Pastazza and its forms speciosa and cxcelsa having a wholly 

 black club, while excelsior and its forms ockendeni, elatior 

 michaeli and excelsissimq have the apical half of the club 

 ochre yellow. This point of difference did not seem to have 

 been detected by Staudinger, who first described pastazza as 

 a form of excelsior, as he differentiated his pastazza by wing 

 colouring. The excelsior of llewitson, figured ft". 49, 50, 

 Cat. vii, appears to be, if not unique, excessively rare. As it 

 is close to excelsior elatior it might be found in the same 

 localities in Ecuador, notwithstanding the locality given, 

 " Amazon.*" Other races of excelsior are also rare — michaeli 

 from the Solimoes River and excelsissima from the Madeira 

 as well as elatior from Ecuador are all scarce, ockendeni alone 

 having been secured in some numbers in the Chanchamayo 

 district of Peru. In tabulated form the two species work out 

 thus : — ■
