ANNULOSA JAVANICA. 
INTRODUCTION. 
As this Work is to be conducted with as much reference as possible to those general prin- 
ciples of natural distribution which I have laid before the Public, both in the Hore Entomologice 
and the Transactions of the Linnean Society, the reader may easily perceive that there will be 
some novelty in the arrangement, as well as in the matter arranged. In abandoning, however, 
that division of Coleoptera which is founded on the number of joints in the tarsi, and which has 
acquired so much vogue on the Continent, it may be necessary to shew that I am countenanced 
by some authority. I shall, for this purpose, therefore, content myself with citing the following 
words of M, Latreille: that is, of the distinguished naturalist to whom the Tarsal System owes 
much more of its celebrity than to its inventor. “* Articulorum tarsorum progressio numerica 
decrescens in methodo naturali non admittenda.’’—(Gen. Crust. et Ins. vol. i. p. 172.) 
It will also be seen that I commence with the Adephagous Coleoptera, not indeed because they 
form a particularly rich part of the Hon. East-India Company’s collection, and still less from any 
notion of the Linnean genus Cicindela having a peculiar title to this pre-eminence, but because 
they constitute that department of the science which at present most engages the attention of 
Continental Entomologists. In the course of this investigation I shall have several new genera, 
or rather subgenera, to propose, of which the characters in some cases must necessarily rest on 
refined, and even minute considerations. Now, as the object I have in view is to make known 
in a definite manner ali the species that may be new, I cannot hope to carry this my intention 
into execution without adopting some of those delicate distinctions, which result from the mode 
of investigation that has lately been pursued by M. Bonelli, in his study of these insects. I 
have, indeed, little choice to make : for I must either expose myself to a charge very frequently 
at present brought against Entomologists—namely, that they disgust persons with the science 
by the multitude of names with which they load it ; or I must display unpardonable ignorance of 
the many excellent observations which could never have been discovered, nor can now be 
explained, without such a mode of discrimination being resorted to. When, therefore, I venture 
to add to the already overwhelming number of subgenera into which the Linnean genus Carabus 
has been divided, I have to state in excuse, that this course of proceeding is adopted from the 
conviction that it is impossible to assign some of the new Javanese forms to any of those genera, 
which MM. Dejean and Bonelli have almost entirely founded on the examination of European 
B insects.
