Mr. B. S. Williams exhibited two aberrations of ^Jamestra 

 {Barathra) hrassica, a pale form with aberrant shaped stigmata, 

 and a black suffused form. 



Mr. Curwen exhibited a number of species of anthrocerids, and 

 suggested that a discussion on the group might occupy an evening 

 during the winter session. 



SEPTEMBER 12th, 1914. 



Field Meeting held at Byfleet. 



Stanley Edwards, F.L.S., F.Z.S., Coniliictor. 



The morning party of seven journied to Woking, and worked 

 along the canal from thence to Byfleet. Many larvte were taken, 

 but nothing of any moment, except Hadena adasta, to add to the 

 list already published as the results of previous visits. Among the 

 captures Mr. Brooks reports an imago of Hadena jirotea. Several 

 species of saw-tly were noted in the larval stage, and Mr. Step 

 records the larva of Atltalia scittellar'uc, a local species, which 

 Cameron mentions as only recorded from Gloucester. It is one of 

 the prettiest of the saw-fly larvte, its colour being black freely 

 spotted with white. It feeds on skull-cap, preferring the flowers. 

 Piecilosoma indceratimi, a species given by the same author as com- 

 mon in Scotland, was met with in great abundance on alder. Of 

 this species Norwich is given by Bridgeman as the only locality. 

 Iiii pat tens bi flora (fnlva) in full flower was the most noteworthy 

 botanical record. 



The Society has been to Byfleet on several occasions, but scarcely 

 ever has it had a wholly fine day. This visit was no exception to the 

 previous experience, except that perhaps it was worse than any of 

 its predecessors, for the rain started at 1.45 p.m. and did not cease 

 for the remainder of the day. The six who formed the afternoon 

 contingent were only able to take shelter, working for insects being 

 quite out of the question.
