120 DARK GREEN FRITILLARY. 



dark marks near the outside edge are much paler; the tips 

 of the wings are paler than the rest, as are the front edges, and 

 there are a few minute faint silver dots near the corner, and 

 one very obscure one inside them. The hind wings dull green 

 over all their inner and larger portion, excepting towards the 

 upper part of the outer side, where the dull fulvous, which 

 succeeds the green in a wide band, runs into it. The border 

 is pale greenish yellow; inside this is a row of seven angular- 

 shaped spots, edged on their inner side, crescent-wise, with dull 

 green. These are followed by an irregular row of seven silver 

 spots on the outside edge of the green colour of different sizes and 

 shapes, the centre one very small, and these by about seven 

 other spots and dots of silver, also of different sizes and shapes, 

 over the base of the green. 



The female expands to the width of two inches and three- 

 quarters, or a little over; the ground colour is more dull; the 

 base much more extensively and more deeply darker coloured; 

 the dark billets are larger, and those that are open in the male 

 are filled up with black.. The hind wings are also much darker 

 at the base. 



Underneath, most of the marks are larger than in the male. 



The caterpillar is of a blackish colour, with a whitish line 

 down the back, and another on the side, over which is a row 

 of eight small spots. 



One variety of this insect has been described as a distinct 

 species, under the name of 'Papilio Charlotta,' (Haworth,) and 

 'Argynnis Caroletta,' (Miss Jermyn.) It has ''the two costal 

 spots on both sides of the fore wings united, and only nineteen 

 instead of twenty-one silvery spots on the under side of the 

 hind wings, several of the ordinary spots at the base being 

 confluent." Dr. Abbot took three specimens of this variety, 

 nearly all alike, near Bedford; and INIr. Dale has another, taken 

 near Peterborough, which on the under side represents on one 

 wing the character of 'Caroletta,' and on the other that of 

 'Aglaia,' thereby proving it to be, "sans doute," a variety only. 



Another splendid variety, of which specimens have been taken 

 near Ipswich and Birmingham, has ''the ujjper surface of the
