(PI. XXX., Figs. 1, la.) 



? . Oephalothorax 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 

 cephalica 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. 



Uyes 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, tibise, 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. 



Fakes strong, convex, orange-brown, sparingly hairy. 



Maxilloi 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.
