This genus is very distinct from any of the other genera of 
European Fieridte, being particularly so in the length of the abdo- 
men and in the extremely contracted discoidal cells. Its position, 
zoologically, is between the neotropical genus Leptalis and the 
genus Fontia, which is distributed over the intertropical regions 
of the Old World. 
The genus Leiicophasia is confined exclusively to Europe and 
North Asia, as far as the Amur. 
There are but two species, and one of these, Leucopliasia 
Sinapis, is not an uncommon British insect.
