ARACHNIDA—RAINBOW. 13 
Falces.—-In each case similar in colour to cephalothorax, long, arched, vertical, 
strong ; inner angle of each falx armed as in the Q with two large teeth and one small 
one; outer angle armed with five small teeth ; fang, long. 
Mazille.—tLong, arched, yellow brown (darker in some specimens), curving inwards ; 
apices produced, somewhat club-shaped ; inner apical angles rather obliquely truncated ; 
surface of each sparingly clothed with stiff, bristly hairs. 
Labium—Yellow brown, lighter at tip; nearly as broad as long, rather more 
than half as long as maxille; apex rounded; sparingly clothed with short, blunt, 
bristly hairs. 
Sternum.—Yellowish, suffused with dark brown laterally; arched, cordate, 
terminating in a somewhat obtuse point between fourth pair of coxze ; surface moderately 
clothed with short, stiff, black hairs. 
Abdomen.—Ovate, moderately overhanging base of cephalothorax ; hairy ; arched ; 
colour and ornamentation variable (figs. 8 and 9), some examples being much darker 
than the others; in the majority of cases the abdomen of the g is dark brown (almost 
black), with pale yellowish, longitudinal and transverse bars (echelons) and spots ; other 
examples are of a lighter brown, with large yellowish areas relieved by dark-brown 
transverse bars (echelons) or dark-brown patches; in the dark forms the underside is 
dark yellowish brown, with two slightly curved lateral, longitudinal yellow stripes, 
which latter commence near the rima epigasteris and terminate just in front of the 
spinnerets ; in the lighter coloured forms the ventral surface is yellowish and suffused 
in parts with brown.
