Notes on the Fauna and Flora of Horsley, as observed 

 by the Members on the occasion of the Society's 

 Field Meeting on May 13th, 1893. 



Compiled by Hy. J. Turner, F.E.S. Read May i^th, 1893. 



The Members assembled at Waterloo about 2 o'clock as the 

 Committee had arranged, and after an hour's pleasant ride, mainly 

 through a fine collecting district, we arrived at our destination. 



The first capture was Eiichlo'e cardaniines, L., on the roadside near 

 the inn ; and quickly nets were swinging in all directions, for Em- 

 melesia albulata, Schiff., was crossing the road in numbers. We 

 entered the field to the right, and were soon busy with the pretty 

 but swift flying Heliaca te?iebrata, Scop, {arbuti, Fb.). Here were 

 more E. cardammes with Pieris napi, L. ; Syrichthits malvcE, L. and 

 Nasionades tages, L., somewhat worn; Polyominatus phlaas, L., 

 Lyccena icarus, Rott., and Ccenonympha pamphilus, L., freshly 

 emerged ; Euclidia 7)11, Clerck., E. glyphica, 1.., and Pyrausta pur- 

 puralis, L., in their usually damaged state; and of course the two 

 pests Crambus horiuellus, Hb., and C. pratellus, L., were well in 

 evidence. Adjoining these fields was a sliady pond, which produced, 

 among other treasures, several species of Agabus to our only 

 Coleopterist. 



Proceeding along the edge of the wood many geometers were 

 driven out ; Lomaspilis marginata, L., Cabera pusaria, L., Acidalia 

 rejjiutaria, Hb., and Asthenia candidata, Schiff., in good condition ; 

 one or two Bapta tenierata, Hb., and a single Zonoso7na annulata, 

 Schulz. {omicronaria, Hb.) were captured. The larvae of Chora 

 lichenaria, Hufn., was searched for, but failed to put in an appear- 

 ance. Almost every bush of spindle was swarming with the larvse of 

 Hyponomeuta evonymelia, L. A short lane produced Saperda populnea 

 and the lovely nest of a wood warbler {Philloscopus sibilatrix, Bech.) 

 with seven eggs. Close by, among some young birch and under- 

 wood, Euchelia JacobcBOi, L., was in full force, and an odd Pararge 

 megcera, L., was noted with Melanippe montanata, Bork. Here, 

 too, our botanists got rewarded, for spikes of Orchis mascula, L., 

 were found with O. maailata, L., not yet in flower. Wandering on 

 through the fields, the beautiful larvse of Diloba cceruleocephala, L., 

 were seen defoliating the sloe ; and E. albulata, Schiff., was in 

 swarms flying over the grass in the field next the Guildford Road. 

 Geometer larvse, including the beautiful Hybernia defoliaria, L., 

 seemed plentiful wherever any beating was done. Crossing the road 

 by the church we took the path leading to the sheep leas. Under 

 the beech trees on the right were many spikes of Cephalanthera 

 grandiflora, Bab., with a few Listera ovata, Br. There was also 

 Daphne laureola, L. When the open leas were reached, there were 

 the blues, Z. astrache, Bgstr., and L. icarus, Rott.^ with C. pamphilus
