RUNCINIA. 17 
truncated. The sides and hinder part are longitudinally and transversely rugulose, as well as the rest of 
the upperside; each interval between the ruge has a series of very minute tubercular denticula. The 
colour of the abdomen is dull yellow and cream-white, the latter colour most suffused on the upperside, 
but chiefly following the direction of the ruge. In some examples the sides are marked with one or more 
fine black lines. In one or two specimens the ground-colour of the abdomen is dark yellowish-brown. 
The genital aperture is small, inconspicuous, but of characteristic form. 
Hab. Guatemata, Cahabon and Chicoyoito (Sarg). 
Runcinia sagittata, sp. n. 
Adult female, length 33 lines. 
The general form and aspect of this spider is of the ordinary type. 
The cephalothorax is yellow-brown, darkest on the sides of the caput. The thorax has a distinct yellow-white 
marginal border, and a clear line of the same colour runs transversely across the fore part and sides of 
the caput below the eyes. The ocular area is suffused with yellowish-white, and the upper part of the 
caput has some streaks and marks of the same colour connecting the ocular area with a very distinctly 
marked, barbed, arrow-head, yellow-white patch covering the thoracic junction, the point of the arrow- 
head directed backwards. 
The eyes are in the ordinary position, small; the fore laterals only slightly the largest, and the intervals 
between the central pair of each row very little greater than that between each and the lateral eye next. 
to it of the same row. The height of the clypeus is more than half that of the facial space. 
The falces are yellowish-white, slightly marked near the base with yellow-brown. 
The legs are moderate in length and not very strong, 1, 2, 4, 3, of a dull yellowish hue tinged with brown. 
The anterior two-thirds of the metatarsi, as well as the tarsi, of the first and second pairs are dark 
reddish-brown, and the anterior extremity of the tibie of these two pairs is also slightly marked with 
red-brown. ‘The spines are few and weak, none apparently on the femora, two in front of the tibiz of 
the first pair. The rest in pairs beneath the metatarsi of the first and second pairs of legs. It is 
possible, however, that some spines may have been broken off. 
Mawille, labium, and sternum similar in colour to the legs. The sternum has a broad yellow-white angular 
border in front. 
The abdomen is somewhat pentagonal in form, narrow and truncated ; in front, much the broadest behind. It 
is of a yellow-brown hue, suffused more or less with whitish-yellow and at the centre of the fore extre- 
mity is a not well defined dark brown patch somewhat bifid behind. The underside has a brown longi- 
tudinal central band bordered laterally with whitish-yellow. The genital aperture is distinct and of 
characteristic form. 
Hab. Panama, Bugaba (Champion). 
Runcinia propinqua, sp. n. 
Adult female, length 23 to 3 lines. 
This species is of the ordinary form. 
The cephalothorax is brownish-yellow, with narrow lateral margins, a broadish lateral longitudinal reddish- 
brown band on each side, and a somewhat angular yellow-white marking at the thoracic junction, the 
angle directed backwards. A clearly marked whitish line runs transversely across the fore part and 
sides of the caput below the eyes; on the caput are two or three short black bristles. 
The eyes are normal in relative size and position; those of the posterior row are very nearly equidistant 
from each other, while the interval between the central pair of the anterior row is distinctly greater 
than that between each and the lateral eye next to it. The height of the clypeus is half that of the 
facial space. 
The falces are yellowish-white, with a large irregular yellow-brown patch at the base in front. 
The legs are rather short, strong, 2,1, 4,3. They are of a yellowish hue, the fore half of the tibie of the 
first and second pairs dark reddish-brown, and their metatarsi and tarsi of a lighter brown. The femora
