160 STATES OF INSECTS. (Larva.) 
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- 
baeus L., Lucanus L. &e. 
3. An apod larva, having scarcely the rudiments of an- 
tenne, but which is furnished 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. ‘These he denominates Vermzform, from 
certain of the Vermes intestina and Mollusca of Linné 
which he has associated with his Annulosa*. His exam- 
ples are, Curculio L. and Cerambyzx L. 
4. A hexapod and distinctly antenniferous larva, with a 
subovate rather conical body, of which the second segment 
is longer and of a different form from the others, so as to 
give the appearance of a thorax. THis denomination for 
these is Anopluriform, from Pediculus L., forming Dr. 
Leach’s Anoplura. His examples are, Coccinella and 
Chrysomela L. 
5. A 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 ap- 
pendages to the last segment of the abdomen. ‘This tribe 
he calls Thysanuriform, from Lepisma and Podura 1.., 
forming M. Latreille’s order Thysanura. His example 
is Meloe with a note of interrogation °.

> Hor. Entomolog. 422. comp. 463. Mr. MacLeay’s idea of the 
larva of Meloe is taken from the animal which Frisch, Goedart, and 
De Geer imagined to be such ; but upon this opinion there rest great 
doubts. (See Kirby Mon. Ap. Angi. ii. 168, and Latreille N. Dict.
