found they would properly belong to his genus Pericheta, which, 
however, upon more mature examination, I believe, as I have stated 
above, to be synonymous with the genus Megascolex of Templeton. 
The species hitherto described are all natives of Ceylon; but in the 
National Collection we have a specimen from the Dukhun (Deccan), 
in India, and two or three from New Zealand, undescribed ; and I 
wrote to Mr. Johnstone to ask if there was anything in the dung-bed 
which came from that island or from India, through which the 
Worms could have been introduced into this country. In answer he 
tells me that ‘‘ he does not know of any matter, in the bed, from the 
East Indies.’ There are, he adds, a few Orchids amongst the plants ; 
and the bed has been partially emptied annually for five years, the 
same kind of worms being always found there. Mixed with these 
worms, in the same bed, are numbers of a common British species, 
some of which Mr. Johnstone kindly sent me, and which upon exa- 
mination I found to be the Lumbricus fetidus of Duges. 
Perhaps upon attention being called to these Earth-worms of Indian 
form, they may be found in other parts of the country in similar 
situations. 
4. Description of a new Genus of Heterocerous Lepidoptera, 
founded upon the Papilio charmione of Fabricius. By 
Arruur G. Butter, F.L.S., F.Z.8S., &e. 
At page 205 of his ‘ Entomologia Systematica’ Fabricius describes 
a very remarkable species of Lepidopterous insect under the name 
of Papilio (Danais) charmione, the characters of the species being 
probably taken from a figure by Mr. Jones, whose ‘ Icones’ furnished 
Fabricius with many of his new species. This figure was copied by 
Donovan in 1827, forming the subject of the 171st plate of his 
‘Naturalist’s Repository,’ vol. v. 
Fabricius gives the Island of Johanna as the locality from which 
charmione was obtained. But Donovan remarks, ‘‘ We, however, 
perceive in our copy of the ‘Entomologia Systematica’ that this 
habitat is erased, a correction made by ourselves many years ago 
upon the authority of Mr. Jones himself.” 
In his ‘Species Général des Lépidoptéres’ (published 1836) M. 
Boisduval referred this species to the genus Terias (Pierine), with 
the following observation :—‘‘ Ne l’ayant jamais vue, nous n’affirmons 
pas qu'elle appartienne au genre Terias.”’ But in the margin of the 
page I find a note in pencil by Mr. E. Doubleday—“ Not even a 
Butterfly.” 
The supposition that charmione was a Rhopalocerous insect seems 
to have arisen from the fact that it is represented as such by Dono- 
van. Whether the antenne really are clubbed or not, is a question 
that can only be decided when we see a perfect example of the spe- 
cies ; at present the only point that can be settled is that the species 
certainly is not a Butterfly ; for an old and well-worn specimen in
