BY ARTHL'U WHITE. 77 



Antennae slightly longer than the head, the first and 

 second joints short, and of about equal length, the third 

 twice the length of the first two together, and provided 

 with a short pointed style. Thorax almost bare of pubes- 

 cence, but with lateral and posterior bristles ; scutel- 

 lum without bristles. Abdomen rather broad, and not in 

 the least petiolate, altogether without bristles. Legs with 

 femora somewhat swollen, practically bare, but wilh a few 

 small, inconspicuous apical and pre-apical bristles ; tibiae 

 slender, with long, fine bristles; tarsi with remarkably long 

 bristles. Wings with three submarginal cells, the upper 

 branch of the cubital fork being connected with the radial 

 vein by a crosweinlet ; marginal cell broadly open ; the 

 three basal cells of almost equal length ; all posterior cells 

 wide open; anal cell closed. 



This genus is proposed for a remarkable species, of 

 which Dr. Ferguson took a number of specimens at Never- 

 tire, New Sovitli Wales. The species in shape and mark- 

 ings bears a close resemblance to the Therevidae, and has, 

 indeed, been identified as such by a well-known authority ; 

 it is, however, a tnie Asilid. In the character of the 

 thres submarginal cells the genus agrees with the Palae- 

 arctic and North American genus I'lii/imoxnnid, of the sub- 

 family J.d phrii'tt' \ from this genus, however, it may be at 

 once distinguished by the open marginal cell, and the wide- 

 ly open first and fourth posterior cells. 



Tt is worth noting that this curiaus genus comes from 

 one c^ the cntomclogically little known inland districts ; it 

 probably does not extend to the coastal region. Only a 

 single species is at present know^n, but it is not unlikely 

 that other .species will come to hand when the inland Aus- 

 tralian fauna is properly investigated.
