Pachypi'osopis saturnina, sp. n. 



5" . — Length 4-4^ mm. 



Like P. humeralis, Ckll,, but differing thus : — Scutellum 

 with a hirge yellow cruciform mark, rather suggestive of" the 

 planet Saturn ; face, legs, and underside of abdomen orange, 

 though the patches at sides of mesothorax are clear yellow ; 

 lateral face-marks gradually tapering from clypcus to a very 

 fine line which runs to top of eyes ; scape slender (doubtless 

 a sex-character) ; mesothorax with two fine, short, yellow 

 antero-discal lines ; abdomen with only one light band, that 

 at apex of first segment. The mesothorax is microscopically 

 tessellated, with rather numerous minute punctures j in 

 P. humeralis it is quite the same. 



Another specimen is not well coloured, but I think the 

 scutellum would have been all yellow. 



Hub. Purnong, near Murray River, S. Australia [S. W. 

 Fulton; Nat. Mus. Vict. 225, 233). 



This is probably not the undescribed female of P. humeralis, 

 as it seems unlikely that that sex would have the large yellow 

 scutellar mark wanting in the male.
