Rhopahim eucalypti, sp. u. 



$ . Nigra ; scapo subtus, tarsis anticis interinediisque, tibiis anticis 

 interinodiisque supra, tibiisque posticis subtus albido-tiavis ; alis 

 bvalinis, iridesceutibus, venis nigris. 



Long, (j-5 mm. 



Clypeus without a carina, sliallowly emarginate at the 

 apex, the angles of the emarginatiou forming very short 

 teeth. Eyes separated at the base of the antennte by a 

 distance equal to about three-quarters of tiie length of the 

 scape ; no broad groove on the inner margin of the eye level 

 with the anterior ocellus, but a narrow shallow sulcus runs 

 frooi the eye to the posterior ocelli, wliich are as far from 

 each other as from the eye. Dorsal surface of the median 

 segment smooth and shining, with a rather obscure median 

 sulcus and a few very short striee at the base. Petiole longer 

 than the second segment, the apical third moderately 

 swollen ; second segment slender, fully twice as long as the 

 apical hreadtii ; pygidial area triangular, not very sharply 

 defined. Hind tibiae swollen towards the apex, without 

 spines. Radial cell broadly truncate at the apex ; trans- 

 verse cubital nervure joining the radius at two-tifths from 

 the base of the radial cell ; recurrent nervure received at 

 about three-fifths from the base of the cubital cell. 



Hab. EaglehawU Neck ; March. 



Taken on a dead Eucalyptus log. 



This is a more slender species than variitarse, and is 

 without the groove on the inner margin of the eye and the 

 spines on the Innd tibiffi. The eyes arc much farther apart 

 on the front, in this character more nearly approaching 

 frenchii, from which it is easily distinguished by the long 

 petiole. 



Rhopalum alicicE, sp. n. 



$ . Nigra, subnitida ; scapo, tuberculis humeralibus, femoribns 

 anticis intermediisque apice, tibiis basi, tarsisque articulo apicali 

 exoepto albido-flavis ; alis hyalinis, venis nigris. 



c? . Feminae similis. 



Long., 2 1^." cJ 9 ni™. 



? . Eyes separated at the base of the clypeus by a distance 

 equal to about two-thirds of the length ot the scape. Poste- 

 rior ocelli nearly half as far again from the eyes as from each 

 other, a little farther from the eyes than from the posterior 

 margin of the head ; a broad oblique depression reaching 

 from the inner margin of the eye almost to tlie })osterior
