PALYADINiE. 



This subfamily is tropical, the two species of our fauna occurring- 

 only in the southern part of Florida. They are characteristically 

 and peculiarly marked by the absence of the frenulum, which feature 

 may warrant family distinction. The Geon)etrid character of the 

 family is shown by the strongly marked angle at base of vein 8 in 

 the hind wings.

MECOCERATIN^. 



The Mecoceratin£B have scarcely any representatives in our fauna, 

 and this subfamily, while tropical, has few representatives in any 

 part of the world. They are easily recognised by the extreme length 

 and slenderness of the antennae and^legs, which in them becomes a
