very strangely only one or two Chrysophanus phlceas, L.,were 

 observed ; perhaps the most beautiful series in the exhibit 

 was that of Zygmia faiista, L., a species which was fairly 

 common. There was also a long series, including both the 

 red and blue-winged forms of the pretty Orthopteron CEdipoda 

 fasciatuni, Fisch. 



Mr. W. A. Pearce exhibited beautiful series of four species 

 of Lycaenidae, from Pennsylvania, viz., Feniseca taj'qninius, 

 Fab., LyccEna pseiidargioliis, Bd. (both spring and summer 

 broods), L. comyntas, Godt., and TJiecla edwardsii, Saund. 



Mr. Auld exhibited, on behalf of Mr, W. H. Tugwell, a 

 series of the York City form of Spilosoma lubricipeda, which 

 he stated Mr. Tugwell proposed to name var. eboraci ; and 

 also series of vars. radiata ^.Vid. fas data. Mr. Auld said that 

 surprise had been expressed at the number of radiata extant 

 in so short a time, but as one female lays as many as 700 

 eggs, and the species could be reared very easily, it was not 

 improbable that quite 500 imagines might be obtained. Of 

 these, supposing only 200 were females, it could be seen that 

 in the third generation an enormous number would be pro- 

 duced even by one collector. Mr. Carrington stated that very 

 little attention had hitherto been paid to the artificial selec- 

 tion of Lepidoptera, and considering that many animals and 

 birds produced extraordinary variation under man's guidance, 

 it was not surprising that such varieties as had been exhibited 

 should have been obtained in considerable numbers. 



Mr. Carrington exhibited a shell of Helix poinatia, L., 

 which he had cut and ground to show the arrangement of the 

 spiral and the smooth internal layer. He stated that the 

 mollusc was surrounded by a viscid liquid, which it had 

 secreted, and which formed an excellent varnish if rubbed 

 over the outside of the shell, making it very glossy. He 

 considered this varnish to be a solution containing silica. 



Mr. Jenner Weir exhibited a new species of the Limnaine 

 division of the Euploeinas, which he had described, and was 

 about to figure under the name of Cadiiga a^owleyi. This fine 

 species was from North Eastern Borneo. 



A paper by Mr. Lewcock, entitled, " Coleoptera collected 

 at Eynesford on June 20, 1891, and at Oxshott on June 10, 

 1892, during the Society's Field Meetings on those dates," 

 (page 84), was then read, and examples of the species re- 

 ferred to exhibited. 



Mr. Carrington referred to the dark varieties of many 

 species which had recently been exhibited at the Society's 

 meetings, and stated that melanism ^^as local variation pro-
