*Useful supplementary characters, which separate most individuals of one species from most individuals of the other. 
fCharacters that appear to be good distinguishing features 
ington Plateau (Lower Ballunjui Falls), Oc- 
tober 30, 1955, 1 male, T. E. Woodward ; 
Brisbane, 4 males, 2 females, 1954, T. E. Wood- 
ward. New South Wales: Barrington Tops, 
2 males, 2 females, December 22, 1954, 
T. E. Woodward . 
SEASONAL OCCURRENCE: Adults have been 
recorded from South Queensland in January, 
March, May, June (early), October, and De- 
cember (i.e., in all seasons except winter) and 
from New Zealand (where less extensive col- 
lecting has been done) in January, February, 
and April. Late instar nymphs have been col- 
lected in Queensland in January and June and 
in New Zealand in January and February. 
corrigendum: In Woodward (1954: 43), 
11th line from bottom of first column, the 
word "width” should read "length,” as the 
figures would indicate. 
Felisacus filicicola (Kirkaldy, 1908) 
colour: All the Samoan specimens noted 
below differ in some respects from the de- 
scription of two Fijian specimens given by the
