236 LEPIDOPTERA. 



July and August in the seed pods Aitrarialus glijcypliillos, 

 at first gnawing the inside of the pod, afterwards eating the 

 seeds. Mr. Warren says that after clearing out the seed 

 pod it moves on to another, its presence being betrayed hy 

 a slight discoloration near the base. When full-fed entering 

 the earth for pupation. 



The moth flies in the afternoon sunshine, from two o'clock 

 onward ; the male with great swiftness, so as to be nearly 

 invisible on the wing, the females more gently, about its 

 food-plant, the milk vetch. It was discovered as an inhabit- 

 ant of this county in the year 1887 by Mr. W. Warren, among 

 specimens captured by Mr. Wm. Thompson, of Stony 

 Stratford, Bucks. Since then it has been found in Sussex by 

 Mr. W. H. B. Fletcher ; in Surrey by Mr. H. J. Turner ; in 

 Herefoi'dshire by Mr. Hutchinson ; and in Cambs by Mr. 

 Warren, but it is still one of our most local species , though 

 not rare in these restricted localities — the onl}^ ones of which 

 I am aware in these Islands. Abroad it is found in Germany, 

 Lower Austria, Hungary, Livonia, and in Asia Minor.
