The male has its cephalothorax smooth and shining, with the 

 head strongly elevated and forming a protuberance, which, when 

 viewed in profile, is almost double as long at the base as it is high, 

 slightly convex above, sloping abruptly and convexly both before and 

 behind (more abruptly before than behind). The head has a large and 

 deep depression on each side, the bottom of which forms a furrow, 

 extending from the lateral eyes directly backwards along the base of 

 the cephalic eminence. The lower part of the face forms a narrow 

 projecting ledge, in front of the upper part which carries the poste- 

 rior centre eyes. This upper part or front of the cephalic eminence 

 is hairy, half as broad again as it is high, with the upper angles 

 rounded, and somewhat narrower or slightly constricted below. The 

 posterior centre eyes are separated by an interval at least double as 

 great as their diameter: the anterior row of eyes is straight, its la- 

 teral eyes stand at very nearly a diameter's distance from the small, 

 almost contiguous centre eyes. The area of the centre eyes is half 

 as long again as it is broad behind; the height of the clypeus is 

 about equal to the length of that area and to the length of the an- 

 terior row of eyes. The upper part of the tibial joint's apex, inward,
