each side of the posterior tiuncatiou near the middle. First 

 recurrent nervure interstitial with the first transverse cubital 

 nervure, third cubital cell longer on the radius than on the 

 cubitus.

2 . Nigra ; mandibulis, scapo, flagello dimidio basali, tegulis, seg- 

 mento abdominali primo nonnunquarn infuscato, segmento sexto, 

 femoribus supra, tibiis tarsisque ferrugineis ; segmentis dorsalibus 

 2-5 margine apicali bruuiieis, aureo-pilosis ; alls h jalinis, veuis

 Long. 9 mm, 



$ . Clypeus covered with shining golden pubescence, very 

 feebly convex; second joint of the fiagidkun equal to tlie 

 third, more than twice as long as the first; posterior ocelli 

 as far from each other as from the eyes. Head and thorax 

 coarsely and closely punctured ; scutellum longitudinally 

 rugose-striate ; pronotum covered on the upper margin witli 

 golden pubescence. Median segment very coarsely reticulate, 

 narrowed and rounded posteriorly ; the surface of the steep 

 posterior slope covered with golden pubescence, with a 

 median sulcus and with a small acute spine on each side near 

 the middle. Abdomen more finely and shallowly punctured ; 

 second ventral segment rounded at the base, not angular 

 or tuberculate; first segment narrow at the base. Pulvilli 

 long, forked at the apex when extended. Third cubital cell 

 distinctly longer on the radius than on the cubitus, first 

 recurrent nervure received by the second cubital cell at a 

 distance from the base equal to the length of the petiole of 

 the second cubital cell. 



Hah. Marybcrough, S. Queensland; Brisbane {Hacker). 



In the Bii-bane specimen there is a distinct longitudinal 

 carina on the median segment, which is present, though more 

 indistinct, in the Maryborough specimen. 



It is possible that this may be the female o^ pilosellus, but 

 in that species the first recurrent nervure is interstitial with 

 the first transverse cubital nervure, and the cubitus of the 

 hind wing originates nearer to the transverse median nervure. 

 The first abdominal segment is much more strongly nan-owed 

 to the base in this species than \n pilosellus.
