86 ARANEIDEA. 
meeting an oblique irregular stripe running laterally on each side from above the spinners forwards. The 
genital aperture is small and inconspicuous, but of characteristic form. 
Hab. Panama, Bugaba (Champion). 
Misumena pallida, sp. n. 
Adult female, length 34 lines. 
The cephalothorax is of a pale dull yellow-brown hue. The eye-tubercles and the rest of the ocular area 
white, and a strong, somewhat V-shaped white marking close to and on the thoracic junction. The upper 
surface is also furnished, but not thickly, with some longish prominent spine-like bristles. The clypeus is 
slightly less in length than half the facial space, and has a row of prominent bristles along its lower 
margin. 
The eyes are small, but in the normal position. Those of each of the fore and hinder rows respectively are 
equally separated one from another. The length of the trapezoid formed by the four central eyes is rather 
greater than its width behind, and the anterior side is rather shorter than the posterior. 
The falces are moderate in length and strength. Similar in colour to the cephalothorax, but mostly white in 
front. 
The legs are short, tolerably strong, similar to the cephalothorax in colour; the anterior sides of the femora 
and genua white. The metatarsi of the first and second pairs of legs have seven pairs of strongish, but not 
very long, spines beneath them ; the tibie of the first pair of legs have five pairs of spines, but those of the 
second only two pairs. The two posterior pairs of legs have a few very fine spines irregularly disposed. 
The mawille, labium, and sternum (as well as the under sides of the coxal and exinguinal joints of the legs) 
are more or less suffused with white. 
The abdomen is yellowish-white, large, of a somewhat pentagonal form, furnished with a few prominent black 
bristles on the upperside, and has some dusky markings on the hinder part, representing faintly the normal 
oblique bars or broken chevrons. The genital aperture is tolerably conspicuous and of characteristic form. 
flab. Panama, Veraguas ( Boucard). 
Misumena conjuncta, sp. n. 
Adult female, length 22 lines. 
The cephalothorax of this spider is reddish-yellow-brown, the sides and hinder part of the thorax yellow, and 
has a longish, somewhat X-shaped, cream-yellow marking near the thoracic junction. 
The eyes are small, but in the ordinary position, and on greyish tubercles: the interval between the two fore 
central eyes is slightly greater than that between each and the fore lateral next to it; the eyes of the 
posterior row are equidistant from each other. The four centrals form a square whose fore side is shorter 
than the rest. The height of the clypeus equals half that of the facial space. 
The falces are rather small, vertical, straight, and conical, and similar in colour to the cephalothorax. 
The legs are rather short, 1, 2, 4, 3, not very strong, the two anterior pairs of a reddish-yellow colour, with 
six pairs of spines beneath the metatarsi, and four pairs of spines beneath the tibie, all small, the former 
stronger ; on the femora are four spines. The two posterior pairs of legs are yellow, with a few irregularly. 
disposed very fine spines. 
The maaille, labium, and sternum are yellow. 
The abdomen is considerably broader towards the hinder part than in front, but not so pentagonal in form as in 
M. pascalis. It is of a dull yellow-brownish hue, marked on the sides forwards and towards the spinners 
with an irregular black band or elongate patch; on the hinder part of the upperside is a somewhat broken 
diamond-shaped patch, formed by slight black markings. The sides are also mottled with yellowish-white 
cretaceous spots. ‘The genital aperture is very small and inconspicuous, but of characteristic form. 
Hab. Panama, Veraguas (Boucard). 
This spider is nearly allied to I. pascalis, but differs in its characteristic markings, 
and also in the structure of the genital aperture.
