STATES OF INSECTS. 167 



will probably carry with it the whole tribe of vesicatory 

 beetles. But even this animal in its general structure is 

 anopluriform ; the only circumstance that gives it any ana- 

 logy to the Thysanura being its anal setae. Mr. William 

 MacLeay is inclined to regard some of the larvae of the 

 Malacodermi Latr., but which of them he does not state, 

 as probably belonging to the tribe in question a . Those of 

 Lampyris and of Telephones, as described and figured by 

 De Geer b , appear to me intermediate between the Ano- 

 pluriform and Chilopodiform Types : they have no anal 

 setiform or styliform appendages, their mandibular are 

 falcate, and their habits seem carnivorous. 



Examples of Chilopodiform coleopterous larvae are 

 more numerous. Of this description are those of Gy- 

 rimis, Cicindela, Carabus, and Staphylinus. That of the 

 first, indeed, appears to be the most perfectly Scolopen- 

 driform of any yet known; yet the gills or respiratory 

 laminae, a pair of which issues from each abdominal seg- 

 ment, and two pair from the last c , prove that there is 

 no slight analogy between it, and indeed many other 

 aquatic larvae, and the Stomapoda amongst the Crustacea. 

 A remarkable instance of analogy with the Decapoda of 

 the same Class is presented by the larva of JDytisctis, &c. 

 which Mr. MacLeay considers as Chilopodiform^ but 

 which exhibits no other resemblance to Scolopendrce than

c Ibid. t. xm.f. 16 — 19. A very singular larva, -which preys upon 

 that of Aleyrodes proletella Latr., if Reaumur's figure be correct (ii. 

 t. xxv. f. 18 — 20), is of a perfect Chilopodiform type, the abdomi- 

 nal legs being represented by a tubercle crowned by a bristle: yet 

 even this, which turns to a minute beetle (Ibid./. 21), has some ten- 

 dency to the Anopluriform type.
