1876.] MR. A. G. BUTLER ON THE GENUS TERACOLUS. 143 



I have compared our example with male specimens given to me 

 by Mr. Ansell, from Kinsembo, and find no difference. 



51. Teracolus lucullus. (Plate VI. fig. 4.) 



<S . Above very like the preceding species, but the internal streak 

 of primaries more defined, the base and costa of secondaries blackish, 

 terminating near apex in a black costal spot ; marginal spots of 

 secondaries more distinctly separated : wings below white, primaries 

 with the apical area sulphur-yellow, covered internally by a broad 

 orange patch (not so broad as in T. interruptus), through the centre 

 of which runs an angulated grey streak ; a black point at end of 

 cell ; a blackish spot on iuternal area ; secondaries tinted with pale 

 sulphur-yellow at apex ; basal half of costa orange, a blackish sub- 

 apical costal spot ; a black-and-orange dot at end of cell ; an angu- 

 lated brown marking on the disk, cut by the third median branch ; 

 a marginal series of black dots terminating the nervures. Expanse 

 of wings 1 inch 5 lines. 



$ , Teracolus loandicus (in part), Butler, P. Z. S. p. 724 (1871); 

 Lep. Exot. p. 91, pi. xxxiv. fig. 9 (1872). 



<5 , Ambriz, October 1872 {J. J. Monteiro, B.M.) ; $, Loanda 

 (cull. It. Meldola). 



I have no doubt that I made a mistake in referring the above 

 female to my T. loandicus, the differences between it and the female 

 of T. interruptus being precisely parallel to the differences between 

 the two males. T. loandicus will come into another section, in 

 which the females have the marginal spots of secondaries rather 

 small, the orange patch of primaries curved and not extending be- 

 yond the limiting streak, and an interrupted angular streak from 

 costa to internal area of secondaries. 



52. Teracolus gelasinus, n. sp. 



<$ . Nearly allied to T. interruptus, but readily distinguished by 

 the absence of the internal streak of primaries and the small mar- 

 ginal spots of secondaries : wings below white, the nervures termi- 

 nating in black dots, all the wings with black dots at the end of the 

 cells ; primaries with the apex broadly sulphur-yellow, bounded in- 

 ternally by a rather narrow orange band, on which are a few dusky 

 scales ; sometimes a small dusky spot near inner margin beyond the 

 middle ; secondaries speckled with brown, with the basal third of 

 costa orange, sometimes a small dusky spot on second median inter- 

 space. Expanse of wings 1 inch 4-7 lines.
