ADSC1TA. 99 



by the antennas, which terminate in a blunt club. In the male 

 the serrations become less marked towards the club, and the 

 antennae are not dentated in the female. 



Varieties are sometimes met with in which the fore-wings 

 are blue, whilst sometimes the abdomen is reddish-golden. 

 The expanse of the wings varies from an inch to an inch and 

 a quarter. The larva is ashy-grey, with a dorsal row of trian- 

 gular black marks, and a whitish lateral stripe above a broader 

 reddish one; the head and fore-legs are black. It feeds on sorrel. 



This Moth, though always local, is still common in meadows 

 in many parts of England ; it has also been taken at Oban 

 and elsewhere in Scotland.

Fore-wings shining green ; hind-wings smoky black, semi- 

 transparent. The head and body are golden green. The 

 antennae are slightly thickened towards the tip, being serrated 

 in the male, but simple in the female. The expanse of the 

 wings is about an inch. 



The larva, which has a black head and legs, is brown, with 

 a dingy white median dorsal stripe narrowly bordered with 

 reddish-purple. It feeds on the common sun-cistus (Helianthe- 

 Hium vulgare\ but will also eat sorrel in captivity. 



This species is of a more bluish-green than A. statices, and 

 the sexes do not differ in size, whereas in A. statices the males 

 are much larger than the females. It is a hill-side rather than 

 a meadow insect, and has been found in various parts of Eng- 

 land, but was for many years confounded with A. statices.
