I have pleasure in associating this interesting little spring-tail 

 with the name of its discoverer Mr. Stanley W. Kemp. 



It is to be hoped that further specimens will be found so that 

 a fuller knowledge of the structure may be obtained. The obvious 

 features are, however, so striking that I have ventured without 

 scruple to establish the new genus and species on a single insect.
