of Liune is tlie form described under that name by Fischer. Dr. Stal further 

 said that he had never had any doubt about the species, as Fischer's migratoria 

 is the only species of locust which to his knowledge had ever been found 

 in Sweden. Mr. Smith remarked that Linne described migratoria in the 

 Fauna Suecica; Fischer was acquainted with both migratoria and cinerascens, 

 and figured their distinguishing characters, migratoria having a flat prothorax, 

 cinerascens an arched one ; and now to apply the name migratoria to the form 

 with the arched prothorax, on the strength of the specimens so labelled, would 

 only be productive of confusion. - 



Prof. Westwood said that he had examined Major Parry's specimen of 

 Nicagus obscurus (vide ante, p. iii.), and without saying to wha* group of 

 Lamellicorns the genus was properly referable, he felt clear that it did not 

 belong to any of the Lucanoid families. 



The Rev, H. S. Gorham sent for exhibition British specimens of Sunius 

 neglectus, Maerkel, accompanied by the following note : — 



" Sunius neglectus is not yet in 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, though 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 Gnetura ; 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 Melitaea Athalia ; and specimens of Herminia derivalis. 



Mr. Staiuton exhibited Gosmopteryx Lienigiella, bred in England from 

 Russian larvae. The larva w-as discovered two years ago, near Riga, feeding in 

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