24 Mr. F. P. Pascoe on the Genus Dicranocephalus. 
These remarks are rendered necessary, because, in the following 
proposed additions to the genus Dicranocephalus*, I do not put 
forward the three forms described as “ undoubted species,””—although 
it would not be difficult to cite many instances where, in other cases, 
this has been done on slighter grounds ; nor are they, in the present 
state of our knowledge, te be considered as merely geographical sub- 
species, and still less as instances of dimorphism. It is possible, and 
indeed not unlikely, that intermediate forms may hereafter be received. 
There is but a moderate gap to be bridged over; but, until that is done, 
I am sure that it would be contrary to all ordinary notions of specific 
distinction to unite them under the same name. 
The first of these forms, Dicranocephalus Wallichii, was brought 
from Nepaul by General Hardwicke more than thirty years ago, and 
was described? by the late Rev. F. W. Hope in Gray’s ‘ Zoological 
Miscellany,’ afterwards figuredt by Gory and Percheron in their 
work on the ‘ Cetonides,” and later by Prof. Westwood in his 
‘Arcana.’ I believe there were only two representatives of the 
genus in Europe until Mr. Fortune went to China, when he sent 
home altogether a large number of specimens, which were, and have 
continued to be, referred to D. Wallichiti. Mr. Bowring, however, 
as I understand, protested from the first at considering it identical 
with the old species. It is not merely as a compliment, therefore, 
that I have named it after him. 
Within the last week or two I have been presented with a fine set 
of Coleoptera collected in Japan, the coast of Mantchouria, south of 
the Amoor, &c., by Arthur Adams, Esq., late Surgeon of H.M.S. 
‘ Actseon ;’ and among others there was a specimen of the genus from 
Chosan, in the Corean Peninsula, which, on comparison, I found to 
* Often erroneously spelt Dicronocephalus. 
+ Shortly described, but without a word of a generic kind. Déicranocephalus 
remained a mere cata!ogue name until the publication of the third volume of the 
‘ Genera des Coléoptéres ;’ M. Lacordaire must therefore be cited as its autho- 
rity. MM. Gory and Percheron, in their hybrid jargon, called it ‘“ Goliath 
Wellech.” Dicranocephalus itself is an abominably unwieldy name, and had 
been previously used by Hahn for a genus of Hemiptera, but it does not appear 
to have been adopted. 
t The figure is very characteristic, and correctly drawn and coloured. That 
in the ‘Arcana,’ from its position, is less satisfactory, and is coloured a pale 
green. Mr. Hope’s phrase is “ pallide flavo-viridis.’” I should have thought 
that the British Museum specimen, from which Professor Westwood took his 
drawing, might originally have been green, but that the words of the French 
authors, “ gris-jawndtre,” are as applicable at this moment as they probably were 
originally.
