caudal. That the other three groupes of terrestrial Adephaga may be distinguished by their 
larve in like manner, I infer from a circumstance recorded by M. Latreille, who says, that the 
larva of Aristus has the form and manners of the larvae of Cicindelide, a circumstance perhaps 
only to be accounted for on those principles of natural distribution which I have explained at 
length, Hore Entomologice, Part ii. p. 518.

The Adephaga Terrestria of Clairville having attracted the attention of all the most cele- 
brated of modern Entomologists, and having been much more studied than any other groupe 
of insects whatever, it is singular that so little should have hitherto been done towards their 
natural arrangement. M. Latreille, even in the very first number of the work which he and Baron 
Dejean have commenced on the Coleopteres de ? Europe, abandons the hope of effecting a natural 
arrangement. When I therefore attempt to combat this difficulty in the above rough sketch, it 
is because it becomes necessary, in order that my readers may form an adequate notion of Dr. 
Horsfield’s acquisitions in this branch of natural history. The five families I have given above 
answer, with very little variation, to the 4bdominales, Cicindelete, Truncatipennes, Bipartiti and 
Thoracicit of Latreille: who, however, seems to be little more aware of their mutual connexion 
than he is of the groupe Chilopodomorpha. The above names, indeed, used by him, I do not 
adopt, because, in the first place, they disturb that harmony of nomenclature which is so 
essential to the interests of Entomology ; and, secondly, because they appear fanciful, and do not 
sufficiently express the characters of the respective fumilies. I have thus thought proper to 
name them from the most remarkable or best known genus in each. M. Latreille has another 
family called Swhulipalpes, composed solely of his old genus Bembidion, and of which the prin- 
cipal distinctive character is the subulate form of the last joint of the maxillary palpi, as if 
there were not insects in almost every adephagous family which possess this character. The 
family of Subulipalpes is therefore clearly to be abolished, and we shall find that the natural 
place of Bembidion is in one of the five families above laid down. 
On examining the five families in the above table, we find the stirps returning into itself 
and being thus a natural groupe; for it is easy to perceive that H/aphrus has a connexion both 
with the Cicindelide and Carabidae, that Panageus and Licinus lead us from these last to the 
Harpalide, that Acinopus and Cephalotes lead us from these by means of the genus dristus to 
the Scaritide, that Siagona conducts us from the Scaritide to the Brachinide, from which 
by means of Anthia and Manticora we return to the Cicindelide, ‘That parallel analogies exist 
in these families, cannot be doubted by any one who considers the genera Colliuris, Agra, 
Dischyvrius, Stomis and Cychrus, or Megacephala, Anthia, Scarites, Chlenius and Carabus, or 
Cicindela, Graphipterus, Siagona, Blethisa, and Nebria, &c. &c. The genus Enceladus seems _ 
also to connect the opposite points of the circle of affinity, by connecting the Carabide with the 
Scaritide.
