ISLE OF WIGHT WAVE. 11$ 



The present species, to which Haworth gave the English 

 name here used, is whitish straw-coloured, and silky in appear- 

 ance ; the wings have a central black dot and four or five dusky 

 cross lines, some of which are more distinct than others ; the 

 front edge of the fore wings is tinged with reddish brown, in 

 which is often a dark dot at the ends of the first and central 

 lines ; a series of linear blackish dots at the base of the fringes, 

 most distinct on the fore wings. 



The somewhat stumpy caterpillar is dull smoky brown, 

 marbled and variegated with ochreous, the darker colour most 

 in evidence in front, and the ochreous behind ; an ochreous 

 line along the middle of the back, and one along the region of 

 the spiracles ; white spots on rings 5-7. (Adapted from Porritt.) 

 It feeds from August to April on dandelion and other low- 

 growing plants, and especially on the withered leaves. The 

 moth occurs among weeds growing on banks, and hedgerows, 

 and the outskirts of woods, in greater or lesser plenty through- 

 out the South of England ; but it becomes local, and more or 

 less rare in the north of the country. In Scotland it is said to 

 be uncommon in Clydesdale, but has not been noted from 

 Ireland, or from Wales.

This species (Plate 45, Fig. 16) is the osseaia of Fabricius, 

 but not of Haworth and other British authors. It is very 

 similar in general appearance to the species last considered, 

 but the wings are somewhat less ample, and rather yellowei 

 in tint. It is most readily recognised, however, by the 

 distinctly reddish stripe on the front edge of the fore wings. 

 Previous to 1891, when specimens were obtained by Mr. A. J. 

 Hodges in the Isle of Wight, the species was not certainly 

 known to be an inhabitant of the British Isles, although it 

 seems to have been represented in many collections. The
