Eyes in normal position, very nearly equal ; all pearly white, on 

 black spots ; the convexity of the slight curve of the posterior row 

 directed outwards, that of the anterior forwards. Those of the 

 posterior row equally separated by more than a diameter ; the 

 central quadrangle forms a square ; a few longish bristles on 

 the caput directed forwards ; of these the two longest are in a 

 transverse line at the middle of the central quadrangle. The height 

 of the clypeus is two-thirds of the facial space. 



Legs moderately long, 1, 4, 2, 3 slender, furnished with hairs and 

 slender bristles, a very few almost spiniform ; colour like that of the 

 eephalothorax, the femora and tibiae of the fourth pair suffused with 

 dull brown, as also less strongly those of the other legs. 



Falces moderately long and strong, normal ; these with the 

 Maxilla, Labium, and Sternum (which last is broadly and somewhat 

 roundly truncated at its hinder extremity) are pale yellow. 



Abdomen large, almost globular ; projecting much over the 

 eephalothorax ; of a dull orange-yellow colour, marked faintly with 

 a white longitudinal central line from which two or three slightly 

 oblique lateral ones issue on each side ; the sides also have two or 

 three similar oblique lines, and one encircles the fore extremity on 

 the upper side. The genital aperture is of very characteristic form. 

 The lines on the abdomen are formed by minute white spots. It is 

 possible that other examples, when found, will exhibit some modifica- 

 tion in colours and markings. In that case the form of the genital 

 aperture will become all important.

Adult male, length 1-]- lines. 



Adult female, li to If lines. 



Cephalothorax pale yellow, marked rather diffusely and indistinctly 

 with yellow-brown along the converging lines of the normal indenta- 

 tions and the fore part of the caput. The height of the clypeus is 

 nearly two-thirds of the facial space. 



Eyes normal ; sub-equal, fore-centrals smallest ; all pearly-greyish 

 white ; the slight curve of the posterior row directed backwards, that 

 of the anterior row forwards. The two rows are very nearly of equal 

 length, anterior slightly shortest. The interval between the hind- 

 centrals a little larger than that between each and the hind-lateral 

 next to it. The fore-centrals are smallest. The central quadrangle 

 is a square with its fore side rather the shortest. The prominence
