Donations to the Library were announced, and thanks voted to the 
donors. 
Mr. Richard S. Standen, of Holmwood Lodge, Surbiton, and Mr. T. W. 
Wonfor, of 38, Buckingham Place, Brighton, were ballotted for and elected 
Members. 
Mr. Jenner Weir exhibited three specimens of an Atypus taken on a bank 
near Lewes; they were stated to erect a pile of small pieces of chalk in 
front of their burrows. Mr. Weir also exhibited a remarkable spider from 
Madagascar, and a small living spider (Philodromus), marked and coloured 
in imitation of lichen, which he had beaten out of trees in the New Forest. 
Sir Sidney Saunders stated that the Atypus was A. Sulzeri, Koch. 
Mr. M‘lachlan exhibited a small collection of dragon-flies of the genus 
Euthore, in illustration of a paper entitled “ Calopterygina collected by 
Mr. Buckley in Ecuador and Bolivia.” The collection contained a fine 
series of both sexes of a new species, Huthore mirabilis. 
Mr. Meldola exhibited a remarkable specimen of Leucania conigera taken 
at Willesden. ‘The colour and markings of the fore wings were reproduced 
on the lower half of the left hind wing. 
Mr. Meldola then read some extracts from a letter from Dr. Fritz 
Miller to Mr. Charles Darwin, dated from Santa Caterina, Brazil, 27th 
November, 1877. 
The Secretary called the attention of the members to the approaching 
International Entomological Exhibition to be held at the Royal Westminster 
Aquarium in March. He also exhibited, on behalf of Capt. Elwes (who 
was present as a visitor), a series of coloured illustrations of butterflies, 
printed from nature by a new process invented by Dr. Sériziat, of Collioure 
(Pyrenées Orientales), France. The inventor states that the “colouring 
matter is fixed by means of a special adhesive and a press; the bodies are 
painted in water-colours after nature.” 
Mr. G. C. Champion exhibited twelve species of the genus Cetonia, taken 
by Mr. J.J. Walker, of H.M.S. ‘Swiftsure,’ at Besika Bay, Salonica, 
Pireus, and other Mediterranean localities. He also exhibited a specimen 
of Anthicus bimaculatus, a rare British beetle, taken near New Brighton by 
Mr. J. T. Harris, of Burton-on-Trent. 
Mr. J. W. May exhibited a specimen of Carabus intricatus taken at 
Fulham. 
Mr. H. Goss called attention to the occurrence of sexual dimorphism in 
Erebia Medea, and exhibited specimens of both forms of the female. He 
stated that he had obtained specimens of both forms nearly every year for 
the last sixteen years from Silverdale, Lancashire, and that one form was 
quite as common as the other. The principal difference between the two 
forms consisted in the colouring of the discal band. In one form, which 
Mr. Goss believed to be the typical form, the discal band was bluish ash-
