DICTYNA.—TRICLARIA. 173 
Hab. Mexico, Chilpancingo in Guerrero (f/f, H. Smith). 
This is the largest spider of the genus I have yet seen. 
TRICLARIA, C. L. Koch. 
Triclaria habilis, sp. n. 
Adult male, length 4—43 lines. 
Cephalothorax yellow-brown, with an olive-greenish tinge. A longitudinal darker yellow-brown band 
(dentated on its outer margin) on each side of the median line, and also a narrow, dentated, marginal 
band on each side; the interval between these is a strongly zigzag pale yellow-brown submarginal stripe ; 
immediately behind the eyes are four short dark yellow-brown parallel dashes or short lines, followed by 
a transverse, somewhat oblong patch of the same joining in with the thoracic indentation. Ocular area 
dark, nearly black, clothed with grey hairs, 
Eyes normal in general position and size. The quadrangle of the four centrals is distinctly broader than long, 
and its fore-side is shortest. The interval between the hind-central pair is less than two diameters, each 
being at least two from the hind-lateral eye on its side. The fore-central pair are nearly a diameter’s 
distance from each other, and about half the distance from the fore-laterals. Each hind-lateral eye is 
placed on the outer side of a strong tubercular prominence. The height of the clypeus is equal to a little 
more than the diameter of one of the hind-central eyes, being less than one-third of the height of the 
facial space. 
Legs long, moderate in strength, 2, 4, 1, 3, similar to the cephalothorax in colour, more or less annulated with 
darker yellow-brown on the femora and tibiz, furnished with hairs and longish slender spines, without 
scopula ; the superior terminal tarsal claws have five teeth on the inner side of the basal half, the inferior 
claw is small, In this spider the tarsal claws appear to spring from a supernumerary (or claw) joint 
of rather unusual size. This may have also been the case with the next species (7. extensa, p. 174), 
but if so the density of the hairy clothing concealed it. The tarsi are very long, cylindric, and 
characteristically elastic, those of the fourth pair distinctly longest. 
Palpi similar to the legs in colour, marked, but not very definitely, with dark yellow-brown; the digital joints 
are also dark yellow-brown. The humeral joint has afew short strong spines on the upperside; the 
cubital joint is somewhat clavate, rather shorter than the radial, and has a long, strong, tapering spine at 
its fore extremity on the upperside. The radial joint has two or three similar spines on its upper surface, 
with numerous long, pale, coarse, grey hairs on the fore part and outer sides; it has also a strong somewhat 
angular prominence at its anterior extremity beneath, and a strongish but not very long, dark reddish- 
brown, flattened truncated apophysis, with a strong spiny point behind near its fore extremity on the outer 
side; and in front of it, close to the hinder part of the palpal organs, is another, less broad, yellow-brown 
apophysis, bifid at its extremity. The digital joint is about one-fourth longer than the radial, densely clothed 
with hairs, and has three (or more ?) elongate-oval, strong, tapering spines towards its base on the inner 
side. The palpal organs are simple; they consist mainly of some strong corneous lobes and spiny projec- 
tions, and reach to about one-third of the length of the joint from its fore end. 
The falces are moderately long, strong, greatly and roundly prominent in front, the profile forming a very 
strong curve. Colour yellow, suffused with a darker hue on the outer sides. Fangs strong, curved; at 
the extremity of the falx on the inner margin are two strong teeth of equal or nearly equal length, 
meeting the fang when closed. 
Mawille and labiwm normal. Colour yellow or pale yellow-brown, the latter suffused with darker yellow- 
brown towards the base. 
Sternum as broad as long, i. ¢. not reckoning the posterior extremity, which is considerably produced into a 
tapering but obtuse point between the coxz of the fourth pair of legs. Colour pale yellow. 
Abdomen short-oval, somewhat truncated before. Colour dark blackish-brown above, with a broad yellow- 
brown central longitudinal marking, pointed at its hinder extremity; on the fore half this has a black- 
brown margin edged outside again with pale yellow-brown, and is followed towards the spinners by a 
series of three somewhat curved but broken transverse pale yellow-brown lines; the sides and underside 
are pale yellow-brown, the former marked with fine, but irregularly-parallel longitudinal blackish strise
