PREFACE. 



This the fourth volume of the Rhynchota in the ' Fauna 

 of British India' series deals with the Membracidse, Cer- 

 copidae, and Jassidse, the last a most obscure family of 

 Homoptera, and the Appendix (which has been commenced) 

 includes such species of the Pentatomidae,, Coreidse, and 

 Bervtidse as have been added to the Indian Fauna since 

 the publication in 1902 of Vol. I. of the Rhynchota. 



The arrangement and classification of the Indian Jassidse 

 has been a most arduous task, as so little pioneer work had 

 been done heretofore in this obscure group. It is hoped, 

 however, that the arrangement adopted, though it may here- 

 after be subjected to revision, will fulfil the primary object 

 to which all the volumes of the 'Fauna of British India' 

 series are directed, viz. that of enabling students of Natural 

 History in India to recognize and identify the forms of 

 animal life they meet with iu the course of their collecting.
