SYNOPSIS OF THE ORTHOPTERA OF WESTERN EUROPE. 127 



3.3. Organs of flight abbreviated in ? ; elytra 



well developed in s , lobiform in ? ; wings 



rudimentary. 



4. Typical sulcus of pronotum nearer to hinder 



border ; valves of ovipositor short ; axillary 



vein of elytra d not confluent with middle 



of anal vein . . . . . . . . . . 5. parallblus, Zett. 



4.4. Typical sulcus of pronotum in middle ; 

 valves of ovipositor noticeably longer 

 than in preceding species : axillary vein 

 <? confluent with middle of anal vein . . 6. longicornis, Latr. 



1. Chorthippus jucundus, Fischer. 



Easy to recognise by its uniform green colour, with red hind tibisB, 

 and large size ; it hardly appears to belong to this genus. Length of 

 body, 24mm. <? , 31mm. $ ; of pronotum, 5mm. <? , 7mm. ? ; of 

 elytra, 20mm. c? , 26mm. $ . 



A southern species ; in France it is rare ; Montpellier, Serres, 

 Montelimar, Drome, Saint Angulf, Ponds of Villepey, Var. In Spain, 

 common in high grass and herbage near rivers throughout the country, 

 especially the south and centre. It probably occurs throughout 

 Portugal, and is recorded from Serra de Estrella and Panacova. 



2. CnoRTmppus pulvinatus, Fischer de Waldheim [ = declivis, 



Brisout). 



Extremely variable in colour ; length of elytra and wings exceed- 

 ingly variable ; they are better developed as a rule in southern than in 

 central Europe. It may be known from its allies by the large head of 

 9 , the straw-yellowish colour, with darker stripes, which begin from 

 the eye and run down the sides of the pronotum down the elytra ; the 

 third radial vein of elytra is unforked in both sexes ; the long sub- 

 genital plate of the ^ is also characteristic. Length of body 15mm.- 

 19mm. (? , 19mm. -25mm. ? ; of pronotum, 2-8mm.-8-4mm. 3 , 

 8mm. -5mm. J ; of elytra, 8imn-18-5mm. <?, 9mm. -16mm. J. 



In France, commonest in the south and central, recorded as far 

 north as Fontainebleau, and very many localities in the central and 

 south ; it is adult from July to December throughout Spain and 

 Portugal ; in Switzerland, at Geneva, and probably elsewhere also ; 

 in Austria, and in Italy, common in the north m August and 

 September. It is also doubtfully recorded from Jersey. 



Azam records a var. i/racilis of slenderer build and greyish-red 

 colour from Clermont-Ferrand, France. 



8. Chorthippus elegans, Charpentier. 



Greyish-testaceous, or green ; allied to C. dorsatus, but of 

 slenderer build ; differs as shown in the table ; the most important 

 point is the venation of the elytra. Length of body, 13mm. S » 

 18mm. 5 ; of pronotum, 2-5mm. ^ , 8-8mm. $ ; of elytra, 10mm. 

 (? , 18mm. ? . 



Locally distributed in Central Europe. In Sweden, recorded from 

 Oresund near Lomma, Esperod, Osterjon, Uddevalla, and in Denmark 

 from Nordsjon ; in England, from Deal, the New Forest, Freshwater, 

 the Cambridgeshire Fens ; in Belgium, from Blankenberghe, Ostend, 

 Wienport, Panna, Campine, Diepenbaeck, and Arlon ; from Germany, 

 at Berlin; in France, at numerous localities, though nowhere common, 

 Paris, Saint Questin, Lartoire, Bareges, Toulouse, AUier, Le Blanc,
