Geometrinae (= Geometridae, Meyrick).
Acidaliinae (= Sterrhidae, Meyrick).
Larentiinae (= Hydriomenidae, Meyrick).
Orthostixinae (not represented in Britain).
Boarmiinae (= Selidosemidae, Meyrick).
Except as regards the Larentiinae, I have largely adhered to Staudinger's
arrangement of genera in each of the above subfamilies.
The typical genus of Larentiinae would be _Larentia_, Treit, to which
something over two hundred species are referred by Staudinger, among which
are upwards of sixty that occur in the British Isles. Following some of the
later generic changes, I find that none of our species are left in
_Larentia_, but a few fall into _Hydriomena_, Hubner, and therefore
Hydriomeninae has been adopted for this subfamily. {101}
