ing and colouring, but still they will usually enable the user easily to 

 identify the plants figured. Complaint is made in the preface that the 

 author cannot notice "every species or even every genus of British 

 plants," yet space is wasted on some common plants like the cowslip, 

 and quite a number of non-British species are introduced, which, 

 besides making tlie title incorrect, gives one the impression (erroneous 

 no doubt), that the text was written to suit the plates.

The editor is to be congratulated on this production. The plates 

 are of the very first order. We look forward to some entomological 

 articles in future numbers.

Illustrations of British Blood-sucking Flies. With Notes by Ernest 

 Edward Austen, Assistant, Department of Zoology, British 

 Museum. Pp. 74, with 34 coloured plates. Natural History 

 Museum, South Kensington. 1906. 



Of the blood-sucking flies known as midges, gnats, horse-flies, 

 clegs, brimps, &c., most residents in the country, or visitors thereto, 

 will have at some time had more or less unpleasant experience. To 

 some persons the hum of Tabanus bovinus is more disconcerting than 

 the challenge of an angry bull ; such people have had experience 

 of the insect as a rural phlebotomist, and dread a repetition of the 

 operation. The silent-winged and ubiquitous Hamatopota pluvialis is 

 the fly which most frequently draws blood from the entomologist, but 

 the latter is also well acquainted with the bump-raising powers of 

 British species of Anopheles, Culex, &c., which Mr. Austen, in the 

 volume before us, states "are as much entitled to be called mosquitoes 

 as are tropical species belonging to the same genera." 



It is estimated that there are some seventy-four blood-sucking 

 flies in Britain, and enlarged portraits of the most important of these
