ARGYRODES. 259 
dull brownish hue speckled with whitish points, and the middle of the underside is marked with larger 
silvery spots on a black ground. The genital aperture and processes are characteristic, of a deep blackish- 
brown, and, with the spiracular plates, are comprised in a quadrate area surrounded with a pale dull 
whitish margin. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
Argyrodes aurea. 
Argyrodes aurea, Camb, antea, p. 207, t. 26. figg. 1, 1 a-c. 
The female only of this species was described and figured (vide 1. c. supra). 
Adult male, length to extremity of abdomen slightly over 1 line, to spinners ? of a line. 
Cephalothorax of normal form, colour dark yellow-brown. The height of the clypeus exceeds half that of the 
facial space; it is strongly indented just below the fore-central eyes, and the lower part projects in a 
prominent obtuse beak-like form over the base of the falces. 
Eyes differing from those of the female slightly, the central quadrangle forming a square. 
Legs 1, 2,4, 3, those of the first and second pairs long, and much stronger than the rest, colour reddish-yellow- 
brown ; the tarsi and metatarsi of the first and second pairs yellowish, the latter suffused with brownish 
at the anterior extremity ; the third and fourth pairs have half or more of the femora at the hinder end 
yellow, the rest yellowish-brown, the genus brown ; the tibie and metatarsi of the third pair brown, with 
an annulus of yellowish at the hinder extremity of the metatarsi ; the fore half of the tibia of the fourth 
pair is brown, the metatarsi and tarsi brownish-yellow. 
Palpi short, brownish-yellow, deepening to dark yellow-brown on the digital joint ; cubital joint bent, clavate ; 
radial joint produced at its extremity on the outer side. Digital joints oval, of moderate size, their outer 
sides facing inwards. Palpal organs simple, consisting chiefly of a large, convex, roundish-oval, corneous 
lobe. 
Falces long, strong, straight, and projecting forwards ; colour like that of the cephalothorax. 
Mazille and labium normal, the former dark yellow-brown, the latter black-brown. 
Sternum subtriangular, convex, the posterior extremity produced between the coxe of the fourth pair of legs, 
and eminences opposite the insertion of the legs. Colour shining black-brown. 
Abdomen short-oval, elevated and produced behind ; a short, obtuse, subconical, central prominence about the 
middle of the hinder part, and a little in front of this on each side the abdomen is also slightly prominent. 
The colour of the abdomen is yellow-brown, pretty thickly covered with silvery-metallic spots, which are 
placed (on the upperside) chiefly on each side of the median line, leaving a dark blackish-brown space 
between, broadest in front, narrow behind ; the hinder extremity of the abdomen is marked on each side 
with a black spot, close in front of which is an intensely bright silver one, also a little way above the 
spinners are two round intensely brilliant silver spots in a transverse line, margined above with black. 
The region of the sexual opening is rather prominent and shining dark blackish-brown. Spinners placed 
in a somewhat socket-like subconical prominence. 
Although not possessing the golden tinge of the female (described J. c. supra), I think this spider is of the 
game species. 
Hab. Guatemata (Sarg). 
Argyrodes linguata, sp. n. 
Adult male, length 13 lines. 
Cephalothorax of ordinary general form, colour dull yellow-brown, marked with darker lines and strie; the 
form of the clypeus (which greatly exceeds in height half that of the facial space) is very characteristic. 
The whole clypeus forms a large circular prominence, beginning immediately below the eyes ; a little way 
below them is a strong deep transverse indentation or excavation, oval at each end, and with a somewhat 
rounded, obtuse, lip-like projection at the middle of the upper edge furnished with coarse hairs; from 
beneath this extends a kind of tongue-like process over the lower edge (or lip) of the excavation, and 
thence the clypeus projects roundly and very prominently over the base of the falces.
