1 This family needs thorough revision ; nothing has been done to bring the 

 genera together in a broad way since Stal's work was pubhshed in 1866. Distant, 

 Kirkaldy and others have tabulated the genera of restricted areas, but have not 

 compared them with those found elsewhere. 



The genera Eurynomeus and Gythna are closely allied, and E. granulatus is 

 somewhat intermediate, so that it is possible that they will have to be combined. 

 In Cythna, the areolets at the apex of the vertex are visible in dorsal view, 

 whereas in Eurynomeus they are more frontal and not visible.
