caudal. That the other three groupes of terrestrial Adephaga may be distinguished by their 

 larv«e in like manner, I infer from a circumstance recorded by M. Latreille, who says, that the 

 larva of Arutus has the form and manners of the larvae of Cicindelidce, a circumstance perhaps 

 only to be accounted for on those principles of natural distribution which I have explained at 

 length, Hora Entomologicse, Part ii. p. 518.

The Adephaga Terrestria of Ciairville 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 ColeopVeres de V 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 Abdomiriales, Cicindeleta, Truncatipennes, Bipartiti and 

 Tlwracici 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 families. I have thus thought proper to 

 name them from the most remarkable or best known genus in each. M. Latreille has another 

 family called /Subulipalpes, 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 Elaphrus has a connexion both 

 with the Cicindelida: and Carabidce, that Panagceus and Lieinus lead us from these last to the 

 Harpalidce, that Acinopus and Cephalotes lead us from these by means of the genus Aristus to 

 the Scarilidce, that Siagona conducts us from the Scarilidce to the Brachinidce, from which 

 by means of Anlhia and Manticora we return to the Cicindelida. That parallel analogies exist 

 in these families, cannot be doubted by any one who considers the genera Colliuris, Agra 

 Discht/rius, Stomis and Ci/chrus, or Megacephala, Anlhia, Semites, Chlanius 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 Carabidce with the 

 Scaritidce.
