H. acrisa was described from the extreme wet form of the 

 male, in which the under surface of the wings is white. A 

 second (perhaps later) wet form has the apex of the primaries 

 and whole ground-colour of the secondaries sulphur-yellow. 

 The intermediate form has the same parts sordid bufT- 

 brownish, with the dark markings less pronounced, and, 

 finally, the dry form (H. terranea) has these parts earthy 

 brown. Owing to the acquisition of five examples, including 

 two females, in the Godman and Salvin series, we now have 

 all the phases ; previously we only possessed males of the 

 extreme types — B. acrisa and terranea. 



Tachyris maculata, Grose-Smith, seems nearly allied to 

 this, but I have not seen the type. 



3. Huphina perimale.

The wet phase, with yellow under surface to secondaries, 

 is in the llewitson collection ; IJ. amarella is the female of 

 the intermediate phase, and typical H. perimale, with deep 

 earth-brown under surtace to secondaries, is the dry phase. 

 In the females the width of the black borders above varies 

 seasonally, being least developed in the dry form.
