chair — to do all in his power to promote the interests of the 

 Society and the advancement of science, and, as he intended 

 to take some trouble towards these ends, he hoped he might 

 attain some of the moderate success which usually attends pn 

 well-meant exertion. 



Nomination of Vice-Presidents. 



The President then announced that he had appointed Dr. 

 Thomas Algernon Chapman, M.D., F.Z.S., Dr. Frederick 

 Augustus Dixey, M.A., M.D., and Professor Edward B. 

 Poulton, M.A., D.Sc, F.R.S., as Vice-Presidents for the 

 Session 1905-6. 



Exhibitions. 



Mr. H. St. J. DoNiSTnoRPE exhibited specimens of Oligota 

 grana/ria found in a granary in Holborn, the only other 

 localities reported hitherto being Shoe Lane, London, and 

 Scarborough. 



Mr. W. J. Kaye exhibited a specimen of the Erycinid butter-

 a mouse. The eye-spots of both fore- and hind-wings came 

 together in such a way as to resemble the two eyes of the 

 animal, while the outline of the wings so closed constituted 

 a family class-likeness to the sharp outline of the mouse's 

 head. 



Professor Poulton remarked that, as the eye-spot was 

 placed close to the body near the base of the wings, the 

 ordinary protective value thereof might be explained in some 

 such way. 



Dr. T. A. Chapman exhibited a variety of the female of 

 Lyceena melanops. As a mere aberration it was interesting ; 

 but it was of value as showing that the position in the genus 

 for long accorded to the species, whether by accident or design, 

 close to the avion — eujihemus group, was correct. 



The considerable extension of the blue in this specimen 

 showed up certain black spots on the upper surface of both 

 upper and lower wings, strictly similar to these characteristics 

 of the avion — euphemus group. He placed with it for illus-
