550 Mr. R. E. Turner on Fossorial Hymenoptera. 



cJ . Opaque black ; mandibles at the base, clypeus, poste- 

 rior margin of the pronotum, tegulse, a transverse spot on the 

 postscutelluni, and the tibise in front pale yellow ; calcaria 

 whitish. Wings hyaline, iridescent, nervures black. 



Clypeus broad, almost transverse at the apex. Antennas 

 stout, a little shorter than the thorax and median segment 

 combined. First abdominal segment distinctly, though only 

 slightly, longer than the second, longer than its apical 

 breadth, gradually widened from the base. Third abscissa o£ 

 the radius as long as the first and second combined, the 

 second longer than the first. The second recurrent nervure 

 is received at two-fifths from the base of the third cubital 

 cell, the first at the middle of the second cubital cell. 



Length 6 mm. 



Ilah. Eaglehawk Neck ; February. Mt. Wellington, 

 1300 ft.; January. Ulverstone [Lea). 



Somewhat intermediate in the female between unicolor, 

 Sm., and Icevifrons, Sm. From unicolor it differs in the 

 absence of the strong puncturation of the front and the long 

 hairs rising therefrom, also in the position of the second 

 recurrent nervure ; from Icevifrons in the puncturation of the 

 head, in the broadening of the carina of the clypeus, in the 

 absence of ferruginous colour on the mandibles and antenna3 ; 

 and from both in the lesser development of the lobe at the 

 apex of the hind femora. 



The male differs from frencM, Turn., in the longer first 

 abdominal segment and the yellow clypeus, and from lagardei. 

 Turn., in the same manner as to the first segment and also 

 in the absence of yellow markings on the seventh dorsal 

 segment. 



My record of um'cvlor, Sm., from Tasmania (Proc. Zool. 

 Soc. London, p. 734, 1912), applied to this species, but 

 further material has convinced me that it is distinct. 



The female is the type, 



Scolia [Dielis) tasmamensis, Sauss.

I have not seen specimens of this common Australian 

 species from Tasmania, but have no reason to doubt 

 fcaussure's record. It has usually been known under the 

 Yinine formosa, Guer., which is quite a different species, which 

 does not range south of Cairns in North Queensland.
