area of all the wings is white. Specimens with part of a wing, 

 or with the hind wings having this bleached appearance, due 

 to failure of pigment, are not very unusual. But a perfectly 

 symmetrical and complete arrangement of this aberrational 

 colouring is rare. 



The promise held out in June of " Clouded Yellow " 

 was not fulfilled. In that month I saw several, doubtless 

 immigrants, which led me to anticipate a great display in 

 August, in which month I took one female on the 21st and 

 left others at liberty. But the terrific gale on the night of the 

 27th, followed by a deluge of rain, destroyed all hopes, aud 

 Colias ednsa was exterminated in all stages of larva, pupa and 

 imago. The Small Tortoiseshell, which had been delightfully 

 plentiful, especially among fields of lucerne, was also " knocked 

 out " by the same gale. 



After these general remarks on the season, I pass to the 

 notice of the capture of insects not previously recorded for 

 Guernsey. I am glad to be able to add six to our list which, 

 if they include no rare or showy individuals, afford the more 

 conclusive evidence that there is still interesting work for a 

 patriotic field-naturalist before our knowledge of the Guernsey 

 Lepidoptera can be regarded as approximately complete. 



The new claimants to the honour of being enrolled as 

 " proper Guernsey " are : — 



Acidalia SUbserieiata. One recorded by Mr. Luff in Sark, 1870, and 

 several in Alderney, 1873, but not hitherto in Guernsey. It is not very 

 uncommon in June, especially in hedges below Le Coudre, St. Peter's. 



The remaining five novelties belong to the families of the 

 Micro-Lepidoptera, and are : — 



Rhodophsea advenella. From Fosse Landry, 2nd August, 1917. 



Salebria fusea. At Bon Eepos, 5th July, 1917. 



Hom030SOma bincevella, Hb. On thistle at Pleinmont Point, 10th July, 

 1917. 



CePOStoma xylostella, L. (Larpella, Setoff.) At Fontenelle, Forest, 20th 

 July, 1917. 



Aealla (Peronea) SChalleriana. Same place and time ; also at the Gouffre. 



Some other captures I made this year may be mentioned 

 as having interest, since they are things which have only been 

 taken once before. Erastria jascicma, first record last year. 

 JEllopia prosapiaria, one flew to light on June 12th, in my 

 vicarage. Both Mr. Luff and myself put it down as some 

 accidental introduction and not a genuine native. This sum- 

 mer, however, a very fine female settled on the grass close to 

 where I was sitting at the end of the Pezerie, July 13th, 

 which I think should lead me to the discovery of its habitat
