and metatarsi of the first and second pairs ; those on the metatarsi are much the strongest 
and most numerous. The femora of the first pair have three smaller erect spines in a 
longitudinal line on the upper side. 
Tli q palm are short, and similar to the legs in colour and armature. 
The falces are strong, moderately long, subconical, and a little projecting forwards ; 
they are of a reddish yellow-brown colour, marked and suffused with whitish-yellow, and 
furnished with bristles in front. 
The maxillce and labium are normal in form, and similar in colour to the legs. 
The sternum is oval, blunt-poiuted behind, and broadly truncated in front ; it is of a pale 
whitish-yellow colour, thinly clothed with slender, erect, bristly hairs. 
The abdomen is oval, rounded in front and obtusely pointed behind, tolerably convex 
above, and thinly clothed with hairs. The upper side is of a whitish -yellow or dull cream- 
colour, thickly speckled with minute red-brown specks ; the sides are rugulose, and pale 
yellow-brown ; the rugulosities yellow-white, minutely spotted with red-brown ; the under side 
is pale whitish -yellow, like the sternum. The ordinary longitudinal, dentated band on the 
abdomen is imperceptible ; probably, however, some variety exists in this respect in different 
examples.

Immature male : length just, over 2 lines. 
The cephalothorax is of ordinary form, and has a whitish, narrow marginal border. The 
sides are of a dull reddish yellow-brown colour, irregularly but distinctly marked with short 
whitish streaks and markings, leaving a broad, median, longitudinal, nearly white band, 
slightly narrowest at its hinder extremity ; the fore part of this band contains the normal spade- 
shaped marking, which is of a dull pale-brownish hue, rather peculiar in form, and marked 
With some red-brown lines and markings ; its posterior extremity being also continued, by a 
red-brown line, to the thoracic indentation. 
The eyes are in the normal position ; the four central eyes form very nearly a square, the 
longitudinal being slightly greater than the transverse diameter, and the tore side slightly 
shorter than the hinder one ; the interval between those of the hind-central pair is distinctly 
less than that between each and the hind-lateral eye on its side, and the interval between 
those ot each lateral pair is equal to that between the fore- and hind-central pairs. I he 
height of the clypeus is scarcely more than one- third of that of the facial space. 
The legs are tolerably long and strong ; those of the second pah’ are slightly longer than 
those of the first, and the third pair are a little the shortest, 'ihey are of a yellowish colour, 
more or less suffused and striped longitudinally with white, especially on the femora of the 
first and second pairs, which are also prettily spotted with reddish yellow-brown. The other 
legs are also spotted, though more faintly ; the tarsi and metatarsi of all being of an almost 
unmarked pale-yellow colour. The tibiae and metatarsi of the first and second pairs are 
armed with a few longisli, not very strong, spines, in two parallel longitudinal rows on the 
under sides. 
The palpi are similar in colour to the legs.
