160 Annals of the South African Museum. 



Adult male. Gephalothorax yellow, with a thin, central longitudinal 

 brown line, sometimes enlarged behind the eyes. 



Eyes small, subequal, those of the posterior row nearly equally 

 separated, the centrals rather nearer to each other than to the laterals, 

 the curve of the row very slight, and its convexity directed back- 

 wards. The central quadrangle is nearly square, its fore-side a little 

 the longest ; the height of the clypeus exceeds half that of the facial 

 space. The fore-central eyes are largest, and seated on a promi- 

 nence. A few spiniform tapering bristles on the caput are directed 

 forwards, the longest being exactly in the middle of the central 

 quadrangle of eyes. 



Legs moderately long, 1, 4, 2, 3 furnished with longish bristly 

 hairs of varied strength. Colour yellow, faintly annulated with 

 brownish. 



Palpi short, radial joint excessively so, similar in colour to the legs; 

 cubital joint with several long curved bristles in front ; digital joint 

 very large, oblong-oval, and the palpal organs rather simple, with an 

 obtuse prominence at their extremity on the outer side a strong, 

 black, tapering spine encircles the hinder portion, and another 

 is also curved in a circular form beneath the fore extremity. 



Maxilla, lab him, and sternum yellow, tinged with brown. 



Abdomen subglobiilar, furnished thinly with bristly hairs. Ground 

 colour dull luteous yellowish, with a longitudinal central strongly 

 and sharply dentated band, obtuse in front, enlarging to near the 

 middle and thence tapering to the spinners, this band is more or 

 less marked with white spots, and the dentations are formed on each 

 side by a distinct white lateral line more or less strongly margined 

 outside by a black stripe ; the sides are marked obliquely, but not 

 very regularly, with black and white. The under side has the fore- 

 part (including the plates of the spiracles) prominent, of a deep 

 black-brown, with a central white patch, and the spinners are on 

 a large blackish area ; nearly in front of the spinners is a con- 

 spicuous long transverse curved fold in the epidermis, in which 

 probably are concealed entrances to spiracular organs. 



The female resembles the male in colour and markings, but the 

 abdomen is more globular, and its central dentated band better 

 and more sharply denned, though with less black on its edges. A 

 series of examples would, however, probably show variations in 

 these respects.
