Nemosoma elongata. — In 1860 I found a pair of this rare insect under the bark 

 of an old paling, on the bank of the 'Avon, near Bath. — V. C. de Rivaz, 4, 

 Shrewsbury Road, W. 



Occurrence of Cordulia a/rctica in Ireland. — T have in my cabinet a male of 

 Cordulia arctica, Zetterstedt, taken at Killarney, in 1862, by Mr. Birchall, and pre- 

 sented to me by that gentleman. This dragon-fly had hitherto only been found in 

 one British locality, Rannoch, Perthshire. Being undoubtedly a northern species, 

 one would scarcely have suspected its occurrence in the south-west of Ireland, but 

 Mr. Birchall remarks that he has found Caenonympha davus and Hadena rectilinecu 

 at the same place, neither of which occurs in the southern parts of England. De 

 Selys-Longchamps mentions that it has been taken on an elevated heath near 

 Arlon in Belgium, a locality still further south. The figure of the appendices in the 

 "Revue des Odonates" is very characteristic. — Robert McLachlan, Forest Hill, 

 15th July, 1864. 



Entomological Society of London, July 4th, 1864. — A. R. Wallace, Esq., 

 F.Z.S., Vice-President, in the Chair. 



Professor Westwood called the attention of the members present to a valuable 

 paper in the Transactions of the Russian Entomological Society, by Kolenati, on the 

 Nyeteriiidw, a tribe of flies parasitic on bats, in which several new genera were 

 founded. 



Mr. Wallace stated, that during his travels he had found a few of these insects 

 on bats, but that they were not nearly so abundant as the allied parasitic insects 

 on birds. 



Mr. Tegetmeier exhibited the piece of comb which he had mentioned at the 

 June meeting, showing clearly the line of new wax by which the bees had fastened 

 it to the frame, without any swarm having taken place, and when the workers were 

 of course unaccompanied by the queen. His attention had been first called to it by 

 observing some scales of new wax which had been dropped on the floor of the hive. 



Mr. Tegetmeier also exhibited some pieces of comb containing cells of various 

 sizes and forms, some of which were circular, some hemispherical, some pentagonal, 

 and others hexagonal, and observed, that accoi'ding to his views, the bees com- 

 menced by excavating hemispherical depressions, which as they became larger and 

 came into contact, of necessity assumed the hexagonal form. 



Mr. Smith read a short notice by Mr. Stone of the mode by which he had con- 

 trived to make the wasps erect the singular structures which had been exhibited at 

 the Juno meeting. 



Mr. Stainton exhibited some specimens of a Oelechia, which had been bi-ed by 

 Mr. Thomas Brown, of Cambridge, from larvae collected last autumn in the fens on 

 Lathyrus palustris. The insect had hitherto been supposed identical with the Con- 

 tinental nigricostella, which it closely resembled, but a comparison of bred specimens 

 of the two insects showed that they were distinct, and Mr. Stainton proposed for 

 the species bred from the Lathyrus palustris the name of Qelechia Lathyri. 



Professor Westwood stated, that from the larvas exhibited by Captain Cox at 

 the May meeting of the Society, and which had been found amongst bran, he had 

 reared some beautiful specimens of Pyralis fannalis. 



A paper by Mr. Roland Trimcn, on New South African Butterflies, in which 

 fifteen new species were described, was then read by the Secretary.
