Gudr., and, as I have not seen Guerin's type, perhaps it is 

 better to use Smith's name pending further information.

I have not seen this species from Tasmania, but I have 

 received Victorian specimens answering to Erichson's descrij)- 

 tion. I have no doubt that his record of the species as 

 Tasmanian is quite correcr. 



Family Scoliidae. 

 Subfamily Anthoboscin^, Turn. 



Anthobosca Jlavicornis, Sauss.

One female from Tasmania in the British Museum collec- 

 tion has the tibise fulvous, not black as in the typical Aus- 

 tralian form. It is also more sparsely punctured. Easily 

 distinguished by the orange-yellow antennre. 



Anthobosca confusa, sp. n. 



? . Black, with sparse white pubescence, the spines of the 

 tarsi testaceous brown. Wings hyaline, nervures black. 



Clypeus shining, sparsely punctured, raised in the middle 

 into a smooth longitudinal carina, which is broadened 

 towards the apex. Head shining, sparsely punctured, 

 almost as sparsely and finely on the front as on the vertex, 

 no pubescence on the front. Thorax shining, very sparsely 

 punctured, median segment shining, very minutely punc- 

 tured. Abdomen shining, very shallowly and finely punc- 

 tured, with sparse larger punctures. Sixth dorsal segment 

 opaque, rather strongly punctured at the base, very minutely 

 in the middle, the apical margin smooth and testaceous. 

 The apical portion of the hind femora beneath is strongly 

 rounded and broad, but there is no well-defined apical lobe. 

 Radial cell broadly rounded at the apex, almost truncate ; 

 second abscissa of the radius scarcely longer than the tirst, 

 the third longer than the first and second combined. First 

 recurrent nervure received before the middle of the second 

 cubital cell, second just before the middle of the third cubital 

 cell. Tarsal ungues with a blunt basal lobe. 



Length 7-12 mm.
