 C.I.E. (now Agent to the Governor-General in Baluchistan) ; Colonel G. 

 Chevenix Trench, C.I.E., and Colonel C. A. Kemball, C.I.E., both of 

 the Political Department; Major (now Colonel) R. E. Roorne, Commandant 

 of the Z hob Levy Corps; and Captain E. H. S. James, of the Political 

 Department. My thanks are also due to the Raja of Chamba State 

 for the facilities kindly placed at my disposal during my tour there in 

 1909. To the many officers in the Civil Service through whose divisions 

 and districts I toured throughout the country my thanks are due for the 

 cordial assistance always afforded me. I would also wish to thank here 

 my old head clerk Babu A. T. Das, and my tour clerk Babu Nilumbar 

 Dut, to whom I feel I am greatly indebted. 



During the compilation of the work I have received valuable counsel 

 and advice from Dr. A. E. Shipley, F.R.S., Master, Christ's College, 

 Cambridge; from Mr. Guy A. K. Marshall, of the Entomological Research 

 Committee ; and Dr. R. Steuart MacDougall, Lecturer in Forest Zoology 

 at the University of Edinburgh, and a Member of the Entomological 

 Research Committee. Mr. Marshall has added to the obligations under 

 which he has laid me by undertaking a considerable amount of identifi- 

 cation work besides working out the Curculionidae and describing several 

 new species. 



In the Insect Department of the Natural History Museum, South 

 Kensington, I have received unstinted help. Mr. C. J. Gahan, Keeper 

 of the Department, identified the Cerambycidae ; Mr. Gilbert Arrow some 

 of the lamellicorns ; Mr. K. G. Blair described several new Tenebrionidae, 

 and Mr. R. Meade-Waldo dealt with the Hymenoptera. Mr. Claude 

 Morley kindly undertook the Ichneumonidae, describing new species. For 

 several years past my friend Mr. G. Lewis, F.L.S., has been good enough 

 to determine Histeridae for me. 



My sincere acknowledgments are also due to Monsieur P. Lesne, 

 of the Paris Museum, who named the Bostrvchidae, and to Monsieur G. 

 Severin, Conservator of the Brussels Museum of Natural History. In 

 Brussels Monsieur Severin undertook to get named a considerable portion 

 of the collections, and to have drawings prepared where required. 1 he 

 following gentlemen, to whom my grateful acknowledgments are dm-. 

 helped in this work: MM. Fleutiaux, F. Ohaus, H. Gebien, K. Gcstro. 

 A. Grouvelle, S. Schenkling, M. Maindron, A. d'Orchymont, M. Pic. 

 M. Burr, and C. Kerremans, who described a new buprestid. 



In connection with the work on the Scolytidae and Platypodidae, 

 two families which occupy considerably over a fourth ot the hook, my 

 intention had been to deal with the whol-j collection myself, 

 appointment as Head of the Department of Forestry at 1 idinbui ;.;li
