70. Terias ajrricaj sp. n. 



<$ . Upper surface as in the preceding species ; gamboge- 

 yellow : primaries with slender black costal margin : apical 

 area black-brown, commencing at apical third of costa, its 

 inner edge oblique and concave, with four shallow sinuations, 

 terminating in a nearly right angle upon the third median 

 branch; external border rather narrow, bi.sinuated on the 

 median interspaces, below which it expands abruptly, becoming 

 as wide as the lower edge of the apical area : secondaries with 

 slender greyish margin and small black spots at the extre- 

 mities of the veins. Wings below lemon-yellow, with faint 

 traces of the usual dark brown markings on the basal half, 

 but with no trace of the sigmoidal subapical streak of T. sul- 

 phurata] marginal points extremely minute. Expanse of wings 

 42 millim.

This species is slightly larger than the preceding, from 

 which, however, it may chiefly be distinguished by the almost 

 immaculate under surface and the total absence of the charac- 

 teristic subapical sigmoidal streak on the under surface of the 

 primaries ; it belongs in fact to the same group with T. hecabe, 

 and not with T. cesiope. 



71. Terias vallivolans^ sp. n. 



Bright lemon-yellow ; primaries with the costal margin 

 very narrowly black ; apical area commencing at about the 

 apical third of costa, its inner edge iuangled and irregular, 

 terminating in a rectangle on the third median branch ; outer 



border upon the median interspaces narrow, unevenly bisinua- 

 ted, expanding below the first median branch, but not very 

 greatly, and notched just above the submedian vein : secon- 

 daries with a narrow, abbreviated, tapering, internally sinuated 

 external dark brown border, commencing at the extremity oi 

 the first subcostal branch, but barely traceable beyond the 

 second median branch. Under surface slightly paler ; margin
