237 
Fig. 1. a, Felisacus dauloi n. sp., female, head and 
pronotum; b, Felisacus elegantulus (Reuter), female, 
posterior margin of pronotum; c, Felisacus filicicola 
(Kirkaldy), female, posterior margin of pronotum. 
apex; translucent portion above ridge in form 
of a subtriangular lobe, considerably nar- 
rowed shortly before apex. 
Length: 5.1 mm.; width across hemelytra, 
1.25 mm. 
The measurements given above in paren- 
theses are in millimeters. 
colour: Head, thorax, abdomen, and first 
antennal segment shining fulvous; apex of 
first antennal segment tinged with reddish 
brown, second segment blackish brown with 
reddish tinge, third and fourth black; eyes 
dark; type female with a fine red line between 
and above level of antennifers; type female 
without trace of infuscations on pronotal 
shoulders; rostrum brown; abdomen tinged 
with green. Scutellum very pale and less shin- 
ing fulvous, darker brown along margins. 
Legs pale yellowish brown; apices of femora 
and bases of tibiae darker and tinged with red; 
rest of femora slightly tinged with green; 
second and third tarsomeres infuscated. Hem- 
elytra with veins yellowish brown, somewhat 
infuscated at basal angle of cell, along anal 
vein and posterior margin of clavus, narrowly 
along costal margin of corium, and very nar- 
rowly around margin of membrane; a short 
sooty band on corium at apex of claval suture; 
rest of corium and membrane colourless, 
transparent (membrane with the usual rugu- 
lose surface, iridescent in reflected light); 
clavus slightly more opaque. 
holotype female: Daulo Pass, Central 
Highlands, New Guinea, ca. 8,000 ft., August 
20-22, 1956, sweeping ferns in rain forest, 
T. E. Woodward. Named for place of collec- 
tion. Deposited in Queensland Museum. 
F. dauloi most nearly resembles elegantulus 
(Australia and New Zealand) and is much 
more closely related to it than to the one other 
known New Guinea species, nigricornis Pop- 
pius, described from the lowlands of Huon 
Gulf. Quite likely dauloi is a relict species 
persisting in the highlands of New Guinea 
after their separation from the more southerly 
regions of Australia. The close resemblance 
between dauloi and elegantulus becomes ap- 
parent from a comparison of the figures given 
above with those tabled below. The main dif- 
ferences are those of size, notably the greater 
total length of dauloi , its wider head, longer 
head, pronotum, hemelytra, and first three 
antennal segments. But in almost all propor- 
tions, including those by which elegantulus 
differs from the closely related filicicola , the 
specimen of dauloi falls within or almost with- 
in the known range of the former species. The 
only exception in the table is the ratio of the 
width behind the eyes to the width across the 
eyes. The rostrum is proportionately shorter 
than in elegantulus and the posterior margin of 
the pronotum rather more deeply excavated. 
The valvulae of the female differ as figured. 
In colour dauloi is very similar to the pale form 
of elegantulus , but the first antennal segment 
is paler. 
From filicicola the new species differs in its 
greater size, including width of head and 
pronotum at base and length of head, prono- 
tum, hemelytra, and third antennal segment; 
the paler colour; the different ratios for width 
of pronotum: width of head, antenna III: I, 
antenna I: width of pronotum, antenna II: 
width of pronotum, posterior: anterior width 
of pronotum; the differently formed valvulae. 
From the other species of the elegantulus 
group dauloi differs notably as follows: from 
nigricornis Poppius in the larger size, paler 
colour (particularly of head, pronotum, scutel-
