Genus Sungenia,!'' gen. nov. 



Allied to Hogg's genera Chenistonia and Del-ana by the tibial apophysis 

 on leg i. terminating in a powerful spine, but dilfering from the former 

 by the thoracic fovea being strongly pi'ocurved instead of straight, and 

 from the latter in having the posterior sternal sigilla marginal instead 

 of being away from the margin, each of which are major features from 

 a generic standpoint. The eyes are mounted upon a tubercle, the area 

 of which is broader than long, they are distributed over two rows of four 

 each, the front one being procurved, and the rear recurved ; the anterior 

 and lateral eyes are of equal size and largest of the group ; anterior 

 medians round ; rear medians smallest of the group.
