margins broadly dark-brown by the varietal name of Lyllus, 

 Esp. This is evidently an error ; specimens with dark 

 margins are typical Paiiiphllns, and all the gradations of 

 darker and paler are so completely filled that no varietal 

 name seems necessary, nor indeed can be defined. The 

 variety called Lyllua belongs to the southern area of the 

 distribution of the species, and is described by Lang as 

 "generally somewhat larger than the type and brighter 

 in colour, the hind margins have a narrow black line on 

 all the wings ; the fore wings have the apical spot more 

 distinct than the type. Underside of fore wings light orange, 

 with a central reddish streak descending from the costa about 

 two-thirds across the wing ; apical black spot well defined ; 

 hind margin and apex yellowish grey. Specimens often 

 have an ante-marginal leaden line. Hind wings yellowish 

 grey, the basal portion darker than the rest ; there is a 

 central lighter streak, and sometimes a few sub-marginal 

 light dots." This description would answer fairly well for 

 some of our paler specimens, but his figure represents the 

 underside of the hind wings as very different from any seen 

 in this country. 



On the wing throughout the summer from the end of 

 May till September, and certainly double-brooded, though 

 not completely so. Apparently there is a succession of 

 emergences from earlier and later larvaj, and, from the 

 earlier, a second generation in August. Probably in its more 

 northern and western range there is but one brood ; it has 

 been distinctly asserted that this is so in the south of 

 Ireland, the only emergence taking j^lace in June and July. 



Larva about five-sixths of an inch long ; head rounded ; 

 body more tapering backwards than in front ; anal segment 

 with two short points ; colour clear green, with darker green 

 dorsal stripe and a spiracular stripe not so dark ; anal points 

 pink (Hellins). Mr. E. Newman's description is more full, 

 — the colour of the head opaque green, mouth and ocelli
