Icn>ECJMOMD.T:. 



The name Bassas, apparently a word of uo meaning, was first 

 employed by luibricius in his ' Systema Piezatorum ' of 1804; 

 but the concour.se of species there assembled under this name is 

 truly diverse and includes CETrTiK.E, Pimi'LIX.k, OphiokintK, 

 and even several kinds of Bkacokid.I' ((•/". Curtis, Brit. Eut. 

 pi. Ixxiii). Several of his species, not one of A\hich actually 

 belongs liere, are still catalogued under this genus by Dalla 

 Torre, simply because they have never been subsequently re- 

 cognised. But Bassiis Jd'tatorius, universally regarded as its 

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

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

 genus in the Fabrician 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 

 bv Fallen in his ' Specimen novam Hymenoptera disponendi 

 niethodum exliibens " of 181c5.
