For the photographs I am indebted to Mr. S. A. Rumsey, of the Plant Diseases Division, D.S.I.R., Auckland. The type specimen of Rhopalimorpha (Lentimorpha) alpina subgen. and sp. nov. was one of a series of insects on loan from the Auckland Museum to the Plant Diseases Division, Auckland, and was labelled “n.sp.?” by Mr. D.
