 Synonymy. — White placed Berts quinquecella, Mac- 

 quart, amongst his doubtful speci s, but Macquart's illus- 

 tration was undoubtedly intended u r present this species, 

 as the inilation of th< costa, although shown small in the 

 drawing, Leaves no doubt concerning the generic position, 

 and the locality given is Tasmania. 



Amendments: — In Macquart's description and illus- 

 trations, the scutellum is describ d with four jpines, and 

 corr ctly illustrated with eight, and the five posterior- 

 cells described arc erroneously drawn as four. Allowing 

 for these corrections, Macquart ption and drawing 



conform to this species.
