PSEUDOTABANUS, gCU. 110V. 



Formed for two species from Queensland. 



Ocelli and spurs on hind tibia present. Antennae with 

 eight divisious on the third joint, which is broad and 

 Tabamts-like at the base, with the three divisions after the 

 first basal one indistinct ; the last four divisions small and 

 distinct, the first joint very short, hardly more than half 

 the length of the first four divisions of the third joint ; the 

 second smaller, cup-shaped. Palpi two-thirds the length of 

 the proboscis, Tabantis-Vike. Wings with all posterior cells 

 open ; no appendix. 



The species resemble in general appearance species of the 

 genus Tubulin*. Proboscis short.
