164 STATES OF INSECTS. (Larva.) 
elongate, terminating in three or more mucros. Ex. 
Larva from Brazil. Perfect insect at present un- 
known. ; 
I have placed this larva, which was described above*, 
amongst crustaceous forms, because of the remarkable 
resemblance which the last segment of the body bears to 
that of the Zdoteide ; but I do it with considerable hesi- 
tation, since in other respects its type seems to be in the 
Ametabola. In its want of antenne, very short legs, and 
ventral asperities, it resembles some of the Vermzform 
larvee; in its small head, distinct thoracic shield, and ob- 
long shape, it approaches the Anopluriform ; and in its 
very depressed body, but not at all in other respects, 
the Chilopodiform. At any rate, it appears of a primary 
Type. 
10. Lemodipodiform. Herbivorous ; hexapod ; antenni- 
ferous, with long antennze: body elongate, subcylin- 
drical ; second segment of the trunk the longest ; 
anterior pair of legs distant from the other two. Ex. 
Phasma. | 
11. Amphipodiform. Herbiverous; hexapod; antenni- 
ferous, with long antenne: body shortish, com- 
pressed, saltatorious. Ex. Gryllus L. 
12. Stomapodiform. Carnivorous or saprophagous; hex- 
apod; antenniferous, with long antennz : body elon- 
gate, subdepressed, with raptorious hands, and ab- 
domen wider than the trunk; in aquatic species fur- 
nished with lateral gills. Ex. Mantis, Ephemera ? 
Sialis ? 
13. Decapodiform. Carnivorous; hexapod; antenniferous:
