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. His denomination for 

 these is Anopluriform, from Pediculus L., forming Dr. 

 Leach's AnoplUra. His examples are, Coccinella and 

 Chrijsomela L. 



5. A hexapod antenniferous larva of an oblong form, 

 having like the former vestiges of a thorax, besides t*wo or 

 more articulated or inarticidatcd setaceous or corneous ap- 

 pendages to the last segment of the abdomen. This tribe 

 he calls Thysanuriform, from Lepisma and Podura L., 

 forming M. Latreille's order Thysanura. His example 

 is Meloe with a note of interrogation a . 



The system here stated, of naming and characterizing 

 larvae from the resemblance and analogy, in many cases 

 very striking, that they bear to the apterous tribes, is a 

 very happy and original one, and does its author great 

 credit; yet I think in some instances, as I shall soon 

 have occasion to point out to you, the application of it is 

 not so happy as the first idea. But this is always the 

 case when a new law of nature is discovered ; the proper 

 application of it is gradually developed, and it does not 

 at all detract from the merit of the first discoverer, that 

 all the bearings of such law do not strike him as it were 

 intuitively. 



a Hoi: 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. Aj>. Angl. ii. 168, and Latreille N. Diet. 

 (FHist. Nat. xx. 109.) At p. 464 he gives also Mordella and many 

 Heteromera as having Thysanuriform larvae. He thinks, that proba- 

 bly that of Clerus is of the same description ; to which he suspects 

 that many of Latreille's Malacoderma likewise belong.
