mm. Blunt behind, margin concave opposite 
coxae III and IV.

slender with the tarsus little swollen. Short 
retrolateral apophysis at the distal end of the 
tibia. The conspicuous white hairs on the 
palp have been mentioned above.

Claws: The retro with 4-6 large pectinations, 
the pro with 3 or 4 minute ones in addition 
at the proximal end of the row. Spines: Meta- 
tarsi I and II with 2 pairs, III with a circlet 
of spines at each end, IV with spines in the 
middle as well as at the ends. Tibiae: I, 3 
pairs and 1 proximal prolateral: II, 2 pro- 
lateral, 2 pairs and 1 proximal retroventral; 
III and IV, 1 distal pair and 1 proventral, 3 
pro and 3 retrolateral, 1 proximal dorsal. 
Patellae: I and II, 1 prolateral; III and IV, 
1 pro and 1 retrolateral. Femora: 1, transverse 
distal dorsal row of 3 followed by 2 dorsal. 
II, III and IV have 4 in the transverse row. 
Trichobothria: In a single row on tarsi and 
metatarsi and a double row on tibiae. 
Abdomen: Length 2.39 mm., breadth 1.52 
mm. Ovoid. 
This spider resembles some from Australia 
placed by Koch In several poorly character- 
ized genera. It seems best to place it in a new 
genus until the position is clearer, rather than 
to suggest on doubtful grounds a faunal 
affinity between Fiji and Australia. 
TFIERIDIIDAE 
Conopistha gracilis (L. Koch) 
1 $ Savaii. 1 9 Upolu. 
Theridion albostriatum L. Koch 
Icf Aitutaki. 1 cf , 19 Korolevu, Viti Levu. 
These specimens are somewhat doubtfully 
placed in this species, recorded from Aus- 
tralia and Tonga. They appear to be the same 
as some collected in buildings in Upolu 
(Marples 1955) and also tentatively placed 
here. 
Theridion kraussi sp. nov. 
1 9 Kolo-i-Suva, Viti Levu. 
female. Length 4.58 mm. Colour brown, 
abdomen lighter in front and on the sides. 
Sternum with 3 lateral and a posterior median 
dark marks. 
Carapace: Length 1.54 mm., breadth 1.24 
mm. Heart-shaped, the cephalic part pro- 
jecting forward with prominent eyes, AME 
overhanging the clypeus, thoracic part domed. 
Smooth surface with some scattered bristles 
almost all on the cephalic part. 
Eyes: 8. AME dark, the remainder light with 
reddish pigment. From above the anterior 
row strongly recurved, posterior row straight. 
Breadth of eye group 0.56 mm. Ratios of the 
diameters of the eyes and of their distances 
apart: AM, 193; AL, 142; PM, 164; PL, 163; 
AM-AM, 135; AM-AL, 46; AM-PM, 182; 
PM-PM, 147; PM-PL, 138; L-L, 0; clypeus, 
365. 
Chelicerae: Slender, joined at base, no boss. 
3 teeth on the promargin of the groove. 
Maxillae: Long, very much longer than the 
lip, converging but not meeting. Scopula on 
median margin and anterior median angle. 
Black serrula lateral to it. 
Lip: Twice as broad as long. 
Sternum: Length 0.88 mm., breadth 0.79 
mm. Three slight indentations on each side. 
Posterior blunt point between coxae IV which 
are well separated. 
Palp: Claw with 4 pectinations and pectin- 
ated bristles on the tarsus. Two pairs of 
trichobothria on the tibia. Tarsal organ 24 
per cent of the length of the tarsus from its 
distal end.
