This insect wants the anal forceps, which is the main charac- 

 ter of the genus Psalidura, but it has the form and sculpture and 

 general appearance of the genus so marked, that it should clearly 

 not be separated from it, especially as it has less affinity for the 

 next 2'enus Talaurlnus.

This insect, like P. ahnormis, is a Psalidura in every respect, 

 excepting the absence of the anal forceps in the male. These 

 two species, in fact, seem to lead from. Psalidura to the next 

 genus, their anal formation being frequent enough in the genus 

 Talaurmns, while their appearance is undoubtedly that of 

 Psalidura.
