black -brown, llie abdomen dark grey, nearly black-brown 

 above and on the sides ; light reddish brown on the under- 

 side. 



The cephalothorax descends sharply behind the eye-space, 

 thence nearly straight to the cephalic fovea, where there is 

 anotlier rather sharp fall to the fovea, the thoracic part being 

 fairly flat, but rising moderately from the edges. 



The cephalic fovea is really straight and deep, but, being 

 enlarged at each end, appears to curve slightly both forward 

 and backwaid as looked at from behind or in front. 



The rastellum consists of two or three rows of rather thin 

 hardened bristles. 



The rear row of eyes is slightly recurved, the side eyes 

 being scarcely larger than the median, their narrow diameter 

 apart. The rear median are their long diameter fromi the 

 front median. The front median eyes, more than 1^ times 

 the long diameter of the rear eyes, are 1 diameter apart ; their 

 laterals, which are smaller, are almost vertically below them,

about the diameter of the latter distant. The distance be- 

 tween the outside edges of the front laterals only very slightly 

 exceeds the same measurement of the front median and rear 

 median, where it measures the same. Thus the outer edges 

 of the rear and front median and front lateral eyes lie on the 

 sides of a parallelogram. 



The greatest breadth of the eye-space is 1-65 millira., its 

 length 1*3. 



The lip is nearly twice as broad as long, hollowed in front, 

 and there are no spines on either lip or maxillae. 



The sternum is rather long, pear-shaped^ truncate, and 

 smallest in front ; the rear pair of sigillae moderately large, 

 not quite marginal. 



The third tarsal claw is quite small, without pectinations;
