of the secondaries in place of the minute black dots observable 

 in T. aspJiodelus, Expanse of wings 31-38 millim. 



Bombay and Poona {Col. Sivinhoe). 



The duplicate specimens in Col. iSwinhoe's collection were 

 labelled whilst still unset, and had never been subsequently 

 critically examined by him. So far as I remember, his private 

 collection was, with very few exceptions, correctly named, and 

 the species represented by typical specimens. 



Terias simplex, sp. n. (PI. V. fig. 2.) 

 Terias fimhriata ? , Moore, P. Z. S. 1882, p. 253. 



? . Allied to T. apicaUs ; sulphur-yellow ; primaries with 

 an oblong black patch at apex, its inner edge oblique and 

 tapering to a point along the costa, confluent in front with a 

 narrow black marginal border, the inner edge of which shows 

 scarcely a trace of sinuation • fringe grey, with a yellow basal 

 line : secondaries with a marginal series of black dots, fringe 

 a little paler than in the primaries ; abdominal border white : 

 body greenish. Under surface as in T. apicalis, the spots at 

 the end of the cells being shorter and more suffused than in 

 T. fimhriata. Expanse of wings 41 millim. 



Kangra, North-west Himalayas {Hoching), 



Excepting in its yellow colour and superior size the upper 

 surface of this species bears considerable resemblance to T. 

 gnathene from the New World ; the female of T. Jimhriata 

 would be much larger and more like the male in pattern. 



Terias senegalensis group. 



Linked to the preceding and succeeding groups, but differ- 

 ing from the former in the wider apical portion of the outer 

 border of primaries and from the latter in the usually narroAver 

 or entirely aborted posterior portion of this border. We have 

 the following named forms : — 



T. Boisduvaliana^ Mab. ; T. hrenda, Doubl. ; T. silhetana^ 

 Wall. ; T. hisinuataj Butl. ; T. chalcomiceta^ Butl. ; T. denti- 

 limhata, Butl. ; T. rotundalis^ Moore ; T. purreea^ Moore ; 

 T. suava, Boisd. ; T. vallivolans, Butl. ; T. Beiosherij Butl. ; 

 T. senegalensis, Boisd. ; T. decipiens, Butl. 



Terias Boisduvaliana, Mabille. 



We have this species from Ashanti, West Africa (probably 

 Camaroons), Fernando Po, and the island of Johanna; it 

 varies not a little in size, and entirely resembles T. hrenda 

 upon the upper surface. The species described by Mabille
