of the Brachycera except the Empidae, Doli- 

 chopodidffi, Lonchopteridffi and Phoridse. He 

 gives the characters of all the subfamilies and 

 important European genera, whether occurring 

 in England or not. His arrangement of the 

 brachycerous Diptera is based on that of Osten 

 Sacken, but with several important modifica- 

 tions. It is as follows : Eremochseta (Strato- 

 myidse, Leptidse, Tabanidse, Nemestrinidae and 

 Cyrtidse) ; Tromoptera (Bombylidse and There- 

 vidse) ; Dermatina (Scenopinidse and Myda- 

 idae) Emegopoda (Apioceridse and Asilidse) ; 

 Microphona (Empidae and Dolichopodidse) ; 

 Acroptera (Lonchopteridas), and Hypocera 

 (Phoridse). He puts Xylomyia in the Strati- 

 omyidse and Xylophagus in the Leptidae. In 

 the Asilinse he uses the various genera pro- 

 posed, but, recognizing the difficulty of their 

 identification, he also gives a table of the 

 British species based on superficial characters. 

 An important feature is an illustrated article 

 on the larvae of the Brachycera, and of the 

 Syrphidse, Platypezidffl and Pipunculidffi by 

 David Sharp, partly translated from Brauer. 

 In the back is a list of the species common to 

 Europe and North America, and as a supple- 

 ment a catalogue of the Palsearctic Diptera 

 Brachycera (except Dolichopodidse and Em- 

 pidae). 



Dr. L. G. Neumann has issued a useful 

 little book on the parasites and diseases of 

 domestic birds." It contains much interesting 

 matter on the insects and mites that attack 

 poultry and pigeons, arranged according to 

 the parts affected. There is a short descrip- 

 tion of each parasite, the nature and appear- 

 ance of the injury it causes, and the remedies 

 that may be used to combat it. Most of the 

 figures of these forms are original and ac- 

 curate. 



Drs. J. W. W. Stephens and S. E. Chris- 

 tophers have prepared a book' that wiU be of 

 much help and interest to the many who are 

 now concerned in the study of medical ento- 

 mology. The entomological part is in two

chapters on ticks, one on tsetse flies, etc., and 

 fifteen chapters on mosquitoes. In the latter 

 are directions for collecting, rearing, dissec- 

 tion, etc. There are chapters on How to 

 Prepare a Blood Film, How to Detect the 

 Malaria Parasite, How to Make a Malarial 

 Survey, on the Life-history of the Malarial 

 Parasite, on Piroplasma and on Trypanosoma 

 and the diseases produced by them. 



Dk. J. Kennel has begun the issuance of a 

 large work on the European Tortricid moths.' 

 Part I. is published, and contains an account 

 of the structure, habits, life-history and varia- 

 bility of the leaf-rollers, and a table for the 

 determination of the 55 genera. There is a 

 long account of the relationships of the genera, 

 and the phylogeny of the groups, illustrated 

 by a plate of wing venation. The systematic 

 part treats of the 43 species of Acalla, while 

 the beautiful plates figure the species of this 

 genus and those of Philedone, Epagoge and 

 Cacoecia. There are to be 24 plates in the 

 entire work, which is partially supported by a 

 grant from the Elizabeth Thompson Science 

 Fund. 



Mr. E. p. Van Duzee has published the 

 results of a recent collecting trip to Florida.' 

 Over 330 species were taken, 28 of which are 

 described as new. He finds that the hemip- 

 terous fauna of Florida is made up of four 

 elements: (1) the Carolinian, which spread 

 southward from the Georgia mountains; (2) 

 the West Indian, which has extended over the 

 tip of Florida and up each coast; (3) a few 

 forms from Texas and Mexico; and (4) the 

 endemic species, which are very numerous, and 

 largely local adaptations of the Carolinian 

 migrants.
