occurred. The larvae bunched up the twigs and leaves of 

 the juniper. A handful or two of these bunches produced 

 more than forty imagines. He stated that the insect could 

 be found along the old Roman Road at Mickleham, which 

 the Society visited in igoi. (2) A very variable series of 

 Pcedisca corticana taken on a wet day in July in Epping 

 Forest. The species was exceedingly abundant, literally in 

 clouds, and the variation was extreme. Some specimens 

 were of a deep brown-black, while at the other extreme were 

 examples showing a greenish tinge. The protective resem- 

 blance of the majority was exceedingly perfect, and the 

 numbers present on any one tree could only be observed by 

 disturbing them. (3) A male example oi Pechypogon barbalis 

 set to show the remarkable secondary sexual characters 

 existing in the extreme and fantastic development of tufts 

 and hairs on the fore-legs. No explanation of the way in 

 which these remarkable structures were of use to the species 

 was forthcoming. (4) Two varieties of the underside of 

 Polyonimatus icarus, taken at Banstead. The first, a male, 

 had the ocelli on the fore-wings either absent or much 

 reduced in size ; the basal spots were obsolete ; only four of. 

 the submarginal row were present, and the marginal mark- 

 ings were very faint ;. on the lower wing the submarginal row 

 was completely obsolete ; the discoidal and the marginal 

 markings only were left. The second example, a female, had 

 the submarginal row of spots much enlarged and intensified. 



Mr. Kaye exhibited — (i) A very fine female variety of 

 Fidonia atoinaria. The ground colour was very white and 

 much increased at the expense of the dark brown bands, 

 some portions of which had disappeared or almost dis- 

 appeared. (2) A bred series of Tiliacea (Xanthia) aurago from 

 ova deposited by a female taken at Worcester Park, Surrey, 

 at ivy. He stated that he had for years worked this same ivy, 

 but previously had taken but two specimens of this species. 



Mr. H. Moore read a paper entitled " A Visit to the 

 Forest of Arques," and exhibited a number of species taken 

 by him in the locality, especially referring to a series of 

 Ccenonympha arcania (page 30). 



Dr. Chapman read a paper entitled " On Inflation in 

 Insects" (page 22). 



Mr. Tutt said that Mr. Moore's paper called to mind 

 several strange, and as yet unsolved, problems of distribution. 

 One would expect at so short a distance from Britain to find 

 a fauna practically identical with that of the south of 

 England. Such, however, was not the case, for the character-
