24 SOUTH-AFKICAX BUTTERFLIES. 



labours in this and other most, difficult genera merit the thanks of all 

 lepidopterists. 



T. Butleri would appear to be a scarce species in South Africa, as the only 

 examples that have come under my notice are a few captured by myself on the 

 coast of Natal in February and March 1867.^ There was, however, nothing in 

 the habits of the butterfly to distinguish it from its congeners, and it is quite 

 possible that it may be passed over among the rest in the localities they all 

 frequent together.

$ Gamhogc-yelloiv ; fore-wing ivith a narrow or very narroiv black 

 border ; hind-ioing bluntly angulated at extremity of second median ner- 

 vidc, and with an extremely narrow black border, occasioncdly broken into 

 ncrvular sjwts. Fore-wing : on costa not far from base commences a 

 thin black edging, gradually widening beyond middle to a border of 

 variable width apically, which continues more narrowly along hind- 

 margin to posterior angle, where it again slightly widens ; inner edge 

 of border irregularly and bluntly dentate superiorly, but emitting 

 regular denticulations on median nervules and submedian nervure. 

 Hind-vnng : border little more than a slender edging-, rather strongly 

 dentated on nervules inwardly, diminishing to a point at extremity of 

 first median nervule or of submedian nervure ; rarely this border is 

 reduced to nerv^ular spots of modei-ate or even small size ; inner-mar- 

 ginal border conspicuously paler, quite sulphur-yellow. Cilia of fore- 

 wing greyish-brown mixed with rufous and at posterior angle with 

 yellow, — of hind-wing, yellow mixed with rufous. Under side. — 

 Sulphur-yclloiv, with pale-ferriiginous markings. Fore-vnng : apical 

 border rather widely tinged with pale-ferruginous, continued narrowly

 the country between the Transvaal and Gubulewayo, Matabeleland.
