250 REVISION OP THE THYNNIDiE OP AUSTRALIA, II., 



Hab. — Adelaide (Westwood); Melbourne (French); Mittagong, 

 N.S.W.(Froggatt). 



South Australian specimens seem to be usually much larger 

 than others, but they do not differ otherwise. 



212. T. servillei Lep. 



Elaphroptera servillei Lep. St. Farg., Hist. Nat. Ins. Hym. iii. 

 p.571, n.2, P.36, fig.l, 1845(£). 



"Antennes noires. Tete noir, ses poils noirs, mandibules a 

 base rousse, a bout brun. Chaperon roux. Corselet et abdomen 

 d'un gris noir, un peu velus. Pattes d'un testace roussatre. 

 Ailes un peu enfumees, quoique transparentes, nervures brunes; 

 cote et point marginal roux. Male. Long. 5 lignes. 



Nouvelle Hollande, Musee de M. Serville." 



I am quite unable to identify this species from the description, 

 nor does the figure give much assistance. 



213. T. humilis Erichs. 



Thynnus humilis Erichs., Arch. f. Naturg. viii. 1, p.264, n.238, 

 1842(9). 



I have not been able to identify this species, nor does the 

 description enable me to assign it to any of the subgenera. 



The following species allied to the typical dentatus-group of 

 Thynnus have been described from the Austro-Malayan region. 



Thynnus atratus Sm. 



Thynnus atratus Sm., Journ. Proc. Linn. Soc.vi. p. 51,1861 ($)',
