from the New Zealand species in the number of antennal joints, and the 
number and position of the extra cross-veins on the wings. І do not follow 
Handlirsch in treating these differences as of generic value. The New 
Zealand species all have sixteen-jointed antennae and two accessory cross- 
veins, these being рце. in cells R, and R,. The neck is elongate in 
all, though less so in T. varipes

markings are lighter than in female; veins are yellow in light parts of

veins. Legs em the femora with a blackish pre-apical ring, other joints

Apart from Дан colour, different wing-markings, dark veins, and 
black antennae, this species differs from T. annuliferus in several structural 
points: the hair on veins is much shorter; the cross-vein in cell R, is 
nearer base of Ё; ; the discal cell is eee ad shaped; and the tarsi are 
relatively shorter, those of the egs scarcely any longer than the 
tibiae. The tibiae and the tarsal joints are much more narrowly tipped 
with brown, not sont 
The two specimens I have examined (both females, in the Oxford 
Museum) differ Ane one another in some respects. The one of which a 
figure of the wing is given appeared to agree very well with Osten-Sacken’s 
description. The other had the legs somewhat shorter and stouter, 
apparently somewhat more densely pubescent ; the oblique wing-fascia 
connected in the discal cell with the curved fascia; vein М, somewhat 
more approximated to Cu,. There is no doubt, however that both belong 
to the same species 
So SLAND : Otago (Hutton). Osten-Sacken’s type male, and two 
females in Oxford Museum, were all collected by C. M. Wakefield, probably 
from Canterbury. Hutton’s record from Wellington requires confirmation, 
as it may have referred to T. neptunus.
