with, the discii] spot beinj; a great broad dash reaching nearly to the 

 base of the wing, with a broad black patch on the costa opposite it, 

 much blackening of the wing beyond the discal spot, and a distinct 

 black line on the fringe, where it occurs in marqinata and marginuJa, 

 a line however of black (not purple) scales. This line was also 

 present in the specimen of the 2(Jth. The only two specimens of the 

 Jij/erana form in which 1 have met with it. These specimens were no 

 doubt nearly two months in the pupa state owing to the colder 

 weather, and to this more than anything else their extreme darkness 

 may be due. Altogether 15 specimens emerged in November, De- 

 cember, and January, and of these 13 (10 Jii/erana and 3 viarginata) 

 were darker than any specimens among the whole 400 odd emerging 

 up to end of October. One ? made a slight approach to being ab. 

 alpha, as well as being very dark. There is one other remarkable 

 specimen amongst the hijerana section, this is a (J specimen with ricb 

 orange tinting of no less than 26 mm. in expanse, the next largest I 

 have (except one of 24 mm.) being under 23 mm., and the average 

 less than 22 mm. ; 26 mm. is about the expanse of the largest ? 

 specimen, the average being well under 25 mm. 



Turning to the marqinata section. There is a remarkable differ- 

 ence between the hill and shore sections. I have classified 23 speci- 

 mens from La Plage as marqinata and 5 others as marginula, but in 

 the Les Maures series 128 as marginata and 1 only as marginula. 

 There is a much larger proportion of golden-orange forms amongst 

 the marginata than was the case two years ago, but less perhaps than 

 amongst those bred from eggs laid by them. There are all gradations 

 between the orange and purple specimens, so that a strictly accurate 

 census is impossible,- but drawing the line as well as I can I should 

 tabulate the marginata as under : —

The discal spot is usually invisible in marginata, but it can be 

 made out in some of the most orange specimens, and two of these are 

 distinctly Milliere's var. alpha so far as the spot is concerned.
