colour, black-haired, with the exception of the abdomen, which is 

 greyish black with a silky gloss: it has a paler central streak or 

 spot on the back in front, and the area before the rima genitalis is 

 yellowish. The tibial joint of the palpus is somewhat shorter than 

 the patellar, rather shorter than its own breadth, towards the apex 

 gradually broader, with a strongly projecting corner on the under 

 side of the apex and a very little, scarcely perceptible tooth at the 

 extremity of the outer side. The lamina is truncated at the base, 

 where it is scarcely broader than the tibial joint at its apex , as long 

 as the patellar and tibial joints together, and as broad as the patella 

 of the 2 nd pair of legs. The bulbus is very simple, with a little 

 protuberance at the base on the under side and with a couple of fine 

 points or hooks at its extremity (?).

1) In this genus the posterior row of eyes is in general curved backwards 

 by the lateral eyes being placed beliind the central. That the lateral eyes are 

 placed lower than the central, has of course no influence on the curvature of the 

 series as seen from above, but only if it is seen from before. In this work 

 the curvature of the posterior row is always determined as seen from above, and 

 that of the front row as seen from before ; the series is said to be curved forwards 

 when its convexity is directed backwards, and vice versa.
