 bounded by high sharp walls, between which and the lateral margins 

 is a broad and shallow trough; furcula consisting of a pair of slight 

 triangular lobes broader than long, separated by their own breadth; 

 cerci very stout, large and broad, laminate, externally convex, the 

 basal half narrowing gently, beyond the middle at once expanding into 

 two lobes : an upper, nearly as long as the basal half of the cerci, directed 

 upward and backward, forming an ovate pad; and a lower, brief, tri- 

 angular denticle, broader than long, the apical margin more or less 

 distinctly emargiiiate below between them; infracercal plates shorter 

 than the supraanal plate, but expanding a little laterally beyond its
