592 Miss G. Ricardo — A Revision of 



Macquart^s type was recorded from New South Wales, 

 and he notes another specimen as from Brazil. 



Macquart^s type (?) and three other female specimens, 

 all varying in size, were seen by me in the Paris Museum. 

 In the type the third segment is almost wholly dark, in the 

 other specimens only dark on the anterior border as in the 

 specimens in the British Museum. Apex of abdomen 

 furnished with circlet of spines. 



Walker's three types were described from unknown 

 localities. 



There are specimens in the Brit. Mus. Coll. from Aus- 

 tralia, New South Wales. Mr. Froggatt records a specimen 

 from Mittagong, New South Wales. 



This species cannot belong to Neolaparus, owing to the 

 different formation of the moustache and the absence of 

 antennal style. It is distinguished from the other two 

 species placed in this genus by the more open fourth poste- 

 rior cell, the last part of its upper vein not turning sharply 

 downwards, and the first vein from the discal cell does not 

 bulge into the first posterior cell. It varies in size greatly, 

 judging from the specimens in the British Museum Coll., 

 which measure from 22-25 mm. (males), 15-22 (females). 



The moustache is composed of stout bristles. The antennce 

 are reddish yellow ; the first two joints with yellowish hairs 

 and some bristles ; the third bare, cylindrical, in one male 

 nearly three times as long, in two females only twice as long 

 as the first two joints together. The bristles at sides of 

 thorax'are rather short and yellow, the scutellum apparently 

 devoid of them. 



Neosaropogon salinator, Walker. 



Type ( ? ) and another female from Port Essington, 

 N. Australia, and a male and female from Port Darwin, 

 N. Australia [Buckland). 



Distinguished from Neosaropogon claripennis, sp. n., by 

 the shorter, more club-shapect third antennal joint, by the 

 wholly yellow legs (only the coxse are darker), and the more 

 distinctly banded abdomen. 



Length 23-27 mm. 



Yellowish, with black bands on abdomen. Face pale 

 yellow, the bristles yellowish white. Antenn(B reddish 

 yellow; the first two joints with yellow hairs and a few black 

 bristles ; the third bare, rather club-shaped, about one and 

 a half times as long as the first two joints together. Thorax 

 greyish brown, with traces of three black stripes ; sides with
