XXVII. FrDivBaly, 1863. (Nlj., a non.sense name.) 

 The species of this genus resemble those of A,h>.nis in form, but 

 differ by having the front margin of thorax straight, the sutures 

 separating the si(h. pieces of prosternum wholly obliterated, and the 

 legs much longer'. From Xantlnnua the>- may be known bv the cyl- 

 indrical thorax and larger size. The males have the front tibi:e 

 curved inwards near the tip.
