The paper led to a long discussion, chiefly on the so-called 
‘‘dry-season’”’ and ‘‘ wet-season forms,’’ between the Presi- 
dent, Mr. Jacoby, Mr. Tutt, and Mr. Merrifield. The latter 
speaker stated that he had been unable experimentally to 
modify the colour and markings of Lepidoptera by variations 
in humidity. Mr. Tutt believed that Mr. Doherty had 
obtained ‘‘ wet-season forms” of Oriental species by keeping 
the pupa in a moist atmosphere.

tion Committee of the Royal Society and British Association. 
Mr. FI’. C. Adams exhibited rare Diptera taken in the New 
Forest during the preceding year, and read the following 
notes :— 
‘Tipula, sp. n.; a small species taken in my garden at 
Lyndhurst, May 28th, and submitted for identification to 
Mr. Austen, who regarded it as probably new. 
** Platyura marginata, Meig. It is doubtful whether this 
should be called rare, but I have not yet found it common in 
the New Forest, and it was unrepresented in the British 
Museum Collection. 
‘* Nephrocerus flavicornis, Zett. This very rare fly has only 
been taken twice in this country, on both occasions by myself. 
The first, taken on June 16th, 1894, in Park Ground En- 
closure, is in the National Collection; the second was taken in 
my garden, not more than two hundred yards from the same 
spot.
