 lenticular or angular spaces between the laminae of cellulose. The same is 

 seen two-thirds down h.

XVI. Notes of an Entomological Excursion to the Neiv Forest, 

 Hampshire, in July 1880. By William Evans, Esq. 



(Read 21st December 188L) 



Abstract. 



In this paper the author gave an account of a three 

 weeks' excursion to the New Forest undertaken by him in 

 July 1880. A small hamlet called Bank was chosen for 

 headquarters, and in its immediate neighbourhood, as well 

 as in those parts of the forest stretching out to Lyndhurst 

 on the one hand and Brockenhurst on the other, the bulk of 

 the collecting was done. 



Having indicated the position of the forest, and referred to 

 its antiquity and historical associations, the author proceeded
