or 
ANNULOSA JAVANICA. 
COLEOPTERA. 
An attempt has been made in the Hore Entomologice to shew that if we gradually limit our 
views, and descend from the consideration of the kingdom Animalia to the department or sub- 
kingdom Annulosa, from this again to the class Jfandibulata, and then to the order Coleoptera, 
thus leaving each groupe for one of its component minor groupes, we shall at length observe 
the last-mentioned, viz. the order Coleoptera, to resolve itself into five minor groupes, which I 
have termed tribes. Now one of these tribes consists of insects having Chilopodiform larye ; 
that is, their larvae are carnivorous, having their head furnished with ocelli and strong man- 
dibles, generally pierced for suction. Their body is subdepressed, composed of angular, or at 
least of laterally incontinuous segments, of which all, or at least a certain portion, are each 
covered with a corneous lamina. Some one of the hinder segments of the body (in general the 
penultimate or last) is moreover always furnished with at least two styliform appendages, which 
are sometimes corneous, sometimes membranaceous, and sometimes articulated. From this 
general resemblance of the larvze to young Chilopoda, the tribe may be termed 
CHILOPODOMORPHA. 
Character Typicus. 
Larva chilopodomorpha plerumque carnivora, corpore processubus duobus posticis styliformibus 
dorsalibus semper instructo. 
Imaco plerumque pentamera, mandibulis corneis, maxillis hipartitis vel processubus duobus ; 
lacinid interiori in unguem corneum incurcum fere semper desinente ; lacinid exteriore sepius biar- 
ticulatd interdum palpiformi. 
I have elsewhere shewn that nature appears to have varied less in the structure of the 
maxillz than in any other part of the mouth of Coleoptera, and have consequently inferred that 
the Entomologist ought to pay particular attention to the form of the maxille in the perfect 
insect. In the tribe having Chilopodiform larvee, we have a remarkable example of the truth of 
this reasoning, for a particular modification of that form of maxillae which is general to this tribe 
caused the carnivorous insects, or Adephaga of Clairville, to be early separated from all other 
Coleoptera by a most anomalous character, viz. that of having six palpi. When Savigny, how- 
ever, reduced to one general structure the mouth of all winged insects, it followed as an imme- 
diate consequence, that Coleoptera do not differ so much among themselves as that two or three 
families should have four maxillary palpi and all the rest only two. We find, accordingly, that 
a more philosophical view of the subject did not fail to be taken by M. Latreille, as soon as he 
had weighed with due consideration the theory of M. Savigny.* For instance, the maxille of 
Coleoptera may be described generally as being composed of several pieces which are often 
entirely confluent, and generally so far confluent as to form one mass; the interior palpi (as they 
are called) of adephagous insects forming almost the only known exception to the rule. But even
