IV PREFACE. 



which he is one of the principal living authorities. The 

 present volume is occupied bv an account of the first three 

 families of the suborder Heteroptera. It is hoped that 

 future volumes "svill contain descriptions of the remaining 

 families, both of Heteroptera and Homoptera, of which the 

 Indian forms are sufficiently known to enable an account 

 of them to be compiled. 



Other volumes on Indian Invertebrata are in preparation, 

 and two are so far advanced that their early publication may 

 be expected. These two are a volume on Ants by Colonel C. 

 T. Bingham, and another on Longicorn Coleoptera by 

 Mr. C. J. Gahan. A volume of Land-Mollusca is also in 

 hand, and arrangements are being made for further additions 

 to the general series.
