Election of a Member. 



R. B. Were, Esq., 35, Osborne Terrace, Clapham Eoad (formerly a Subscriber to 

 the Society), was balloted for and elected a Member. 



Exhibitions, 



Mr. Stevens exhibited some Lepidoptera and Coleoptera sent from Port Natal by 

 M. Gueinzius: amongst the former were specimens of Charaxis, Zoolina, Saelamis, 

 Cloanlha, and some beautiful species of Bombycidae ; also an Adela closely resembling 

 the A. Degeerella of Europe : the Coleoptera included Hypselojjenia geotrupina, 

 Sternetornus Bohemanni, Eunostus Gueinzii, and eight species of Paussus. 



Mr. Stevens observed that Eunostus Gueinzii was stated by M. Gueinzius to be 

 nocturnal in its habits, and this appeared to be generally the case with pale-coloured 

 insects : the pale Megacephala taken by Mr. Bates on the Amazon was said by him 

 to be a strictly nocturnal species. 



Mr. Smith observed, in corroboration of this theory, that the pale-coloured Vespa 

 Doryloides, Sauss., lately sent home by Mr. Wallace from Borneo, was said to be 

 found at night only, which was the more interesting as no other species of wasp was 

 yet known to be nocturnal. 



The following notes, which accompanied the collection exhibited by Mr Stevens, 

 were communicated by M. Gueinzius : — 



Oti the Habits of Paussidce, ^c, 



" Except the specimens of Paussidge which have been attracted by candle-light, I 

 have never found a specimen elsewhere than in ants' nests, except one, and that a new 

 species, in this collection, which I found in the hot sunshine, sitting upon a blade of 

 grass, no doubt quite accidentally. They all live with species of ants which are car- 

 nivorous: Cerapterus, Pleuropterus and Pentaplatarthrus with different larger species, 

 but the true Paussi seem to live only with our small species ; at least I have found P. 

 cucullatus, P. Dohrnii, P. Latreillii, P. Shuckardii, and three other species in the 

 collection, all with one and the same species. 



" One night last summer I heard a slight tap on a window-pane, as from a grain 

 of gravel : upon going out with the candle I found it was a Paussus (similar to 

 Dohrnii), of which I had not seen a specimen for some years: not half an hour after- 

 wards I heard the same sound on the same window, and found a second specimen. 

 Although I did not observe the sex, there is little doubt that the first specimen was a 

 female, and the second a male. In a number of instances I have observed that the 

 females of Coleoptera move some time before the males. I observed one morning a
