The _caterpillar_, which feeds on the narrow-leaved plantain, is thorny and black, with reddish head and legs. The chrysalis is brownish, marked with fulvous tint. A highly interesting account of the habits and {136} 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. {137} 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. The _butterfly_ is out from May to July, and is met with (if at all) on heaths, clearings in woods, &c. Localities, in some of which it is very plentiful, are, Caen Wood; Coombe Wood; Epping; Halton, Bucks; Bedford; Aspley Wood, Beds; Plymouth, Teignmouth, Stowmarket, Dartmoor, Devonshire; Oxford; Wiltshire; Colchester; St. Osyth; Tenterden; Faversham; Deal; Canterbury. Very rare in north of England. * * * * * THE GREASY OR MARSH FRITILLARY. (_Melitæa Artemis._) (Plate XI. fig. 4.)
