128 THE entomologist's record. 



Calvados, Lamothe, La Teste-de-Buch, Cazan, Episy, Pouliguean, lie 

 de Noirmoutiers, Nantes, Granville, Fontainebleau, Meudon, Wimereux. 

 In Spain it appears to be rare, being only recorded from Ferrol, 

 Chiclana. In Austria it is found at Modling, the Prater, Oberweiden, 

 and Briick. 



It chiefly frequents dry sandy places, but is also found in swampy 

 fields. 



4. Chorthippus dorsatus, Zetterstedt. 



Closely resembles the preceding, but is of a stouter build, more 

 generally green in colour, and diHers in the venation of the elytra. 

 Length of body, limm.-lSmm. J , 19mm. -26mm. ? ; of pronotum, 

 3mm. -4mm. J , 4mm. -5mm, $ ; of elytra, 10mm. -14mm. $ , 10mm.- 

 21mm. J . 



Common in northern and central Europe; in France it is common, 

 and recorded from numerous localities ; it is rare in the south, recorded 

 from Tarbes and the Riviera. It is not known in Britain, but recorded 

 in Belgium from Barraque, Michel, Genck, and Laeken. In Scandinavia 

 it is noted from Skane, Smaland, Bohuslan, W. Gottland, Stockholm, 

 and Gottland, Esperod, Abusa, Fogelsang, ufvedskloster, Lund, and 

 Finjasjon. In Spam it is recorded only from Collsacabra in northern 

 Catalonia. 



5. Chorthippus parallelus, Zetterstedt. 



Green ; knees black ; antennae long ; wings abortive ; elytra 

 extend to apex of abdomen in ^ , abbreviated and lanceolate in $ . 

 Length of body, 14mm. -IGmm. ^ , 18mm. -21mm. $ ; of pronotum, 

 3mm. (J , 3-8mm.-4mm. J ; of elytra, 8mm. -14mm. S' , 6mm. -16mm. 



?. 



The dimensions show that the organs of flight are occasionally 

 fully developed, but this variety is quite rare. 



It is common throughout Europe, chiefly in damp fields. It occurs 

 in Lapland and Norway, Sweden and Denmark. In Britain it is 

 abundant in nearly all fields, and in France also. It is abundant in 

 Belgium, and common throughout Spain and Portugal. 



A very large and pale coloured variety is recorded by Brunner from 

 Malaga, which attains 20mm. in the 3 , and 30mm. in the 2 • 



6. Chorthippus longicornis, Latreille. 



Very closely allied to the preceding, and doubtless often confused 

 with it ; distinguished by the somewhat longer antenna-, by the trans- 

 verse sulcus being in the middle of the pronotum, by the long valves 

 of the ovipositor, which are very noticeable ; axillary vein of the S 

 elytra is confluent in the middle with the anal vein. Length of body, 

 14mm. -15mm. S' , 17mm. -21mm. 5 ; of pronotum, 3mm. <? , 

 3-5mm.-4mm. $ ; of elytra, 8-5mm.-9mm. ^ , 7mm. -8mm. $ . 



The organs of flight are generally better developed in this than in 

 the last species, and it is more likely to be confused with the fully- 

 winged form of the latter. 



It is common in swampy fields in central France ; Fontainebleau, 

 ij^pisy, Malesherbes, Nemours, Loiret, Lamothe, Arcachon, Fontev- 

 rault, Montreuil, Amelie-les-Baines, Lraguignan, Essonne, St. Cyr. 

 It is recorded from Laeken near Brussels. It is not yet known in 

 Britain.
