IgO STATES OF INSECTS. 



from the apterous to the winged tribes of Insects, it seems 

 most consistent with general analogy that each should 

 connect with the other in that state in which the resem- 

 blance is greatest. Now the Myriapoda resemble larva?, 

 as we have just seen, most when in their adult state; 

 therefore the comparison should be between larvae and 

 adult Myriapoda. 



Mr. MacLeay divides coleopterous larvse into five tribes 

 thus characterized : — 



1 . A carnivorous hexapod larva, with an elongate linear 

 Jlattened body, having a large head armed with two sharp 

 falciform mandibles, and furnished with six granular eyes 



on each side. This kind he denominates Chilopodiform, 

 as having for its type in the Ametabola, Scolopendra L. 

 The examples he gives are Carabus and Dytiscus. 



2. A herbivorous hexapod larva, with a long and al- 

 most cylindrical body, so fashioned that the posterior ex- 

 tremity being curved under the breast, the animal when at 

 rest necessarily lies like an Iulus on its side. This tribe 

 he denominates Chilognathiform, from Iulus L. His ex- 

 amples are, the larvae of Petalocerous insects, as Scara- 

 ba?us L., Lucanus L. &c. 



3. An apod larva, having scarcely the rudiments of an- 

 tenna, but which is furnished instead of feet with fat fleshy 

 tubercles; which, when continued along the bach and belly, 

 give the animal a facility of moving in whatever way it 

 may be placed. These he denominates Vermiform, from 

 certain of the Vermes intestina and Mollusca of Linne 

 which he has associated with life Annulosa a . His exam- 

 ples are, Curcidio L. and Cerambyx L. 



4. A hexapod and distinctly antenniferous larva, with a 



a The Intestinaiu cavitaires of Cuvier, and the E2?izoaria of La- 

 marck. See Hor. Entomolog, 286 — .
