lum, clavus, and first antennal segment), rela- 
tively shorter pronotum and rostrum, longer 
second antennal segment in proportion to 
first; from jacobsoni Poppius in the greater 
size, head without brown crossbar, paler 
pronotal base, first antennal segment and 
hemelytra, the nonrugulose crown, the longer 
third antennal segment relative to second, the 
relatively shorter pronotum; from ochraceus 
Usinger in the greater size, paler cuneus and 
inner clavus, relatively smaller eyes, pronotum 
broader at base in proportion to length of 
antennal segments I and II, corium longer in 
proportion to pronotum ; from amboinae Wood- 
ward in the much greater size, paler colour 
(particularly of first antennal segment and 
hemelytra), the relatively shorter rostrum, the 
proportionately longer third antennal seg- 
ment, the narrower eyes in proportion to 
vertex, the pronotum wider at base in propor- 
tion to anterior collar, the corium longer in 
proportion to pronotum; from adamsi Car- 
valho in the greater size, different colour 
(especially paler first antennal segment), rela- 
tively shorter rostrum, relatively longer second 
antennal segment, relatively narrower eye in 
proportion to vertex. 
Felisacus elegantulus (Reuter, 1905) 
colour: Of the two main colour forms 
(Woodward, 1954), only 2 of 20 males and 2 
of 12 females from Australia are of the second 
type (extensive red coloration on head; pro- 
thoracic shoulders not or scarcely infuscated) . 
This form appears to be much less prevalent 
than in New Zealand, where it is represented 
by three-fifths of the specimens examined. 
There does not seem to be any correlation 
between colour and season.

are redrawn for comparison with those of 
flicicola , since previously (Woodward, 1954; 
fig. 5) they were drawn in situ on the pygophor. 
Female: (Fig. 2a, b) First (mesial) valvulae 
narrowly rounded at apex. Second valvulae 
more narrowly rounded at apex than in filici- 
cola , much less so than in dauloi\ dorsal trans-

species. The valvulae figured are of an Aus-

females are similar in all respects. 
OVARIAN EGGS: (Fig. 3f) Short ellipsoid, 
slightly curved; opercular end indented as 
shown; length 0.60 mm., width 0.35 mm.
