 of both sexes distinctly separated; dorsal surface of 

 the squamula thoracalis with black hairs; two post 

 sutural intraalar macrochaetae. 



j. Hypopygium of the male large, with a pair of slightly 

 curved forceps whose ends are concealed in a longi- 

 tudinal slit in the fifth ventral sclerite; third posterior 

 inner dorso-central (acrostichal) macrochaetae absent; 

 anterior intraalar rarely present ; abdomen usually not 

 pollinose; the second segment without median marginal 

 macrochaetae; face yellow. C. mortuorum, cadaverina, 

 and related species. Both hemispheres.

. Three pairs of posterior inner dorsocentrals (acrostichals) 

 present; second abdominal segment with a row of

*The following three genera are not sufficiently well denned 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 setae on the facial ridges rising to the base of the antennas and has median margi- 

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

 B. splendens from Venezuela has bare genas, oral setas not ascending; tibiae villose; claws short 

 in both sexes; Sar'onesia Bigot with the species 5. chlorogaster from Chile, setose genae; legs 

 slender, not villose; claws of the mael elongate.
