I have seen the two original specimens (males) in the Museum 
in Oxford. According to Westwood the antennae have 32 joints 
joints 3 to 31 each emit a long branch, beset with a delicate pubes- 
cence. I find in my notes that the subeostal crossvein is almost 
obsolete, and thus the auxiliary vein has the appearance of ending 
in the first longitudinal. 
A species occurring in New Zealand may be referred to the same 
genus. I have seen a male specimen in the Museum in Berlin, and 
have recently received one myself. In both the auxiliary vein ends 
in the first vein; the crossvein which connects it with the costa is 
some distance from the tip, very thin, almost obsolete. 
In my specimen I count 39 joints of the antennae: two basal 
ones, three ramose joints, the branches of which are direeted down- 
wards, thirty two joints with the branches directed upwards (the 
branch of the 324 is a mere stump); the two last joints have no 
branches, the last being rather elongate. In the Berlin speceimen I 
counted 36 joints; joints<1—5 are like the corresponding joints in 
my specimen; thirty joints (instead of 32) have the branches di- 
rected upwards; on the two last joints these branches are mere 
stumps or projections; joint 36 is elongated. The long branches are 
filiform, pilose; the longest, if their curled-up ends were streched 
out, would be equal to one third of the antenna at least. 
Rostrum not longer than the head; palpi rather long (West- 
wood says: palpi perbreves?); as far as I can see, the last joint is 
not longer than the others. Thorax small compared to the length 
of the abdomen; the latter narrow, of equal breadth, very sligthly 
broader at the forceps; the forceps seems to have the same struc- 
ture as in Gynoplistia. Legs comparatively stout; tibiae with 
spurs; empodia present. Wings: venation like that of Gynoplistia, 
with the exception already stated in the course of the auxiliary 
vein; first submarginal cell rather long, its proximal end but little 
distad of the proximal end of the second submarginal; the second 
posterior with a long petiole; the great crossvein near the middle 
of the discal cell. 
The close relationship between Cerozodia and Gynoplistia 
cannot be called in doubt; the generic rights of the former are based 
on the general habit of the body, on the structure of the antennae, 
which are longer, have more numerous joints and much longer, pu- 
bescent. branches, and on in the peculiar course of the auxiliary vein- 
Nothing is known about the females of Cerozodia. 
The two Species of this genus at present known, are:
