exoleta from Woodford. Lepidoiuera exhibited. — Mr. Bayne exhi¬ 
bited single specimens of Lasiocampa quercus from Norfolk, the 
New Forest and Epping Forest, for comparison. Eubolia cervinaria 
from Broxbourne ; a small indistinctly marked aberration of Luperina 
testacea from Broxbourne; Melanippefluctuata and Huwia luteolata, taken 
on Sept. 15th. He suggested that these might be 3rd broods. Papilio 
polytes and its varieties. — Mr. Edwards exhibited specimens of 
Papilio polytes and its varieties, and closely allied species, to illus¬ 
trate bis paper. Hemiptera and Diptera. —Mr. Jennings, on behalf 
of Mr. Clark : a box of insects of various orders, the most interesting 
of which, perhaps, were Acanthosoma tristriatum (Heteroptera) and 
Spilomyia speciosa (Diptera), upon the former of which Mr. Jennings 
made some remarks. Other interesting insects in the box were, Ledra 
aurita (Homoptera) and Hippobosca equina, the “ New Forest fly.” 
Coleoptera from W. Wickham . — Mr. H. Heasler exhibited Amphi- 
cyllius globus, Acalles ptinioides and A. turbatus, all taken in dead leaves 
at West Wickham, last September. 
Papilio polytes : its varieties and allies. —Mr. Edwards read a 
most interesting paper on the facts connected with the polymorphic 
species, Papilio pammon, L. $ = polytes, L., 2 ; its variation, sub¬ 
species, races and geographical distribution. He said it is more or 
less distributed over the four divisions of the Oriental region and the 
Austro-Malay division of the Australian region. In each part of its 
range we find a different form of the 2 predominating, and resembling 
in flight, habit, and general colouring, some very common species of 
Papilio, which is protected from the attack of lizards, birds, etc.., by 
its acrid juices. This variation is confined to the 2 s. Each par¬ 
ticular 2 produces not only 2 s like herself, but the other 2 types 
as well, and the types are remarkably definite and constant. He then 
gave a classified list of the various forms as follows:— 
I. Continental. — 1. Tailed $ and tailed $ .— P. pammon $ , India, 
Malacca ; P. pammon 2 , India, China, Ceylon ; P. polytes 2 , India 
(mimics, P. aristolochiae ) ; P. romulus 2 > India (mimics P. hector ); 
P. borealis 2 , Ningpo; cyrus 2 ; /'. ceylanicus 2 / P. javanus; 
F. nicobarus 2 : P. astyanax. 
II. Island.— 2. Toothed $ , tailed 2 •—P- theseus $ , Malayana ; P. 
theseus 2 (toothed), Timor (mimics, P. aristolochiae var. diphilus) ; 
P. timorensis 2 » Borneo, Java, Timor (mimics P. polyphontes); 
P. theseus var. antiphus 2 (?), Sumatra, Lombock (mimics P. antiplius); 
P. melanides 2 , (Borneo) Banjarmassing, isolated form ; P.numa. 
3. Tailless $ , toothed 2 •—P. alphenor $ , P. alphenor 2 i Molucca, 
Celebes and Philippines, Bourn, Ceram ; P. ledebouria 2 , Philippines 
(mimics P. polydorus (?)); P. elyros 2 , isolated form. 
4. Tailless $ , tailless 2 .—P. nicanor $, Gilolo, Batchian ; P. 
nicanor 2 , very local. 
5. New Guinea group: P. anthrax, P. ambracia, P. epirus, P. dunali. 
Mr. Edwards proceeded to give the history of the discovery of 
these relationships. Ho said : “ The species was first described by 
Linn6, in the year 1758. His description was undoubtedly made 
from a female specimen, and was separated from what is now known 
to be the male form, but which Linne called P. pammon. Some time 
afterwards, Westerman bred both P. pammon and P. polytes from 
similar larvae, and he was the first to surmise that the two very.
