10 THE entomologist's RECORD. 



The Oriental region repeats this specialisation, but not quite so 

 markedly. It is especially rich in Fhilampelinae, and less so in 

 Ainbidicinae, which equally predominate in the ^Ethiopian region. 

 The Achernntiinae are more equally distributed. Nevertheless, we 

 cannot satisfy ourselves that any of the groups certainly originated 

 in any of the regions, though the case is certainly strong as regards 

 the Sesiinac in the Neotropical region.

 (Continued from Vol. xv., p. 319.) 

 1. FoRFicuLA AURicuLARiA, Linn. 

 Dark chestnut ; head red ; antennae 13-15-segmentate ; pronotum 

 dark, sides paler ; elytra testaceous, with posterior border straight ; 

 wings well-developed ; feet testaceous ; forceps reddish, black at tips, 

 extremely variable in length ; in the ^ , dilated and flattened and denticu- 

 lated on inner margin at base, with a sharp tooth at end of denticula- 

 tions, then suddenly slender, incurved gently into an oval or circle, 

 according to the variable length of this organ ; in the $ , the branches 

 are straight, unarmed, contiguous. Length of body, 10mm. -14mm., 

 S , 2 ', oi forceps, 4-9mm. 3 , 3-5mm. 2 • 



The common earwig is abundant throughout Europe ; it occurs 

 also in North Africa, Madeira, Asia Minor, and North America. 



FoRFicuLA siLANA, A. Costa { — tartjionii, Brunner). 



Distinguished from F. auricidaria only by the absence of wings 

 and rounded hinder border of elytra ; the sides of the abdomen are 

 more parallel. Length of body, 11mm. -17mm., J , $ ; of forceps, 

 4-6mm. 3 , 3-4mm. ? . 



Recorded from Sila Grande in Calabria. 



FoRFlCULA APENNINA, A. Costa. 



Closely resembles Apteryr/ida media, but larger and stouter ; 

 branches of forceps of g broadened slightly at base, in form of a 

 triangular plate. Length of body, 13mm. -20mm., <? , 9 ; of forceps, 

 6-8mm. <? , 4-4mm. $ . 



Recorded from Calabria and the Abruzzi. 



FoRFicuLA PUBESCENS, Gene. 



Small and pale ; wings absent ; antennic 12-segmentate ; forceps 

 of (? contiguous at base, then almost contiguous down to the tooth ; 

 this dilated part occupies two-thirds of length of forceps ; beyond tooth, 

 branches simple, bent inwards ; in ? simple, straight. Length of 

 body, 6-7mm. <? , 5 ; of forceps, 3-4mm. ^ , 2mm. $ . 



This is a purely meridional species ; it is found on plants and 

 reeds in moist places ; adult in summer and autumn. In France, it is 

 common in the extreme south ; m Italy, it has been taken at Pegli, 

 and at Messina in the spring. It is found also in Corsica and Sardinia, 

 and the lialaniric Islands, and in Spain, where it is recorded from 

 Barcelona and Granada. 



FoRFICULA LESNEI, Finot. 



Resembles F. puhescens, but diflers in the shape of the forceps of
