This fine species was discovered in Ecuador by Mr, 

 Warszewicz, to whom we are indebted for many new species^ 

 of humming birds, chiefly from 'Colombia, Ecuador, Bolivia, 

 Veragua, etc. Being sufficiently distinct in generic forms 

 from Heh'otrypha, I have made with it a new genus, which I 

 have named Warszewiczia, in memory of that eminent Collector 

 and Naturalist.
