delicate beauty of this species when bred, and to the marked 

 difference in shape of wing between the males and females. 



Mr. Step referred to his exhibit at the previous meeting of 

 the larv2e of a Cassida. He now exhibited the perfect insects, 

 which proved to be Cassida equestris. He stated that the 

 larvae were taken on July 13th ; they pupated about the 25th, 

 and the imagines emerged on the 31st. The imagines, as well 

 as the larvae, fed on the same plant. 



Mr, Fremlin exhibited a number of gall excrescences on 

 the twigs of hornbeam, which had been produced by a 

 species of Aphis. 



Mr. Edwards exhibited a number of rose leaves that had 

 been carved out by one of the leaf-cutting bees, presumably 

 Megachile centuncidaris, and stated that numbers of rose trees 

 were so disfigured. Mr. Adkin had observed the same thing 

 in his garden, but, curiously, only one kind of rose 

 tree had been attacked. The President had had a similar 

 experience. Mr. Turner called attention to the shapes of 

 the pieces cut from the leaves, the circular pieces forming 

 the partitions between the cells of the "■ nests " while the 

 longer oval pieces formed the lining. These bees had been 

 attached to his garden for years, and were accustomed to 

 make their tunnels under the cactus plants, or to avail them- 

 selves of the hollows in pieces of bamboo forming a plant 

 basket in his greenhouse. When first noticed in the garden 

 they attacked one rose tree only, but recently they had been 

 more indiscriminate in their ravages, cutting fuchsias, etc., 

 and even Virginia creeper. They had a very fine ichneumon 

 preying upon them. Mr. Montgomery and others continued 

 the discussion. 



Rev. F. H. Wood exhibited two spiders, Thcridion lineatnm 

 (females), one almost white; the other (a variety) with 

 red lines, enclosing a white space on the abdomen. The 

 red-lined spider was in spirits ; the other alive, and guarding 

 two egg-cocoons. Both spiders were found with a cocoon 

 each in a nettle and convolvulus leaf at Bromley on August 

 7th. The white spider killed the other while carried in a 

 larva-collecting tin. After the dead spider had been removed 

 the remaining one carried both cocoons from the leaves and 

 fixed them together on the tin lid, binding them to each 

 other. 



Mr. E. Step read the Report of the Field Meeting held at 

 Mickleham on June 22nd (page 17).
