90 Mr. E. E. Tuniei' on Fossorial Ili/menoptera. 



Rhopalum eucalypti, sp. n. 



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

 iuterinediisque supra, tibiisque posticis subtus albido-tiavis ; alis 

 byaliuis, iridescentibus, venis nigris. 



Long. Q'b mm. 



Clypeas witliout a Carina, sliallowly emarginate at tlie 

 apex, the angles of the emarginatioii forming very short 

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

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

 scape ; no broad groove on the inner mai'gin of the eye level 

 with the anterior ocellus, but a narrow shallow sulcus runs 

 from the eye to the posterior ocelli, which 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 strise at the base. Petiole longer 

 than the second segment, the apical third moderately 

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

 apical breadth ; pygidiai 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-fifths from 

 the base of: the radial cell ; recurrent nervure received at 

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



Hab. Eaglehawk Neck ; March. 



Taken on a dead Eucahj2)tus 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 hind tibiae. The eyes are much farther apart 

 on the front, in this character more nearly approaching 

 frenchii, from which it is easily distinguished by the long 

 petiole. 



Rhopalum alicia, sp. n. 



5 . Nigra, subnitida ; scapo, tuberculis humeralibus, femoribus 

 anticis intermediisque apice, tibiis basi, tarsisque articulo apicali 

 exoepto albido-fiavis ; alis hyalinis, venis nigris. 



(S . Pemina3 similis. 



Long., 5 12. J 9 mm. 



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

 equal to about two-thirds of the length ot' tiie 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 the posterior
