MOTHS OF THE SUBFAMILY BISTONINAE. —

II].—_THE GENUS AMORPHOGYNIA (WARREN). 
Amorphogynia necessaria (Z.) Distribution.—Asia Minor 
from Smyrna to Armenia. 
Amorphogymia inversaria (Rebel.) Distribution.—Eastern 
Rumelia. 
This genus is a direct derivative of Lycia and there is but 
little to separate the two genera except the semiapterous 
females of the present group. This being so, it must have 
originated in Asia Minor subsequent to the advent of Lycia 
hivtaria. Even in Asia Minor it has been able to occupy only 
a small area although it had reached Europe before the geol- 
ogical changes resulting in the union of the Black Sea and the 
Mediterranean had occurred. The formation of the Bosphorus, 
Sea of Marmora and the Dardanelles, therefore, divided the 
then species into two branches which have diverged so much 
owing to geographical isolation that, whilst it is dubious 
whether the divergence is of specific value, it is still certainly 
of varietal importance. The exact status of the two forms 
cannot be determined until the male of A. inversaria is discov- 
ered. 
IV.—THE GENUS POECILOPSIS (HARRISON) 
Poecilopsis pomonaria (Hb.) Distribution:—North and 
Central Europe as far west as Paris, Piedmont, Uralsk. Absent 
from Holland, Belgium, the British Islands, almost the whole 
of France, Spain, Italy and the Balkan Peninsula. 
Poecilopsis 1sabellae (Harrison). Mountains of Silesia, Alps 
of Austria, Bavaria and Eastern Switzerland. 
Poecilopsis liqudaria (Ev.) Kirghiz Steppes. 
Poecilopsis lapponaria (B.) Scotland (Perthshire) Lapland 
southward to Livonia. 
Poecilopsis rachelae (Hulst.) In North America from 
Montana northward along the foot hills of the Rocky Mountains 
to Alaska, eastward to Manitoba. 
Here again we have another genus developed from Lycza ; 
it differs from that genus at all points but its species show 
this separation in varying degrees. The first three, P. 
pomonaria, P. isabellae and P. liquidaria, are fairly near to 
Lycia and form a very compact little group whilst the other 
two species, P. lapponaria and P. rachelae, approach the 
genus Nyssia and connect Lycia and Poecilopsis with that
