156 Dr. C. P. Alexander on 
New Zealand Tipulide, as well as valuable notes and 
observations. It is the only New Zealand species with cell 
M, lacking, a character possessed only by G. jucunda, Osten- 
Sacken, and G. octofasciata, Brunetti (Celebes), among the 
described species of the genus. 
Gynoplistia fulviventris, sp. n. 
Related to G. bimaculata, Skuse; size smaller (wing, ¢, 
72mm.) ; mesonotum heavily pollinose; halteres orange 
throughout; wings uniformly tinged with brown; con- 
spicuous darker brown spots at origin of Rs and at the 
deflection of Ry,;; male hypopygium with a. single pleural 
appendage, the tip of which is strongly curved. 
Male.—Length 775 mm. ; wing 7°2 mm. 
Rostrum and palpi dark brown. Antenne injured in the 
type, apparently with twelve branched flageller segments, 
dark brown throughout. Head dark brown with a sparse 
yellow pollen. 
Mesonotum and pleura with a very heavy yellow pollen, 
which nearly conceals the brown or black ground-colour ; 
pseudosutural fovez large, conspicuous, broadly triangular 
in outline, the surface microscopically punctulate. Halteres 
orange throughout. Legs with the coxe dark, vellowish- 
grey pruinose; trochanters dark brown ; femora and tibize 
yellow, the tips of each rather narrowly dark brown ; meta- 
tarsi brown, the tips dark brown; remainder of tarsi dark 
brown. Wings with a strong brown tinge; stigma darker 
brown, this colour continued along the cord as a conspicuous 
seam at the deflection of R,,;; a smaller but conspicuous 
spot at origin of Rs; veins brown. Venation: As strongly 
arcuated at origin; R,,3 short, about equal to m ; r-m shorter 
than m; petiole of cell M, shorter than the cell ; basal 
deflection of Cu; just before mid-length of cell Ist Mg. 
Abdomen fulvous, a little darker toward the apex of the 
organ; basal tergite infuscated, but not blackened. Male 
hypopygium with each pleurite slender, tapering gradually 
to the narrow apex, the outer face clothed with conspicuous 
reddish sete; a single pleural appendage, narrow basally, 
dilated before mid-length, thence narrowed to the acute, 
strongly curved point ; on the cephalic or proximal margin 
are two protuberances, one opposite the subbasal dilation, 
the second appearing as a small triangular wing some 
distance before the tip. Gonapophyses complex, each bear- 
ing two laterally-directed curved hooks, the more caudal of 
which is very slender and delicate.
