Mr. Bishop read a paper entitled " The Natural History of 

 the Guildford District." 



APRIL 11th, 1901. 



Mr. H. S. Kremlin, F.E.S., President, in the Chair. 



Mr, Carpenter exhibited a large number of specimens of 

 Pieris napi, reared from ova deposited in May, i8g6. The 

 larvae fed up and pupated in June, i8g6. About half of these 

 emerged during the latter part of June and the early part of 

 July of the same year. The remainder of the brood went 

 over the winter of 1896-7, and emerged in April and May 

 of the latter year. The early emergences were all very 

 typical, with scarcely any variation, while the latter were 

 especially noticeable for the great amount of variation in the 

 black markings of the female. He also exhibited a large 

 number of bred specimens of Mclitcea aurinia from Penarth 

 and Carlisle. Mr. Montgomery noted a female of the former 

 species without the discoidal mark on the upper surface of 

 the wing. 



Mr. McArthur exhibited specimens of Plntclla anmilatcUa 

 from the Orkneys. They were very bright and conspicu- 

 ously marked. 



The President exhibited a number of species of Lepi- 

 doptera and other insects taken during a short trip to 

 Canada last year, and read notes on their occurrence. 



Mr. W. J. Lucas exhibited ten species of dragonflies 

 collected by Mr. H. S. Fremlin in Canada in igoo. All 

 the specimens but one were taken at Loon Creek, Fort 

 qu'Appelle, Assiniboia. The most noticeable point is the 

 general resemblance to British species. There are three 

 Sympctra, one closely resembling our 5. sanguineuin and 

 another our S.flavcohim. The specimens of L. qiiadriniaculata 

 are unsuffused and with small nodal spots, like the northern 

 British forms. The Goniphus came on board ship near 

 Montreal, and insisted on being captured. The only 

 Mschna IS a British s\)ec\es, AL. jnncea. The Lcstcs is very 

 near L. sponsa, if not identical with that common British 

 species. Then we have at least three Agrionines, of whose 

 identity I have no idea at present. 



Mr. Knock reported that Mr. J. Knock and himself had 

 met with an example of the spider Epeira nmhratica, which 

 had hybernated in an old trunk at Golder's Hill. He also
