30 MARBLED WHITE. 



It is with us very locally, though widely distributed ; in Scotland, 

 however, it is not known. 



I have taken this insect in plenty at Pinhay ClifF, Devonshire ; near 

 Lyme Regis and Lulworth Cove, Dorsetshire ; also at Marr, near 

 Doncaster, and on Buttercrambe moor, near Stamford-Bridge, Yorkshire, 

 in which county it has also been taken at Werst Hill, near Pontefract. 

 It is found in abundance in Hartley Wood, near St. Osyth, Essex, 

 and occurs also at Manningtree, in the same county ; and near Great 

 Bedwyn and Sarum, Wiltshire, in isolated spots near woods, as J. W. 

 Lukis, Esq., informs me ; Preston, in Lancashire ; Sywell Wood, near 

 Northampton, and in jilenty in the wood of Ashton Wold, near Pole- 

 brook, in the same county, where I have taken it, in company with 

 the Rev. William Bree. Li Lincolnshire, in a lane between West 

 Rasen and Kingerby Wood. In Hampshire, Winchester and Lyndhurst, 

 and in the Isle of Wight; in Gloucestershire, near Dursley; in Sussex, 

 near Brighton; and in Essex, in Hainault Forest. It is plentiful near 

 Clonmel, in Ireland. 



The perfect insect appears in June and July. 



The caterpillar feeds on the cat's-tail grass. 



The Marble White varies in the expanse of its wings from two 

 inches to nearly two and a quarter. Its colours are a fine yellowish 

 white and black, with which the whole surface of the wings is chequered 

 over, so that one can hardly say whether the white or the black is 

 the ground-colour. There is a large whitish oval spot near the base 

 of each wing, succeeded by four long whitish patches, the two middle 

 ones being nearest to the outside of the wings, and smaller than the 

 others. Between these and the tip are two smaller white spots, and 

 there is a row of white spots near the margin, divided by a black 

 line, which is again succeeded by the white, forming a margin, inter- 

 rupted by the continuation of the black which had formed the sides 

 of the white spots before their intersection by the black line. The 

 hind wings have a large oval whitish spot near the base, then an 

 irregular black mark, succeeded by a very broad bar of the former 

 colour, then black again, and then a row of white crescents, varying 

 in size, near the outside margin, divided by a black line, as in the 

 fore wings. 



Underneath, the markings correspond, but the black colour is much 

 more faint and indistinct. The fore wings have a small black eye, 

 with a white centre, near the tip. The hind wings have five eyes just 

 above the white crescents near the margins, the third from the outer 

 corner not having an eye, and the eye near the inner corner being a 

 double one. The black markings are irrorated with buff.
