CLASSIFICATION OF DIPTERA. n 



3. Roeselii — lepidoptera. 



4. Reanmurii — proboscidea. 



5. Frischii — coleoptera. 



He Started by changing the Linnsan names Hemiptera, Hymen- 

 optera, Diptera to Proboscidea, Aculeata, and Halterata respectively. 

 His first order (Lucifuga) included the Crustacea ; the second the 

 Halterata, Aculeata, and Caudata ; the third the genus Sphinx, 

 Phalffina, and Papilio. The two last divisions were respectively 

 divided into terrestrial and aquatic. 



Another author who greatly improved this study was Schacffer, 

 who in his publications between 1764 and 1777 gave to the world 

 some valuable instruction in the mode of insect-collecting and in 

 the description of the microscopes used. He also described a large 

 number of species to illustrate his system of classification, which 

 differed considerably from the Linnffian method, and which became 

 of some repute. He formed seven orders, the characters of which 

 it is not possible to give here. The following are the seven orders : 



Insecta coleoptero-macroptera. 

 coleoptero-microptera. 

 coleoptero-hymenoptera = hemiptera. 

 hymeno-lepidoptera. 

 hymeno-gymnoptera. 

 diptera. 

 aptera. 



About the latter end of the eighteenth century a good many lists 

 of species had been published, both in England and abroad, and the 

 science of entomology made great strides, but as yet no specialists 

 of any repute had come forward. Entomologists were, in fact, only 

 finding out some systematic base to work upon. As we have already 

 seen, a large number of varied modes of arrangements had been 

 formed, only one of which, the Linnsean, being taken into any 

 account at the present day. A man destined to overthrow the 

 Linnjean system for a short time, and whose classification is still 

 considered of great value, appeared at this period, namely, Fabricius, 

 who in 1775 brought forward his novel classification in his work 

 entitled " Systema Entomologica." The mode of classification that 

 he adopted was by the characters of the mouth parts. He continued 

 to publish a large number of systematic works, each one containing 

 a modified arrangement of the preceding, and in his last work the 

 insects were divided into the following thirteen orders : i. Eleu- 

 therata ; 2. Ulonata ; 3. Synistata ; 4. Piezata ; 5. Odonafa ; 6. 

 Mitosata ; 7. Unogatce ; 2>. Polygnata ; c). Kleistagnata ; 10. Exoch- 

 nata ; 11. Glossata ; 12. Rhyngota ; 13. Atitliata,
