powerful; femora and tibiae with numerous strong bristles. 

 Wings large and broad, either hyaline or tinted with brown 

 or yellow, but without any definite markings; first pos- 

 terior cell (in Australian species) wide open ; fourth 

 posterior cell open, but constricted on the wing margin ; 

 anal cell closed on the wing margin or very slightly open. 



The species belonging to this genus, like those of 

 Bathypogon, are strong, predaceous insects; their habits, 

 however, are somewhat different, as, instead of settling on 

 the ground, they frequent low vegetation. I have noticed 

 a, specimen of >S'. ehmcjatxn-: having as its prey a specimen 

 of the March Fly, Tahanm^ microdonta. 



Stenopognn is represented in Tasmania by the single 

 species *S'. elonaatus, which also occurs commonly on the 

 Australian mainland.
