found in Wicken Fen ; also a species of Noctua, which Mr. 

 Weir thought was probably a variety of Orthosia upsilon, 

 Bork. 



Mr. Step exhibited a number of photographs of Fungi, 

 and remarked that it was most difficult to preserve this large 

 group ; and not having time in which to sketch the different 

 species, he had recourse to photography, the result in most 

 cases being very successful, the exceptions being those of a 

 red colour. The specimens from which the photographs were 

 taken were all from Wimbledon Common, and comprised, 

 among others, Amanita muscarius, L., A. rubescens, Pers., 

 Lepiota procerus. Scop., Clitopilus orcella, Bull., Clitocyhe 

 nebularis, Batsch., Armillaria melleus, Fl. Dan., Boletus 

 scaber, Fr., Pholioia squarrosus, Mull., Russula heterophylla, 

 Fr., R. emetica, Fr., R. nigricans, Fr., etc. 



Mr. J. Jenner Weir said he should like to make a remark 

 on the rarity of Pieris napi, L., being desirous of sending ova 

 to America, as mentioned by him at the meeting on July 14th 

 last. He had spent a good deal of time in trying to take the 

 species, but with very little success. Of the spring emer- 

 gence he only captured one male, and of the autumn emer- 

 gence he only took two worn females, from which he failed to 

 obtain eggs ; he had not only failed himself, but friends who 

 had tried to assist him had been unable to do so. 



Mr. Carrington alluded to the extraordinary abundance 

 of Pieris brassiccz, L., and P. rapes, L., and remarked that 

 he had not noticed a single specimen of P. napi. 



Mr. Sheldon thought that P. napi was not so universally 

 distributed as the other two species. 



Mr. Cooper said he had written to a Scotch correspon- 

 dent to get him a series of P. napi, but he had been unable 

 to do so, although the other two species already referred to 

 had been common ; he had himself taken two or three females 

 but was unable to obtain ova. 



Mr. J. T. Williams said P. napi had been very common 

 at Foot's Cray, Kent ; and Mr. Tutt said it had appeared in 

 immense numbers at Deal.
