CONCLUSIONS. 
The evidence adduced in this paper points to the imperative necessity for 
the employment of more scientific method in the description and differentiation 
of species of Anoplura. It is shown that a leading authority on the group has 
blundered greatly in dealing with Pediculus, and this may be taken as a fair 
example (compare Haematopinus, etc.) of the manner in which many purported 
species, sub-species and varieties of Siphunculata are being foisted into the 
literature by that author. Surely it is time to call a halt to this unwarranted 
process of burdening science with useless specific and other names that are 
destined in many cases to fall into synonymy.
