30 THE MOTHS OF THE BRITISH ISLES. 



the inner margin is tinged with reddish orange at the base, or 

 along the basal half, and there are some clouds of the same 

 colour on the black submarginal line. This is conformis of 

 British authors. 



The caterpillar (drawn from a skin, Plate 8, Fig. i) is olive 

 brown, tinged with green above, and paler brown, tinged with 

 pink beneath ; the dots are yellowish in black circles, and there 

 is a dark olive-brown mark on ring i ; there are three yellow 

 lines along the back, the central one interrupted by darker 

 brown freckles, clustered so as to form a series of diamond- 

 shaped patches, and the others are edged above with dark olive. 

 It feeds on alder, from April to June. 



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

 hibernation, in March and April. Ivy bloom and sugar attract 

 it in the autumn, and it has been taken at sallow catkins as well 

 as at sugar in the spring. 



Since i86i,when its occurrence in Wales was first announced, 

 it has been found more or less regularly in Glamorganshire, 

 South Wales, or the adjoining English county of Monmouth. 

 The latest record is that by Mr. P. J. Barraud, who took a male 

 specimen at sallow bloom in the Wye Valley on March 31, 

 1907. The capture of a specimen at sugar, near Brighton, 

 September 13, 1898, has been reported. One specimen has 

 been recorded from Yorks., another from Westmoreland ; and 

 in 1902, two from near Lancaster. Wales, however, appears 

 to be the home of this species in the British Isles.

The example of this species shown on Plate 13, Fig. 3, is of 

 the typical form, and hails from the Continent. Of the six 

 specimens observed in England the majority have been recorded 

 as zinckenii^ Treitschke, a form having the fore wings more 

 variegated with white. Another form, ab. somniculosa^ Hering,
