I think this is a Calopompilus, though it is not quite certain, 

 the female being still unknown.

5 . Clypeus about three times as broad as long, the anterior 

 margin not quite transverse, very feebly and widely emarginate, 

 the labrum slightly exposed. Eyes very slightly convergent 

 towards the clypeus, separated on the vertex by a distance about 

 equal to the length of the first and two-thirds of the second joint 

 of the flagellum ; the posterior ocelli a little further from the eyes 

 than from each other. Front very feebly raised at the base of 

 the antenna?, marked with a short and shallow sulcus ; third joint 

 of the flagellum a little shorter than the second. Pronotum 

 strongly rounded anteriorly, the posterior margin rather feebly 

 arched, shorter than the mesonotum. Median segment fully 

 twice as broad as long, with a median sulcus, abruptly truncate 

 posteriorly. Abdomen subsessile ; the second ventral segment 

 with a transverse groove. Posterior tibiae spinose, with a ridge, 

 not serrate ; anterior tarsi without a comb, tarsal ungues with one 

 cooth. Second abscissa of the radius very little longer than the 

 third ; first recurrent nervure received at two-thirds from the base 

 of the second cubital cell, second at the middle of the third 

 cubital cell; submerlian cell longer than the median; cubitus 

 of hind wing interstitial with the transverse median nervure. 

 Opaque, pruinose. 



Black ; flagellum orange-yellow ; mandibles, labrum, anterior 

 tarsi and apical joints of all the tarsi fusco-ferruginous ; spurs of 

 the tibiae whitish ; a band of white pile on the apical margin of 

 the five basal abdominal segments. Wings fuscous, a subhyaline 

 band beyond the third transverse cubital nervure. 



Length 14 mm. 



Hah. Mackay, Q. {Turner). 



Specimens from Cumberland, N.S.W., have the second joint of 

 the flagellum nearly half as long again as the third, the apical 

 joint black, the second abscissa of the radius half as long again 

 as the third. 



Calopompilus nugenti, sp. n. 



$ . Clypeus very short and broad, transverse at the apex, the 

 labrum exposed. Head broader than long, the front not raised 

 at the base of the antennae, rather flat, smooth and shining. 

 Eyes almost touching the base of the mandibles, their inner 

 margins almost parallel, separated on the vertex by a distance
