the Charlonia group of the genus Anthocharis. 525 



densely irrorated with light grey ; they are decidedly paler than 

 in Charlonia, and much less spotted than in that species. Mesopo- 

 tamica is also a larger insect than Donzel's species, measuring 

 from 36 to 44 mm. 



This variety is as yet only recorded from Armenia ; 

 my specimens were all taken at Malatia. 



Lucilla, Biitl. 

 J . Fore wings pale gamboge-yellow, the blackish-brown dis- 

 coidal spot large, with the dark apical patch extending more than 

 three-quarters down the posterior margin, and angled interiorly in 

 the same manner as Pcnia, the spotted transverse band herein 

 being more or less distinctly marked. Costa and fringes pink. 

 Hind wings same colour as fore wings, the base of all being 

 blackish. Beneath the fore wings are decidedly paler yellow, and 

 the discoidal spot is smaller than above, with the apical patch 

 showing through as a dark dusting, of the same shape as on the 

 upper surface. The hind wings are also paler yellow, with only a 

 very slight dusting indeed of dark scales on the posterior margin ; 

 the central white spot and spotted margin as in Charlonia. This 

 description is taken from Butler's type, but from the series now in 

 the National Collection, numbering in all fourteen ^ $ and J $ , it 

 may be well to add somewhat respecting the under surface to it ; the 

 apical patch is sometimes more darkly dusted than the type, and 

 also the hind wings occasionally approach near to the hue of 

 Charlonia in being finely irrorated with grey, giving them the 

 colour of yellowish grey, instead of the very decided yellow of the 

 type. 



5 . The fore wings of ? are very pale whitish sulphur, with the 

 blackish discoidal spot very large indeed, extending right down to 

 the inner margin of the cell, being broad in proportion, and of 

 a roughly quadrangular shape ; the blackish apical patch is also 

 very large, angled as in <? , and extending broadly even lower down 

 the posterior margin than in that sex, with only just a trace of the 

 transverse spotted band. Hind wings yellow, with the least trace 

 of a greenish tinge, and with a broad border of dark dusting all 

 round the posterior margin. Beneath the $ differs in no way 

 whatever from the <? , even the discoidal spot being no larger, 

 though so large on the upper surface. 



The females in the National Collection are very 

 interesting, as they vary much in coloration, one being 

 almost quite white, whereas the extreme in the opposite 

 direction is very yellow.
