Addendum 



A paper by Adolpho Ducke, entitled 'Enumeia^ao dos Hynieiiop- 

 teros colligidos pela Commissao e Revisao das especies de abelhas do 

 Brazil,' Commissao de Linhas Telegraphicas Estrategieas de Matto 

 Grosso ao Amazonas (Publicagao No. 35), Annexo No. 5, Historia 

 Natural, Zoologia, was received in October 1920, although it is dated 

 1916. It chiefly concerns the Meliponidse but, as our paper was then in 

 page proof, we could not include his somewhat drastic changes in 

 taxonomy. 



Prof. Cockei-ell has written from London as follows. "I have found 

 in the British Museum the type of Ancyloscelis ursinus Haliday, and 

 it is the genus we have as Leptergatis (armatus Smith). Ancyloscelis 

 is the proper name for this genus. Leptergatis halidoides Holmberg is 

 also in the Museum and is not congeneric with the above; it is very 

 near Melitoma." Unfortunately, this also was received after our pap)er 

 was in page proof. Furthermore, in justice |o Prof. Cockerell, it shoukl 

 be said that none of the proof has had the benefit of his revision.
