already mentioned, while P. migratorius is an eastern species rarely 

 extending even to France, P. dauicus is more western in its range and 

 breeds in the south of France. 



(Edipoda cserulescens Linn, occurs as a casual occasionally ; it is 

 resident in the Channel Islands. Its wings pale blue with a black 

 band make it a conspicuous insect, when those organs are spread. 



Acridium aegyptium Linn, has occurred casually a considerable number 

 of times, having been introduced apparently with fruit or vegetables. 

 It is a south European species, the nearest breeding place to us being 

 the south of France. It is a very large dark greyish insect with base 

 of wings smoky and part of hind legs purplish. The nymphs may be 

 yellow or green. 



Schistocerca peregrina Oliv. (= tartar ica Linn.). In 1869 this migrant 

 arrived in the British Isles in considerable numbers, reaching at least 

 as far north as Burtoii-on-Trent. There is 110 record of its occurrence 

 since that date. This is the large locust light reddish in colour, with 

 paler spots and markings which does so much damage in Algeria. 



(Podisma pedestre Linn. (= Pezotettix pedester) has got into our older 

 lists through a mistake for Chorthippus pardllelus. Its elytra are 

 rudimentary and the hind tibia? bright blue.) 



(Psophus stridulus Linn, was given as British in Stewart's 'Elements 

 of Nat. Hist/ 1805, ii, p. 95, but no doubt through a mistake. It is 

 a rather large handsome insect, having vermilion wings tipped with 

 black.)
