GENUS I. BUTTERFLIES. 



SEC. V. SP. XXXVIII. CLOUDED YELLOW. 

 PI. 33- 



Hayale. Linnœus. 



This is a very rare fpecies of butterfly. In all my refearches after infects I never 

 met with it but in the ifle of Sheppey, and on a hilly pafture field near Ofpring 

 in Kent. I found it in different years at both places, and it appeared to be 

 locally attached to the fpot. It is out in the winged ftate the middle of Auguft, 

 and is not difficult to take on the wing, as it does not ramble far, or fly fwift. 

 The male is lefs than the female, but in colour and markings they are nearly 

 alike. See the upper parts of the male at fig. i, and the under parts at fig. a. 



S P. XXXIX. PALE CLOUDED YELLOW. 



This fpecies is likewife very rare. I met with a brood of thefe butterflies in 

 a gravelly pafture field in Kent, and they were all of the fame pale yellow co- 

 lour : but in every other character they perfectly agreed with the above de- 

 fcribed ; and it is a doubt with me, whether this be a diftinct fpecies, or only a 

 variety in colour. This fly is likewife on the wing the middle of Auguft. Its 

 upper parts are reprefented at fig. 3, and the under fide at fig. 4.
