Gen. Tetragnatlia, Latr. 



TetragnatJia t'jpica, sp. nov. Plate XYII., figs. G and 7. 



Female.— Cei:)\i.-th., long, 4-5 ; broad, 2-8. Abd., long, 10 ; 

 broad, 4. Legs, 1, 2, 4, 3 = 34, 23-5, 22-5, 10 nnn. 



Cephalotliorax light sienna-brown ; median band broad, 

 tapers from occiput to base of thorax, chocolate-brown ; 

 lateral margins and striae similar colour ; nearly glabrous ; 

 oval, lateral constriction at caput slight ; pars cephalica de- 

 pressedly convex ; ovate central indentation ; eye-eminence 

 moderate, somewhat conical ; facial index rather more than 

 one-half breadth of pars thoracica ; latter depressed, displtiys 

 two deep narrow-ovate indentations, apices converge forwards 

 to limit of caput ; radial stritc faint ; contour of profile slopes 

 moderately backwards to thoracic indentation, displays pos- 

 teriorly an obtuse conical prominence ; cUjpeus inclined 

 perceptibly inwards, depth about equal to diameter of a fore- 

 central eye. 



Posterior and anterior rows of eijes moderately recurved, 

 former rather the shortest ; median eyes of hind row percep- 

 tibly closer to one another than they are to laterals ; rather 

 smaller than fore-centrals, visibly larger than side-eyes of 

 their own line ; anterior median pair seated obliquely on an 

 eminence, perceptibly more than an eye's breadth apart, rather 

 more than that interval from hind pair, with which they form 

 a trapezoid, narrowest in front ; lateral eyes posited on low, 

 black, tubercular eminences, interval between them nearly 

 equals that between fore- and hind-centrals ; posterior pair 

 visibly the largest. 



Legs fulvous ; slender ; hairs fine, sparse, yellowish ; few 

 bristle-like spines on femora, patella', tibia?, and metatarsi; 

 superior tarsal claws moderately curved — first pair, 13 close 

 comb-teeth, increasing somewhat in size ; inferior claw rather 

 long and strong, 2 close teeth. 



Palpi colour and armature of legs ; palpal claw well- 

 curved, 15 comb-teeth, increasing in size. 



Falces yellow mahogany-colour; equal cephalothorax in 

 length ; cylindrical, strongly pronected, divergent, beneath 

 fore-extremity on outer side is a rather strong tooth-like pro- 

 cess ; 9 teeth in superior row, increasing somewhat in size, 

 third tooth from fore-end rather the longest ; inferior row 11 

 teeth, second, third, and fourth from apex rather the weakest. 



Maxillce yellowish-brown ; long, linear, apex rounded and 

 somewhat enlarged on superior side, moderately divergent. 



Labium chocolate-brown ; everted apex yellowish ; conical, 

 base collar-like ; more than one-third length of maxilla?. 



Sternum yellowish-bro\Yn ; cordate.
