points converging towards each other. A moderately developed 

 connecting membrane present. Accessory plate brown, hairy. 

 First joint of penis dark brown ; second somewhat like that 

 of Sarcophaga froggatti, though more elongated. 



Described from one male, caught on decaying meat in 

 Brisbane, April 1921. 



This species is distingufshed irom all other Sarcophagids 

 known to us by the above-mentioned very prominent excres- 

 cences on the head. As all the remaining external characters 

 are of the ordinary Sarcophaga type, we are placing this form 

 in a new subgenus Parasarcophaga which may be provisionally 

 diagnosed as follows : — Male : General characters as in Sarco- 

 phaga ; but frontal stripe about three times the width of the 

 parafrontals whereas in the males of Sarcophaga it is seldom 

 more than twice ; frontal stripe developed into a very large 

 lobed prominence forming an arch around the mesofacial 

 plate. Type species, Parasarcophaga omega.
