STUDIES IN THE POSSORIAL WASPS. 731 



Length .11-14 mm . 



Hah. Victoria. 



There is also a specimen in the National Collection from 

 Tasmania and another from Cairns, Queensland. In the former 

 the i-adial cell is rounded at the apex and the tibite and tarsi are 

 reddish ; in the latter the radial cell is almost truncate at the 

 apex, though narrowly, and the second abscissa of the radius is 

 as long as the first. I do not think that small diflferences of 

 neuration in this genus will prove to be of specific value.

$ . Radial cell rather broadly rounded at the apex ; the four 

 abscissae of the radius of about equal length ; the third cubital 

 cell much longer on the cubitus than on the radius. Recurrent 

 nervui-es received close to the middle of the second and third 

 cubital cells ; the second cubital cell strongly produced toward 

 the base on the cubitus. Basal joint of hind tarsi with a scopa 

 beneath in which ai-e five or six longer spines ; basal joint of fore 

 tai-si with six long and rather slender spines above and a closely 

 set row of veiy small spines beneath ; basal lobe of tarsal ungues 

 less bluntly rounded than in fiavicoruis. The lobe beneath the 

 apical half of the hind femora is very broadly rounded. Closely 

 and finely punctured, more finely and closely on the abdomen 

 and median segment than on the head and thorax, some larger 

 punctures on the disc of the mesonotum. 



Black, with sparse whitish pubescence ; mandibles at the base 

 and legs, except the coxse, ferruginous. 



Length 11 mm.

2 . Radial cell broadly rounded at the apex ; second abscissa 

 of the radius twice as long as the first and distinctly longer than 

 the third ; first recurrent nervure received at one-quarter from 

 the base of the second cubital cell, second at one-fifth from the 

 base of the third cubital cell. Apical lobe beneath the hind 

 femora broadly rounded and sti-ongly developed. Pronotum, 

 median segment, and abdomen very finely and closely punctured, 

 front coarsely and closely, mesonotum and scutellum less coarsely 

 and rather sparsely punctured. 



Black ; the pubescence pale fulvous on the head and pronotum, 

 grey on the sides of the abdomen, fusco-ferruginous on the apical 

 dorsal segment ; apex of the scape and flagellum beneath fusco- 

 ferruginous, a dull ferrviginous spot on each side close to the 

 summit of the eyes ; mandibles at the base, tegulse, tibife, tarsi,
