 ber to April.

Synonymy. — A. fusicornis, Macquart, is the female of 

 A. gibbicornis, Macquart; specimens have been taken in 

 copula on many occasions, and thus the sex relationship has 

 been established. Specimens in the Macleay Museum were 

 labelled with their sexes denoted, and the label conveying the 

 synonymy was probably written by Skuse or Masters. 



The description of A. inappendiculatus, Bigot, was 

 probably taken from a female — not a male as stated in the 

 description — of this species. 



Hab. — New South Wales; Sydney. This is the first 

 species of Bombylid to appear in the spring, and it continues 

 on the wing through the summer ; it occurs everywhere where 

 wild flowers are abundant, and at times twenty or thirty 

 specimens can be taken with one sweep of the net, and in- 

 deed sometimes they are so abundant that they continuously 

 divert one's attention from other insects.
