The species of this genus are at once distinguished by the 

 hatchet-shape of proboscis, by the curved anal vein of wing 

 and open anal cell, and by the subulated antennae. The dis- 

 tribution of the species is interesting, the known species all 

 being found in Australia and Chile (S. America). The species 

 now number eight, three of them being described for the first 

 time ; only two out of the eight come from Chile.

 Wings not marked with dark spots or

anterior part of sides of thorax blackish, 



hairs on base of cheeks yellow maculipennis, Macquart.
