This species, as far as I have been able to determine from specimens, appears to 

 range from the Grahamstown District in the Eastern Cape Colony to Natal {T. eris, 

 Trimen, S. Afr. Butt. iii. p. 97) and thence to Zululand and the Transvaal, where 

 Mr. Distant met with it near Pretoria {T. eris, Distant, " A Naturalist in the 

 Transvaal," p. 234, 1892), thence northwards to Matabeleland (T. eris, Westwood, 

 Oates, "Matabeleland," App. p. 336, 1881) and the Manica country {T. eris, 

 Trimen, P. Z. S. 1894, p. 65). As, however, I have not seen specimens from the 

 last named localities, I am unable to determine as to whether they are really 

 T. johnstoni or referable to T. opalescens. A subsequent examination may prove that 

 some of them are T. opalescens. The geographical range, however, of T. johnstoni 

 seems to be quite natural, and I shall await the confirmation of the distribution 

 which I have here assigned to it. 



Of the T. eris group of the genus Teracolus, Dr. Butler recognises four species, 

 while Mr. Guy Marshall and Dr. Trimen admit but one. The variation in colour of 

 the female, in this section of the genus, is certainly somewhat extreme, and the series 

 which I have examined in different collections has not been sufficient for me to give 

 the exact geographical distribution of the forms admitted by Dr. Butler. 



Nevertheless, I have considered it best to follow Dr. Butler's arrangement of this 

 group in the British Museum, and I therefore quote his remarks as follows ; " Ranges
