greatly increased by the careful way in which the references are given 

 when quotations are made. 



The plates as a whole are excellent, but in some instances the 

 printing of the pterostigma is a little faulty, and in plate xx. the 

 figures of Calopteryx are not sufficiently robust. Some of the figures 

 of anal appendages, magnified, are so beautifully done as to make us 

 wish that similar figures of the anal appendages of all the species 

 were given. 



Should a new edition, or a supplement, be issued, it would be 

 useful if a few plates were inserted showing the immature condition of 

 the commoner Agrioninee, which, though fully described in the book, 

 are not figured, and are too often a stumbling-block to beginners. 

 Plates also of a few allied species not as yet discovered in the British 

 Isles, but from their distribution not unlikely to occur here — such as 

 Somatochlora alpestris, ^-Esckna affi,nis, Agrion hastulatuiii , and a few 

 others — would be useful, and might serve to enrich our fauna by enabling 

 species hitherto undetected to be recognized, in which case our author's 

 gloomy forecast of a decrease in our list would be falsified. 



The remaining chapters deal with the reputed species ; breeding 

 from the nymph ; preparing for the cabinet ; addenda ; reference to 

 the full titles of books quoted ; and a very carefully compiled index. 



The book should certainly be in the library of everyone interested 

 in the group, and Mr. Lucas is to be congratulated on having so 

 successfully demonstrated the error of the often expressed idea that a 

 book on British dragonflies could be nothing more than a translation 

 of extracts from De Selys Longchamps' ' Revue des Odonates.'

V. BiANCHi. Enumeratio openim opusculoriimque ad faunam. Hemi- 



pterorum tieteropteroruiii Imperii Rossici pertinentem 1798-1897. 



(Ann. Mus. Zool. Petersb. 1898 [publ. 1899] , pp. 289-323.) 



The author has rendered good service to his colleagues by the 



preparation of this Catalogue, which enumerates the works treating, 



during the periods included, of the Heteroptera of the Russian Empire. 



Nearly sixty authors (and about three hundred and fifty works) are 



recorded, and further help is afforded by a faunistic summary, nineteen 



divisions being adopted ; neighbouring countries (as, for example, 



Galicia, the Danubian Principalities, and Corea) are also included — 



placed under smaller headings. It is to be hoped that Dr. Bianchi 



will prepare a similar catalogue of the works dealing with Homoptera.

General Index to Miss Ormerod's Reports on Injurious Insects, 1877-1898. 



By R. Newstead. With Preface by the Author of the Reports. 



8vo, pp. 58. London : Simpkin, Marshall & Co. 1899. 

 Tms comprehensive Index will considerably enhance the value of 

 the series of Annual Reports presented to the public by Miss Ormerod 

 during the past twenty-two years. In addition to the index to general 

 subjects, there are also a Plant Index, an Animal Index, and an Index 

 to Unclassified Hosts ; these further facilitate reference to the various 

 Reports.
