ority over Macroglossapis ; but while I do not possess the earlier 

 paper, I saw it at the British Museum and made careful note of its 

 contents, while ray wife made copious extracts, and copied several 

 figures. We found no description of Thygater whatever, nor did 

 Dalla Torre, who cites all the species in this paper in his catalogue. 

 Schrottky also, in his catalogue of Argentine Hymenoptera (1903) 

 has no Thygater, though he cites Holmberg fully ; and there is no 

 allusion to the genus in Index Zoologicus.
