and of 

 the bars, ranges from bright rust-brown, through chocolate, to dark fuscous, and the 

 spaces between them are frequently occupied by clusters of pale scales. Towards 

 the hind-margin is a pale angulated fascia, generally more or less well-defined. At 

 the apex there is usually a dark spot, on either side of which the margins are 

 chequered light and dark. Cilia pale greyish-ochreous, sometimes more grey than 

 oehreous, often with traces of transverse fuscous lines. Hind-ioings but slightly 

 emarginate below apex, semi-transparent, satiny leaden-grey, veins darker ; cilia 

 pale greyish-ochreous, sometimes more strongly grey. 



Abdomen grey or greyish-fuscous above, greyish-ochreous beneath ; anal tuft 

 greyish-ochreous. Legs : anterior pair fuscous, narrowly paler beneath, with pale 

 rings at all the joints ; posterior pair pale oehreous, dusted externally with fuscous 

 except at the joints, the tarsi alone showing dark bars internally between the joints. 



From Major Hering's statement (S. E. Z., I. c.) that the ground-colour is " as 

 a rule a bright roe-brown, rarely a mouse-grey," and from the four examples that he 

 kindly sent me, I conclude that in Tliuringia the insect is, on the whole, browner 

 and brighter than in England, whei-e the typical " bright roe-brown " form is not 

 among those that occur most frequently. 



This species, thougti extremely variable in both sexes, may gene- 

 rally be recognised by its delicately, though broadly, marbled appear- 

 ance, due to the ground-colour being broken up by the pale fascia and 

 the clusters of pale scales, and always by the large size and peculiar 

 character of the spots, of which the most conspicuous are the second 

 on the fold and the two on the disc. In its allies the typical spots are 

 like spots or dots of black ink, in salicornics they resemble blots of 

 some coloured ink. There is no dark longitudinal streak, nor any pale 

 inner-marginal viita. From marmorella, which it will follow in our 

 lists, it is readily distinguished by its larger size, its less strongly- 

 contrasted colours, and by the absence of any paler vitta. 



Larva of Lita salicornIjE, Brg. 

 For the following description of the larva and its habits I am 

 greatly indebted to Mr. W. H. B. Fletcher : — 



" Length about 5 lines. Head varying from pale brown to nearly black : plate 

 on second segment, and anal flap which is concolorous with the head, similarly 

 variable in colour. Legs black. Grround-colour of body dull yellowish-green; 

 dorsal line red ; sub-dorsal region broadly red, with patches of the ground-colour 

 round the usual tubercles ; claspers same as ground-colour. The rod markings vary 

 greatly in intensity, often being nearly obsolete."
