history of this butterfly in all its stages has been sketched from the life by the Rev. J. F. Dawson (who has made an intimate acquaintance with a colony of the insect at Sandown, Isle of Wight), and will be found in the Zoologist, p. 1271.
The butterfly first appears about the first or second week in May, and thence continues till about the middle of June, seldom enduring till July. It is to be looked for in rough, broken ground, such as the Isle of Wight landslips, where plenty of the narrow-leaved plantain grows.
Other localities for the Glanville Fritillary are, Folkestone below West-Cliff (abundant); round Dover; Birchwood; Dartford, Kent; Stapleford, near Cambridge; Yorkshire; Lincolnshire; Wiltshire; Peterboro', Stowmarket; and in Scotland, at Falkland in Fifeshire.
THE PEARL-BORDERED LIKENESS FRITILLARY. (Melitæa Athalia.)
([Plate XI]. fig. 3.)
This is another very local butterfly, though rather more widely and generally distributed than the last, which, as before stated, it greatly resembles in appearance, especially on the upper side.
It may be characterised negatively as not having the rows of black spots found on both surfaces of Cinxia, though its colouring is very similar—fulvous (or orange-brown) and black above; straw-coloured, fulvous, and black beneath.
The caterpillar is black, with rust-coloured spines; and feeds on various species of plantain.
