STUDIES IN THE FOSSORIAL WASPS. 733 



Black, with sparse grey pubescence ; flagellum beneath fuscous ; 

 tarsal ungues ferruginous ; calcaria white. Wings light fuscous, 

 shaded with bronze ; nervures black. 



Length 13 mm. 



Hah. Adelaide, S. Australia. 



1 think I have identified this species correctly. Gribodo 

 mentions a tubercle at the base of the first venti-al segment, 

 which does not seem to be any more developed in the specimen 

 described above than in other species.

2 . Radial cell very bluntly rounded at the apex ; second 

 abscissa of the radius shorter than the first, the thii'd abscissa 

 half as long again as the first and second combined. First 

 recurrent nervure received just beyond, the middle of the second 

 cubital cell, which is more shai-ply produced towards the base 

 than in tmicolor Sm. or Icevifrons Sm. ; second recurrent nervure 

 received at two-fifths from the base of the third cubital cell, 

 which is longer on the radius than on the cubitus. Basal joint 

 of hind tarsi finely pectinate beneath ; basal joint of fore tarsi 

 with six spines above and eight finer beneath ; basal lobe of tarsal 

 ungues bluntly rounded. Finely and rather sparsely punctured, 

 pronotum more coarsely punctured, median segment very finely 

 and closely punctured with a smooth line in the middle. 



Black with whitish pubescence; spines of the tibife and tarsi 

 white, those of the anterior pair slightly reddish. Wings 

 hyaline, shaded with fuscous towards the apex, nervures pale 

 testaceous. 



Length 14 mm. 



Hah. S.E. Australia ; Adelaide to Sydney. 



The description is taken from the type of anthracina. The 

 type of sahulosa has the first and second abscissae of the radius 

 about equal in length, combined equal to the third ; the third 

 cubital cell no longer on the radius than on the cubitus; the 

 nervures are fuscous. But excepting in these points I cannot 

 detect any difi"erence, and do not consider that small difierences 

 of neuration can be held to be of specific importance, considering 

 how much variation occurs in other groups of Scoliidse in such - 

 detail. The type of Austrotiphia hirhyi is similar to sahulosa.
