fS PLATE CLXV. 



The caterpillar of this fpecies is found on the White Thorn, in 

 April ; in May it becomes a pupa : the moth does not appear before 

 September. 



It will be readily conje6lure(i, from its Englifli name^ to be more 

 frequently taken about Ealing^ in Middle/ex, than elfewhere, though 

 it is not peculiar, like fome infe£ls, to one place only. The cater- 

 pillar is fmooth, or without any hairs ; it eats ravenoufly, is very 

 fluggifh, and forms a fine filky web, in the ground, in which it palTes 

 to the pupa ftate *. We find the moth very liable to variation in 

 colours ; in fome fpecimens the green is very brilliant, in others the 

 red ; and again, in others, the lunar white marks are very con- 

 fpicuous. In fome fpecimens, natives of warm countries, we have 

 feen them finer coloured than thofe from the northern parts of 

 Europe. ^
