Genus Gonomyta (Mg.) O.-8. 
Subgenus LipopHLEPS Bergroth, Psyche, vol. 22, p. 55, 1915. 
(New name for Leiponeura Skuse, preoccupied by Liponeura Lw.) 
This subgenus has rather numerous representatives in most tropical 
countries, the first known being Gonomyia manca О.-8., from North America. 
Recently Alexander has recognized that the two species of Leiponeura 
described from Australia by Skuse are referable to Gonomyia, and has 
adopted Leiponeura as a subgenus, describing many new species. The 
name Leiponeura cannot stand, in view of the previous existence of 
Liponeura, the difference being merely one of transliteration. I follow 
Alexander in regarding Lipophleps as a subgenus of Gonomyia, rather than 
as a distinct genus, as Bergroth claims it should be regarded. 
wing to the loss of the vein Ву, members of this subgenus are liable 
to be confused with Dicranomyia, to which they have actually very little 
affinity. The sixteen-jointed antennae, the strongly divergent veins R, and 
R,+,, and the structure of the male hypopygium will distin ish them. 
As in Gonomyia (s. str.), yellow or orange coloration is of frequent 
occurrence on the sides of the thorax and abdomen. The New Zealand 
species does not appear to be particularly closely allied to any of those 
described from Australia.

thought to be of generic or subgeneric value, but the remarkable structure 
of the hypopygium is similar in all, and there can be no doubt that they 
are in reality closely related. It is equally certain that they are not 80
