372 On the occurrence of Colias Edusa, by James Hardy. 



again very wild, resting only for a short interval among the 

 grass ; and it did not appear to be attracted to any flower. After a 

 few shif tings it careered away seaward over the black tidal covered 

 rocks. On the 12th of June, being at Dowlaw dean, near Fast- 

 castle, C. Eiusa was observed frequenting the blossom of the 

 Bird's-foot Trefoil {Lotus corniculatus), the principal papilionaceous 

 plant on that coast. Twice I nearly caught one ; but it managed 

 t3 evade my efforts in that respect ; and after experiencing a few 

 rash attempts to arrest its free movements, it decamped. It was 

 again visible on the sea-banks at Oldcambus on June 16th; and 

 in an inland dean there, and on an old grass field on the 19th. 

 These were beautiful fresh examples. July 4th terminated its 

 visits, and then it was seated on a footpath. The wings had 

 become much shattered. I never saw more than one in each 

 instance. 



Mr Ferguson of Dunse, writes, "I noticed C. Edusa on only 

 two occasions. The first was on the 9th June, 1877, on the road 

 between Grant's House and Cockburnspath, directly opposite 

 Penmanshiel Woods ; and the second about a month later near 

 Fogo-rig- On both occasions a solitary individual was all I met 

 with. The first was a male insect, very nimble and strong on 

 the wing, and defied all my efforts to capture it ; the other was 

 a female, spent and ragged to the last degree. Both specimens, 

 so far as I could judge, were of the normal size and colouring." 



Mr George Bolam, about the time of its earliest occurence, 

 captured one in a garden at Berwick ; and Mr A. H. Evans 

 observed one of these butterflies at Scremerston. Dr Stuart and 

 Mr John Anderson have also seen it in their respective localities. 

 Dr Stuart, on the 5th June, noted two specimens on the road 

 across Sunwick Moor, near Fishwick. Thereafter he saw many 

 Clouded Yellows, till the end of the month, but captured one 

 specimen only. " They flew like birds and were exceedingly wild 

 — lighting particularly on the flowers of dandelions. They were 

 new to me ; but were seen by many persons all over the country." 

 Mr W. B. Boyd on one occasion during the summer, saw it 

 passing in its usual headlong course across his garden at Ormiston 

 House ; and when the Club visited Lilliesleaf, Mr Turnbull had 

 a fresh specimen to show, that had been caught there. 



Mr Kelly communicates that about the middle of June, several 

 examples of C. Edusa were flying about in Lauderdale, but few
