shoulder tubercles brown, and a yellow spot on 

 each side, a little above and in front of the base of wings, 

 the whole bearing black lateral pubescence, which is most 

 conspicuous anteriorly, and black bristles; scutellum 

 (black, and bearing numerous black marginal bristles. 

 Abdomen black, with yellow side-spots, and white lateral 

 pubescence, the first segment bearing also white lateral 

 bristles. Legs with femora having the basal two-thirds 

 bright yellow, apical third black, devoid of bristles, but 

 with abundant long soft pubescence, that on the yellow 

 portion being white, on the black portion black; tibiae 

 with basal two-thirds bright yellow, apical third black, 

 with short white and black pubescence disposed as on the 

 femora, the whole bearing also stiff black bristles ; tarsi 

 black, with black bristles. Wings greyish-brown ; lae 

 first posterior cell open, but narrowed on the margin to 

 about half its breadth ; fourth posterior cell very narrowly 

 open, or closed bluntly en the extreme wing margin ; anal 

 cell very narrowly open, llalteres brown. 



Female resembles the male very closely, but tlie 

 moustache is entirely white, and the abdominal lateral 

 pubescence somewhat shorter. 



This species lesembles Thentfrid ninnracua, Walk., 

 very closely, but diffei^s in the femora having at least the 

 apical third black instead of only the extreme apex, also 

 in the coloured portion of the femora and tibia? being a 

 bright yellow of the same tint, instead of. as in T. omar<i- 

 nis, the femora being orange-red and the tibiae pale-yellow. 



T. pulrhripes also differs from T. amnrnnix in the 

 whiter moustache, and the more narrowed fourth posterior 

 cell. 



Of this species, a male from Lcura, N.S.W., was 

 kindly given me by Dr. Ferguson, and a female from Vic- 

 toiia by Mr. C. French, Jr.

The species contained in this genus bear a very close 

 resemblance to those of Tlitrtitria, but are distinguished by 

 the face being flat, without a tubercle, and by the mous- 

 tache consisting of a single row of hairs confined to the 

 oral opening. The genus was proposed bv Miss Ricardo' 

 for a North Australian species ; a New South W^ales sjiccies 

 is now added.
