Mr. R. Adkin exhibited full-fed larvae of Ephestia Kilhniella. Mr. Cooper said 

 he had taken this moth very freely in a bakery at Leytonstone, and had found the 

 larvae feeding in great numbers ; there was very little flour stored in the bakery, but 

 the larvae fed on the dust collected on the beams ; he had taken the species for the 

 last four years. Mr. Billups exhibited living examples of Hydaticus seminiger, De Gr.

Mr. E. Meyrick communicated a paper " On the Pyralidina of the Hawaiian 

 Islands," the materials for which paper consisted principally of the collection of 

 Lepidoptera Heterocera formed by the Rev. T. Blackburn during six years' residence 

 in the Hawaiian Islands. Mr. Meyrick pointed out that the exceptional position of 

 these islands renders an accurate knowledge of their fauna a subject of great interest. 

 He stated that of the fifty-six known species of Hawaiian Pyralidina nine had 

 probably been introduced through the agency of man in recent times ; but he 

 believed the remaining forty-seven to be wholly endemic ; of these latter the author 

 referred twenty-six species to the Botydidce, twelve to the Scopariadw, four to the 

 Pterophorida, three to the Crambidce, and two to the Phycitidce. Dr. Sharp, 

 Mr. McLachlan, Dr. Mason, and Mr. E. B. Poulton took part in the discussion 

 which ensued.— H. Gross, Hon. Secretary.
