joining front margins of laterals will bisect the centrals) ; cen- 

 trals smallest of all, about equidistant from posterior centrals 

 and anterior laterals, their own interval less. 



Clypeus higher than ocular area, convex. 



Stermim ('8 mm. by '6 mm.) light brown, produced between 

 the posterior coxae. 



Legs dull yellow, clothed with short hairs ; femora unarmed ; 

 patellae with one weak spine ; tibiae with two spines above, one 

 towards the apex, the other near the base ; protarsi unarmed. 



Ahdomen pale olive green without pattern, clothed with short 

 hairs. 



Falces ('6 mm.) stout, and convex at the base, striate extern- 

 ally, slightly divergent, and provided with a conical apophysis 

 on the inner face pointing forwards and inwards, truncate, and 

 bearing a fine short bristle. 



Palpus. Humeral joint four times the length of cubital, which 

 is two-thirds of the radial : cubital joint bears a short sinuous 

 spine above : radial joint as broad at its outer extremity as long, 

 showing three processes clasping the digital joint, two above and 

 one beneath, the latter acute ; the inner above also acute, its 

 point curved slightly outwards from the digital joint. Digital 

 joint hardly broader than the radial, very convex, bearing a 

 strong spine about the middle and two others not quite so long 

 at its extremity. Palpal organs rather complex : the terminal 

 third is a membranous bulb ; from its base on the inner side 

 springs a red-brown bandlike process clasping the bulb and pro- 

 jecting beyond it, denticulate along its truncate extremity, and 

 bearing two or three small dark projections ; from the outer side 

 of the base a most characteristic process, — almost flat but slightly 

 keeled externally, narrowing to its blunt extremity, the inner 

 edge denticulate, — pointing forwards and outwards, nearly reach- 

 ing the extremity of the joint. At the base of the palpal organs 

 is a dark-brown hooked process with a blunt point. 



'N. A single adult male was taken from under a stone on the 

 coast near Whitley, Oct. 23, 1895. It is nearly allied to Tmeticus 

 simplex, F. Cb., and Tm. dentichelis, Sim., but the denticulate 

 process of the palpal organs and the form of the radial joint of
