referred to in his paper, several of them having been sent to 

 him from Lynmouth by Mr. C. A. Briggs. 



Mr. Alfred Sich exhibited an aberration of Lithocollctis 

 pomifolidla, in which the median streak is connected with 

 the first dorsal spot, giving the insect a different appearance. 



Three specimens of this aberration were taken at Chis- 

 wick off apple trees, during the present month. 



As a similar character is one of the points relied on in 

 separating L. viminetorum from L. salicicolclla, this aberration 

 of a species in which the median streak is normally not 

 connected may be worth notice. 



Mr. F. B. Carr exhibited larvae of Geomctra vcrnaria, some 

 of which had not yet shed their hibernating skin, while 

 others were more advanced. He also showed the ova of 

 Odontopera bidcutata. 



Mr. W. J. Kaye exhibited living larvae of Thccla pruni, and 

 remarked that the antipenultimate skin was of a beautiful 

 pink colour. 



Mr. Step exhibited for Mr. Lister a spray of an aberration 

 of the wood spurge {Euphorbia amygdaloidcs), in which the 

 flowers were of a whitish yellow, and some of the leaves 

 margined with white. It had been found at Eastry, Kent. 



Mr. Tonge exhibited a living specimen of Eupithecia 

 consignata, which he had just captured at Hayling Island. 



Mr. Newman exhibited a long bred series of Brcphos notha 

 from Worcester; a Polyommahis corydon var. fowlcvi ; Colias 

 cdusa, an intermediate, pale yellow form : an extreme melanic 

 form of Ematurga atomaria, bred, from Bur)' ; a form of 

 Chrysophanus pldceas, with the marginal spots on the underside 

 of the fore wings, enlarged to streaks ; specimens of Spilo- 

 soma lubricipcda of the third generation, Bexley, showing an 

 increase in the amount of black markings ; and a bred series 

 of Xotodonta trcpida, unusually large. 



Dr. Chapman exhibited the living larva of Thccla rubi. 



Mr. W. J. Lucas, B.A., read a paper on " Mosses," illus- 

 trated by means of lantern slides. After a few misnomers, 

 such as cup-moss, reindeer-moss, staghorn-moss, had been 

 referred to, a glance was taken at the position of the mosses 

 in the scale of vegetable life. Next the life-history of a 

 typical moss was discussed in some detail, the species 

 illustrated being generally Eunaria liygvomdrica. This is a 

 common plant on walls and paths and in a number of other 

 situations, and, as it readily produces spore-cases, it is well 

 adapted for close examination by any student of the British 

 mosses.
