This is a somewhat uncommon Pahoarcti(; species, first described 

 by Gravenhorst from Piedmont in 1829; and in Britain apparently 

 confined to its southern half. It has not yet been bred, but is 

 confined to marshy districts, where it is on the wing in June. It 

 has not hitherto been recorded from beyond tlie confines of 

 Central Europe, but I have seen in the Pusa collection a dozen 

 specimens of both sexes from Bengal, taken in February and 

 March on grass, lucerne, cauliflo\^ er, and mustard, and in wheat- 

 tields, for the most part at Pusa.
