striatious, sides obliquely striated, the central longitudinal furrow of 

 the middle segment is wider by far on the upper surface, fore tarsi

 third transverso-cubital nervure received by the marginal cell at its 

 apex ; abdomen with strong, sparse punctures, those at the apex of 

 2, 5, and bases of 3, 5 closer ; punctures of ventral segments larger :

 Australian species of Cosila.
