well defined. In colour the cephalothorax is of a glossy black brown. The clypeus is 
somewhat protuberant and prominent; and its height exceeds the length of the space 
occupied by the fore and hind central pairs of eyes, about equalling that between the 
fore eyes of each lateral pair. A longish narrow longitudinal indentation runs backwards 
from each hind lateral eye. 
Eyes in four pairs, on the front and summit of the caput; they do not differ much in 
size; those of each lateral pair are seated rather obliquely on a tubercle; those of the 
fore central pair are the smallest of the eight, and near together, but not contiguous; 
those of the hind central pair are rather further apart than those of the fore central pair ; 
and the space between these two pairs is about equal to that occupied by the eyes of the 
fore central one, and rather greater than that between each of the four central eyes and 
the fore lateral on its side. The four pairs thus occupy a longish transverse oval space. 
Legs moderately long; relative length 4, 1, 2, 3; strong, of a bright orange-yellow 
eolour, furnished sparingly with hairs. 
Palpi rather short; cubital joint rather largest at its fore extremity, which is a little 
produced in front; radial joint very short, but strong, and spreading out on all sides ; 
mostly so rather on the outer side in front, where it is furnished with a tuft of bristly 
hairs; digital joint short, broad at the base, and blunt-pointed at the extremity. Palpal 
organs fairly developed, prominent, but not very complex; they have a strong black 
spine, eurved in a circular form, on their outer extremity ; and from within its curvature- 
there projects downward a strongish yellow red-brown, black-tipped, sharp-pointed 
corneous process. Amongst and in connexion with these is some whitish semitrans- 
parent membranous substance. In colour the palpi resemble the legs, except the radial 
and digital joints, which are strongly suffused with dull black. 
Falces strong, conical, vertical, and prominent near the base in front; their fangs are 
long and curved; and there are some longish sharp teeth near their inner extremity. 
Maxille long, strong, roundly and obliquely truncate on the outer extremity, and 
inclined towards the labium, which is short and semicircular. These parts, with the 
falces, are similar in colour to the cephalothorax, the maxille, however, being tinged 
with yellowish towards their extremities. 
Sternum broad, heart-shaped, black and glossy, and furnished sparingly with some 
erect hairs. 
Abdomen rather large, oval, flattened-convex above, and projecting over the base of 
the cephalothorax; it is of a glossy black, furnished sparingly with very short hairs. 
Four impressed red-brown dots or punctures occupy the centre of the upperside; these 
dots form a square whose anterior side is rather the shortest. On the underside two 
longitudinal rows of pale dots run backwards from the plates of the spiracles (which are 
yellowish in colour) and converge to the spinners; near the centre of the space included 
by these lines are four other impressed red-brown dots, rather smaller than those on the 
upperside, and forming a smaller though similarly shaped figure. The spinners are 
brownish, with a yellow tinge. 
An immature female resembled the male in colours and markings. An adult male, 
and immature examples of both sexes, were contained in a collection of pos made by
