40 MODERN CLASSIFICATION OF INSECTS. 



except from the examination of two or three collected by myself, 

 together with the marvellous descriptions of Goedart and De Geer." 

 {Horm Entomol. vol. ii. p. 4-22.) Subsequently the same author 

 states, that " the types of Chilopodiform larvae are those carnivorous 

 insects with four maxillary palpi, forming two groups, Carabus and 

 Cicindela Linn., and Ilydrocanthari Latr. To the same tribe, Hydro- 

 philus Geoffr. ought to be ascribed, from which, by Spha^ridium, we 

 enter among the Chilognathiform larvae, the type of which is ap- 

 parently Scaraba^us Linn. The tendency of Chilognathiform larvae 

 is herbivorous, having among them Lucanus, Byrrhus, Ptinus, Hister, 

 Elater, Buprestis, and part of Tenebi'io and Dermestes. By means 

 of Bostrichus Geoffr. we probably quit the Chilognathiform for the 

 Apod or Vermiform larvae, including Bruchus, Curculio, Attelabus, 

 Cerambyx, Leptura, Necydalis, and part of Tenebrio and Dermestes. 

 With the help of Donacia (nearly allied to Leptura), we quit this 

 tribe for the Anopluriform larvae, including Chrysomela, Cryptoce- 

 phalus, Coccinella, Cassida, and Hispa. These last lead to the 

 Thysanuriform larvae, including Meloe and Mordella, with many 

 Heteromera Latr., and perhaps Clerus. I suspect that some of the 

 Malacoderma Latr., find a place in this group, but certainly Staphy- 

 linus Linn., reconducts us from these insects to the Chilopodiform 

 tribe of larvae. Some groups I dare scarcely venture on, such as 

 Melasomes, Taxicornes, and Stenelytres Latr." We are then informed 

 of the important fact, that Pentamerous insects chiefly belong to Chi- 

 lopodiform or Chilognathiform larvae ; that Apod larvae become 

 Tetramerous ; Anopluriform larvae either Tetramerous or Trimerous ; 

 and Thysanuriform larvae either Heteromerous or Pentamerous. * In 

 the Annulosa Javanica, Mr. MacLeay declared his views relative to 

 the Chilopodiform type or tribe as follows : — 



Normal (jrovp, consisting of 

 insects having linear or 

 setaceous antenna, with 

 the outer process of the 

 maxillre palpiform.
