93. Teracolus pseudocale, n. sp. (Plate VI. fig. 9.) 



c? • White above, the base grey ; primaries with the apical two- 

 fifths black, enclosing a large, reddish, orange, arched band, divided 

 by the nervures into six parts ; a minute black dot at end of cell ; 

 secondaries with a marginal series of six large triangular black spots : 

 wings below white, base yellowish ; primaries with the apical area 

 creamy yellow, bounded internally by a large, curved, diffused, orange 

 patch, a black dot at end of cell ; secondaries with a black-and- 

 orange spot at end of cell. Expanse of wings 1 inch 6-10 lines. 



$ . Wings above white, basal two fifths grey, obliquely in prima- 

 ries, and terminating at second third of internal nervure in a darker 

 grey spot ; apical third black, inclosing a curved, orange band, divi- 

 ded by the nervures into five parts ; secondaries with well-developed, 

 interrupted, angulated, blackish streak and 5 decreasing, triangular, 

 marginal spots : primaries below nearly as in the male, secondaries 

 pale yellow, with ochreous discal streak and a black dot at end of cell. 

 Expanse of wings 1 inch 5-10 lines.

94. Teracolus angolensis, n. sp. 



3 • Closely allied to the preceding, but the apical patch wider 

 upon the costa and continued in the form of a tapering costal 

 border nearly to the base ; orange patch half as wide again, its inner 

 black border tapering towards the costa; marginal spots of secondaries 

 more pyramidal and consequently separated : wings below destitute 

 of yellow colouring, the diffused orange patch of primaries broader. 

 Expanse of wings 1 inch 9 lines. 



$ . Wings above white or yellow, markings as in the preceding 

 species ; but the orange band broader, the greyish areas darker, the 

 border and band of secondaries much more pronounced, and the 

 undersurface more uniform in colour. Expanse of wings 1 inch 7- 

 10 lines.

 Seems allied to the preceding species.

spots.
