The Eev. F. D. Morice, the President, then delivered an Address on " The 

 Saws (so-called) of the Saw-flies," at the close of which Dr. F. A. Dixey pro- 

 posed, and Prof. W. Bateson seconded a vote, authorizing the publication of 

 the Address, and thanking the President for the same, and for the series of 

 seven plates which he had presented to illustrate it, and also for his services 

 during the past session. This was carried unanimously, and the President 

 replied with a few words of thanks. 



A vote of thanks to the Officers for their services during the past year 

 was then proposed by Mr. C. O. Waterhouse, in reply to which Mr. A. H. Jones 

 and the Eev. G. Wheeler, the only two Officers then present, returned thanks. 



Wednesday, February 1th, 1912. — The President in the Chair. 



The Pi-esident announced that he had nominated as Vice-Presidents for the 

 present session Mr. A. H. Jones, Dr. Malcolm Burr, and Mr. J. H. Diirrant. 



Mr. W. E. Sharp exhibited specimens of Carpophilus d-pxtstulatus, F., and 

 C. obsoleUis, Er., taken under bark of beech trees near Doncaster in October, 1911 ; 

 the former having been recorded from the same locality only on a few occasions 

 diu'ing recent years, and the latter never having been known to occiu- under 

 natural conditions in England previously. Mr. Champion called attention to a 

 paper by Mr. H. C. Bryant, recently published in an ornithological periodical, 

 the "Condoi-," for November, 1911, entitled " The relation of birds to an insect 

 outbreak in northern California dtiring the spring and summer of 1911." The 

 data collected showed of what value birds may be in the checking of an insect 

 outbreak rather than their value in the prevention of such an outbreak. 

 Prof. Poulton exhibited a large but not quite complete series of the members of 

 the important combination of the Geometrid moths of the genus Aletis, and 

 their mimics from the neighbourhood of Entebbe, collected, between May 23, 

 1909, and September 14, 1910, by Mr. C. A. Wiggins, D.P.M.O. of the Uganda 

 Protectorate. Also part of an all-anthedon family recently bred by Mr. Lamborn 

 at Oni Camp, seventy miles east of Lagos, from an anthedon female parent, and 

 part of an all-duhius family also bred from an anthedon female. The facts 

 indicate that in the fii-st family a recessive female had paired with a recessive 

 male, in the second that a recessive female had paired with a dominant male. 

 There can be little doubt that the pattern of anthedon conforms more closely to 

 that of the genus than the pattern of dubius, and that the dominant form is 

 therefore the more recent development. Prof. Poulton read a note from Oni 

 Camp, Lagos, showing that butterflies may be a natviral- food of monkeys. He 

 also di-ew attention to the following observation i-ecently made by Mr. Lamborn 

 at Oni:— "On December 27 I saw a male Ghdophrissa saba courting a female. 

 She was resting on a leaf with wings expanded. Her abdomen was raised to an 

 angle of rather more than 45° to the thorax, and two little tufts very similar to 

 those possessed by male Danainse protruded from the anal extremity."
