22 THE MOTHS OF THE BRITISH ISLES. 



allies. It feeds on the seeds of wych-elm, and may be beaten 

 or jarred from the branches in April and May. The moth is 

 out in the autumn. 



The Pale-lemon Sallow {_Mellinia {Xanthia) ocellaris). 



Although sparsely marked yellowish examples of the last 

 species have been mistaken for the present one, the true 

 M. ocellaris was not known to occur in Britain until 1893, 

 when three specimens were taken at Wimbledon and Twick- 

 enham. In 1894 a specimen was recorded from Bognor in 

 Sussex, and another in West Dulwich. The following year 

 one specimen was taken at Richmond, Surrey, and one at 

 Ipswich, Suffolk. Three specimens were obtained at sugar in 

 1899, and five others in 1900, in a locality in North Kent. 

 Odd specimens have also been noted as follows : — Suffolk, 

 Beccles (1898), Woodbridge (1899) ; West Norfolk (1904 and 

 1906) ; Cambridge (1907). For further records, see Appendix. 

 The caterpillar, which is ochreous grey with black dots, feeds 

 on poplar, and is stated by one continental author to live in the 

 buds and catkins when young, and afterwards on low plants. 

 So far, it has not been detected in England. 



The moth is depicted on Plate 10, Fig. 11. From the last 

 species this one is easily separated by the more pointed fore 

 wings, by the white dot at lower end of the reniform stigma, 

 and by the different shaped cross lines. 



The moth has been taken at sugar or light in September 

 and October. 



The Opange Upper-wing (Xanthokuca (^Hoporlna) 

 croceago)» 



This species is shown in its typical form on Plate 10, Fig. 12. 

 Occasionally a dull reddish-brown form (ab. latericolor^ Ray- 

 nor) occurs, of which I some years ago reared several examples,
