BORDERED GREY. 32$ 



Bordered White {Bupalus pmiarid). 



Two forms of the male of this species are represented on 

 Plate 141. Fig. 9 shows the yellow English form (Sih.JiavescenSy 

 White), and Fig. 10 the white North English and Scotch forms. 

 In southern localities, however, specimens occur which are 

 almost as white as the northern or even Scotch examples ; I 

 have two such specimens from Surrey. There is considerable 

 variation in the size of area occupied by the pale colour, both in 

 v/hite and yellow forms. In one of the former, from Forres, in 

 Scotland, the white is represented by a small oval spot and 

 dappled streak on the fore wings ; an entirely black specimen 

 (ab. nigricarius^ Backhaus) has been noted from Berkshire. In 

 other specimens there is an unusually large proportion of pale 

 colour. The females are usually orange, or orange yellow, in 

 the south (Fig. 8) ; and yellowish brown, or dingy orange brown, 

 in the north. The brownish-coloured females occasionally occur 

 in the south, and the brighter form of this sex is sometimes 

 taken in the Midlands, where the two forms of the species seem 

 to overlap. 



The long, greenish caterpillar is marked with whitish or 

 yellow lines ; those along the back are edged with black, and 

 along the sides with dark green. It feeds from August to 

 October on the needles of the pine, and also on other firs. 

 (Plate 140, Fig. 3 ; Fig. 3a shows a photo of the chrysalis, twice 

 natural size, by Mr. H. Main.) The moth is out in May and 

 June, later in the north ; it is generally common in pine woods 

 throughout England, Wales, and Scotland. 



Bordered Grey {Selidosema erUeiaiia). 



Portraits of the male and female of this species (known also 

 as plumaria) will be found on Plate 143, Figs, i 5 > 2 $ . The 

 cross markings are more distinct in some specimens than in 

 others, and the central one of the fore wings varies in width.
