taken near D'Urban by Mr. Millar, with the type of A. pseudo-zeritis, I have 
come to the conclusion that Esmeralda is identical with Pseudo-zeritis. The 
type of the latter is considerably worn, and the metallic spots on its under side 
are more brassy than silvery, while the fulvous-yellow tinge over the disco- 
cellular and costal part of the fore-wings is more pronounced, and there is pro- 
nounced brownish fuscous clouding over both basal and lower discal areas of 
the hind-wings. Mr. Selous' two examples have on the under side a paler 
ground-colour, Avholly wanting any dusky clouding. The D'Urban specimens, 
on the contrary, are beneath of a darker greyer tint than the others, presenting 
also a small but very pronounced fuscous cloud on the middle disc of the hind- 
wings, and having all the silvery spots very brilliant. The greenish hue 
which replaces in certain lights the blue of the upper side is Avell exhibited in 
all the specimens except the type of Pseudo-zeritis. There are two linear tails 
on the hind-wing, respectively on the first median nervule and the submediau 
nervure — the latter tail being the longer of the two. 
It has been rightly pointed out by Mr. Butler that the subcostal nervure 
of the fore-wings has only three nervules, instead of four (rarely five) as in 
Aphnceus ; but this is the only important feature of his new genus Chloroselas, 
approximating it to CJirysorijchia. The butterfly under notice is, however, 
much less robust in structure than Chrysorychia, and has much longer and 
more hirsute palpi ; and it is on the whole so thorough an Aphnceus that I 
hesitate to separate it generically on account of its wanting one branch of the 
subcostal nervure of the fore-wings. 
In December 1887 Mr. Millar had the good fortune to fall in with this 
exquisite little species near D'Urban. He wrote to me that he took about a 
dozen examples "flying round acacia trees at Clare Estate, Sydenham. They 
perched both on twigs and leaves, from which they darted at one another, and 
were very swift on the wing, usually returning to the same spot. They had 
not, so far as I am aware, been seen before near D'Urban."

The specimens received from Mr. Palmer are noted as having been taken 
on 14th March and 17th April 1888; they were settling on grass and low 
plants about " kopjes," on a stony ridge.

It gave me great pleasure to receive three ^ s and a 9 of this very rare 
species from Mr. Hutchinson in February 1 888 ; and I am thus enabled to 
supplement my description of the solitary specimen previously known to me in 
the following particulars, viz. : —

It is clear, on comparison with the 9 received from Mr. Hutchinson, that 
the smaller example described in the text is also of that sex. The larger 9
