On the Plerine Butterflies of the Genus Catophaga. 

 By ARTHUR G. BUTLER, Ph.D., F.L.S., F.Z.S., &c. 



[Concluded from p. 401.] 



Group 4. TACHYRIS, Wall. 



The largest group in the genus, containing species of 

 tolerably uniform outline, though differing considerably in 

 coloration : the first and most typical species resemble the 

 earlier forms of Saletara in the coloration of the males, 

 whilst their females much more nearly resemble those of 

 Catophaga ; then we meet with a series of bright scarlet or 

 orange insects, gradually changing to species with the upper 

 surface white and brown-bordered. In nearly the whole of 

 the species the dark outer borders on the under surface of the 

 wings are regular in outline, and in most of the white species 

 the seasonal forms seem to be characterized by the width of 

 these borders in the males and the amount of white on the 

 upper surface of the females, the dry-season males having 

 narrower borders and the dry-season females being marked 

 with broad white patches *.

 as I believe it to be a Huphina near to H. acrisa.
