question that future studies must answer. The other species 
belonging to this new group are H. (Z.) fulva (Hutton) and 
H. (Z.) otagana, sp.n. The species described by the writer 
as Macromastiz maori is certainly not a member of this 
group, and likewise does not seem to be a true Macromastiv. 
he presence of a spur on M in exactly the same position as 
found in the three species of Zelandotipula may indicate that 
both of these groups have descended from some Maorian 
ancestor in remote ages past. The discovery of the immature 
stages of H. novare by Mr. Gourlay is of unusual interest. 
The larve resemble those of Holorusia in genera! appearance, 
but the pupe strikingly suggest species of Prionocera. 
Holorusia (Zelandotipula) otagana, sp. n. 
General coloration light grey; centre of vertex and 
median stripe of preescutum ‘obscure rufous ; wings rela- 
tively long and narrow, the pattern but faintly indicated ; 
abdomen uniformly light brown; male hypopygium with 
the outer pleural appendage not produced into a conspicuous 
attenuate point. 
Male.—Length 18-19 mm.; wing 19-22 mm.; wing- 
width 3°8 mm. 
Female.—Length about 20 mm. ; wing 17 mm. 
Frontal prolongation of the head elongate, reddish brown ; 
palpi dark brown. Antenne with the scapal segments 
brownish yellow; flagellum black. Dorsum of head deep 
vufous, with a capillary dark brown median line; inner 
margin of eyes broadly cinereous. 
Mesonotal prascutum light grey with three stripes, the 
median stripe obscure rufous, the lateral stripes varying 
from rufous to dark grey ; scutum light grey, the centres of 
the lobes dark grey; scutellum and postnotum light grey 
with a capillary brown median line. Pleura light grey ; 
dorso-pleural membrane obscure yellow. Halteres pale

-ellow; femora and tibie light brown, the tips darkened ;

hyaline, with a subobsolete pattern, cells C, Sc, 2nd Lt, Ry, 
and R; being suffused with pale brown; outer ends of the 
posterior and anal cells faintly darkened ; the subhyaline 
ground-colour includes cell R; to the apex; no conspicuous 
dark pattern along Rs or M as in novare. Venation : as 
in novare, but the cells longer and narrower, resulting from 
the narrowing of the wing.
