kind of ring round the fore extremity of the metatarsus. Each tar- 

 sus ends with two claws and a scopula between them. 



The palpi are not very long, tolerably strong, and similar in colour 

 to the legs, except the digital joint, which is of a dark black reddish- 

 brown colour. The cubital joint is very short ; the radial is rather 

 less than double its length and has alongish, slightly sinuous, gradually 

 tapering, bluntish-pointed, deep-red-brown, shining apophysis from 

 the outer extremity, and a small rather prominent spur (or thorn- 

 like spine) near its extremity on the upperside : this joint is fur- 

 nished with slender bristles, of which those near the extremity of 

 the underside are largest and most closely grouped. The digital 

 joint is less narrow and drawn out than in many other species ; its 

 length is about that of the radial and digital joints together ; it is 

 prominent at the middle of the outer side ; the normal projection or 

 spur from the hinder extremity is of a corneous nature, rather long, 

 strong, a little directed outwards, crossing the outer radial apophy- 

 sis, tapering, sharp -pointed, and slightly bent inwards towards the 

 point, and of a deep blackish red-brown colour. The palpal organs 

 are of the ordinary form and structure, and have a blackish red- 

 brown, tapering spine issuing from near their fore extremity on the 

 outer side and curving round their hinder extremity. 



The falces are tolerably long, moderately strong, straight, slightly 

 projecting forwards, and of a deep rich red-brown colour. 



The maxilla are of the usual form ; yellow at the base, and red- 

 brown on the upper half; the labium is broadish oblong, very slightly 

 hollow at the apex, yellow near the base, and red-brown above ; 

 in the female the apex did not appear to be hollow, but straight. 



The sternum is yellow, clothed with fine pale hairs. 



The abdomen is much lighter before than behind, and projects a 

 good deal over the base of the cephalothorax. It is of a dull yel- 

 lowish-green colour, with a rather darker, elongate, tapering macula 

 on the fore half of the upperside ; this macula has two slightly pro- 

 minent points on each of the outer sides and is sharp-pointed behind ; 

 its margins are defined by pale cretaceous-looking spots ; and on each 

 side, not far from it, is a longitudinal row of three impressed spots ; 

 the surface of the abdomen is clothed, but not thickly, with pale 

 fine hairs. The spinners are short ; those of the superior pair are 

 very much smaller than the inferior ones, but longer by the length 

 of the small second joint. 



The female is similar to the male in colours and general charac- 

 ters ; but she has not the characteristic spiny armature of the hinder 

 metatarsi ; in fact the spines on the legs of the female are few and 

 inconspicuous. The genital aperture is small and simple, consisting 

 of a transverse slit within a somewhat quadrate external opening. 



Adults of both sexes were found by myself upon low plants in 

 the neighbourhood of Cairo in January 1864.
