ZOOLOGY. Gil 



classes, namely, the Protozoa, Conchozoa, Worms and 

 Crustacea, a fact which is, properly speaking, self-evident, 

 and which is rendered clear by the following table. We 

 have thus : 



Order I. Tracheopteroid Coleoptera PhytopJiaga. 

 Order II. Dictyopteroid Zoophaga. 



Order III. Ceratopteroid Rypophaga. 



It can also be said ; the first correspond to the Worms, 

 the second to the Crustacea, the third to the Flies. 



Lastly, it may still be said ; the first correspond to the 

 Protozoa, the second to the Conchozoa, the third to the 

 Ancyliozoa. 



Order 7. Tracheopteroid Beetles PliytopJiaga. 



3527. Body cylindrical, head mostly long, antennae 

 setiform, maxillary teeth obtuse, tarsi mostly tetrameral. 



They gnaw hard seeds, leaves, and wood, and mostly 

 live concealed. The larvae almost or entirely apodal. 



Fam. 1. Dipter old Beetles Rhyneophora. 



Head rhynchiform or snout-shaped, tarsi tetrameral. 



Fam. 2. Hymenopter old Beetles, Blattk'dfer. 



Head tolerably short as well as the antennae, tarsi 

 tetrameral. 



Fam. 3. Lepidopteroid Beetles, Holzkafer. 



Head pretty short, antennae very long, tarsi tetra- and 

 pentameral Borkenkafer, Holzbohrer and Schroter. 



Order 8. Dictyopteroid Beetles Zoophaga. 



3528. Body long and depressed, antennae short, 

 maxillae large with pointed teeth, feet mostly pentameral 

 and without ungues. 



They subsist upon living or dead animals, dwell usually 

 in water or upon dry land, and run very swiftly. The 

 one kind seize upon living beasts, and on that account 

 constantly swarm about them, as the Raub- and Lauf- 

 kafer ; the others only subsist as larvae by suction upon 

 other beetles or snails externally, but live, as Flies, upon 

 leaves and flowers, as the Lampyridae and Cantharidae.
