(PI. xxx., Figs. 1, 1 a.) 
$ . Cephalothorax 2'8 mm. long, 3 mm. broad ; abdomen 5*5 
mm. long, 5*8 mm. broad. 
Cephalothorax obovate, arched, broader than long, orange-brown 
relieved by chrome yellow and pitchy-black markings. Pars 
ceplialica arched, truncated in front, orange-brown, ornamented by 
a median line of chrome yellow and a few small concolorous spots; 
in addition to these there are also upon the upper surface two fine 
lateral chrome yellow lines : these commence well forward, curve 
gently first in an outward direction, and then more sharply in- 
wards, ultimately meeting at the base ; on the outer side of each 
of these lines, and commencing at a point immediately below, but 
in a line with the posterior lateral eyes, there is a broad, wavy, 
longitudinal pitchy-black line, which does not terminate until near 
the centre of the cephalic segment ; these lines are narrowest in 
front, become gradually wider, and terminate in an obtuse point ; 
immediately below the anterior row of eyes (the clypeus) there is 
a broad, strongly recurved bar of chrome yellow ; from below each 
lateral eye of the anterior row, there is directed backwards and 
outwards, a narrow, wavy, concolorous line, and immediately 
below the posterior median eyes, there is a rather sharp depression 
or pit which is broadest in front, and has its margins chrome 
yellow. Pars thoracica arched, broad, orange-brown with a large 
triangular patch of chrome yellow at junction of cephalic and 
thoracic segments, and enclosed between the pitchy-black lines 
referred to above. Marginal band chrome yellow, broad. 
Eyes small, black, normal. 
Legs orange-brown, extremities of tibiae of first and second pairs 
nearly encircled with a deep, black band ; extremities of each 
haunch, trochanter, femur, patella, and tibia encircled with a 
band of chrome yellow ; femurs, tibiae, and metatarsi clothed with 
fine adpressed hairs upon their upper surface, and armed with 
small lateral spines ; tarsi hairy ; tarsal claws black. Relative 
lengths 1, 2, 4, 3. 
Palpi short, strong, orange-brown, clothed with fine black hairs, 
and terminating with a small black spine. 
Falces strong, convex, orange-brown, sparingly hairy. 
Maxillce yellow, moderately long, convex, slightly constricted 
at their centre, sparingly pubescent, apices inclining inwards. 
Labium concolorous, rather longer than broad, truncated at tip. 
Sternum yellow, glossy, convex, shield-shaped, sparingly clothed 
with rather long, strong hairs.
