78 ARANEIDEA. 
appear to be devoid of spines, but there are some in pairs beneath the tibie and metatarsi. The third 
and fourth pairs of legs are without spines. 
The maxilla, labium, and sternum are of a uniform yellow colour. 
The abdomen is of a subpentagonal form, narrowest and rather rounded in front and broadest behind, but less 
pointed at its posterior extremity than in some other species. Its colour is a uniform yellowish-white, 
with the five normal depressed points on the upperside yellow-brown. The genital aperture is very 
small, but characteristic. 
Hab. Panama, Bugaba (Champion). 
‘This species is nearly allied to R. sagittata, but may easily be distinguished by the 
form of the genital aperture, and also by the different armature and colouring of the 
legs, as well as by the colours and markings and form of the abdomen. 
Runcinia lutea, sp. n. 
Adult female, length 23 lines. 
This species is very nearly allied to 2. propinqua, but the cephalothorax wants the longitudinal lateral reddish- 
brown bands. The legs also are weaker and unicolorous, and the spines beneath the tibie of the first 
and second pairs are weak, The genital aperture is very small, but characteristically different. In most 
other respects there is a great similarity. The whole of the fore part of the spider is yellow with a 
slight.brownish tinge and with a white triangular marking at the thoracic junction, joined to the ocular 
area by a central white line. The abdomen is yellowish-white, with a well-defined deep red-brown patch 
on each side at the fore extremity. The ocular area is whitish, and a distinct white transverse line runs 
round the caput below the eyes. The cephalothorax is narrowly margined with white.

Runcinia annulipes, sp. n. 
Adult male, length 14 lines. 
Cephalothorax slightly broader than long, but of the usual form ; colour yellow-brown, with a broad pale 
yellowish central band, not, however, reaching the ocular area, with which it is connected by a yellowish 
central line bisecting that area; a very distinct white marginal line runs round the front and sides of the 
caput. 
The eyes are on rather stronger than usual grey or whitish tubercles, and in each row the interval between the 
two central eyes is slightly but distinctly greater than that which separates them respectively from the 
laterals. The four centrals form a trapezoid the front side of which is shorter than the hinder, and the 
sides rather shorter than the front. The laterals of the anterior row are the largest of the eight, and the 
height of the clypeus is scarcely more than equal to the diameter of one of the fore central eyes. 
The surface of the cephalothorax is apparently devoid of granulosities, but has a few short spine-like bristles 
on each side of the hinder part of the thorax. 
The falces are similar in colour to the cephalothorax, subconical in form and furnished with strong promi- 
nent bristles in front. 
The legs, 2, 1, 4, 8, are not very strong, but the first two pairs are long and the third and fourth short, as 
usual. The first two pairs are of a yellow-brown hue, for the most part considerably darker than the 
cephalothorax, the femora being the darkest, finely granulose, and with a few spine-like bristles along 
the hinder margin. The tibiew, metatarsi, and tarsi have each a distinct broadish though not sharply 
defined yellowish annulus at their base; they are well furnished with hairs and long bristles, but devoid 
of spines, excepting perhaps one or two beneath the metatarsi. The two hinder pairs of legs are pale 
yellow, the tibie with two or three spines or spine-like bristles on their upper or posterior side. 
‘The palpi are short aud of a pale yellowish colour. The radial is shorter than the digital joint, and has several 
spine-like bristles on it, and at the outer extremity it is produced into a tapering apophysis about equal to
