well-rounded (very unlike those of suffumata)^ serve to separate 

 it at a glance. The hind wings are devoid of markings, shining 

 whitish-grey. Seen in a series the general appearance is most 

 striking, and somewhat suggests a cross between suffiimata and 

 silaceataP 



^- 335- Zygaena Achilleae— Further records. — Mr. Percy 

 C. Reid, in a note to the Entomologist for 1919, p. 188, writes 

 in the course of his account of a hunt for this species, 

 " Eventually we fixed on a spot some twenty miles from 

 Oban, which we thought might prove likely, and there we 

 arrived on the afternoon of June 26. Though unsuccessful 

 at first we were not prepared to own ourselves beaten, and it 

 was not long before we were oat again in a fresh direction, 



when suddenly E spotted a pair of 'Burnets' in cop., 



which needed only a cursory examination to cause both of us to 

 exclaim, ' Achilleae ! ' Guided by this find, we soon came across 

 others, and eventually found that the insect occurred nearly 

 everywhere in suitable spots and was certainly the common 

 'Burnet' of this district. We found it to frequent dry and 

 sheltered banks covered with an abundance of mixed vegeta- 

 tion — heath, birds-foot trefoil, wild thyme, vetch, Pote7itilla, 

 etc., and I am inclined to think its chief food-plant is probably 

 Lotus corniculatics. It occurred at all elevations up to 300 

 feet, and I have no doubt higher." 



Mr. Esson, in the same number (675), p. 189, states that he 

 met with this species after a tramp of over twenty miles in a 

 locality ten miles from the place where Renton found it some 

 ten years earlier.
