Dr. Chapman exhibited the cocoons of Niidaria niurina 

 and Enchromia lethe with larval hairs similarl}' dispersed. 

 The different effect is due to the cocoon being slight in the 

 one case, dense in the other, and the hairs few and long in 

 A'', nmrina, and abundant and comparatively short in E. lethe. 

 In both, the hairs are laid on as a thatch and inverted when 

 the cocoon is placed as shown. In the case of Enchromia the 

 thatch probably is useful as a thatch shedding in rain, etc. 

 In Nudaria the arrangement has degenerated so as only to 

 represent perhaps a spider's nest, as such often appear in 

 crannies in walls and places such as A^. murina inhabits — 

 or it may be the spider-nest process has, so to speak, 

 accidentally taken an orderly arrangement of the hairs, 

 giving a starting-point for the development of a useful thatch, 

 as in Enchromia. 



Mr. Step exhibited a specimen of the winter heliotrope 

 {Petasites fragrans), received from Shanklin, where it has 

 become established as a wild plant. Its period of flowering 

 is from November to February. 



Mr. Kirkald}' gave an account of a tour he took in igo2 

 through Italy and Switzerland (see page 37). 



JANUARY Sth, 1903. 



Mr. F. NoAD Clark, President, in the Chair. 



Mr. Oldaker, of Dorking ; Mr. Spityby, of Canonbur}- ; 

 Mr. Priske, of Acton ; Mr. Pratt, of Richmond ; and Mr. 

 Goulton, of Balham, were elected members. 



Mr. Goulton exhibited a very light form of Ematurga 

 atomaria from Folkestone, and an aberration of the same 

 species from Box Hill. In the latter the marginal and sub- 

 marginal areas were uniformly dark. It was remarked that 

 the light specimen was a good example of a form of the 

 species usually occurring at Dover and Folkestone. 



Mr. Chittenden exhibited a short series of Ephyra pendii- 

 laria from Staffordshire, Ashford district, and Chislehurst. 

 Those from Staffordshire were bred, and were of the 

 beautiful rosy form, var. siibroseata, which is dark in ground 

 colour and suffused with a rosy tint. The Chislehurst 

 specimens were very pale in ground colour, with less pro- 

 nounced markings. The Ashford examples were banded 

 with a lighter shade. 



Mr. Lucas exhibited, for Mr. Kemp, an aberration of the
