of larvae and adults, and their classilicatiijn being- detailed. Two 

 new genera and a subgenus (iioin. [^racocc.) are deseribed, and 

 eight new species. 



Part 1\' deals with the Fipiiiiciilidac \ their habits, the form 

 of the larvae and pnparia, and the classification of the numerous 

 species. Thirty-two new species are described ; the full descrip- 

 tion of one species, however, is omitted and will be found in I't. 

 X. All belong to the genus Pipuncuhts, and half the whole num- 

 ber of species -were bred. 



In Part V, some predaceous enemies of leaf-hoppers are con- 

 sidered. The complete life-history of the earwig Clu'lisoclus 

 inoruK is given, and a detailed account of the lacewing-tiy. 

 Clirysopa micro pit ya, its eggs, larvae and pui)a case. Two re- 

 markable leaf-hopper-eating Syri)]iidae are described as new 

 species of the genus BaccJia. 



Part \M gives an account of the M>niaridae. their habits (the 

 life-historv of Paraiiagnis optabilis being detailed) and their 

 classification. Tn addition, some egg-parasites of the Procto- 

 trupoid family Platygasteridae arc dealt with. Parthenogenesis 

 is shown to be usual in some INIymarids. Twelve new species 

 and two new genera (one in each of the two families) are de- 

 scribed, all being bred. 



Tn Part \"IT a variety of i)redaceous enemies of leaf-hopi)ers 

 is considered, the life-history and habits of the Locustid Xiplii- 

 iliinii ivripcnuc, being ver\' fully given, as well as the variation 

 in length of the tegmina. The life-histories and habits of the 

 Coccinellidae, CalUncda tcsfudimiria, Coccinclla rcpanda. I ^crania 

 frcnafa and J\ strigiila (under the name ['. liiicola) are detailed; 

 also those of the Hemiptera Zclits pcrcgriiiiis. Rcdwi-iolus hlack-

Part A^III deals with Chalcids of the families Encyrtidae, 

 Eulophidae and Trichogrammidae. and contains remarks on 

 habits, classification and parthenogenesis. Thirteen new genera 

 and nineteen new species are described, all bred, some being- 

 direct, others secondary parasites. 



Part IX is devoted to leaf-hoppers themselves: their habits, 

 and what is known of their life-histories is referred t<i or de- 

 scribed. The life-history of the sugar-cane leaf-hopper is given 

 in detail, and the various stages are described. The varying 

 condition of the flight-organs of leaf-hoppers is discussed at 

 length. Their systematic position and classification is very fully 

 dealt with, a survey of previous svstems being given, and a criti-
