REVIEW. 



Insects : Their Structure and Life. A primer of Entomology. 2nd 

 edition, revised. By C^eorge H. Carpenter, D.Sc. J. j\I. Dent 

 and Sons, Ltd. London and Toronto. 1924. 



We must congratulate Dr. Carpenter on the issue of a second edition 

 of his well known and very useful book. This edition is enriched by 

 four very beautiful colour-printed plates illustrating the protective 

 modifications of colour in caterpillars under the influence of their 

 surroundings (after Poulton) ; forms of British moths showing Mendelian 

 inheritance (after Bateson) ; oriental silk moths and their cocoons (after 

 Watipon) ; and mimetic forms of a South African butterfly, Papilio 

 dardanus, and the four species which the varieties of its female imitate. 



The chapter on the Evolution of Insects has been mainly rewritten 

 and some other parts of the book are " brought up to date," always a 

 difhcult and somewhat unsatisfactory labour. We note that the queen 

 wasp in Fig. 174 is still very unlike the species — Ve-^pa sylvestris — which 

 it purports to be. But no matter — and we hope this edition will serve 

 its purpose as well as the first edition appears to have done.

A PROPOSED NEW JOURNAL. 



The Belfast Naturalists' Field Club has under consideration a 

 proposal to establish under its auspices a monthly magazine of natural 

 history, archaeology and literature. Such a venture being beyond the 

 means of the Club it is at present seeking to ascertain the measure of 

 support likely to be received from outside sources, by way of guarantee 

 or annual subscription. 



It is proposed that the magazine should be not only a journal 

 of. scientific records, but to a large extent a popular magazine, with 

 comments, personal notes, reviews, etc., and thus made to appeal to 

 all interested in natural history, antiquities or literature. A special 

 feature, it is hoped, will be its helpful advice to those engaged in the 

 teaching profession throughout the country. 



Several offers of fmancial assistance have been received, though many 

 more are needed. The guarantee fund is unlimited, with a minimum 

 of half a guinea, and offers of support should be sent to either of the 

 undersigned. It is calculated that the proposed magazine would cost 

 £200 per annum to print less advertising space, while the promoters are 

 anxious that the annual subscription be not more than 6s. The editorial 

 staff will consist of specialists in the several departments under a Chief 

 Editor, and its work will be entirely voluntary.
