SYNOPSIS OF THE ORTHOPTERA OF WESTERN EUROPE. 139 



3.3 Ovipositor curved up at an angle at the base, 

 but little longer than the pronotum. 

 4. Subgenital lamina ? long and triangular, 



arched, slightly excised at apex . . . . 18. bicolor, Phil. 



4.4. Subgenital lamina with pointed lobes. 

 5. Cerci <? longer than subgenital lamina 



with tooth in third or fourth apical part 19. roeselii, Hagenb. 

 5.5. Cerci <? shorter than subgenital lamina 



ending in a fine tooth 20. marmorata, Fieb. 



2.2. Lobes of subgenital lamina ? notably long 

 and narrow (Pyrenean species). 

 3. Side flaps of pronotum darker than the disc ; 

 lobes of subgenital lamina ? pointed 



upwards 21. marqueti, Saulcy. 



3.3. Side flaps of pronotum paler than disc ; 

 lobes of subgenital lamina not pointed 

 upwards 22. buyssoni, Saulcy. 



1. Platycleis intermedia, Serville. 



Large; dark greyish ; elytra with row of black spots ; face pale; 

 the 7th ventral segment of the female has two complete transverse ridges; 

 the 6th segment is plain ; the subgenital lamina of the female with 

 a deep and narrow sulcus, and rounded lobes ; the ovipositor is dark 

 reddish, with a pale base, it is curved upwards from the base, and is 

 not one-and-a-half times as long as the pronotum. Length of body, 

 21mm. $ , 25mm. 2 ; of pronotum, 7mm. $ and ? ; of elytra, 26mm. 

 $ , 30mm. 2 ; of posterior femora, 23mm. 3 , 24mm. 2 ; of ovipositor, 

 9*0mm. 2 . 



This is a Mediterranean species ; in France it occurs only in the 

 south, at Montpellier, Chateau-Gomberg, Hyeres, in all Languedoc, at 

 Cannes, Frejus, Bagnols, Draguignan. Azam records a variety, which 

 he named sylvestris, from Bagnols, with the 6th ventral segment of 

 the female gibbous, and the 7th as in the type, but with the edges 

 more pronounced. In Spain it occurs probably throughout the 

 peninsula, certainly in the southern half, from July to December ; 

 also in Italy and Sicily. 



The male is hardly distinguishable from that of the very common 

 and widely distributed Platycleis grisea, which see. 



2. Platycleis sabulosa, Azam. 



In this species, the 6th abdominal ventral segment of the female 

 is plain, but the 7th has a transverse edge at the sides, but obsolete in 

 the middle, near the hinder third of the segment, and a second com- 

 pressed edge near the hinder border; the subgenital lamina has a narrow 

 furrow, as in P. intermedia. Length of body, 23mm. -26mm. 2 ; of 

 pronotum, 5-5mm.-6mm. 2 ; of elytra, 29mm. -33mm. 2 ', of posterior 

 femora, 22mm. -24mm. 2 \ of ovipositor, 11mm. -12mm. 2 • 



Found on sand, near Frejus, in September. 



3. Platycleis laticauda, Brunner. 

 Resembles P. intermedia in colour and form, but the 7th ventral 

 segment of the female is raised into a gibbous tubercle, and the 6th 

 also, but less elevated ; the subgenital lamina of the female is loss deeply 

 sulcate, and the lobes are rounded. Length of body, 22mm. $ , 25mm. 

 2 ; of pronotum, 7mm. <? , 7'8mm. 2 ; of elytra, 28mm. $ , 34mm. 

 2 ; of posterior femora, 24mm. $ , 34mm. 2 \ of ovipositor, 10mm. 2 •
