142 ARANEIDEA. 
a rather larger spider, and the genital aperture of the female is of a distinct form. The form also of the 
radial apophysis of the male palpus is different, the palpus itself is rather shorter in proportion, and’ the 
digital joint smaller. 
Hab. Panama, Bugaba (Champion). 
Oxyopeidon letum, sp. n. ; 
Adult female, length rather over 23 lines. . 
The cephalothorax is broader in proportion to its length than that of 0. molestum, and the clypeus is rather 
prominent below. The cephalothorax is yellow-brown, the ocular area reddish; it is clothed with 
squamose grey hairs, of which one or more conspicuous lines mark out the ocular area and the limits of 
the clypeus ; the height of the latter appears to be nearly about half that of the facial space. 
The eyes occupy a wider, as well as a rather flatter, area than in either O. molestum or O. subfacile; the interval 
between the two posterior eyes is equal to, even if not exceeding, double that between each and the 
lateral eye next to it, and the two minute anteriors are almost, when looked at from on a level in front, 
in a line with the two large eyes near them, so that a line drawn to touch the lower margins of the two 
large eyes would run very nearly through the centre of the small ones. The absolute, as well as relative, 
size of these two large eyes appears to be greater than in either of the species above described. 
Falces similar in colour and clothing to the cephalothorax. 
Legs yellow, very slightly indeed tinged with brown near the middle of the femora. 
Abdomen dull brownish-yellow above, with two rather converging longitudinal black lines near the middle, 
and a distinct black patch on each side a little above the spinners, from which to a little way upwards is 
a series of short, indistinct, subangular, brownish lines or chevrons ; there are also some other indistinct 
yellow-brown markings near the middle and on the sides. The abdomen is clothed with squamose grey 
hairs, The underside is dusky brown, and the genital aperture is simple but of characteristic form. 
Hab. Mexico, Dos Caminos, on the rodd from Chilpancingo to Acapulco, alt. 2700 
feet (H. H. Smith). 
In the position of the eyes this species approaches 0. facile, but it is very much 
smaller and differs in other respects. 
Oxyopeidon difficile, sp. n. 
Adult female, length 3 lines. 
Cephalothorax yellow-brown, clothed with short grey hairs; the sides are marked with a broken marginal line 
and irregular converging lines of blackish hue. 
Eyes of hind-central pair nearly double the distance apart that each is from the hind-lateral eye on its side; 
the line of the two small anterior eyes is distinctly below that drawn between the lower margins of the 
two large eyes nearest to them. The height of the clypeus, which is straight and slopes a little forwards, 
is equal to half that of the facial space. 
Legs moderately long, slender, with the usual spiny armature. Colour brownish-yellow, an imperfect band 
across the middle of the femora, the posterior extremities of the tibix blackish ; the metatarsi of the 
third and fourth pairs also indistinctly annulated with blackish. . 
Abdomen yellowish-brown, clothed with short whitish and other hairs; the upperside has an irregular black 
bar along the middle, followed by some irregular black angular bars or chevrons above the spinners, and 
some irregular black patches or markings on the sides; the underside has a broad longitudinal dark 
brown band. The genital aperture is of simple but characteristic form. 
The falces are yellow-brown, tolerably long, strong, clothed with short grey hairs. 
The maville, labium, and sternum are dull yellow, the maxille and labium tinged with brown.
