This species is not represented in the McOonnell. collection, and 

 the, above description is taken from the type of the species which 

 is in the British Museum, and was collected by the late Henry 

 Whitely at Mount Roraima, 3500 ft., November 29, 1883, 

 Salvin-Godman collection. 



This species difEers from T. fulignosa fulignosa (Wied) in its 

 paler coloration generally, but more especially on the under 

 surface. Whether T. fumosa (Lawr.) differs from the present 

 species I am unable to say, as I have not seen an example from 

 Trinidad whence he described it.
