INTRODUCTION
India has been appropriately described as the butterfly-collector's paradise. and
perhaps no other group of insects in India has been so exhaustively studied and
described as butterflies are. The.rich and fascinating variety in their form and size. and
the gorgeous splendour of their colour and patterns of colour markings have attracted
both the amateur naturalist and the professional scientist. and the popular interest
which this group has always aroused has, been in a large measure responsible for the
substantial mass of literature. both popular and scientific. on this large and attractive
assemblage of insects.
Talbot. in his volume on Butterflies. in the Fauna of British India series (second
edition. 1929). has outlined briefly. yet thoroughly. the history oft he previous work done
on butterflies in this country. in his Introductory chapter. He has listed therein almost
all the important publications on the butterflies of India and to this list may be added
the excellent monograph on the Butterflies of the Indian Region by Wynter-Blyth.
published by the Bombay Natural HistolY Society in 1957. One might wonder whether
in view of all this exhaustive literature. there is any real need for a descriptive catalogue
of the kind that has now been complied. Although it should be admitted that there is
very little scope for any original work on the systematic study of Indian Lepidoptera. yet
it was considered necessary to bring out a catalogue of all the species of butterflies so far
represented in the collection of the Madras Government Museum. in order to make the
collections of this Museum better known among the other Museums and scientific
institutions both in India and abroad. But at the same time it was felt that a well
illustrated and descriptive catalogue w1ll be much more useful than a mere handlist of
names. Again. almost all the earlier works including the volumes on butterflies in the
Fauna of British India series have dealt with butterflies of the entire Indian Region. and
as most. of the species described therein are found only in Assam. Sikkim. Bhutan and
other areas in the far north. the student Wishing to concentrate on the identification of
South Indian butterflies often feels considerable difficulty in wading through the entire
range of species before he is able to determine the South Indian species. As the Madras
Museum collection contains mostly South Indian species. it is expected that the present
work w1ll serve more or less as a guide to South Indian butterflies on which there is no
convenient handbook at present. It was mainly these considerations that prompted the
author to compile the nresent catalogue in the descriptive and illustrated form in which
it has appeared; and incidentally. when the measurements of the wing expanse of the

specimens In the collection were compared to the existing records for the corespondIng
species. it was found that In many cases the measurements were above or below the
maximum and pUnimum recorded. expanse for these partlcuJar specIes. thereby establishing
newtecords In the range of expanse for these species.
Regarding the structure. variation. distribution. ecology and methods of setting and
preserving butterflies. Talbot and Wynter-Blyth have given exhaustive accounts In their
respective publications cited above. and it is therefore needless to repeat them here.
The classification adopted in the present catalogue is that adopted by Wynter-Blyth.
This is the same as that followed by Talbot In his volume In the Fauna of British India
series (Volume I). for Papilionldae and Pieridae. as this is the most up-to-date standard
work on Indian butterflies. belonging to these families. For the remaInIng families. the
classification followed by Evans in his "Identification of Indian Butterflies" has been
followed.
In Identifying butterflies. It is necessary to remember that there is consIderable
seasonal and individual variation in many species of butterflies. Hence it is necessary
to confirm the identifications made with the help of deSCriptIons by checking the locality.
size. habit and other details before one can 'be sure of the identification.
In order to identiiY a butterfly correctly. one has to become conversant with the
structure oft he wings oft he butterfly and their venation. and with the various descriptive
terms applied to the different part of the wings.
The terminology of the various parts of the wing and its venation is illustrated in the
accompanying figure.
The majority of the specimens represented in the Museum collection are from
localities In South India although the general range ofd istribution 9fthe species to which
they belong may be much wider. extending into localities In North India. even as far as
the Himalayas. Assam. Sikkim. Bhutan. and sometimes even to Burma and Malay
Peninsula. In South India. it is the hilly regions. such as the Nilgiris. PuIney Hills.
Western Ghats. etc. . that are particularly rich In butterflies. especially those of the
larger. more colourful and attractive species. but a large number of species occur also in
the plains.
The total number of species of butterflies recorded from the Indian Region is about
868 and out of these. the distribution of about 285 species extends to South India. The
number of species of butterflies found exclusively in South India is about 45. most of
which are found in the hilly regiOns such as the Nilgiris. Pulney Hills and Western Ghats.
The number of species represented in the collection of the Madras Government Museum
is 228. almost all of them being South Indian forms. but their distribution extends in
most cases to North India and sometimes even beyond Indian limits. In a large number
of cases it is the South Indian races of the species that are represented in the Museum
collection.

is the average oft he largest and the smallest oft he specimens. w1;lere there are more than
two specimens. In the case of species ofw hich only two specimens are represented. it is
the average of these two. ~d in cases where there Is only a single specimen. the
measurement of this single specimen is mentioned. Special mention is made 011
specimens which measure either less or more than the minimum or maximum recorded
expanse respectively. for the particular species.
The literature on this subject Is very extensive. and apart from standard descriptive
works such as Lepidoptera Indica and the Fauna of British India volumes on Butterflies.
numerous papers have been published on Indian butterflies. notably in the Journal of
the Bombay Natural History S~iety. Records of the Indian Museum. Journal of the
Aslatc Society of Bengal and the Proceedings of the Zoological Society of London. An
abridged bibliography on the subJect. listing some of the standard monographic works
and a selection of the more important systematic papers. is appended at the end of the
present paper. but further references can be readily traced by the reader from the
extensive bibliography in the latest edition of the volume on Butterflies by Talbot in the
Fauna of British India series.
I wish to acknowledge my gratitude to Miss. D. Chandramirtham. former Assistant
Curator for Zoology. for her assistance in rearranging the collections. preparing the
systematic lists oft he species and taking the wing measurements oft he specimens in the
collection. to Miss. A. Vimala. former Assistant Curator for Zoology. for her assistance in
the preparation of the Bibliography and Index. and to Sri R.N. Meganathan. Artist
modeller of the Government Museum. Madras. for the care and skill with which he has
prepared the coloured illustrations for this paper.
