The centrally transhnpressed basal segments \vill instantly 

 distinguish this very distinct genus from the whole of the other 



The name Bas#tts, apparently a word of no meaning, was first 

 employed by Fabricius in his ' Sy sterna Piezatorum ' of 1804; 

 but the concourse of species there assembled under this name is 

 truly diverse and includes CBYPTIIOE, PIMPLIX.E,' OPHIONIXA', 

 and even several kinds of BRACONID.E (cf. Curtis, Brit. Ent. 

 pi. Ixxiii). Several of his species, not one of which actually 

 belongs here, are still catalogued under this genus by Dalla 

 Torre, simply because they have never been subsequently re- 

 cognised. But Bassus totatorius, universally regarded as its 

 type, was not even included here till so placed by Panzer in 

 1806. Nor can we at all suppose that Gravenhorst used the 

 genus in the Fabriciau sense, for it was originally described as 

 having, inter alia, " corpus fere cyliudricum, glabrum ; antennis 

 longitudine corporis ; abdomine vix petiolato ; aculeo varissime 

 exserto," &c. The genus, as here defined, was in reality created 

 by Fallen in his ' Specimen novarn Hymenoptera disponendi 

 methodum exhibens " of 1813.
