170 REVISION OF THE THYNNIDiE OF AUSTRALIA, II., 



9. Head shining, very sparsely punctured, slightly convex, 

 much broader than long, narrowed and rounded posteriorly; eyes 

 oval and almost touching base of mandibles; a very short longi- 

 tudinal sulcus between antennae. Thorax and median segment 

 very finely and closely punctured; pronotum rectangular, about 

 twice as broad as long; median segment oblique from mesonotum. 

 Abdomen much broader than thorax, the segments smooth at 

 base, sparsely punctured at apex; first segment with the apical 

 margin raised and a broad groove before it; second segment with 

 about seven transverse carinas, including the raised apical margin 

 which is rather broadly separated from the other carinas, the 

 carinas in the middle broken and irregular. Fifth ventral seg- 

 ment coarsely rugose. Pygidium lanceolate, sides nearly parallel. 

 Black; legs and pygidium ferruginous; antennas and mandibles 

 fuscous. Length 10 mm. 



Hah. — Tasmania, Huon River (Lea). Type of Q in Brit. Mus. 



Some specimens of the male have indications of a carina on 

 the clypeus. 



Guerin's description is very poor, but I think I am right in 

 identifying his L. villosus with T. niger Sm., from the type of 

 which my description is taken. It is a common Tasmauian 

 species, but does not seem to occur on the mainland. 



107. T. (Lophocheilus) fervens Sm. 



Thynnus {Agriomyia) fervens Sm., Cat. Hym. B.M. vii. p.31, 

 n.79, 1859(<J). 



$. Clypeus short, rather narrowly produced and truncate at 

 apex, with a strong carina from base to apex and closely punc- 

 tured. Abdomen fusiform; hypopygium very short and broad, 

 slightly prominent at basal angles, thence rounded to apex, with 

 a minute apical spine. 



Hah. — Australia (Smith).
