50 ARANEIDEA. 
The legs are moderately strong, not very long; their relative length, 1, 2, 4,3; they are armed with bristles 
and spines, most of which are on the metatarsi and tarsi. 
The palpi are similar in colour and armature to the legs. 
The falces are strong and vertical. 
The maxille and labium are similar to the falces in colour ; the former are sometimes suffused in the middle 
with dusky ; the latter is pointed at the apex and its lower half is black. 
The sternum is blackish, marked with six yellow raised spots on the margin opposite to the insertions of the 
three anterior pairs of legs, and bisected longitudinally with a yellow stripe, the stripe strongly constricted 
near the middle, in some examples broken into two or three spots of different size and form. 
The abdomen is large, somewhat oblong-oval in form, of a cream-white colour all over, clothed with grey 
pubescence and destitute of any markings, at any rate in the preserved specimens, but a little suffused 
with yellow-brown on the sides. On the fore part, towards but not close to the foré margin, are four 
distinct, though not very large, somewhat tubercular subconical eminences forming a square; the hinder 
extremity is more or less produced and projects considerably over the spinners, and the caudiform portion 
is cleft deeply at the end into two large obtusely pointed lobes; the underside, embracing the spinners on 
each side, is white. The spinners are short, compact, and of a pale yellow-brown hue. The genital 
process is of moderate size, prominent, of characteristic form, and has its hinder portion recurved in a 
kind of short epigyne. 
Hab. GuatTEeMaa, between Dolores and Chapallal, and between Dolores and Chisec 
(Sarg). 
An example found by Mr. Sarg between Dolores and Chapallal had the abdomen 
(at the time it was taken) of “a creamy-yellow-pink hue.” Others were found between 
Chisec and Dolores. 
This spider apparently belongs to the L. anseripes group. 
Cyclosa lacerta, sp. n. 
Adult male, length 12 line. 
Cephalothoraw broad and rounded behind, moderately convex above. Caput comparatively narrow, and its 
fore part sloping downwards; the colour of the cephalothorax is deep bistre-brown, paler in the ocular 
region, and the thoracic portion is narrowly but distinctly margined with dull yellow. 
The eyes are on black spots and in the usual position, forming a square whose hinder side is shortest; the 
anterior pair of the central group are apparently rather larger than the posterior pair—they are seated 
on a prominent tubercular projection, and also form a considerably longer line than the posterior pair, the 
eyes of which are of a pearly colour, and separated from each other by a very narrow interval. 
The falces are moderately long, rather slender, and directed backwards, being dark brown in colour, with 
paler extremities. 
The legs are moderate in length and strength, 1, 2,4, 3, 2 and 4 differing little, if anything at all. The 
colour of the femora of the first pair is deep brown like the cephalothorax, the other femora are similar but 
pale yellowish at their base, the remaining joints are yellow-brown, or yellowish, annulated with darker 
yellow-brown. They are clothed with short hairs and some spines, the most conspicuous of which are 
on the tibie of the first and second pairs. The surface of the tibie of these pairs is roughened with 
minute granular tubercles. 
The palpi are short; a strong, tapering, black, prominent bristle issues from the fore extremity of the cubital 
joint. The digital joint has a curved process at its base on the outer side. The palpal bulb is large, 
the palpal organs very prominent, highly developed and complex, with several characteristic lobes and 
corneous processes. 
The maaille and labium are dark black-brown, edged at their extremities with yellowish. 
The sternum is similar to the cephalothorax in colour, and is margined with seven yellowish-white spots, three 
on each side, and one at the pointed posterior extremity.
