« Th(> following genera of this family have not been seen by me; and being unable 

 to ascertain, from published descriptions, the essential features of their external struc- 

 ture (as for example, the character of tarsal scutellation and degree of cohesion between 

 anterior toes), I am unable to properly place and define them in the " Key:"
