60 Mil. R. E. TURNEK ON 



clothed with grey pubescence; scutellum and median segment 

 very closely punctured. Abdomen elongate, shallovvly punctured ; 

 seventh dorsal segment truncate at the apex. Hypopygium 

 gradually narrowed to the apex, where it is narrowly truncate, 

 with a strong apical spine. Second abscissa of the radius longer 

 than the third ; first recurrent nervure received at two-thirds 

 from the base of the second cubital cell, second at one-fifth from 

 the base of the third cubital cell. A tuft of pale hairs on each 

 side at the base of the hypopygium. 



2 ■ Clypeus without a carina. Head shining, sparsely punc- 

 tured, broader anteriorly than long, narrowed posteriorly, the 

 hind margin not as broad as the head is long ; a rather deep and 

 large depression on each side of the head between the eyes and 

 the base of the antennas ; the head somewhat compressed at the 

 sides. Thorax much narrower than the head ; pronotum closely 

 punctured, half as broad again anteriorly as long, narrowed 

 posteriorly, with a longitudinal sulcus ; scutellum sparsely punc- 

 tured, narrowed towards the apex. Median segment very finely 

 and closely punctured, the dorsal surface a little longer than the 

 scutellum. First dorsal segment with a broad transverse groove 

 before the apex, second with four strong transverse carinse ; the 

 other segments shining, very sparsely punctured. Pygidium con- 

 stricted at the base, the surface of the posterior truncation ovate. 

 Tarsi slender. 



Hab. Cunderdin, W. Australia {Mrs. Lundy) ; July and 

 August. 



The male is rather near volatilis Sm., but the sculpture is 

 coarser, the details of neuration rather different, and the 

 scutellum has a yellow spot. The females of the two species are 

 very distinct.
