This fine species was discovered in Ecuador by Mr. 

 Warsze\\ icz, 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 Heliotrypha, I have made with it a new genus, which I 

 have named Warszeiviczia, in memory of that eminent Collector 

 and Naturalist.
