129. T. (Lophocheilus) australis Boisd. 



Thynnus australis Boisd., Voy. Astrolabe, Zool.ii. 6, p. 655, P. 12, 

 fig.2, 1833(<J). 



I cannot identify this species from the very poor description, 

 and the figure is utterly useless. I cannot, however, see any 

 cause for supposing it to be identical with T. annulatus Kirby, 

 of which it has been regarded as a synonym by many authors, 

 who have followed a vague suggestion of Guerin, who is careful 

 to state that he had not seen either species. 



This may prove to be a form of T. rufiventris Guer. The 

 length of the figure is 23 mm. 



Hab. — Port Western(Boisd.). 



130. T. (Lophocheilus) immodestus, n.sp. 



(J. Clypeus strongly produced and rather broadly truncate at 

 apex, convex and strongly punctured; a short tubercle at base of 

 each antenna. Head and thorax very closely punctured, with 

 thin pubescence, longest on sides of head; scutellum long, broadly 

 truncate at apex. Median segment finely rugulose. Abdomen 

 elongate, narrowed at base, smooth and shining, with a few 

 scattered punctures. Hypopygium bluntly produced at sides 

 near base, thence triangular to base of short apical spine. Black; 

 clypeus and mandibles yellow; pronotum, tegulse, a quadrate 

 spot on mesonotum, scutellum, abdomen beneath and legs dull 

 ferruginous; a spot on each side of all the abdominal segments 

 and the whole of the seventh segment ferruginous-orange. Wings 

 flavo-hyaline. Length 20 mm.
