*The following three genera are not sufficiently well defined to place in this synopsis. In 

 color and structural characters they are closely related to Cynomyia from which they may be 

 distinguished as follows. Catapicephala Macq.. represented by the species C. splendens from 

 Java, has the setse on the facial ridges rising to the base of the antennas and has median margi- 

 nal macrochastas on the abdominal segments two to four: Blephari enema Macq., represented by 

 B. splendens from Venezuela has bare genae, oral setae not ascending ; tibiK villose; claws short 

 in both sexes; Sarconesia Bigot with the species 5. chlorogaster from Chile, setose genas; legs 

 slender, not villose; claws of the mael elongate.
