Exhibitions, Memoirs, &c. 



Mr. Barraud exhibited a very minute wasp's nest, found inside 

 a sparrow's nest ; the outer globular covering of which was about 

 one inch and a quarter long, and seven-eighths of an inch in 

 diameter, and appeared of a texture nearly resembling saw-dust 

 or fine sand. In the interior at the base were fourteen cells 

 commenced, each not being above two lines wide. 



Mr. Raddon mentioned the arrival of three more specimens 

 of Goliathus regius at Bristol, brought by vessels trading to 

 Africa. 



Mr. W. Bennett exhibited a living specimen of Calosoma 

 St/cophanta, captured between Ramsgate and Broadstairs on the 

 20th June ; the day was calm and fine, but not unusually hot ; 

 it was slightly injured in the elytra ; it had been kept alive by 

 feeding it with moths, and it was stated that Mr. Desvignes had 

 kept an Austrian specimen alive four months by feeding it on 

 caterpillars. Mr. Hope stated, that he had obtained sixteen spe- 

 cimens in one season, which were found at the roots of oaks in 

 the avenue leading to Eaton Hall. All these specimens were of 

 a green colour, and destitute of the coppery tint on the elytra. 

 Mr. Newport also mentioned the capture of a specimen in Heme 

 Wood, between Heme and Canterbury. 



Mr. Westwood exhibited three species of a singular Mexi- 

 can genus of Malacoderm beetles, Chactas, the males of which 

 (contrary to the ordinary rule amongst insects) are much larger 

 than the females, and have the elytra singularly dilated ; and 

 observed, that amongst cornuted insects, the males were also 

 generally larger than the females. Mr. Shuckard also men- 

 tioned, that in the genera ^pis and Anthidium the same diversity 

 prevailed, although in the other genera of bees the females were 

 the largest. 



Mr. Westwood also exhibited a species of the curious Orthop- 

 terous genus Hymenotcs, W. (Proc. Zool. Soc. — ChoripJiyllum, 

 Serv.) from Manilla. A species of this genus had been known 

 to Linnaeus and Fabricius, who, deceived by its analogy with the 

 Mcmbracides, had described it as a species of Cicada. (See the 

 memoir on this genus subsequently published in the Magazine of 

 Natural History). 



Mr. Hope read the descriptions of a portion of a splendid col- 

 lection of insects made in Assam by Mr. Griffith, and forwarded 

 to R. H. Solly, Esq , which were exhibited, and made some 

 verbal remarks upon others in the collection.
