Geographical Distribution. —'l'his species is widely distributed 
over the Western Palearctic region, but its full distribution is probably 
uncertain, and its true range may be further concealed beneath other 
specific names, whose value has not yet been authoritatively examined. 
cr ystallina i is found quite throughout the British Isles, and there are 
only a few isolated districts for which its occurrence has not been verified.
