100 NEW AUSTRALIAN ASILID^, 



Rhabdotoitamus mistipes, Macq. 

 Syn. Neoitamus mistipes, Macq. 



This species, which is unknown to me, was described 

 by Macquart, from Mount Gambier, South Australia. 



It is described as having ih© thorax blackish-brown, 

 covered with yellowish tomentum, with two median and. 

 two lateral black stripes ; thoracic bristles entirely black ; 

 scutellum with two weak yellow marginal bristles ; abdo- 

 men blaickish-brown, with j'ellowish tomentum, and yellow 

 latera.1 bristles ; femora black above, yellow below ; tibise 

 yellow with apical third black ; bristles of tibi?e and 

 tarsi vellow ; wings hyaline. 



This species should be readily distinguished from the 

 other speciesi, having the thoracic bristles entirely black, 

 by the vellow scut.ellar bristles, in conjunction with the 

 yellow bristles of the legs. 



R.IIABDOTOITAMUS BRUNNEUS, )\ /life. 



Syn. Neoitamua hrunnetis. White. 



This is probably the commonest and most widely 

 distributed species of the genus. It occurs in New South 

 Wales, Victoria, and Tasmania. It may be recognised 

 without difficulty by its uniform brown colouration, and 

 by the first antennal joint being red, instead of black, as 

 m the other known species. It occurs settled on the 

 ground on roads and on warm hillsides.

 blackish, but always with a red-brown tinge in jalaces, 

 the segmentations white, the white colouration being con- 

 fined to th© hindmargins of segments ; femora with the 

 upper surface black, the lower surface orange-brown, the 

 line of demarcation between the black and orange-brown

 brown.
