280 THE ENTOMOLOGIST. - 
often watched them, to discover, if possible, where I might look 
for the larva with success. ; 
The two common insects P. Demoleus and P. Nireus are very 
abundant, and they may soon be.bred by searching the orange- 
trees for the larve, which are fairly abundant in both cases if you 
happen to hit on a favourite breeding place. 
P. Merope, according to Dr. Seaman, who first called my 
attention to it, is more strongly and deeply barred at one season 
than the other, the dry weather of winter making lighter imagos 
than those bred and developed through the hot damp summer, 
As Mr. Spiller remarks, many of the Anthocharine are similarly 
affected, notably the vars. A. Keiskamma and Evarne, as also 
several other common species. 
The question of the mimicry of the Danaide by the female 
P, Merope has been fully dealt with by Mr. Trimen in several 
papers, 
Next in order come P. Antheus and P, Policenes, very closely 
allied ; the former so rare as to have been sometimes considered 
almost doubtful; the latter common enough, especially immedi- 
ately after the early rains and the first heats of summer—in 
November and December, when, as Mr. Spiller says, they can be 
taken freely, sipping the moisture from damp mud on the margins 
of rain-pools in the sandy paths near bush, all along the coast; but 
they become more rare as you reach the higher ground inland. 
The transparent greenish tint of P. Policenes, with its black 
bars and long delicate tails, make it a very pleasant imsect to 
take and very difficult to get perfect without spoiling the tails. 
In the summer of 1878—79 the larve and imagines of this insect, 
as well as those of P. Pylades and P. Leonidas, were collected in 
considerable numbers at Durban by Colonel Bowker and by 
Mr, Philip Payne. They occurred on the young shoots from 
roots of trees that had been cut down in clearing out the bush to 
make the park near Durban... The transformations were care- 
fully noted, and specimens sent down to Mr. Trimen for 
description, soon to be forthcoming. The larva of P. Antheus 
must certainly be rare, and is, so far, unknown. That of 
P. Leonidas had already been worked out by Dr. Seaman, 
of Pine Town, and by myself on the coast. The pretective 
form and colouring of the pupe and larve of all these 
insects is most perfect. P. Leonidas himself is a very hand-
