14. CICADIXEN (Hemiptera-Homoptera) VON MITTEL-EUROPA von Dr. 

 L. Melichar. 8vo., Berlin, Felix L. Dames, 1896. Price 20 Marks. This is 

 a volume of 364 pages and 12 well-executed plates. The external anat- 

 omy and biology are discussed and directions for collecting and preser- 

 ving given, as well as the literature and a historical review of the subject. 

 Geographically, the work includes Austro-Hungary, the German Empire 

 and Switzerland. Fieber's division of the Homoptera into eight families 

 is accepted by the author, and the most of those families erected by J. 

 Edwards stand as subfamilies only. Each genus and species is fully de- 

 scribed and figured in detail, and keys to the genera and species are not 

 wanting. The synonymy is apparently also very complete. The work 

 is important to Hemipterology, and students of Homoptera will no doubt 

 find it indispensible. F.
