large teeth until the seventieth or eightieth joint, where the antennae 
become cylindrical and hairy as stated above. In immature specimens 
the antennae show no differentiation whatever, appearing very much like 
those of the female, but rather thicker at base. к i 
These differences seem quite individual; whilst another character may 
be considered as a real male dimorphism, as formerly relat by Griffin 
among Stenopelmatids.* The two adult males found at Karori present 
‘a rather bigger head, with larger, strongly-notched eyes, and antennae 
thicker at base. They really seem somewhat different from the males of 
Kaiparora, but, both unfortunately lacking the apex of the abdomen, it 
is impossible to state whether they differ in other characters. 
It may be added that P. fascifer does not seem to be exclusively 
cavernicolous, as I received a female from Mana Island which has certainly 
been caught outside of caves. Very likely the species has a mode of 
living similar to that of our European Dolichopoda or Troglophilus. 
Genus PrLEroPLECTRON Hutt. 
Pleioplectron cavernae Hutt. 
- Cave near Taupo, F. W. Hutton, 18th February, 1899; one male, one 
immature female (British Museum). 
A few peculiarities must be added to Hutton's description of this species. 
one; tibiae with 4 apical spurs, 4 spines above (3 external, 1 internal), 
and 3 on each inferior margin. Posterior femora armed with a small 
genicular internal spine, 6—7 rather strong ones on the inferior internal 
margin, and only 2 small ones near the àpex of the external margin; 
very short, cylindrical, inserted about on the middle of the. lateral 
ins of the plate. Cerci rather long, straight, almost as thick at apex 
as at base. 
I have seen no adult female, but the subgenital plate of the immature 
one shows a rounded notch at the apex.
