The last named authors consider this one subgenus but Daniel 

 treated it as two, Magdalis (type violaceus), and Magdalinus (type 

 armigera), and subdivided Magdalis into two groups with violacea 

 Linnaeus and frontalis Gyllenhal as tj^pes. 



The first group is therefore Magdalinus Schonherr (type 

 violaceus'), synonymy: Thamnophilus Schonherr, Magdalis Daniel 

 group 1. 



The second group is unnamed, type frontalis. 



The third group is Magdalis Germar, (type aterrima), syn- 

 onymy: Magdalinus Daniel.
