THE PINK-BARRED SALLOW. 1 9 



three whitish lines along the back ; a pale stripe along the 

 sides. Head, pale brown, shining. May be found from April 

 to June on beech, or on maple where this occurs around beech 

 woods. At first it feeds on the buds, but later on the leaves ; 

 for protection during the day it spins together two of the leaves, 

 and so forms a suitable resting place. Sycamore, it may be 

 mentioned, is acceptable to this caterpillar when reared in 

 captivity. 



The moth is out in September and early October, and is 

 chiefly found in the neighbourhood of beech woods, especially 

 those in chalky districts in Oxford and adjoining counties, 

 Hertfordshire, Middlesex, Essex, Suffolk, Norfolk, Kent, Surrey, 

 Sussex, Wilts, Somerset, Dorset, and Devon. It also occurs 

 in the counties of Hereford, Worcester, and Cheshire ; it has 

 been found in Yorkshire since 1890 in several localities, 

 including Barnsley, Doncaster, Huddersfield, and Rotherham. 

 At least one specimen has been recorded from Pembrokeshire, 

 and others from Flint and Denbighshire, in Wales.

\'\/^ In some examples of this species (Plate 10, Figs. 4, 5) the 

 oblique band of the fore wings is purplish, and in others red 

 or reddish ; the former are typical, and the latter are referable 

 to ab. och?-eago, Borkhausen. Often the band is incomplete, 

 and sometimes it is only indicated by three more or less regular 

 series of reddish dots (ab. togata, Esper). I have one example 

 of this form from the Isle of Hoy, and another specimen from 

 the same locality is somewhat similar, but the spots are not so 

 well separated, and are purplish in colour. 



The eggs (Plate 6, Fig. 3) are yellowish when laid, but 

 become purplish later, and the ribs then appear whitish. 



The caterpillar when young lives on catkins of the sallow, 

 and when these fall it feeds on low-growing plants, but it will
