220 Mr. A. G. Butler on the Genus Terias. 



Terias hecabe group. 



The external border of primaries broad and deeply bisinu- 

 ated in both sexes ; certain Japanese examples of T. Mariesii^ 

 however (apparently influenced by crossing with T. atiemone), 

 have the border as in the T. asiope group. The following 

 are in the Museum : — 



T. Mari'esiz, Butl. ; T. Jiecabe, Linn. ; T. nicohariensis^

Terias hecabe, Linn. 



This species was originally described from a Chinese speci- 

 men ; it, however, ranges, without any variation worth men- 

 tioning, from the north of India to northern Australia. The 

 sexes differ chiefly in tint, the male being of a deep gamboge- 

 or even dark chrome-yellow, the female varying from primrose- 

 to lemon-yellow. In both sexes the outer border of the 

 secondaries is narrow and well defined. 



Terias johanospila, Felder, 



This is the T. hecabe of Horsfield's Catalogue, the larva 

 and pupa of which are figured by him. The larva is said to 

 feed on j^schynomene sesban and to be found abundantly from 

 January to April. Typical T. hecabe, from Ceylon, is said to 

 feed " on Leguminosa3 " and on the " Madras thorn." 



That the above is distinct from T. hecabe I have no doubt; 

 not only is it a larger insect, the male in pattern approaching 

 that sex of T. cesiope, both sexes on the under surface also 

 resembling the latter, but the colouring of the upper surface 

 (as described by Felder) is of a deep (ochreous) yellow, 

 showing in certain lights a lilacine gloss. 



Terias excavata, Moore. 



This species has frequently been mistaken for T. cesiope, 

 from which it is perfectly distinct ; we have a series of 

 seventeen from Kangra, Cachar, Bombay, Assirghur, Poona, 

 Mhow, and Suttara, most of which were presented to us by 

 Colonel Swinhoe, 



Terias hecabeoides, Mendtrids. 



Described and figured from a male taken in the N.W. 

 Provinces of India and sent to M^n^tries by Mr. Field ; it is
