Subfamily Ctets'Iziis'^. 



Three claws and a rastellum. Eyes on a more or less raised 

 prominence in the centre of the frontal area. 



Of the six groups into which M. Simon divides this subfamily 

 we have only three into which any of our genera can fall. 

 IdiojjecB — in which the front side-eyes are brought so far forward 

 as to be separated from the others ; Cyrlaucheniece and Nemesiece, 

 which M. Simon separates on the procurvedness or straightness 

 of the thoracic fovea, and these so overlap the borders that no 

 satisfactory dividing line between the groups can be drawn.

diameters distant from the rear side-eyes 2.
