Psyllidae of New Zealand — Tuthill 
91 
segment short; dorsal valve straight, blunt; 
ventral valve with prominent hump, sharp. 
HOLOTYPE, male, allotype, female, and 
several paratypes, Massey Agricultural Col- 
lege, October 27 and November 10, taken 
from Acacia decurrens. Additional paratypes 
from same host, Waitakere, September 29. 
HOST PLANT: Acacta decurrens Willd. 
This small, beautifully marked species is 
by far the least common of the three found 
on this species of wattle. It is very active and 
quite delicate, which makes the capture of 
intact specimens difficult. 
Psylla (Acizzia) acaciae-baileyanae 
Froggatt 
1901 Psylla acaciae-haileyanae Froggatt, Linn. 
Soc. N. S. Wales, Proc. 19OI: 257, pis. 
14, 16. 
1924 Arytaina acacia-haileyanae Pettey, Union 
S. Africa, Dept. Agr., Ent. Mem. 2: 21, 
pi. 1. 
1932 Psyllia uncata Ferris and Klyver, New 
Zeal. Inst., Trans. 63: 49, 53, pis. 12, 13. 
Length to tip of folded wings 1.1-1. 6 mm. 
This minute species is abundant on Acacia 
haileyana and probably occurs wherever it 
grows in New Zealand. I have examined 
Froggatt’s types and find them to be identical 
with uncata of Ferris and Klyver. It is un- 
questionably closely related to the other 
Australian species which inhabit the wattles 
in such abundance and is, therefore, neces- 
sarily kept in the genus Psylla even though 
the propleura are as in Arytaina. 
In addition to those found on the ordinary 
host, I found it breeding in abundance on 
Acacia podalyriaefolia at Massey Agricultural 
College. 
HOST PLANTS: Acacia haileyana F. v. M. and 
A. podalyriaefolia Cunn. 
Psylla (Acizzia) hakeae n. sp.

Length to tip of folded wings 2.0-2.25 mm.

genal processes, base of antennae, legs, and 
margins of some sclerites lighter; abdomen
