Systema Nature was published only 2,724 species. These he 
divided into seven Orders: Coleoptera, Hemiptera, Lepidoptera, 
Neuroptera, Hymenoptera, Diptera and Aptera. His Order 
Hemiptera embraced the Orthoptera as well as the Rhynchota, 
otherwise the Orders remain now as they were then. These 
Orders he divided into 77 genera, the names of all of which 
are in use except, perhaps, Phalena. Some of the larger 
genera he broke up into sections or phalanges, ‘‘To facilitate re- 
ference,” as he says. These sections he indicated by asterisks 
accompanied by a few words of description, such as ‘Corpore 
ovato” or “ Corpore cylindrico.” Hach of the descriptions of 
species which follow begins with “ovatus” or “ cylindricus” 
as the case may be. When suitable Greek or Latin names of 
insects such as Bombyx, Locusta and others were available, 
he used these as the first word of his sectional diagnosis, 
‘‘ Bombyces elingues Alis reversis,” ‘‘ Noctu elingues,” etc., 
then each description which follows begins with “ Noctua 
elinguis.” 
In the five divisions of Gryllus alone are these words or 
popular names used in the singular, with full stops after them, 
followed by a short diagnosis. They are Acrida, Bulla, Acheta, 
Tettigonia and Locusta. Cicada is divided into five groups : 
Foliace, Cruciate, Manniferz, Ranatre and Deflexe ; Cimex 
is divided into nine groups: Apteri, Scutellati, Coleoptrati, 
Spinosi, Rotundati, Seticornes, Oblongi, Spinipedes and 
Lineares. Papilio is divided into five groups : Equites, Heli- 
conii, Danai, Nymphales and Plebeji ; Phalena is divided into 
eight groups: Attaci, Bombyces, Noctuw, Geometre, Tortrices, 
Pyralides, Tine and Alucite. 
Those which have a generic sound about them, such as 
Bombycz, Noctuz, Heliconii, are given in his list of ‘‘Termini 
artis’? with antenna, larva, pupa, etc. This list, however, 
includes the names of Orders, Coleoptera, Hymenoptera, etc. 
Most of these terms have been taken up, in the singular 
number, by subsequent writers as genera. 
It should be noted that the genus Tetéigonia of Fabricius 
has no reference to the term Tettigonia of Linnzeus ; nor has 
the genus Ranatra of Fabricius any connection with Ranatre, 
one of the Linnean divisions of Cicada.
