Report of the Byfleet Field Meeting, June ist, 1901. 

 By W. J. Lucas. Read July nth. 



Ai'.ouT twenty-five members and friends assembled for the field 

 meeting at the Byfleet Canal on Saturday, June ist, but, except in 

 the case of those few who came down in the morning, they could 

 scarcely form a just estimate of the resources of the district as a 

 collecting ground, owing to the rain which commenced to fall 

 almost as soon as the afternoon train arrived. Those who had 

 come down earlier in most cases proceeded to Woking, and worked 

 their way back to Byfleet. These experienced the fine weather of 

 the morning, and were able to gauge the capabilities of the district 

 from the point of view of a naturalist. Mr. Knock expressed this in 

 his usual vivid style when he told me that " Step would not go more 

 than one at a time, as shells were fine and large." Insects, of 

 course, dragonflies especially, were as plentiful as the shells. 



Notwithstanding the rain some collecting was done, the results 

 being as follow : 



Flowers most worthy of note were the buckbean {Me/iyanthes 

 trifoliata) and Sedum telephiuvi. Mr. Enock could not find the 

 beautiful orchid Epipactis palustris, which used to occur near 

 " Bunker's " Bridge. 



Birds' Nests reported by Mr. F. M. B. Carr were a wood 

 warbler's, with two eggs, and a robin's, also with eggs. 



Mr. R. A. Adkin gives a list of fourteen Mollusca, all but one 

 aquatic : — Arion ater, Planorbis atbiis, P. vortex, P. complanatiis, P. 

 contortns, Linwcea peregra, L. auricuhiria, L. stagnah's, Paludimi 

 vivipara, Bythinia tentaciilata, Unio pictorum, Sphcereum cor/ieum, 

 S. riviro/a, and Pisidiian amnicum. 



Turning now to the insects, no Orthoptera were reported, but 

 the NBuroptera (Linnaeus) were well represented. Of the 

 Psocidia none were captured, and there was but one of the Perlidia, 

 viz. Neinoura variegata. Of the Ephemeridia, Ephemera vulgata 

 was common, and the little Centroptilum pemiulatum was also 

 secured. Of the Odonata were taken Brachytron pratense commonly, 

 Libellula depressa, Cordulia cenea, Calopteryx spkndens, Efythromnia 

 naias (Carr), Pyrrhosoma nyniphula, P. tenelluvi (Kemp), Ischnura 

 elegans, accompanied by the $ var. with orange thorax, Agrion 

 puethi, Agrion pulchellum, of which Mr. Turner gave me a nice 

 female, and Enallagina cyathigerum. The Planipennia were repre- 

 sented by Sialis tiitaria, of which Mr. Step saw one ovipositing, and 

 whose eggs I made use of as a copy from which to obtain a coloured 

 figure, Osmylus macuhitus (Kemp), Hemerobms humuli, Paiiorpa 

 communis, and P. gernianica. Trichoptera were Phryganea grandis,
