220 LEPIDOPTERA. 



common, but no such attractive visitant now haunts our 

 London gardens. Its headquarters in this country are in 

 Cambridgeshire, where at times its larva is really mischievous ; 

 and it is also frequent throughout the Eastern counties ; less 

 so in the south, and apparently very rare in Sussex and 

 Dorset ; more frequent in Surrey, also in Hertfordshire, 

 Huntingdonshire and Northamptonshire ; scarce in Oxford- 

 shire and Berks, also at Weston-super-Mare, Somerset, and 

 in Herefordshire. Further north I find no records, and there 

 appears to be no certainty that it has ever occurred in 

 Ireland. Abroad its range is more southern — Central and 

 Southern Europe, South Sweden, Syria, and through the 

 north of Asia Minor. At Gibraltar Mr. J. J. Walker found 

 it on the wing in April.
