mimetic resemblance to them. The exhibitor stated that his collection should 

 prove interesting as regards seasonal forms, especially in the Acrniiiife and Pierinae, 

 of which he showed an additional example.— H. Kowland Brown, Ron. Secretary. 



Wednesday, November 1th, 1906. — The President in the Chair. 



Mr. Grerard H. Grurney, Keswick Hall, Norwich ; Mr. Harold Armstrong Fry, 

 P.O. Box 46, Johannesburg, Transvaal Colony ; Mr. Frederick Albert Mitchell- 

 Hedges, 42, Kensington Park Gardens, London, W. ; Mr. Grordon Merriman, 

 Trinity Hall, Cambridge ; Mr. Percy A. H. Muschamp, 20, Chemin des Asteres, 

 Geneva; and Mr. Oswin S. Wickar, Crescent Cottage, Cambridge Place, Colombo; 

 were elected Fellows of the Society. 



Mr. W. J. Lucas exhibited a photograph of Panorpa germanica, practically 

 immaculate, taken by Mr. E. A. Cockayne in Sutherlandshire, and a typical form 

 for comparison, corresponding appar«ntly to the borealis of Stephens. He also 

 showed other species of the genus to illustrate the range of spotting on the wings 

 of both sexes. Mr. G. C. Champion, a long series of a Heiiicopus (probably 

 M. spiniger, Duval) from El Barco, Galicia, Spain, to demonstrate the dimorphism 

 of the females : one form having wholly black hairs, and the other wholly white 

 (sometimes with a few black ones intermixed), the males showing no variation in 

 this respect. Mr. H. St. J. Donisthorpe, seven specimens of Prionocyphon .serri- 

 cornis, Miill., bred from larvae taken in the New Forest in July, living larvae, and 

 a larva and pupa figured of the same, and read a note on the species. Dr. T. A. 

 Chapman, a collection of butterflies, made in Galicia last July, including Lycxna 

 idas, hitherto reported only from the Sierra Nevada. It occuin-ed at an elevation of 

 4500 to 5000 feet, and only where there grew a species of Erodium ; also specimens 

 of L. astrarche from practically the same ground for comparison, and L. argus {segon) 

 from the same district. These, while very close to the vars. hypochiona and 

 bejarensis, differ, however, in a certain proportion of the specimens presenting the 

 red of the marginal " peacock eyes " on the upper surface of the hind-wings of the 

 males. The Hon. N. C. Rothschild, branches of Viburnum lantana showing the 

 mines of Sesia (Mgeria) andreniformis, now discovered bj him as the food-plant 

 of the species in Britain for the first time. Mr. E. Dukinfield Jones, two species 

 of moths of the Brazilian genus Molipa, identical in appearance, bred from widely 

 different larvae. He also showed photographs of the larvae in situ. The President 

 mentioned a bug, Heterotoma merioptera, Scop., which Mr. Cecil Floersheim had 

 found very destructive to the eggs of Papilio machaon and P. asterias in his open- 

 air butterfly house. He said that it was remarkable to find that one of the Capsidx 

 was a carnivorovis species. Dr. F. A. Dixey, specimens of Pierine butterflies to 

 illustrate the various conditions under which white pigment might be replaced 

 by black. He said that in his opinion melanism, though it might arise as a 

 variation or sport, owed its establishment to the principle of selective adaptation. — 

 H. Rowland-Beown, Hon. Secretary.
