" Sunius neglectus is not yet iu the British list, and is very closely allied to 

 S. angustatus, Erichson; probably they are generally mixed in collections. 

 I have had them separated for several years, and when on a visit recently to 

 Mr. Crotch, with his assistance was able to determine the species. From 

 angustatus it differs in having the head, thorax and elytra proportionally 

 shorter and more convex, less closely punctured, and therefore more shining. 

 Angustatus has a more linear aspect, and the whole insect is more opaque. In 

 angustatus, again, the elytra have a tendency to become pale, particularly at 

 the shoulders, and the apex is more broadly testaceous, thoug[h this colour does 

 not usually extend so far up the suture as in neglectus. I send two specimens 

 of angustatus for comparison with what I regard as neglectus ; one of them is a 

 very beautiful bimaculate variety." 



Mr. Albert Miiller exhibited specimens of an Indian gall formed on the mid- 

 rib of the leaf of a species of Gnetum ; the galls were of the size of a small 

 acorn, consisted of a single cell, and were placed longitudinally along the 

 mid-rib on the under side of the leaf. 



Mr. Janson exhibited a large number of butterflies collected by his son, 

 Mr. E. M. Janson, at Chontales, Nicaragua, in November and December, 

 1869. 



Mr. Butler exhibited specimens of Argynnis Adippe and Niobe, and inter- 

 mediate forms, in corroboration of his previously expressed opinion that the two 

 were not distinct species. 



Dr. Wallace, on behalf of Mr. Harwood, exhibited some dark suffused 

 varieties of Melitsea Athalia; and specimens of Herminia derivalis. 



Mr. Sfciinton exhibited Cosmopteryx Lienigiella, bred in England from 

 Eussian larvee. The larva was discovered two years ago, near Riga, feeding in 

 the reed (Arundo) : its habits once known, it had since been found in this 

 country, and Mr. Stainton had within the last two or three days bred the moth 

 from a native larva. 



Dr. Wallace addressed the Meeting on the progress and prospects of serici- 

 culture in this country and some of our colonies. He exhibited English-bred 

 specimens of Antheraea Yamamai, remarkable for their great variation in tint, 

 from ashy brown, through various shades of red, to a bright yellow or pale dove- 

 colour; also English and Austrian cocoons of the same species, which had 

 succeeded better in 1869 than in 1868 : he considered the Eastern counties of 

 England unfavourable on account of the dry warm temperature, and that the 

 more humid climate of the Western coast was better suited to the insect ; an 

 equable temperature from 60° to 70° was requisite, with abundant ventilation 

 and great cleanliness : in Moravia the Baron de Bretton had reared 28,000 

 cocoons in 1869, w^hich were all devoted to the production of eggs: and 

 Dr. Wallace thought the efforts now made in Europe to acclimatize this 

 species would very shortly be successful. He also exhibited specimens of 

 Bombyx Peniii obtained from cocoons imported from China, and some English
