posterior'ocelli nearly as far from each other as from the 

 eyes, more than twice as far from the posterior margin of 

 the head as from each other ; eyes separated at the hase 

 of the clypeus by a distance about equal to half tbc length of 

 the scape. Thorax narrower than the head ; the proiiotuni 

 depressed, strongly rounded at the angles ; mesoiiotum 

 shining, microscopically punctured, without a sulcus. 

 INIedian segment smooth, with a shallow and rather indis- 

 tinct median sulcus, a narrow transverse foveolate groove at 

 the base. First abdominal segment a little slnn'ter than the 

 second, the apical halt' somewhat swollen, but not forming a 

 conspicuous node. Hind tibine swollen, with three or lour 

 short spines on the outer margin near the apex. Recurrent 

 iiervure received a little before two-thirds from the base of 

 the cubital ceil. 



Hab. Caloundra, near Brisbane; September. On tree- 

 trunks. (From Queensland ^Museum.) 



There is no distinct dcj)ression between the inner margin 

 of the eyes and the posterior ocelli. The species is easily 

 distinguished by the great lengtli of the head behind the 

 eyes.

 specimen at Yallingup was taken on a live Jarrah tree. 



The male has the petiole longer and less clavate than the 

 female. The spines on the hind tibise are almost obsolete.
