"238 REVISION OF THE THYNNID.E OF AUSTRALIA, II., 



194. T. nigripes Guerin. 



Thynnoides nigripes Guer., Mag. de Zool. xii. p. 10, 1842. 



The original description is poor, and I have not seen the type. 

 There is a damaged specimen in the British Museum which may 

 belong to this species, but the hypopygium does not answer to 

 the description, being without an apical spine, which may pos- 

 sibly have been broken. In any case I do not think the species 

 will come at all near typical Thynnoides. 



Hab. — Swan River(Guerin). 



195. T. simplex Sm. 



Tkynnus simplex Sm., Descr. n.sp. Hym. p. 167, n.26, 1879((J). 



(J. Clypeus very prominent at base. Scutellum long, narrowly 

 .truncate at apex; abdomen shining, sparsely and shallowly punc- 

 tured, first ventral segment with a carina from base, produced at 

 apex into a curved tubercle overhanging the deep groove between 

 tirst and second segments. Sixth ventral segment with a spine 

 on each side at apical angles. Hypopygium with a blunt pro- 

 minence near basal angles, thence broadly produced and gradually 

 narrowed, rounded at apex, with a short apical spine; transversely 

 striated above. 



Hab. — Champion Bay, W.A.(Du Boulay). 



196. T. crudelis, n.sp. 



£. Clypeus rugulose, produced and rather narrowly truncate 

 -at apex, prominent at base. Head finely rugose, interantennal 

 prominence broadly truncate at apex, a delicate longitudinal 

 carina from a little below anterior ocellus almost reaching base 

 of clypeus. Thorax finely and very closely punctured; pronotum 

 a little narrower than head, anterior margin straight and 

 slightly raised. Median segment rounded, finely rugulose, with 

 a strong median sulcus from base to apex. Abdomen elongate, 

 very finely and shallowly punctured; segments 2-5 with an 

 impressed transverse line near base and a strongly raised trans- 

 verse mark on each side just before apical margin above and
