I. Introductory Remarks. 



During the last decade the Oollembola have attracted a con- 

 siderable amount of attention both from morphologists and 

 systematists. Collections of these primitive insects have been 

 studied from various regions of the world. Hitherto, however, 

 I am not awai'e that any species of the Order have been known 

 and recorded from the Indian Empire. The present paper is 

 intended as a small contribution towards a knowledge of the 

 Collembola of that extensive region. 



I am indebted to Dr. N. Annandale for handing over to me 

 for examination the specimens contained in the collections of the 

 Indian Museum, and to Mr. E. E. Green for forwarding me two 

 species from Ceylon. In addition to the species received from the 

 above two sources, I have myself collected a number of examples 

 in several parts of India, from Allahabad in the " plains " up to 

 an altitude exceeding 12,000 feet in the Himalayas. The area 

 thus worked over lies within two zoo-geographical regions. The 

 collecting, however, has only been done during casual intervals, 

 and generally when I was occupied in searching for other forms 

 of animal life. I wish to acknowledge the facilities for consulting 

 entomological literature that were afforded me by the libraries 

 attached to the Indian Museum, Calcutta, and the Agricultural 

 Research Institute, Pusa,. 



Altogether 571 specimens of Collembola have been examined 

 and from among these, 4 genera and 27 species are described as 

 new, and 3 species were already known.
