Two subfamilies have been defined, separated by the number of joints in the 



tarsi. 



TABLE OF SUBFAMILIES. 



Tarsi 5-jointed Subfamily I. Gonatocerinje. 



Tarsi 4-jointed Subfamily II. Mymaein^. 



Subfamily I. Gonatocerin^. 



The subfamily is easily recognized by the longer tarsi which are always 5-jointed, 

 never 4-jointed. 



Two tribes may be distinguished by the following simple characters :
