Thorax. Brownish black where denuded in centre, elsewhere 

 covered with golden tomentum, and with scattered depressed 

 golden pubescence and long semi-erect brownish hairs, fringed 

 posteriorly at sides with long, somewhat scanty, golden hairs. 

 Pleurae with tufts of long golden hair. Scutellum Mars yellow 

 with golden tomentum. 



Abdomen. Mars yellow more or less densely clothed except 

 where abraded with fine, depressed, golden pubescence, under 

 surface Mars yellow. 



Legs. Similar in colour; femora rather lighter. 



Wings clear, slightly tinged yellowish along the fore border 

 and at base, stigma yellowish, first posterior cell closed; no 

 appendix present. 



A brilliantly coloured golden species not resembling any other 

 Australian form. Three specimens only were taken, two at 

 Kendall in the bush on December 3rd, and one at Lome about 

 two miles distant on December 17th. Eyes a bright metallic

Erephopsis quadrimacula Walker. 



List. Dipt., Part 1, p. 138 (1848) ; Ric., I.e., p. 117. 



Specimens of a large maculate winged species agree with the 

 description of E. quadrimacula, and pending confirmation from 

 the British Museum have been labelled as such. Specimens 

 were plentiful from November 19th to December 23rd. It was 

 found in the bush and the dairies, and was easy to feed on 

 experimental calves. 



Erephopsis coxtigua Walker. 



List. Dipt., Part 1, p. 138 (1848) ; Ric, I.e., p. 116. 



This species has also been provisionally identified, our speci- 

 mens agreeing with Walker's description. No field notes are 

 available of this species as in the field they were confused with 

 E. quadrimacula, and the notes given above should apply to both 

 species . 



Erephopsis concolor Walker. 



Dipt., Saunders, Part 1, p. 14 (1850) ; Ric, I.e., p. 118. 



This species, which has been identified on comparison with 

 Walker's type, has been placed in Erephopsis as in our series 

 the first posterior cell is more frequently closed than open, and
