and brighter colour, the costa of primaries, base, and abdominal area 

 of secondaries much less strongly suffused with grey ; the black dis- 

 cocellular spot of primaries more conical in shape ; the outer blackish 

 border terminating abruptly upon the first median branch, the margin 

 alone being black ; the black spot on interno-median area smaller and 

 not connected with the outer border ; six discal spots of the ground- 

 colour running in a curved series through the centre of the border, 

 the first four large, placed in pairs, the last two small and well 

 separated ; six submarginal smaller spots, the two at apex elongated ; 

 secondaries with five large diamond-shaped brown spots at the end 

 of the nervures, the upper three united iuto an apical marginal band ; 

 the last of these spots ill-defined on a gi'ey ground at end of second 

 median branch ; the first median and internal nervures also terminate 

 in diamond-shaped grey spots ; three small black spots on the disk, 

 above the median nervures ; costal area, excepting at apex, broadly 

 black : wings below nearly as in T. dynamene, but clearer in colour, 

 with a suffused orange patch over the median nervure. Expanse of 

 wings 1 inch 5 lines.

This species is of the size and form of T. amata, but can readily 

 be distinguished by the orange patch below, which is more strongly 

 developed than in any other species ; the female has the disk and 

 external spots of the primaries and the whole of the ground-colour of 

 secondaries whitish. Cramer confounded the African species with the 

 insect from Coromandel, which he figured under the same name in 

 his fourth volume. 



8. Wings white or sulphur-yellow, spotted or banded above with 

 black or grey, the apex of primaries invariably orange in the 

 males, generally black in the females with a central orange, 

 yellow, or white macular band ; this band, however, is occa- 

 sionally absent, leaving the apex wholly black, Callosune,

8 a. Orange apical patch of the male without an internal black 

 edge, interrupted internally on second median interspace by a 

 transverse black spot. Typical form, T. interruptus.

<3 . Very like T. interruptus, but with no internal blackish streak 

 on the primaries, with the black outer border of the orange patch 

 narrower, the inner spot small ; the inferior extremity of the orange 

 patch not enclosed by a black expansion of the border ; secondaries 

 with the marginal spots small : primaries below white, the apical 

 area clay-coloured speckled with grey and bordered internally by a 

 dull orange diffused streak ; secondaries pale buff, densely irrorated
