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



black dot at end of cell ; secondaries with small black spots termi- 

 nating the veins, base blackish : primaries below with the costa 

 rosy brownish ; the apical area dull sandy ochraceous, irrorated 

 with brown ; a black dot at end of cell ; secondaries sandy with a 

 rosy tinge, irrorated with brown ; a squamose subapical costal spot, 

 and an ill-defined streak across the median branches, brown ; base 

 of costa orange, a black-and-orange dot at end of cell. Expanse of 

 wings 1 inch 2-5 lines. 



5 . White or sulphur-yellow above, base grey ; primaries with the 

 costa rosy, an internal grey streak, terminating at second third of 

 wing in a transverse irregular blackish litura, which almost meets a 

 spur from the apical area ; the latter black, deeply notched inter- 

 nally, enclosing an oblique series of spots, four or five in number, 

 orange, yellow, or white ; the inner edge of the apical border 

 bounded with orange in the orange-spotted form, and with an orange 

 tint in the yellow-spotted form : secondaries with the cell and basal 

 half of the interno-median and first median interspaces grey ; a more 

 or less defined angulated discal black streak thence to the costa ; a 

 marginal series of tolerably large black spots. Primaries below white 

 or pale yellow, the bases broadly sulphur-yellow ; apical area sandy 

 or yellowish ochraceous, irrorated with brown and bounded by a pale 

 orange or bright yellow nebulous streak enclosing a macular brown 

 streak ; a bisinuate brown litura, cut by the first median branch ; a 

 black dot at end of cell : secondaries as in the male, excepting that 

 the subapical spot aud discal streak are united into an angulated bar. 

 Expanse of wings 1 inch 5-8 lines.

66. Teracolus ithonus, n. sp. (Plate VI. fig. 7.) 



cJ . Wings above white, blackish at base : primaries with a large 

 triangular reddish-orange apical patch, not excavated, but notched 

 internally, a few brown scales along its inner border ; apical portion 

 of costa and outer margin to first median nervule black ; the mar- 

 ginal border dentate-sinuate, and throwing off long spurs along the 

 nervures, but not completely separating the apical patch ; a minute 

 black dot at end of cell : secondaries with a series of six black mar- 

 ginal dots. Primaries below white, the apical area lemon-yellow, 

 irrorated with grey ; a black dot at end of cell : secondaries sandy 

 whitish, strongly reticulated with brown ; a black dot at end of cell ; 

 base of costa orange. Expanse of wings 1 inch 9 lines. 



5 . Very like the females of the preceding species, but with all the 

 black portions of the wing much less pronounced, the grey internal 

 streak of primaries pale and ending in a distinct dark spot (not in an 

 irregular transverse litura) ; the apical spots larger ; the undersides 

 of secondaries more evidently brown-speckled. Expanse of wings 

 1 inch 5-8 lines.
