TMARUS. 95 
Tmarus mundulus, sp. n. 
Adult female, length 13? lines. 
This spider bears a general resemblance to 7’. ineptus ; but the legs are shorter, their armature is different, 
the clypeus is higher, the markings on the cephalothorax and abdomen differ, and the form of the 
genital aperture is quite distinct. 
The cephalothorax is dark yellow-brown, paler behind the eyes, in a somewhat subtriangular form margined 
and bisected longitudinally with cream-yellow lines ; the hinder angle is produced backwards in a narrow 
cream-yellow band abruptly truncated just behind the thoracic indentation. The sides of the thorax are 
marked with converging cream-yellow lines; and the clypeus, which is distinctly higher than half the 
facial space, is much suffused with cream-ycllow. The surface is thinly furnished with not very strong 
prominent bristles. 
The eyes are like those of 7’, ineptus, excepting that the line formed by those of the fore central pair is distinctly 
shorter than that formed by each and the hind central eye on its side; in fact, the sides and hinder side 
of the figure formed by the four central eyes are equal, whereas in 7’. ineptus the fore side and sides of 
this figure are equal. 
The legs are short, yellow-brown, 2,1, 4,3; 2 and 1 scarcely appearing to differ in length, and 3 being a 
little shorter than 4. They are but faintly marked with whitish; and the spines under the tibie of the 
first and second pairs are four in number, in two pairs, and there are three pairs beneath the metatarsi. 
The falces are moderately long and strong, subconical, and about equal to the height of the facial space in 
length ; they are of a dark yellow-brown colour, marked more or less with ereamy-whitish in front. 
The palpi and maxille are similar in colour to the legs. 
The labium is dark yellow-brownish, and the sternum is of a slightly lighter hue. 
‘The abdomen is subpentagonal, much broader behind than in front, and has a smail subconical eminence at the 
top of the posterior slope, which last runs down nearly vertically to the spinners; its colour is whitish 
above and on the sides, mottled and marbled with yellow-brown; there is also a large, tolerably well 
defined yellow-brown patch on each side at the fore extremity and on each side just behind the subconical 
eminence. The underside has a broad central longitudinal dull yellowish-brown band from end to end. 
The upperside is covered sparingly with small prominent bristles. The genital aperture is small but of 
characteristic form. 
Hab. Panama, Bugaba (Champion). 
Tmarus corruptus, sp. n. 
Adult female, length 3 lines. 
The cephalothorax is of the ordinary form. The height of the clypeus slightly exceeds half that of the facial 
space. It is of a yellow-brown colour, marked with converging cream-white lines defining the caput and 
thoracic segments. The caput is much suffused with whitish, and towards the margins of the thorax there 
are also some irregular whitish mottlings. 
The eyes are normal in respect to their relative size, lateral tubercles, and general position. Those of the 
anterior row are separated by equal intervals. The hind central pair are nearer to each other than each 
is to the hind lateral eye on its side. The four centrals form nearly a rectangle whose anterior side is 
slightly shorter than the sides, and these last are a little shorter than the hinder side. 
The legs are moderately long and not very strong, 1,2, 4,3 ; there is little, if any, difference between the first 
and second pairs, but the third are a little longer than the fourth. They are of a pale yellow colour very 
slightly tinged with brown, and there is a broad whitish longitudinal band mottled with greyish-brown spots 
on the undersides. On the femora of the first and second pairs are, besides some others, three spines in a 
longitudinal row on the anterior side. There are also three pairs of spines beneath the tibiv of those 
two pairs of legs, and four pairs beneath the metatarsi, AJ} these spines spring trom minute blackish 
tubercles, and give the legs a spotted appearance. . 
The falces are moderate in length, not very strong, yellow-brown at the base, whitish beyond and on the 
inner side. 
The mawille are dull whitish ; the labium rather browner; and the sternum, which is more oval than in many 
other species of the genus, is yellowish-white thickly spotted with greyish-brown.
