Belg. 1872, pp. xviii-xxiii. Koppen, in considering the enormous area over 
which the species hns been found, gives three distinct limits for its distribu- 
tion : — (1) countries in which it permanently breeds ; (2) those beyond these 
in which it continues for a few years and then disappears; (3) those to 
which its migrations are occasionally extended, but where it never breeds. 
De Selys-Longchamps (1. c. pp. xxiii & xxiv), in continuation of De Borre’s 
remarks, points out that two species are commonly confounded under P. mi~ 
graioriuSj viz. this and P. cmerascens, F. ; and he states that in Belgium the 
former is only of occasional occurrence, wliercas the latter appears every 
year in certain localities, and no doubt breeds in the kingdom. 
Extracts from a South Australian newspaper respecting the ravages caused 
by ‘‘locusts ” in that colony appear in P. E. Soc. 1872, pp. xii-xvii.
