52 THE ENTOMOLOGIST. 
Diptera of West Cornwall. By C. W. Dats, F.E.S. 
About 400 species are enumerated in this list, which commences with 
the too familiar Pulea irritans and ends with a member of the Hippo- 
boscide, Melophagus ovinus. Reprinted from the ‘Transactions of the 
Penzance Natural History and Antiquarian Society,’ 1890-91. 
Catalogue Raisonné of Silk-producing Lepidoptera. By Atrrep WAILLY, 
Pp. 35, Svo. 
In his opening remarks the author refers to those species of exotic silk- 
worms which can be most successfully reared in the open air in Kurope ; 
he then refers to the various contagious diseases to which the larve are 
subject; and concludes by pointing out how silkworms can, for commercial 
purposes, be best reared in their native country. In the Catalogue itself 
the species of silk-producing Bombyces are considered. under the heading of 
the particular Continent to which they respectively belong. This little 
book should be useful to all who are interested in sericulture. 
An Elementary Manual of New Zealand Entomology. By G. V. Hupson, 
F.E.S. Demy 8vo, pp. 128, and 21 col. plates. London: West, 
Newman & Co. 1892. 
A popular introduction to the study of the Insect Fauna of New 
Zealand; the author’s chief purpose being to induce his readers to take an 
active interest in the investigation of insect life in the country of which he 
treats. With this object in view, remarks of an elementary character are 
made on classification, and the best methods of collecting insects con- 
sidered. Certain species in most of the tamilies of each Order are referred 
to, and the habits of the perfect insects and their earlier stages discussed 
in a manner that should arrest the attention of those for whose especial 
Instruction and guidance the work has been undertaken. No scientific 
descriptions are given, but the insects, and in most cases their respective 
larvee and pupe, are figured. The chromo plates by West, Newman & Co. 
are excelleut reproductions of the original drawings by the author, and these 
largely add to the general value of the book. To everyone interested in the 
Entomology of New Zealand we can heartily commend this useful book. 
Transactions of the City of London Entomological and Natural History 
Society. 1891. 8vo, pp. 38. Published by the Society, 33, Fins- 
bury Square, H.C. 
Under the above title, this Society has issued a reprint of the reports 
of its bi-monthly meetings previously published in the ‘ Record,’ &e. A 
figure of an interesting aberration of A. aglaia is given, but this also has 
been published before. ‘There is a paper on ‘The Genus Donacia,” 
by Mr. G. A. Lewcock. No information as to the present condition and 
financial position of the Society appears, but possibly it was not considered 
** the thing” to mix up such matters with the ‘ Transactions.’ We wish 
this modest little volume every success, and hope that it will be the means 
of attracting more workers to the Society from which it emanates. .
