%vith remarks on some aberrant genera of the Scoliidie. 87 



In my recent revision of the Australian species of 

 Anthobosca (Proc, Linn. Soc. N.S.W., 1907) I gave Cosila 

 (Colobosila) fasciculata, Sich., as a synonym of A. anthraciiia, 

 Sm. This is ahnost certainly a mistake, as the radial cell 

 of anthracina, although obtuse at the apex, cannot be said 

 to be truncate. 



Cockerell (Bull. Mus. Comp. Zool. Harvard, 190G) has 

 described a new genus Austrotiphia for A. hirbyi. I have 

 not seen his paper, but the type of his species is in the 

 British Museum, and is certainly identical with Anthobosca 

 anthracina, Sm. This species does not seem to differ 

 appreciably in structure from the typical species of Di- 

 morphoptera, Sm., except in the radial cell, which is obtuse 

 at the apex. 



The genus Oclontothymms, Cam. (Rec. Albany Mus., i, 

 3, p. 161, 1904), containing two species from Grahamstown, 

 Cape Colony, is very closely allied to Anthobosca as far as I 

 can judge from the description, and should be placed in 

 the Scoliidse rather than in the Thynnidoe. His assump- 

 tion that the females are apterous will probably prove to 

 be erroneous. 



In the same publication (i, 5, p. 306, 1905) he refers 

 again to his genus, and suggests that Anthobosca antennata, 

 Sm., may belong to it. This is evidently a slip of the pen 

 for A. errans, Sm., but in that species the apex of the 

 clypeus is not bidentate, nor are the posterior tarsal ungues 

 simple. These distinctions, unless accompanied by ditfer- 

 ences in the female, are hardly in ray opinion of generic 

 value, and it is hardly advisable in this family to found 

 genera on one sex alone if it can possibly be avoided. The 

 maxillary palpi in Anthobosca are six-jointed, not as 

 Cameron, following Ashmead, states, five-jointed. 



The genus ^luroides described as a Thynnid by Tull- 

 gren (Arkiv. Zool., i, 1904) for A. sjostedti is erroneously 

 placed, and is synonymous with Apenesia, Westw., belonging 

 to the Proctotrupidae. It appears, therefore, that unless 

 we place Methoca in the Thynnidse, the family does not 

 occur in Africa. Methoca in my opinion has had an origin 

 independent of the Thynnidse.
