148 MR. A. G. BUTLER ON THE GENUS TERACOLUS. [Jan. 18, 



and apex of the first median nervule black ; apical area broadly deep 

 orange (almost vermilion), its internal edge bordered indistinctly by 

 black atoms ; a black dot at end of cell : secondaries with the apices 

 of the nervures black, a marginal series of grey spots terminating the 

 nervures. Primaries below white ; apical area creamy orange, 

 becoming clear and bright internally, crossed obliquely by a few 

 brown scales, and speckled with brown towards apex : secondaries 

 creamy whitish, with a feeble pink tint, densely reticulated, except- 

 ing just beyond the cell, with brown ; a black-and-o range dot at end 

 of cell, base of costa orange. Expanse of wings 2 inches. 



2 . Very like the female of T. halyattes, but much larger, the 

 apical spots of primaries above larger, the secondaries below with a 

 clear patch beyond end of cell, as in the male. Expanse of wings 

 1 inch 9 lines. 



Var. S • -Apical area of primaries below uniformly pinkish; the 

 secondaries also much more pink. Female with the internal streak 

 of primaries above expanded into a broad irregular blackish patch. 

 Expanse of wings, S 1 inch 8 lines to 2 inches, $ 1 inch 9 lines.

This is probably Trimen's Anthocharis antevippe, but not Bois- 

 duval's,

 Allied to T. deidamia. 



71. Teracolus simplex, n. sp. 



S . Wings above white : primaries with a very oblique triangular 

 orange apical patch, bordered narrowly on its costal and external 

 edges with pale brown ; a minute black dot at end of cell. Primaries 

 below white, with the apical area ochraceous, indistinctly speckled with 

 brown ; a black dot at end of cell : secondaries pale rosy whitish, 

 reticulated with reddish brown ; base of costa reddish ; a pale-yellow- 

 and-black dot at end of cell ; a few brown atoms congregated below 

 the costa near apex. Expanse of wings 1 inch 10 lines. 



D'Urban ( Capt. Shelleij) . Type, B.M. 



This species is readily distinguished by the absence of grey scaling 

 at the base, the indistinctness of the outer border of the primaries, and 

 the very oblique inner edge of the orange apical patch.
