Psyllidae of New Zealand — Tuthill 
89 
Several additional paratypes, Houhora, Febru- 
ary 16, R. A. Cumber. 
HOST PLANT: Acacia melanoxylon R. Br. 
This strikingly marked species, which ap- 
pears to be nearest P. acaciae of any of the 
species found in New Zealand, was teeming 
on the twigs of the host plant, in all stages of 
development, early in October. 
Psylla (Acizzia) uncatoides (Ferris and 
Klyver) 
1932 Psyllia uncatoides Ferris and Klyver, New 
Zeal. Inst., Trans. 63: 49, 53, pi. 13. 
Length to tip of folded wings 2.0- 2.5 mm. 
This appears to have the widest range of 
hosts of any of the species of Psylla known in 
New Zealand. It was taken in abundance on 
Albizzia lophantha at Otiria and New Ply- 
mouth, October 2 and 30, on an unknown 
species of Acacia at Whakarewarewa, Decem- 
ber 4, and Acacia verniciflua at Palmerston 
North, February 15. It was originally de- 
scribed from specimens collected from A. 
melanoxylon. 
The specimens on Acacia sp. from Wha- 
karewarewa and, even more, those on A. 
verniciflua have the membrane of the fore- 
wings yellow. The marking of the forewings 
is variable in intensity as is the degree of 
marking on the dorsum. 
Psylla (Acizzia) albizziae (Ferris and 
Klyver) 
1932 Psyllia albizziae Ferris and Klyver, New 
Zeal. Inst., Trans. 63: 49, 51, pis. 12, 13. 
Psylla (Acizzia) jucunda n. sp. 
Fig. 2 
Length to tip of folded wings 2.25-2.5 mm. 
COLOR: General color variable from almost 
uniformly bluish green to yellow with olive- 
green markings and genae white. Forewings 
clear except for pigmented areas. Latter much 
as in P. acaciae.

Specimens identical with the original de- 
scriptions and figures were taken in great 
abundance and in all stages of development 
on Acacia decurrens wherever this widespread 
species was examined. Adults only were taken 
from Clianthus puniceus. No specimens were 
taken from Albizzia lophantha, only P. unca- 
toides being found on that plant. 
HOST PLANTS: Albizzia lophantha Hook. 
[.^], Acacia decurrens Willd., and possibly Cli- 
anthus puniceus Bks. & S. 
structure: Body surface finely punctate, 
very short sparse pubescence on dorsum, 
longer on venter. Head wider than meso- 
scutum. Vertex flat, with slight discal im- 
pressions. Genal processes somewhat de- 
pressed from plane of vertex, blunt, short, 
0.4 as long as vertex (0.5 as long as medial 
suture), not touching. Frons visible between 
genal processes. Antennae twice as long as 
width of head. Eyes protruding. Thorax 
broad. Pronotum long, descending anteri-
