segment; and in having a row of about twelve channelled hairs round 
the much-produced sternum of the same segment, which forms the end 
of the abdomen.

Numerous dd and ?? from Eudyptes sclateri, N. C. Rothschild col¬ 
lection, no locality given. Probably from one of the southern islands 
of New Zealand. Given me for description by Mr Hugh Scott, M.A., 
Curator in Entomology. 
This species would appear to be closest to A. bifasciattis of Piaget, 
from which it differs in its smaller size; in the chaetotaxy of the abdomen ; 
in the concave vulva; and in the hind end of the d abdomen, the heavy 
chitinous border of which is produced much further forwards and 
inwards. It is easily distinguished from A. hrevipes Giebel and A. water- 
stoni Cummings by the antenna, apart from other differences. 
Family --—-? 
Genus Psittaconirmus, nov. 
This genus is established for the reception of a parasite of Austrahan 
lorikeets, which shows, in conjunction with a general nirmoid form, 
considerable sexual dimorphism, involving the antennae, and a peculiar 
forcipate clypeal front. 
According to the present criteria of classification, this genus should 
be included in the Lipeuridae. But I have good reasons for beheving 
that it would be quite wrongly placed. To begin with, it is indubitably 
closely related to other forms from Australian parrots, which must at 
present be placed in the genus Degeeriella. And secondly, its own 
structure is, apart from the antennae, that of Degeeriella and not 
Lipeurus. In the form of the head, and particularly in the structure of 
the occipital apodemes and the prothoracic skeleton, it agrees with a
