ABSTRACT OF PROCEEDINGS. 



FEBRUARY 8th, 1906. 



Mr. R. Adkin, F.E.S., President, in the Chair. 



Mr. W. J. Kaye exhibited a number of preserved larvae of 

 Cidaria sagittata, and made mention of the marvellously close 

 resemblance they had to their food, Tlialictrum flowers, but, 

 notwithstanding, they were greatly persecuted by ichneu- 

 mons. It appeared likely, therefore, that the latter associa- 

 tion with the larvae was very ancient, and probably before the 

 larvae had attained such a close resemblance to their food- 

 plant. The attacks of birds were, however, probably largely 

 evaded. Mr. Kaye mentioned that he had found as many 

 as fourteen larvae on one spike of flowers. 



Mr. Robert Adkin exhibited specimens of Psyche villosella 

 and P. opacclla, together with their larval cases, preserved 

 larvae, and pupal skins, and pointed out the difference 

 between the two cases, those of opacclla being more compact 

 in structure than those of villosella. It was stated by Dr. 

 Chapman that a loosely thatched case generally produced a 

 6*, a close one a ? , imago. 



Mr. W. J. Lucas exhibited : 



(1) The crustaceous lichen, Graphis scripta, growing on 

 the bark of holly from the New Forest. 



(2) Badhamia varia, one of the endosporous Mycetozoa, 

 found by Master G. Step on the under surface of a branch 

 of a large living oak in Ashtead Woods, February 3rd, 

 1906. 



The remainder of the evening was devoted to an exhibi- 

 tion of lantern slides : 



(1) Mr. West, of Ashtead, showed a large number of 

 sections of woods. 



(2) Mr. Lucas showed slides of rare plants, life histories 

 of insects, protective resemblance, etc.
