150 IMPORTANT NEW WORKS ON ENTOMOLOGY. 



Geology has long been a fashionable science, and the Presi- 

 dent of the British Association for the ensuing meeting 

 (the Duke of Argyll) is known as a good geologist; why 

 should not Entomology be also represented in the House of 

 Lords and in the Cabinet? — Editor of the Entomologist's 

 Annual. 



THE BUTTERFLIES of GREAT BRITAIN, with 

 their TRANSFORMATIONS. Delineated and described 

 by J. O. Westwood, Esq., F.L.S., with Nineteen Coloured 

 Plates. London : W. S. Orr & Co. Price 15s. 



This volume, according to the preface, may be considered 

 as a re-issue of " British Butterflies and their Transforma- 

 tions," a work which, generally known as " Humphreys and 

 Westwood," has never been regarded with favour by the 

 Entomologists of the present day ; but the object being ' to 

 re-issue it at a price which would place it within the reach of 

 every student,' the size as well as the bulk of the work has 

 been reduced, and Mr. Westwood has himself drawn a set of 

 fresh plates, and only those species are introduced which 

 are enumerated as British in Stephens's Museum Cata- 

 logue : it may therefore be readily understood that it is a 

 vast improvement on the work of which it professes to be 

 a re-issue, and will no doubt be found of very great use by 

 incipient collectors. It is very interesting to notice the ex- 

 tent of our ignorance on many parts of the Natural History 

 of our few species of Diurnal Lepidoptera, some idea of 

 which may be formed from the following queries, to which 

 we should be very glad to receive answers. 



1. Papilio Machaon. Are there one or two broods in 



the year ? 



2. Colias Hyale. Is this double-brooded on the Con- 



tinent ?
