18/6.] MR. A. G. BUTLER ON THE GENUS TERACOLUS. 157 



105. Teracolus WALLENGRENII, 11. sp. 



Anthopsyche eupompe, Wallengren (nee Klug), Lep. Rhop. Caffr. 



This species has three varieties, differing chiefly in size ; it is 

 easily distinguished from T. cinerescens by the narrower black edging 

 of the apical crimson or carmine patch of the male, the much more 

 yellow apical patch of the female, the restriction of the grey colouring 

 to the base of the wings, the small size of the marginal spots of 

 secondaries, and the deep reddish buff colouring of the under surface 

 of the secondaries and apex of primaries below. Expanse of wings, 

 J 1 inch 4 to 1 1 lines, $ 1 inch 5 to 9 lines. 



N.E. of Natal (14 specimens, E. C. Buxton). Type, B.M. 



This has, I suspect, been confounded with the Indian T. danae; 

 the latter, however, is more like T. cinerescens, its female having 

 the aspect of a very dark form of T. dedecora.

107. Teracolus dulcis, d. sp. (Plate VII. fig. 13.) 



3 . Smaller than T. danae, the crimson apical patch narrower and 

 with narrower internal black border ; basal grey suffusion not so 

 dark ; black marginal spots of secondaries small, and consequently 

 widely separated ; wings below altogether paler than in T. danae, 

 the spots fewer and smaller ; no black spots at external angle of 

 primaries. Expanse of wings 1 inch 7 to 9 lines. 



$ . Differs from the female of T. danae in its altogether paler 

 colour ; with darker apical patch, restricted within the angulated 

 transverse postmedian series of black spots, all the black spots much 

 smaller, the marginal spots of secondaries well separated. Expanse 

 of wings 1 inch 6 to 1 1 lines. 



c? $ . Kattywur (coll. F. Moore) ; tf, N. India (B.M.) 



Far. The female paler at base of wings, with the disk of secondaries 

 immaculate.

This species generally stands in Indian collections as the T. eupompe 

 of Klug. 



108. Teracolus dirus, n. sp. (Plate VII. fig. 11.) 



$ . Allied to the preceding and to T. pseudacaste. Wings above 

 white, the base broadly dark grey ; an irregular series of black spots
