the AsiliJte of Australasia. 151 



Bathypogon, Loew, 

 Progr. Realscliule, Meseritz, 1851, p. 13 (1851). 



This genus was formed by Loew for his species B. asiU- 

 formis from Australia, and Schiner added B. brachypterus, 

 Maoq., besides other species from Chili. 



The genus belongs to the group of Dasj/pogonincB with no 

 spine on fore tibiae and is distinguished by the rather short 

 wings with the fourth posterior cell closed and the first 

 widely open, the vein closing the fourth posterior cell is 

 nearly on a line with the one closing the discal cell; the 

 face has a distinct tubercle, with the moustache reaching the 

 antennae, which have a style-like bristle on the end of the 

 third joint. It appears to be distinguished from Stenopogon 

 by the broader face. 



The statement in Schiner's table that the wings in this 

 genus in proportion are long and narrow, is somewhat mis- 

 leading, so far as concerns its relationship to the other 

 Australian genera of Dasypogoninee, from which it is clearly 

 distinguished by the rather short narrow wings, often not 

 reaching far beyond half the length of the abdomen. 



The following described and one new species, all from 

 Australia, now belong to this genus. 



The differences between some of the species are very small 

 and probably with the advent of fresh material some will 

 hardly be maintained as distinct.
