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

 fig. 2 (1835).

 Caffraria. B.M. 



Wallengren, in his ' Lep. Rhop. Caffr.,' has confounded this species 

 with T. omphale ; the two females are much alike. M. Lucas's 

 figure is not quite correctly drawn and is over-coloured ; but there is 

 no mistaking the species intended. 



85. Teracolus suffusus, n. sp. (Plate VI. fig. 10.) 



5 . Very like a small female of T. omphale, but the basal area of 

 the primaries grey to costa, the subapical orauge spots smaller, and 

 the angular band of secondaries considerably narrower : wings below 

 creamy white ; secondaries with a distinct yellowish tint ; primaries 

 with a large, subapical curved, orange patch, leaving a narrow, sordid, 

 yellow, apical border ; secondaries with an angulated discal streak 

 (its upper half ill defined) testaceous ; a black-and-orange spot at 

 end of cell. Expanse of wings 1 inch 4 lines. 



Ambriz {J. J. Monteiro). Type, B.M. 



This very distinct little species is a link between the T. -omphale 

 and T. -epigone groups. 



86. Teracolus hybridus, n. sp. 



d $ • Above like T. omphale, below like T. omphaloides, but the 

 secondaries of a more rosy tint, such as occurs in T. theogone. Ex- 

 panse of wings, J, 1 inch 9 lines, $, 1 inch 10 lines. 



5 , Plettenberg Bay ; $ , Natal. Type, B.M. 



This may be the result of a cross between T. omphale and T. om- 

 phaloides ; it, however, clearly approaches T. theogone in the colora- 

 tion of the under surface. Although species of the same genus are 

 frequently known to make matrimonial mistakes, it is doubtful whether 

 in such cases the females are often fertile. 



87. Teracolus theogone.

 The sexes of T. theogone were taken in copula 1 by Mr. Buxton.
