422 ON THE TRIBES 



such types we have, First, a Carnivorous Hex.apod larva, 

 with an elongate, linear and flattened body, having a large 

 head armed with two sharp falciform mandibles, and fur- 

 nished with six granular eyes on each side. Example : Ca- 

 rabus or Di/tiscus. Secondly, A H erbivorous Hexapod lar- 

 va with a long and almost cyhndrical body, so fashioned that 

 the posterior extremity being curved under the breast, the 

 animal, when at rest, necessarily lies like an luhis on'its side. 

 Example : Petalocerous larvce. Thirdly, Apod larva, hav- 

 ing scarcely the rudiments of antennse, but which is fur- 

 nished instead of feet with fat fleshy tubercles, which, when 

 continued along the back and belly, give the animal a facility 

 of moving in whatever way it may be placed. Example : 

 Curculio or Ceramhyx. Fourthly, Hexapod and di- 

 stinctly Antenniferous larva, with a subovate rather coni- 

 cal body, of which the second segment is longer and of a 

 diflferent form from the others, so as to give the appear- 

 ance of a thorax. Example : Coccittella or Clirysomela. 

 Fifthly, Hexapod Antenniferous larva of an oblong form, 

 having like the former vestiges of a thorax, besides two or 

 more articulated or inarticulated setaceous or corneous 

 appendages to the last segment of the abdomen. Exam- 

 ple : Meloe?- 



Every Coleopterous larva which I have had the oppor- 

 tunity of observing may be assimilated to one or other of 

 these types, which it was scarcely possible to look at with- 

 out being reminded of the Ametahola. Indeed, it occurred 

 to me almost immediately, that I had Chilopodiform, Chi- 

 lognathiform, Apod or Vermiform, and Anopluriform 

 larvae, together with a fifth form, of which I even now 

 know little except from the examination of two or three 

 larvas collected by myself, together with the almost mar-
