of tlie primai'ies, which also unites with the hind-marginal line in both sexes. The 

 females also show the same characters and some forms show the orange line on the 

 apical area of the primaries. 



Mai,e. — Central area of the primaries creamy-white, the apical area and hind 

 margin heavily marlced with brownish-black ; a baud consisting of si.x orange spots, 

 more or less spear-shaped and somewhat pinker in colour than in T. daira, relieving 

 the black on the apical area ; the broad black line along the inner margin suffused 

 with grey near the base ; a white spot visible near the posterior angle ; the cilia 

 white at this point and not at the extreme apex. Secondaries with the central area 

 of tlie wing creamy-white ; the extreme base, costal margin and hind margin broadly 

 bordered with brownish-black, the latter only faintly streaked with white ; the cilia 

 white. 



Underside. — The general aspest of both wings similar to those of T. daira as 

 regards colour and markings, with the exception that all the markings are more 

 heavily indicated. 



Expanse 1"3 inches. {Spec, ex Rabai Hills, July lb89; F. J. Jackson Coll. Type 

 of T. Jacksoni.) 



Female. — Very similar to that of the male described above as regards the 

 brownish- black borders on both wings ; the orange spots on the apical area of the 

 primaries more of an orange- yellow colour than in the male, the ground-colour 

 sulphur-yellow instead of white, somewhat more reduced, and with a second spot 

 visible above the usual one at the posterior angle. 



Underside. — Very similar to that of the female of T. daira as regards colour and 

 markings ; the orange band and the black line along the inner margin, wider and more 

 heavily indicated ; the green shading also less yellow in colour. 



Expanse 1-2 inches. {Spec, ex Witu, May 1891 ; F. J. Jackson Coll.) 



A second form of the female, which I have figured, is very like the female of 

 T. daira (id) in the general colour of both wings. The brownish-black apical patch 

 on the primaries is somewhat larger, and the orange-red spots nearly obsolete ; a 

 very thin line unites the hind-marginal border to the darker inner-marginal line in 

 this form, this line being entirely absent in T. daira. The broad blackish border on 

 the secondaries somewhat more relieved with sulphur-yellow spots than in the female 

 (fig. lb). With the exception that the ground-colour is more yellowish-buff, the 

 spots and markings agree with those of fig. Ic. 



Expanse 1'3 inches. {Spec, ex Karanioi/a, November, Capl. Dicer ; E. M. Skarpe 

 Coll.). 



" Intermediate " form ok Male. — Very similar to the " wet-season " form, but 

 the primaries not quite so elongated, the black along the inner margin is not united
