SYNOPSIS OF THE ORTHOPTERA OF WESTERN EUROPE. 



319 



is easily recognised by its small size, uniform brown colour, and by 

 the small spine on the pygidium of the male. 



Labia minor, Linn. 

 Length of body, 4-5mm., <? , $ ; of forceps, lmm,-2-5mm., ^ , 2 - 

 More or less common throughout central Europe, including 

 England, and the whole of France. It probably occurs throughout 

 Spain, but has only been recorded from a few isolated localities. It 

 flies on warm summer evenings over flowers, dungheaps, etc., often in 

 company with Staphylinids. It extends as far north as Scania in 

 Sweden. De Selys notes that in Belgium it is somewhat local. 



Genus 4 : Forficula, Linn. 

 This genus includes a large number of exotic forms characterised 

 by the forceps of the male, which are strongly dilated, flattened, and 

 depressed near the base, sometimes for a considerable part of their 

 length. 



Table of Species. 

 1. Wings present (sometimes not very prominent). 

 2. Elytra spotted. 



3. Dilated part of forceps and pygidium short.

4. Dilated part of forceps not exceeding one- 

 third of entire length of forceps . . 

 4.4. Dilated part of forceps reaching half 

 entire length 

 2.2. Dilated part of forceps short. 



3. Tooth at end of dilated part of forceps. . 

 3.3. No tooth at end of dilated part of forceps 



Alternative Table of Species (based on Brunner's arrangement, 

 where the elytra of F\ nificollu, Fabr., are given as unicolorous, as the 

 spot is sometimes indistinct). 



1. Dilated part of forceps having a tooth, sharp or blunt, at 

 the end. 

 2. Branches of forceps contiguous at base only, separated 

 at the tooth, which is sharp. 

 3. Hinder border of elytra straight ; wings 



present . . 

 8.8. Hinder border of elytra round. Wings 

 wanting . . 

 2.2. Branches of forceps contiguous down to the tooth, 

 which is blunt. 

 3. Dilated part of forceps very long, the apices 



almost or quite meeting 

 3.3. Dilated part of forceps shorter, apices not 

 meeting 

 1.1. No tooth at end of dilated part of forceps. 

 2. Dilated part of forceps long. 

 3. Wings absent 

 8.3. Wings present. 



4. Elytra with a big spot ; wings prominent. . 

 4.4. Elytra with indistinct spot ; wings 

 developed, but hardly prominent 

 2.2. Dilated part of forceps short . .
