RUNCINIA. 75 
The mawilie, labium, sternum, and cowal joints of the legs are yellow-brown, not quite so dark as the annuli 
on the legs. 
The abdomen is of the pentagonal form common among the Thomiside in this sex. It is of a cream-yellow 
colour, with a brownish-yellow angular marking, formed by two oblique stripes meeting in front and 
open behind, on the fore part of the upperside, followed by two irregular patches of the same colour in 
a transverse line nearly halfway towards the posterior extremity, and wider apart than the ends of the 
oblique stripes. The anterior sides of the abdomen, as well as a broad central longitudinal band on the 
underside, are also of a brownish-yellow hue. The form of the genital process is characteristic and 
distinct, although rather inconspicuous. 
If future research should prove this to be not the female of the male above described, the short diagnosis 
given will perhaps enable it to be removed to its proper place. 
Hab. Panama, 3 Bugaba, ? Volcan de Chiriqui (Champion). 
Runcinia rugosa, sp. n. 
Adult female, length 23 to rather over 23 lines. 
In its general form and structure, as well as in the position of the eyes, this spider is of the usual type. The 
whole surface is more or less covered with short, blunt, prominent bristles, some almost spinous in their 
character, some (on the caput and abdomen) showing a tendency to become slightly clavate at the 
extremity. 
The cephalothorax is of a reddish-yellow-brown hue, deepest on the sides of the thorax, and a broad central 
longitudinal pale band gradually merges into the normal colour of the rest on the caput; on the sides 
are traces of some indistinct converging and oblique pale lines. A transverse curved yellowish line runs 
across the caput through the middle of the ocular area. 
The legs are rather strong and not very long, 2,1, 4, 3. Their colour is similar to that of the cephalothorax, 
and there are strongish spines in pairs beneath the tibiee and metatarsi of the first and second pairs ; 
the number of pairs of spines does not seem to be quite similar in different examples. The third 
and fourth pairs of legs are pale yellowish, slightly marked with brown near the joints, and have no 
spines. 
The falces, maxille, and labiwm are rather lighter coloured than the two anterior pairs of legs; and the 
sternum is similar in colour to the two posterior pairs. 
The abdomen is of the ordinary (Thomisid) pentagonal form—truncated before, broad behind ; it is of a dull 
yellow-brown hue, marked with deep brown, transverse, broken and sometimes confluent, curved, parallel 
lines on the hinder half, with others differently arranged on the fore part of the upperside. The 
ordinary ruge are also marked with small pale spots, giving a generally speckled appearance. Under- 
neath, the colour is a uniform pale yellow-brown. The genital aperture is small and inconspicuous, but 
of characteristic form. 
Hab. Panama, Bugaba (Champion). 
Runcinia depressa, sp. n. 
Adult male, length 1 line ; adult female, length 2 lines. 
The general form of this species is short, broad, and flattened. 
The cephalothoraw of the male is as short as, or shorter than, broad, and its surface (chiefly of the thorax) is 
granulose, with short spine-like bristles. The colour is rather bright red-brown, the normal converging 
indentations of a deeper hue, and there is a narrow nearly black margin. Along the centre of the 
hinder part, and reaching a little into the caput, is an indistinct red band sharply bifid in front; a 
conspicuous white transverse curved line runs through the middle of the ocular area. The height of 
the clypeus is nearly or quite equal to half that of the facial space, and on its lower margin are several 
strong prominent pointed spines. 
The eyes are rather larger than usual, and the two middle ones in each row are distinctly wider apart than 
each is from the lateral eye in the same row.
