a rather broad whitish ring just beyond middle of tibiae ; remainder of 
legs pee (hind legs missing). Wings greyish-tinged, darker towards tip

any other New Zealand species; R, almost straight at base; cross-vein r

The peculiarities of this species are probably sufficient for it to be made 
the type of a new genus, пяр YA til the male is known it had better be 
regarded as an aberrant Gynop istia. 
Genus CEROZODIA Westw. 
As already noticed by Osten-Sacken, this genus is very closely allied to 
Gynoplistia and to the South American Ctedonia, and it is by no means 
impossible that the three will some day be united. Some species of Gyno- 
plistia (especially G. magnifica) approach Cerozodia in the long vein Sc, ; 
others (such as G. speciosa) in the number of joints on the antennae, while 
in this last ple: Ctedonia is intermediate between Gynoplistia and Cerozodia. 
The male hypopygium of the New Zealand species of Cerozodia is very 
similar in structure to that of G. magnifica ; all four Cerozodiae are remark- 
ably alike in this organ, and I doubt if the small differences I have observed 
between different specimens are of any value for distinguishing the species ; 
I have therefore not described them. C. pulverulenta is possibly only a 
variety of C. paradisea, and both are just possibly only varieties of 
C. plumosa, but C. hudsoni is certainly a good species. The number of 
simple joints at the tip of the male antenna seems more or less constant for 
the species, but the principal characters relied on for separating them a 
those of the wing-markings. 
Apart from the New Zealand forms, only one species of the genus we 
been described, C. interrupta Westw., from Western Australia. Dr. C. P. 
Alexander informs me that he has seen two species from Tasmania.

The о. of Osten-Sacken’s type (which I Tenis examined) have 
2+ 3+ 32 + 2 joints, as stated by the describer : о basal ones, three 
remose joints, the branches of which are directed reip thirty-two 
joints with the branches directed upwards (the branch of the thirty-second 
is a mere stump); the last two joints have no branches, the last being 
rather elongate.” Thorax and abdomen reddish-brown, without distinct 
than in the othet species, and have all veins more or less distinctly borde 
with brown, the border of vein Cu being particularly broad for the whole . 
length of vein in cells M and Cu,. There is a small dark-brown spot in | 
base of cell R, a very small one over base of Rs, and a moderately large 
cloud below the РЗ нец stigma. Basal section of R,,, strongly curved, 
about six times as long as r-m; cell M, not longer than its stem; Cu,,
