SOME AUSTRALIAN WASPS.— HACKER AND COCEEBELL. 289 



ZOYPHIUM AFFINE, new species. 

 Female. Length 6 mm. Clypeus transverse, rather narrow, the apical margin 

 wtih two minute teeth on each side ; the posterior ocelli a httle nearer to the eyes 

 Ihan the diameter of one ; face about two-thirds as wide at the vertex as at the clypeus, 

 clothed with short silver pubescence, which also covers the front up to level 

 of ocelli ; mesonotum and scutellum subopaque, finely punctured ; a deep trans- 

 verse groove at the base of the scutellum ; median segment with a central 

 longitudinal carina lying in a shallow sulcus ; area diagonally striated, the striae 

 most distinct on basal line and on the sides of sulcus ; abdomen shining, micro- 

 scopically punctured ; pygidial area triangular, clothed with short black hair ; 

 intermediate and posterior tibiae armed with a few short spines on the outer edge ; 

 second submarginal cell pointed on the radius, receiving the second recurrent 

 nervure two-fifths from the apex ; first recurrent nervure received at about the 

 same distance from the apex of the first submarginal cell. 



Black, base of mandibles, clj^peus, scape, first joint of flagellum, and the 

 anterior coxae flavous ; legs shining chrome-j^ellow ; flagellum ferruginous ; wings 

 hyaline, iridescent, faintly dusky, nervures brown. 



Male. Length 4 mm. Clypeus yellow, without teeth ; face clothed \\ith silver 

 pubescence as in the female ; hypopygium ferruginous, obtusely rounded at the apex, 

 with an obtuse tubercle on each side. 



Hab. — Brisbane {Hacl-er), February. 



This species is very close structurally to Z. crassicorne Ckll., from which it 

 may be separated by the silver (instead of golden) pubescence on face (golden in 

 crassicorne), and the bright yellow clypeus in both sexes (pale ferruginous and dusky 

 in crassicorne). It is also related to Z. cloddi Turner. 



ZOYPHIUM FUSCIPENNE, new species. 



Female. Length about 7 mm. Closely related to Z. iridlpenne Turner for 

 which it was at first mistaken, but larger, and evidently distinct by the dusky, pale 

 brown wings, those of iridipenne being clear. The stigma is dark-brown, while the 

 nervures are pale-brown, not black. The second recurrent nervure is received at 

 more than three-quarters from base of second submarginal cell. In other respects 

 the insect agrees with Turner's description of iridipenne, but it should be stated that 

 the abdomen is dusky red at apex, and the flagellum is brown beneath. The silvery 

 hair on face and lower part of front is thin and not brilliant, its outline on the front 

 is in the form of a very broad V. 



Hab.— Wedge Island, Tasmania, 4-1-1914 {G. H. Hardy). 



Subfamily ARPACTIN^. 

 ARPACTUS CRUCIGERA, new species. 

 Female. Length 9 mm. Head, thorax, and abdomen finely and closely 

 punctured ; eyes not convergent towards the clypeus ; posterior ocelH a little 

 further from each other than from the eyes ; front and sides of face clothed with
