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

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

 second (]:)erhap3 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 buff- 

 brownish, with the dark markings less pronounced, and, 

 finally, the dry form {II. 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 ])hascs ; previously we only possessed males of the 

 extreme types — 77. acrisa and ierranea. 



Tacliyris moculata^ Grose-Smitli, seems nearly allied to 

 this, but I have not seen the type.

The wet ])hase, with yellow under surface to secondaries, 

 is in the Ilevvitson collection ; 77. amareUa is the female of 

 the intermediate phase, and typical //. 'perimale, with deep 

 earth-brown under surlace 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.
