mcillan depression which is lully half as broad as long, and 

 in wliich lies a stroi\g longitudinal carina, the dej)res.sion 

 disliiicfly margined, the posterior truncation of the segment 

 with a strong median carina. First abdominal segment 

 strongly rounded at the basal angles, not truncate. Tho 

 whole insect finely and closely pinictured, and clothed in 

 many |)laccs with short sericeous pubescence. Second cubital 

 cell j)ointed, receiving the second recurrent nervure at about 

 onc-tiiird from the apex, first recurrent nervure received at 

 a slightly greater distance from the aj)ex of the first cubital 

 cell. 



(J. Antennas twelve-jointed, the apical joiiit conical, 

 slightly hollowed on the outer side ; tibiie much less spinoso 

 than in the female.

The commonest species of the genus. Rohwer's descrip- 

 tion of Zojjphium rujipes answers to this species very well, 

 but he does not mention the bronze colour of the abdomen or 

 tlie appendiculate radial cell.

 Long. 7 mm. 



? . Clypeus very broadly rounded at the apex, without 

 lateral teeth. Head and thorax very closely and finely 

 punctured, a shallow longitudinal sulcus on the front ex- 

 tending from the anterior ocellus more than halfway to the 

 base of the clyptus ; posterior ocelli nearly three times as 

 far from each other as from the eyes. Pronotum almost 

 vertical ; the median segment with a broad longitudinal 

 groove, which broadens from the base to the apex. Radial 

 cell with a distinct appendix ; second cubital cell pointed on 

 the radius, receiving the second recurrent nervure at about 

 one-fifth from the apex, first recuirent nervure received at 

 the same distance from the apex of the first cubital cell, 



Ilalu Swan River, Western Australia. 



The apical joints of the antennas are missing in the type 

 which is unique. 



Superficially the resemblance to Zoi/jJiiuni errjthrosoma, 

 Turn., is very strong.
