Types.—Holotype and paratype males, Lake Wakatipu, at Kingston, 
(13th December, 1919, R. J. T.) ; both in Cawthron Institute collection.

were found attached to rocks near the shore, showing that the larval 
habitat of this species differs greatly from that of its relative Ph. agilis. 
There is a species closely resembling this, but not yet described, which is 
very abundant around the shores of the three lakes of the Cradle Mountain 
massif, in e lacum Tasmania.
