THE LARVA. 39 



2. With a corneous head of determinate shape, (many Coleo- 

 ptera, the Rhynchopkora, many Hymenoplera, Culicina, 

 Tipularid), PI. II. f. 3. 

 II . Larvae with feet. 



1. With legs only, and with or without an anal proleg. 



a. Joints short and conical (Elaterodea, Cerambycina), 



PI. II. f. 4. 



b. Joints longer (Cicindelacea, Carabodea, Hydrocan- 



tharides, Brachyptera, Lamellicornia , Cuccinellacea, 

 Neuroptera), PL II. f. 6. 



2. Prolegs only (Tipttlaria, and other Diptera, (Ecophora), 



PI. II. f. 2. 



3. Both legs and prolegs (Lepidoptera, Tenthredonodea). 



a. Without claws (Tenthredonodea'), PI. II. f. 5 and '/ 



b. With claws (Lepidoptera}, PI. II. f. 9 and 11*. 

 Prolegs, in some instances, occur upon all the segments of the 



abdomen, and even upon the thoracic segments there are found legs 

 resembling the prolegs in form, in those cases where true thoracic legs 

 are wanting (Rhynchophora). But in the majority of cases, the first 

 abdominal segment, or fourth segment of the body, has no prolegs, 

 but they are sometimes observable upon this segment ((Ecophora 



* Burmeister, in this table, does not exactly follow that given in the Introduction to 

 Entomology, vol. iii. p. 144. But why, after quoting it as that of Kirby and Spence, he 

 should make alterations in it, it is difficult to say, particularly as these alterations are not 

 material. But he refers to the German translation of their work ; and, from not knowing 

 that book, I am unable to determine how far it was the cause of the difference : but, to do 

 justice to these authors, I give the table in their own words : 



I. Larvae without legs. 



i. With a corneous head of determinate shape (coleopterous and hymenopterous 

 Apods Culicidce, some Tipnlarics, &c. amongst the Diptera). 



ii. With a membranaceous head of indeterminate shape (Muscidce, Syrphida, 

 and other Diptera). 



II. Larvae with legs. 



i. With legs only, and with or without an anal proleg (Neuroptera, and many 



Coleoptera). 



\. Joints short and conical (Elater, Cerambycidce, Sic.). 

 2. Joints long and subfiliform (Staphylinus, Coccinella, Cicindela, &c.). 

 ii. Prolegs only (many Tipularite, and some subcutaneous lepidopterous larvae, 



&c.). 

 iii. Both legs and prolegs (Lepidoptera, Serrifera, and some Coleoptera). 



1. Without claws (Serrifera, &c.). 



2. With claws (Lepidoptera, &c.). TR.
