radial joint is short, brownish-black, with a tuft of strong hairs on the 
upper side; the digital joint is large, dark brown, convex and hairy ex- 
ternally, concave within, reddish-brown ; the palpal organs are prominent, 
complex, directed outwards; the most remarkable are two long bristle-like 
processes, and a claw-like process at the base of the outer side. The 
abdomen somewhat resembles that of the female both in colour and form, 
but it is comparatively broader at the posterior end, and the central 
protuberance is shorter, devoid of the yellowish streaks, and the wrinkles 
more defined. 
Var. a., nov. PI. ix., fig. f. 
Length of mature female 7mm. 
The posterior portion of the abdomen bears a resemblance to that of the 
male, the central lobe is short and stout, strongly wrinkled, coloured mark- 
ings absent; the crescent-like termination of the medial band well-defined. 
This example is figured with the tail curled up. This species pairs in 
February-March, possibly earlier; the female fabricates, generally on the 
ends of manuka twigs, a conical pale copper-coloured cocoon of a soft silky 
texture, 9 mm. in height, and about the same in diameter, comprised within 
is a cocoon 8 mm. in diameter, containing about 49 spherical straw-coloured 
agglutinated eggs. -

Thlaosoma olivacea, sp.n. Pl. ix., fig. 4. 
Adult female, length 5 mm., breadth of abdomen at the widest part 54 
mm. 
The cephalothorax is broad, rounded at the sides, constricted anteriorly, 
it is of a dull greenish-yellow colour, sparingly clothed with silky whitish 
hairs, the sides are marked with dark olive, a broad whitish medial band 
extends from the ocular area to the region of the thoracic junction, which 
is a little raised and divided into two subconical points by a longitudinal 
cleft. The fore part of the caput, which is of a red-chestnut colour, is 
upturned, ending in a subconical point, on its face are placed the four 
minute central eyes, which are divided by a broad yellow cross ; the laterals 
are seated on small tubercles. 
Relative length of legs 1, 2, 4, 8, those of the first and second pair are 
much the longest (9 mm.), and about equal in length; the femoral joints 
are rather stout and armed along the outer side with several rows of minute 
spinous tubercles, the outer rows being the strongest; the femoral joint of 
the third, and the tibiw of the first and second pairs, are similarly armed, 
but to a less extent; the femoral and genual joints have a yellowish-brown
