 ? ; of posterior femora, 16mm. g , 16mm. -18mm. ? ; of ovipositor,

Occurs in southern Italy and south-eastern Europe. 



8. Platycleis grisea, Fabricius. 



Of medium size ; grey, often varied with green when alive, with 

 dark and black spots ; elytra and wings perfectly developed, the 

 former with a row of black spots; wings hyaline; anal segment of the 

 male broadly excavate in the middle, the lobes toothed on the inner 

 side ; cerci of the male conical, with a tooth in the third apical part ; 

 all ventral segments of the female plain ; subgenital lamina of female 

 with narrow sulcus, roundly emarginate, the lobes very short and 

 round. Ovipositor curved up regularly from the base. Length of 

 body, 17mm. -22mm. $ and $; of pronotum, 5mm. -6mm. $ , 5-8mm.- 

 6-2mm. J : of elytra, 18mm. -26mm. 3 , 19mm.-28mm. $ ; of posterior 

 femora, 17mm.-21-5mm. $ , 19mm. -23mm. $ ; of ovipositor 9mm.- 

 10mm. 2 • 



This is the commonest, most familiar, and most widely distributed 

 species of the genus. In appearance, form and colour, it exactly 

 resembles the group of P. intermedia, and the males can hardly be 

 distinguished apart, but the female has the ventral segments all plain. 



It is common throughout Europe, chiefly among dry grass ; in 

 Britain it appears to be commonest on chalky soil, among rest-harrow, 

 Ononis arvensis. It occurs also in Sweden. It is common through- 

 out Belgium, France, Switzerland. In the south it occurs in Spain 

 from June to September, and throughout Italy. 



In Scandinavia it is recorded from Anneborg in Smaland, Soder- 

 koping and Ramshall in Gottland, in Oland, and in Seland, near 

 Tidsvilde. 



9. Platycleis incerta, Brunner. 



This species has the colour of P. grisea, but the form of ovipositor 

 of P. tesselata, which it also resembles in having short elytra, which 

 are unicolorous, and do not surpass the 3rd abdominal segment ; the 

 ventral segments of the female are all smooth. The male is not 

 known. Length of body, 16mm. $ ; of pronotum, 4-5mm. $ ; of 

 elytra, 4mm. $ ; of posterior femora, 16mm. ? ; of ovipositor, 6mm. $ . 



Based on a single female in Brunner's collection, received from a 

 dealer, and labelled as coming from Rhenish Prussia. 



10. Platycleis stricta, Zeller. 



Small ; greyish ; elytra longer than the body, narrow, with dark and 

 pale spots; ovipositor little incurved, twice as long as pronotum, pale, 

 dark at apex. Length of body, 13mm. -16mm. $ , 13mm. -17mm. $ ; 

 of pronotum, 3 - 5mm.-4mm. 3 , 4mm. $? ; of elytra, 14mm. -17mm. 

 3 and 2 ', of posterior femora, 16mm. -17mm. 3 , 16mm. -19mm. 2 ; 

 of ovipositor, 10mm.- 12mm. $ . 



This is the first of the second division of the genus ; it resembles 

 P. tesselata superficially, but the ovipositor is quite different, being 

 long, and regularly curved. 



It was discovered on the Appian Way, near Rome.
