1876.] MR. A. G. BUTLER ON THE GENUS TERACOLUS. 141 



connected by a greyish internal streak with the base ; secondaries 

 with the marginal spots occasionally larger, and a dusky ill-defined 

 spot on the second median interspace : primaries below with the 

 apical area dull lemon-yellow, bounded internally by an angulated 

 brown line, followed by and edging a broad orange streak ; secon- 

 daries sandy whitish, irrorated sparsely with brown, a congregation 

 of brown scales on the costa near apex, and an ill-defined streak 

 across the median branches ; costa at base orange, a black and orange 

 point at end of cell. Expanse of wings 1 inch 4-7 lines. 



5 . Sulphur-yellow above, base slightly greyish, internal area of 

 primaries grey, darkest at base and in a spot beyond the middle, 

 where it terminates ; outer margin bordered by brown triangular 

 connected spots, the apices of the nervures also brown ; a narrow 

 angulated discal brown streak halfway between the cell and apex ; a 

 minute black point at end of cell ; secondaries with a marginal series 

 of brown spots, a lunular subapical spot on subcostal interspace ; a 

 squamose brown discal streak across the median branches : wings 

 below with the base of primaries yellow and the secondaries slightly 

 darker; otherwise as in the male. Expanse of wings 1 inch 3 lines. 



Between Natal and Delagoa Bay (4 examples, E. C. Buxton). 



Type, B.M. 



This is a well-marked little species, easily distinguished by the 

 coloration of the under surface. 



47. Teracolus ly^eus, n. sp. (Plate VI. fig. 2.) 



c? . Wings above white, base greyish black, base of costa, head, 

 palpi, and prothorax pinkish ; centre of costa of primaries markedly 

 black ; apex orange, sharply cut, with lilacine reflections ; outer 

 border to first median branch black, strongly sinuated between the 

 veins, whose apices are also black ; a well-defined rounded black spot, 

 touching the third median brancb, upon the second median inter- 

 space ; fringe, excepting at external angle, rosy ; an ill-defined in- 

 ternal pale grey streak, slightly darker at its extremity ; secondaries 

 with a marginal series of black spots, more or less triangular ; fringe 

 rosy at anal angle : primaries below with the apical area chrome- 

 yellow, irrorated with grey and cut by an angulated orange streak ; 

 fringe and costa as above ; secondaries rosy, irrorated with grey ; a 

 dusky subapical spot, and a second on second median interspace; an 

 orange-and-black discocellular point ; costa deep orange. Expanse 

 of wings 1 inch 4 lines. 



$ . White above, with the apex of primaries yellow and the costa 

 rosy ; base yellow, irrorated with grey ; primaries with apical 

 markings, as in the preceding species, but broader ; a greyish ill- 

 defined internal streak, terminating in a brown spot ; secondaries 

 with a marginal series of large brown spots, a brown subapical spot, 

 and a W-shaped discal marking cat by the third median branch : 

 wings below as in the male, but rather paler. Expanse of wings 

 1 inch 4 lines. 



Between Natal and Delagoa Bay (3 examples, E. C. Buxton).
