382 DIPTERA OP AUSTRALIA, 



Mr. Helms obtained specimens of this species at Dunoon, Rich- 

 mond River, N.S.W., in March and April. 



2. Antennae in the ^ decorated with long hairs on the upper 

 side. 



52. DiPLOSIS VIOLACEA, Sk. 



D. violacea, Sk., I.e., p. 101. 



I have found this species in large numbers about Sydney in the 

 months December to April. Mr. Helms obtained specimens at 

 Dunoon, Richmond River, N.S.W., in April. 



55. DiPLOSIS NEGOTIOSA, Sk. 



D. negotiosa, Sk., I.e., p. 104; D. fallax, Sk., (^), I.e., p. 85. 



After comparing numerous additional specimens D. fallax is 

 considered identical with D. negotiosa. This appears to be one of 

 our commonest species. 



56. DiPLOSIS ACTIOSA, Sk. 



D. actiosa, Sk., I.e., p. 105. 



Some specimens, darker coloured than those from which this 

 species was originally described, were obtained by me at the 

 Quarantine Grounds, North Head, near Sydney, in September.

(J. — Length of antennte 0*105 inch ... 2'67 millimetres. 



Expanse of wings 0-120 x 0-055 ... 3-04 x 1-39

This species was described from a single ^ si)ecimen ; another 

 specimen recently obtained appears to be a ^, and conforms with 

 my description in everything but the size. The antennae are 

 2- + 12-iointed, nearly as long as the entire body.
