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 u 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 1 2 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 ?
