primaries and rosy secondaries, showing traces of an angular discal series of dusky spots, 

 one or two of which are more or less prominent on the upper surface of the female ; 

 the apical patch in this sex is dark brown, with a curved sub-apical series of indistinct 

 orange spots." 



It will be seen that Dr. Butler unites T. lais and 7\ liahjallcfi together. They are 

 however, kept as distinct species by Dr. Trimen and Mr. Guy Marshall, and, as far as 

 the evidence goes, I am inclined to agree with the two latter Lepidopterists. 



Of the large variety a, Dr. Trimen writes: '"that four examples (two of each sex) 

 were taken by Col. Bowker on the Vaal River in 1871, but no note accompanied them 

 except the general one (since confirmed by Mr. Feltliam) that in that tract of 

 country all the TeracoU were almost confined to the immediate vicinity of the 



river.''

 primaries. The females are also much more heavily marked than in T. lais.
