INTEODUC'TION. 



inent in Burma, and to Mr. G. Kogers, late Deputy Conservator 

 of Forests at Darjiling. All these gentlemen were good enough 

 to procure ants for me, and my collection was thereby enriched by 

 many species 1 should myself not have succeeded in capturing. 

 To Mr. F. MoUer of Tukvar, near Darjiling, I owe a very large col- 

 lection of Sikhim ants ; and 1 have to aclcnowledge with thanks 

 the receipt of collections sent to me from time to time by Mr. E. 

 E. Green and Mr. O. AVickwar froni Ceylon. My most grateful 

 acknowledgments are, however, due to Mr. li. C. Wroughton, 

 Inspector General of Forests to the Government of India, and 

 my friend Mr. G. A. James Rothney, who in the most generous 

 manner placed at my disposal their rich collections of Indian ants. 

 1 have to thank Dr. Forel for the loan and gift of specimens, 

 many of them single types, and for his unfailing kindness and 

 courtesy in examining and identifying species for me. Dr. Forel's 

 papers on Indian ants, published chiefly in the ' Journal ' of the 

 Bombay Natural History Society, have been of the greatest as- 

 sistance to me, and I gratefully own that but for the publication 

 of those papers, the labour of compiling the present work would 

 have been far greater than it has been. 



I am under great obligations for the loan or gift of specimens 

 to Dr. R. Gestro of the Museo Civico, Genoa ; to Mons. E. Andre 

 of Gray, Haute-Saone, France; and to Professor Emery of 

 Bologna. Also to the Authorities of tlie British Museum for 

 free access to the collections at the Museum of Xatural History, 

 South Kensington. 



The illustrations for this work have required great accuracy 

 and care, and have been efhciently executed by the artist, 

 Mr. H. Knight. 



The systematic position of the Chrijsidida' is in my opinion 

 with theAculeata, and the latter portion of this volume deals with 

 the forms so far recorded from within our limits. I am greatly 

 indebted to Major C. Nurse, of the Indian Army, for the kind gift 

 and loan of many specimens. 



XoTE. — Under 'Tetrantorium, p. 175, the genus Bhoptromyrnux 

 is wrongly ascribed to Forel. The correct reference is : — 



Pihoptromyrmex, Mai/r, Ann. Hofmns. Wien, xvi (1901), p. 18.
