204 SOUTH-AFRICAN BUTTERFLIES. 
on reference to Kew, by Mr. J. Medley Wood, Curator of the Botanic 
Gardens, D' Urban.) ' 
Pupa. — Flattened dorso-abdominally ; thoracic dorsal projection 
much prolonged, pointing forward and upward, and extending as far | 
forward as, or even a little farther than, the head ; cephalic promi- j 
nences short, acute, widely apart ; lateral margin with two small acute i 
projections, one behind the other ; a little beyond these, abdominal 
margin considerably expanded laterally (almost foliated). ; 
Bright pale-green ; roughened lateral edge of dorsal projection down j 
to lateral abdominal expansion, median frontal line of that projection, 
and cephalic and thoracic lateral margin, all creamy-ferruginous, 
which tint forms an irregular lateral patch where edges of base of 
dorsal projection and those of thorax meet ; two spots of the same 
colour on back of abdomen (third segment) ; spiracles superior, fuscous.

I obtained twelve Policenes (six of each sex) from pupse sent by 
Colonel Bowker from D'Urban, Natal. They reached Cape Town on 
30th November 1878, and the butterflies emerged during the succeed- i 
ing fortnight, with the exception of one which did not make its 
appearance until 12th February 1879. Seven of these had the date 
of their becoming pupre attached, and I was thus able to record that 
(with the exception just noted) the chrysalis state lasted from seven to 
fifteen days. All these pupte were suspended to leaves, in a position 
near the mid-rib.^ 
I have not seen P. Nyassce, Butler {Ann. and Mag. JSfat. Hist., 1877, 
p. 459), from Lake Nyassa, but it is described as intermediate between 
Policenes and Antheiis, and, from the particulars given by the describer, 
appears to be nearer to the latter than to the former. 
I was unfortunate as regards meeting with this Papilio during my sum- 
mer stay in Natal. I had previously observed a specimen flying rapidly near 
D'Urban on the 4th August 1865, and looked forward to obtaining many other 
examples in 1867, but only once (on 20th February) came across a solitary 
individual, which evaded my attempts to capture it. This example looked very | 
green on the wing ; it flew swiftly, but settled twice on damp sand. Mr. W. 
D. Gooch (Entomologist, 1880, p. 230) notes that the butterfly is common, ! 
especially in November and December, and " can be taken freely, sipping the j 
moisture from damp mud on the margins of rain-pools in the sandy paths near i! 
bush, all along the coast." Most of the specimens received from Colonel Bowker « 
were taken in the months mentioned, but he sent one pair in copula on 5th 
April 1879. The latter are unusually small, the ^ expanding only 2 in. 7 
lin. and the 9 3 in. 2 lin. 
^ The figures purporting to be those of the larva and pupa of Policenes which are given 
by W. W. Saunders (from R. W. Plant's drawings of Natal specimens) in Trans. Ent. Soc. 
Land., 2nd Series, iv. pi. 13, ff. a, b, c, 1857, unquestionably illustrate the earlier stages 
of another Papilio — either P. Demoleus or a near ally.
