342 THE MOTHS OF THE BRITISH ISLES. 



Scarce Forester {Ino {Rhagades) globularice). 



Of the three species occurring in Britain this is slightly the 

 larger, at least in the male. The fore wings are green, some- 

 times with a slightly golden sheen ; fringes, greyish. The male 

 is best distinguished from statices by its more slender body, and 

 by the pectinated and rather pointed antennae. The female is 

 a good deal smaller than the male; the antennae are simple, 

 and somewhat thread-like, compared with those of the females 

 of statices and geryon. (Plate 147, Figs. 6^,75.) 



The caterpillar is green, with the raised spots inclining to 

 bluish ; two yellowish -white lines along the back, and a dark green 

 stripe along the sides ; head and plate on first ring of the bodj', 

 black. It lives on knapweeds {Centaurea 7iigra and C. scabiosd)^ 

 feeding on the leaves much in the same manner as the cater- 

 pillar of the next two species. 



The moth is out in June and July; it is partial to blossoms of 

 salad burnet {Poterium saiigitisorbd),, and only flies in the sun- 

 shine. The late Mr. J. Jenner Weir, who found the species 

 commonly on the downs near Lewes, Sussex, was the first 

 entomologist to record it as British. The best known localities 

 in Sussex are HoUingbury Vale and Cliffe Hill, but it also 

 occurs at the Devil's Dyke ne.ir Brighton. In Kent it is found 

 on the downs behind Folkestone and Shorncliffe Camp. 



The Forester [^Ino {Adscitd) statices). 



In its most frequent form in Britain, this species is bronzy 

 green (ab. ruiridis^ Tutt) ; the typical bluish green type is much 

 less frequent. The female is smaller than the male, but the 

 difference in size is hardly ever so marked as in the sexes of 

 globnlarice. The antenn^E of the male are pectinated, but the 

 tips are thickened. (Plate 147, Figs. 8 J , 9 ? .)
