 and also at Hornsea, on the east coast of Yorkshire.

' Descriptions of some Species of Brazilian Ants belonging to the 

 Genera Pseudomyrma, Eciton and Myrmica (with Observations on 

 their Economy by Mr. H. W. Bates.)' By Frederick Smith, Esq. 



Mr. Smith's paper completes the Catalogue of the British Formi- 

 cidae, and will be particularly useful to the students of British Ants, 

 more especially as it corrects some recently-made errors in the 

 nomenclature of our species, for example : — 



Myrmica scabrinodis of Nylander, Foerster and Smith = Myr- 

 mica rubra, Curtis, Trans. Linn. Soc, xxi. 213. 



Myrmica rugiuodis of Nylander, Foerster and Smith = Myrmica 

 vagans, Curtis, Trans. Linn. Soc. xxi. 213. 



Myrmica sulcinodis of Nylander and Smith = Myrmica per- 

 elegans, Curtis, Trans. Linn. Soc. xxi. 214. 



This shows how necessary it is to keep pace with the progress of 

 our science on the Continent, if we wish to establish (and who does 

 not?) uniformity of nomenclature. 



The paper on the genus Stenus is also of great value, and reflects 

 great credit on the patience and perseverance of its authors.
