Forest during the past few years, and only one had been met with 

 in the daytime. He contributed the following notes on the varia- 

 tion and the aberration he exhibited : — 



General classification of )nales. — I. F.W. of uniform colour, 

 ranging from yellow to dark brown, speckled with black; H.W. 

 white, faintly speckled. II. F.W. pale or dark brown, with sub- 

 marginal band and faint discal spot ; H.W. white, speckled, with a 

 faint central spot. III. F.W. of whitish or yellowish ground 

 colour, with orange-brown submarginal band and a distinct discal 

 spot ; H.W. white, faintly speckled, with black central spot. IV. 

 F.W. of pale to deep yellowish ground colour, with chocolate brown 

 submarginal band and a large discal spot ; H.W, white, faintly 

 speckled, with black central spot, some showing a slight indication 

 of a submarginal line. V. F.W., ground colour rich brown of 

 varying depth, with deep chocolate submarginal band and discal 

 spot ; H.W. more faintly speckled than any of the former, many 

 showing development of a submarginal band, VI. F.W. heavily 

 suffused with black of varying intensity, the submarginal bands and 

 discal spots being obliterated in those with the darkest scaling ; 

 H.W. suffused with black of varying intensity, the body is also 

 noticeably affected by melanism, the black scaling of the wings 

 extending over the body. 



General classificatum of females. — I. to V, inclusive. The ? 

 has a body of a mottled appearance, both on the upper- and under- 

 sides, the mottling also extends over the legs. VI, The ? has a 

 black body, both upper- and undersides, only the thorax being 

 mottled ; the legs have the least traces of white at the joints only, 



Mr. B. S. Williams showed a few specimens of H. aurantiaria, 

 one being rather remarkable in having a suffused and purplish 

 colour with nervures prominent from their orange red coloration. 

 The Finchley H, defoliaria this season had been somewhat smaller 

 than usual. 



The President remarked on the three areas where the melanism 

 of these species appears to predominate, Epping, Delamere, and 

 Yorkshire. 



Mr. Porritt reported that he had found Phigalia pedaria fully out 

 near Huddersfield, on January 17th of this year, and had seen one 

 specimen as early as December 4th in 1919, Mr. Tonge reported 

 the species on January 16th, at Redhill, Surrey.
