Neosaropogon froggattii, sp. n. 



The genus Neosaropogon was created by Ricardo for species 

 distinguishable from Saropogon by their large size, by the 

 absence of any visible style to the third joint of the antennae, 

 by the fourth posterior cell of the wing being not quite closed 

 or widely open, and by the moustache being composed of 

 numerous bristles about the same size arranged fan-like above 

 the oral opening. 



Three species were placed in this genus — viz., N.princeps^ 

 Macquart, JS. salinator, Walker, and iV. clavipennis, Ricardo. 

 The first and the last-named are only recorded from Eastern 

 Australia. N. salinator is recorded from the extreme north 

 at Port Darwin in the Northern Territory.

 is a female from the extreme south coast of Western Australia 

 — Bremer Bay. It is a large s))ecies (30-35 mm. in length),

 posterior segments, which are black. The legs are banded 

 black and yellow.
