882 NOTE ON THE OCCUBRENCE OF THE 



The Tortrices and Tinea, were not plentiful last season, the 

 larvae having probably perished by the long drought of the pre- 

 vious summer. 



The best of my captures were — A. cniccma and P. jyyislongana. 



At Sweethope in September I took Cidaria j^sittacata (local), 

 miata, and testata; also larvae of Notodonta camelina and dro- 

 medarius on birch and alder ; a few Dictma on poplar, and one 

 DictcBoides on birch. The larvae of Bovihyx ruhi were numerous 

 on the heather. 



Many species of butterflies (Diurni) were scarce with us last 

 season, although the common whites, Pieris, BrassiccE, and 

 Napi, were as numerous as usual, but not so in the South of 

 England. 



The Common Blue, Meadow Brown, Nettle Tortoise Shell, 

 and Red Admiral, showed themselves in average numbers. 



Of Vanessa Cardui (Painted Lady) I only saw one specimen 

 on the wing. The larvae were very numerous on the thistles at 

 Marsden the year previous. 



V. lo (Peacock) seems to have left the neighbourhood alto- 

 gether, I have not seen a single specimen on the wing here for 

 four or five years. — W. Maling, St. Mary's Terrace, Newcastle,

XXIV. — Note on the Occurrence of the Trunk of an Oak in the 

 Boulder Clay. By Sir Walter C. Trevelyan, Bart. 



On the 24th of June, 1869, when walking along the line of the 

 Northumberland Central Railway, I observed in a cutting through 

 the " Boulder Clay," between the Lindenshaw and Cocker Burns 

 (at an elevation of about 450 feet above the sea), part of the 

 stem of an ancient oak tree, standing in a vertical position, and 

 looking very like the stump of a tree which might have been 

 growing on the spot, but it appeared to be at too great a depth 

 in the clay (the top of it being 3*50 feet below the surface) for 

 that to have been the case.
