1908.] AUSTRALIAN FOSSORIAL WASPS. 477 



clypeus opaque, very minutely punctured, clothed with rather 

 coarse silvery pubescence, the apical margin transverse, ver)' 

 feebly emarginate in the middle and broadly smooth and shining. 

 The second joint of the flagellum is a little less than twice as long 

 as the first, a little longer than the third, and a little shorter than 

 the fourth. Head opaque, the front clothed with rather coarse 

 silvery pubescence ; the eyes separated on the vertex by a distance 

 rather less than the third joint of the flagellum. Pronotum 

 steejDly, but not nearly vertically sloped, higher in the middle 

 than at the sides ; the mesonotum broadly but shallowly de- 

 pressed anteriorly, with sparse pubescence of a dull silver colour 

 on the sides and in the depression. Median segment opaque, with 

 a short longitudinal carina from the base not reaching the middle, 

 very finely and closely punctured and very sparsely covered with 

 short grey pubescence, a few short transverse striae near the apical 

 angles, the face of the posterior truncation very shallowly and 

 irregularly transversely striated, with a deep and broad median 

 sulcus, the sides of the segment almost smooth, delicately obliquely 

 striated at the base ; the segment much longer than bioad. The 

 four basal abdominal segments with broad bands of rather dull 

 silvery pubescence on the apical margin ; the pygidial area rounded 

 at the apex, rather broad, and clothed Avith shining whitish 

 pubescence ; the second and third ventral segments convex, the 

 second subcarinate at the base. The distance between the two 

 recurrent nervures is less by about one-third than that between 

 the first recurrent nervure and the base of the second cubital cell ; 

 the third cubital cell is more than half as long again as the second 

 on the cubital nervure. 



Black ; the five or six apical joints of the flagellum, the apex of 

 the joints of the tarsi, and the whole of the apical joint beneath 

 fulvous ; tegulfe testaceous. Wings subhyaline, nervures fusco- 

 ferruginous. 



Length 13 mm.

2 . Clypeus opaque, clothed with silvery pubescence, the apical 

 margin broadly smooth and shining, transverse. Second joint of 

 the flagellum a little more than half as long again as the first, the 

 second and third subequal, shorter than the fourth. Head opaque, 

 the front clothed w"ith short silvery pubescence ; the eyes separated 

 on the vertex by a distance equal to three-quarters of the length 

 of the second joint of the flagellum. Mesonotum closely and 

 microscopically punctured, longitudinally and rather broadly 

 depressed in the middle anteriorly, with a short and fine longi- 

 tudinal sulcus in the depression, the disc with sparse and \evy 

 short cinereous pubescence, the sides with closer pubescence of a 

 silvery colour slightly tinged with pale golden. Median segment 

 opaque, very finely granulated, much longer than broad ; the 

 surface of the posterior truncation strongly transversely striated,.
