and therefore wingless, earwig, in which the forceps (cerci) are pro- 

 portionately much longer and simpler than they are in the imago. 

 It should be noticed also that cerci are present in many cases in 

 another old order — the Neuroptera. 



Yet another point in favour of this group of insects ! Those who 

 take it up will be practically free from the wearisome strife over 

 names — that incubus of modern entomology. There is, in fact, very 

 little controversy with regard to priority in the case of the British 

 Orthoptera. It may be that as it is not a show-order those who take 

 it up do so from the naturalist's point of view only — from the interest 

 attaching to the insects themselves, their habits and life-histories — 

 and so do not worry themselves about such unessentials as the dry 

 bones of nomenclature. 



We might divide the British Orthoptera into three groups accord- 

 ing to their status in our fauna : 



(i) Those considered to be indigenous. 



(2) Not indigenous, but naturalised, as shewn by their breeding 

 here 



(3) A large but uncertain number of casuals — interesting no doubt, 

 but whose names should not appear upon our lists-.

* These three insects occupy at present a somewhat precarious footing on 

 the list.
