second specimen, taken near Sydney, was found to agree with the Queensland 

 specimens and also with the descriptions. 



Description. — A straight process issues from the apex of each branch of the 

 upper forceps of the genitalia at the lower half. 



Hah. — New South Wales, Queensland and two female specimens in the Mac- 

 leay Museum from King George Sound, Western Australia. 



AsiLUS PELAGO Walker. (Text-fig. 5.) 



Asiliis pelago, Walker, List. Dipt. Brit. Mus., ii., 1849, p. 419; and vii., suppl. .3, 

 1855^ pp. 729, 731, and 735; Schiner, Verh. z.-b. Ges. Wien, xvii., 1867, 

 p. 400; Ricardo, Ann. Mag. Nat. Hist., (8), xi., 1913, p. 443. 



Description. — The attenuated portion of the upper forceps of the male 

 genitalia is short, slightly constricted subapically, and broadly rounded at the 

 apex; it is conspicuously deflected from the considerably arched basal portion; 

 the whole area is covered with a vestiture of short bristly appearance. 



Hah. — Western Australia: one male and one female from Perth; South .4us- 

 tralia: two males and four females in the Macleay Museum probably belong 

 here, but neither male specimen has the genitalia in sufSeiently good condition for 

 positive determination. 



AsiLus JIALLEOLUS Walker. (Text-flg. 6.)

 Asilus discutiens, Walker, Ins. Saund. Dipt., 1851, p. 135; Walker, List Dipt. 



Brit. Mus., vii., suppl. 3, 1855, pp. 729 and 736; Ricardo, Ann. Mag. Nat. 



Hist., (8), xi., 1913, p. 445; Wliite, Proc. Roy. Soc. Tas., 1916, p. 182. 

 Asilus unilineatus, Macquart, MS. name. 



Synoui/my. — The above synonymy is accepted on the authority of Miss 

 Ricardo. A. malleolus Walker takes precedence over A. discutiens Walker, under 

 which name the species has been well known liitherto. 



Description. — The upper forceps of the male genitalia are attenuated and 

 curve downwards; on the dorsal surface of the genitalia there is a hump ■^^■hich 

 partly conceals the lamella. 



Hah. — New South Wales. Miss Ricardo reports the species from "Van 

 Dieman's Land" which locality is usually taken to be Tasmania; there is, however, 

 a "Van Dieman" marked on some old maps in the north of Australia, and this 

 may be the locality of the many species recorded from Tasmania but only known 

 from the northern lialf of Australia.
