298 Notes on the Rarer Lepidoptera. By G. Bolam. 



Setina irrorella. Clerck. 

 The station at Eyemouth, recorded by Mr William Shaw many 

 years ago, is the only locality in which I have been able to meet 

 with this pretty moth, and it is not generally so abundant there as 

 to be found without careful looking for. 



Euchelia jacobcece. L. 



The larvae are often so abundant upon the links on our sea-coast 

 as to entirely eat up large patches of their food-plant, the common 

 Ragwort, and numbers of them seem then to perish from starvntion. 

 After these years of excess, both Jacob^se and Eagwort are sometimes 

 comparatively quite scarce during the following summer. 



Except in point of size this common moth appears to present but 

 few varieties. I have, however, seen one or two individuals in 

 which the usual crimson on all the wings was supplanted by a more 

 or less pale orange colour. 



Orgyia fascelina. L. 



Occurs on all our moorlands on both sides of the border; but I 

 was rather surprised to see a fine example of this moth, in July 

 1888, which had been found at rest upon the side of a house on 

 the Quay Walls, Berwick. 



Demas coryli. L. 

 Usually considered rather a rare moth, but in some seasons I have 

 found the larvaa in considerable numbers in the autumn ; it seems, 

 however, to be difficult to rear it to the perfect state. I have found 

 it upon beech, birch, plum, and sallow, and, amongst other localities, 

 at Fonlden Hag, Kyloe, and Newham Bog. 



Pcecilocainpa popiiH. L. 



I found a full-grown larva sunning itself on the trunk of an oak 

 tree, in Fenwick Wood, on 16th June 1895, but it had unfortunately 

 been stung by ichneumons. 



Eriogaster lanestris. L. 



Newham Bog is, so far as I am aware, the only locality where 

 this species occurs in the district ; for though Mr Selby included it 

 in his Twizell list, published in 1839, it was probably from this 

 station that he obtained it, along with Liparis salicis and some 

 others. During the last ten years I have almost annually seen the 

 conspicuous nests of the larvfc tliere, and it was no doubt some of 

 these which were seen by some of our members, when the Club 

 visited the Bog in June 1896, and which were reported, in the 

 newspaper account of the meeting, as belonging to " the Processionary 

 Moth of the continent." As a rule the larvae at Newham are found 

 upon sallows, but I have occasionally seen them on Whitethorn.
