Genus Exoprosopa, Macquart. 



White's mayuiscript. — "Table of Australian Speci€s of 

 Exoprosopa. 



1. Abdomen shininp: blue. viargi)ticollis. Gray. 

 Abdomen black oi- brown. 2. 



2. Wings brown, with tips hyaline. stellifer, Walker. 

 Wings brown with ape.x very broadly hyaline and 



with large hyaline indentations below. 



adelaidica, Macquart. 

 Wings hyaline with the base, costa, and two oblique 



stripes brown. obliquifusciata, Macq. 



(unknown to me). 

 Exoprosopa laterimbuta. Bigot, I cannot at pi'esent place. 

 E. piinctipennis, Macquart, is a Hyperulonia. E. bicellata, 

 Macquart, is of doubtful position." 



Observations. — I am not certain if E. laterimbuta, Bigot, 

 as identified by myself, is not a colour variation of E. stelli- 

 fer, Walker; I have re-examined the specimens together 

 with the variation of E. stellifer, and failed to find a satis- 

 factory character other than the general black and brown 

 abdomens respectively, to distinguish these species. 



Exoprosopa marginicollis. Gray. 



Anthrax rnarginicollis, Gray, in Griflfith's Animal Kingdom, 

 XV., Ins. ii. 1883, p. 780; pi. cxxv., fig. G. 



This species, new to my list, was described without a 

 locality. Gray states that it "has the thorax green with a 

 "white line on each side; the body blue, the wings diaphanous 

 "with the anterior part and base black." In the Macleay 

 Museum there are several specimens which are undoubtedly 

 this species, but all arc cntii-ely metallic blue, except one, 

 and that has a metallic green abdomen showing that either 

 the blue and green are interchangeable, or the latter is a dis- 

 coloration.
