not difficult, in fact, to recognize the direction that an editor’s 
labours would have to take should it ever be decided to produce a 
new edition of this book; his researches would have to be devoted 
chiefly to collecting the records of cases in which particular species 
had proved specially injurious, and the details of the application of 
new remedies, of which many, as may be seen from Miss Ormerod’s 
useful little book, have been proposed with varying success, often 
involving the use of materials comparatively unknown when Curtis 
wrote. This new information might easily be worked up into the 
form of appendices or supplementary notes without interfering 
seriously with the original text, and changes of nomenclature, of 
which there are many, could be indicated in a similar manner. 
Monograph of the British Aphides. By Grorer Bowpier Bucrton. 
Vol. IV. 8vo. London: Ray Society, 1883. 
In this fourth volume Mr. Buckton concludes his monograph of 
the British Aphides, and supplements the descriptive portion with 
some general remarks, which will serve to direct the attention of 
students to the very interesting questions connected with the history 
of that remarkable group of insects. . 
The species here described are the British members of the tribes 
Pemphiginz, Chermesine, and Rhizobiine ; they are treated in the 
same fashion as in the preceding volumes, and several of them are 
of special interest in connexion with M. Lichtenstein’s theory as to 
the reproduction of Aphides. The views of that entomologist, 
which appear to be gaining ground, are quoted by the author in 
several places, notably in connexion with the genus Phyllowera, 
under which we find the translation of an excellent summary of his 
opinions furnished by Lichtenstein himself to Mr. Buckton (p. 63), 
which will be of great service to English readers, 
As already stated, Mr. Buckton has appended to the systematic 
part of his work a discussion of various interesting questions con- 
nected with the natural history of Aphides in general, commencing 
with some remarks on the relation between Aphides and Ants—a 
subject upon which much has been written, often in a somewhat 
hyperbolical strain. Mr. Buckton apparently does not regard the 
extant evidence as sufficient to establish anything like a necessary 
relation between the Aphides and the Ants in whose nests they are 
sometimes found; and certainly those writers who maintain that 
certain ants obtain nearly the whole of their sustenance from plant- 
lice are manifestly in the wrong. At the same time the existence 
of this curious relationship between insects of such different types is 
proved by the testimony of so many good observers, that we cannot 
deny it some considerable importance in the economy of the ants. 
Mr. Buckton’s remarks are eminently suggestive. 
The most important section of his supplementary matter, how- 
ever, is that in which he deals with the reproduction of Aphides ; 
and in the preparation of this he appears not only to have carefully
