Through the courtesy of Dr. Nelson Annandale, Director, Zoo- 

 logical Surve}' of India, I have been entrusted with the few speci- 

 mens of spring-tails collected by Mr. S. W. Kemp on the Abor 

 Expedition, and with some other insects of the same order from 

 Lower Burma, in the Indian Museum collections. The res'ilt of 

 work on these Collembola is now given. Seven species are enumer- 

 ated : six of these are described as new, one (from Rotung in 

 the Abor Hills) being made the type of an interesting new genus 

 resembling Cyphoderiis, but showing certain primitive and annec- 

 tant characters. The remaining species is a Cyphoderus already 

 described in Imms' paper (1912) on Collembola from India, Burma 

 and Ceylon, to which the present brief contribution may be re- 

 garded as supplementary. Excepting the Rotung specimen just 

 mentioned, all the spring-tails now described belong to well-known 

 genera with a wide distribution, one being referable to the family 

 Poduridae and the rest to the Entomobryidae. I have taken ad- 

 vantage of the material at my disposal to give some details of the 

 jaws of Protanura and Paronela, as the structure of these appen- 

 dages in Collembola is of high interest to students of insect mor- 

 phology. 



PODURIDAE. 



NEANURINAE. 



All the Poduridae in the collection belong to a single species 

 referable to the sub- family Neanurinae, whose members are easil}'- 

 recognized as a rule by their spine-bearing tubercles, 



Protanura, Borner, 1906. 



This genus was established by Borner (1906, pp. 167-9) for 

 those Neanurinae in which the mandibles and maxillae have toothed 

 apices, whereas in Neanura [Achorutes as Borner calls it) ' the max- 

 illae are simple, terminating in a single sharp point. 



i I have already (1916, p. 29) given reasons for refusing to follow Borner in 

 this highly inconvenient chans^e of nomenclature.
