sides of the thoracic region are marked with numerous roundish 
punctures ; and the fore part of the caput is bold and prominent, 
with a strong and pretty high eminence on its occipital portion ; on 
each side of this eminence, at its fore part, just behind the lateral 
pairs of eyes, is a short, somewhat oval, indentation, running back- 
ward towards the occiput; the clypeus is rather full, but retreating, 
and slightly exceeds in height half that of the facial space; when 
looked at in front the occipital eminence is distinctly divided into 
two lobes by a longitudinal valley or indentation ; these lobes (looked 
at from the same point) have a direction slightly divergent from each 
other. The fore side of the occipital eminence, as well as the upper 
part of the caput in front of it, is clothed with a few short pro- 
minent hairs. 
The eyes are small and in the usual position; those of the hind 
central (or upper) pair are placed on the fore part of the summit of 
the occipital eminence, or one on each of the lobes into which it is 
divided ; they are thus very widely separated from each other, and 
form a transverse line rather longer than that formed by the three 
other pairs, which are seated at the upper fore extremity of the 
caput itself; those of each lateral pair are slightly obliquely placed, 
and are contiguous to each other, the foremost being separated from 
the fore central eye nearest to it by the space of an eye’s diameter ; 
the eyes of the fore central pair are the smallest of the eight, but 
not quite contiguous to each other. 
The /egs are short, moderately strong, and of a yellow-brown 
colour, tinged with reddish; they are furnished with hairs and a 
very few slender erect bristles ; and their relative length is 4, 1, 2, 3. 
The palpi are of moderate length and strength; their colour is 
pale yellow-brown: the cubital joint is strong, its fore extremity 
much stronger than its hinder one, and it is also much longef than 
the radial joint ; this latter is very short and weak, but has its fore 
extremity on the inner side produced into a longish, curved, taper- 
ing apophysis, whose point is directed outwards ; and opposed to 
it is asmall prominent, obliquely truncated projection, which springs 
from the outer side of the extremity of the joint; the digital joint 
is rather small, but of ordinary form ; the palpal organs are pro- 
minent and rather complex, with a somewhat circularly curved, 
reddish brown spine connected with their fore extremity. 
The falces are small, directed backwards, and armed with a few 
very minute teeth towards their extremities on the inner sides ; 
their colour is similar to that of the cephalothorax. 
The mazille and labium are similar in colour to the falces, and 
of normal character in other respects. 
The sternum is of ordinary form, but very convex ; aud its surface, 
though glossy, is thickly covered with small, round, shallow punc- 
tures ; its colour is similar to that of the cephalothorax. 
The abdomen is of tolerable size, not particularly convex above, 
but projects closely and considerably over the base of the cephalo- 
thorax ; its upperside is completely covered by a dark, rich yellow- 
brown, coriaceous epidermis, pretty thickly marked with roundish
