Free State, specimens of which had been forwarded to Mr. J. H. Gurney, 

 and determined by Dr. Giinther. 



Mr. Martin Jacoby gave an account of a small collection of Coleoptera 

 obtained by Mr. W. L. Sclater in British Guiana. 



Prof. G. B. Howes read a paper on an hitherto unrecognised feature in 

 the larynx of the Anurous Amphibians. This was the existence in many 

 individuals of various species of a rudimentary structure, which appeared 

 to correspond to the epiglottis of Mammals, and which in some instances 

 attained a remarkable development as an organ of voice. — P. L. Sclater, 

 Secretary. 



Entomological Society of London. 



June 1, 1887. — Dr. David Sharp, F.Z.S., President, in the chair. 



Mr. PhiHp Crowley exhibited the following specimens of Diurni, from 

 the Kareen Hills, Burmah: — Pupilio Zaleiicus, H.e\v.,Papilio Adanisoni, 

 Smith, Papilio ? sp. (male and female), and Nymphalis Nicholii, Smith. 



Mr. T. R. Billups exhibited several specimens of an ant found at Kew, 

 frequenting a species of palm from Tropical Australia, and which had been 

 determined as Tapinoma melanocephalum ; also living specimens of Carabus 

 auratus, from the Borough Market, and of a species of Blaps from Northern 

 Africa. 



Mr. Waterhouse exhibited a specimen of a Brazilian Locust, Cono- 

 cephalus ? sp., which he had for some time preserved alive, -and which had 

 only died that same morning. He called attention to the change of colour 

 which he had observed in the eyes of this insect ; in a bright light they 

 were dirty white or horn-coloured, with a black dot in the middle ; but at 

 night, or if the insects were confined in a dark box, they became altogether 

 black; shortly after death, also, the eyes became black. Mr. M'Lachlan 

 observed that he had noticed a darker spot in the centre of the eye in certain 

 Ephemeridse, and in other Neuroptera. The discussion was continued by 

 Dr. Sharp and others, but no one seemed to be able to account for the 

 alteration in question. 



Lord Walsingham exhibited specimens of Caterenina terehrella, Zk., 

 a species lately taken in Britain, which he had caught in Norfolk, and bred 

 from fir-cones gathered in the same locality. 



Mr. Meyrick read two papers, " On Pyralidina from Australia and 

 the South Pacific" and " Descriptions of some exotic Micro-Lepidoptera." 

 In these papers at)out sixty new species were described. A discussion 

 ensued, in which Dr. Sharp, Mr. Staintou, Mr. M'Lachlan, and others took 

 part. Mr. Meyrick stated that, as far as the Pyralidina were concerned, 

 Australia could not be I'egarded as a separate region, for a large number 

 were not endemic, but appeared to have been introduced from the Malay
