The succession of genera is as follows, adopting modern generic names: 

 Todis lactearia; then follows Drepana falcataria, a Bombycid moth; TJrapteryx 

 sambucaria; Pn ,><//></ lacertinaria,. also a Bombycid; Evgonia alniaria, and 

 allied forms ending with the European Geometra papilionaria. The Seti- 

 cornes begin with Nemoria viridata and end with Cheimatobia brumata. This 

 division includes some Pyralids, and it will he seen thai the arrangement is 

 essentially an artificial one, except that on the whole the disposition of spe- 

 cies agrees with presenl classifications; those comprised in the Vrapt&ryna 

 and Ennominee standing above the Geomelrince. 



In 1793, Fabricius, in the " Entomologica Systematica," simply followed 

 Linnaeus in dividing the genus Phalcvita into two sections: 1. Antetinis pecti- 

 natis; 2. Antennis setaceis. His first division begins with Iodis latearia, and 

 the second division includes besides the Phalsenids with simple antennae, the 

 Platyptericince, and the Deltoid moths. It will he seen that he simply fol- 

 lows the arrangement of Linnaeus. 



In 1801, Denis and Sehiffermiiller, in their celebrated work " Syste- 

 malisches Verzeichniss von dot Schmetterlingen der Wiener Gegend" made 

 the following arrangement of the Pkalcenidce, based on the larval characters. 



The group termed Geometra, Linn. {Phalcena, Fabr.), is divided into 

 the following subdivisions : 



I. Larvce pedibus duodecim, subdivision A beginning with Metrocampa 

 tnargaritaria. 



II. Larvce, pedibus decern, subdivisions A to P, group A beginning with 

 Geometra papilionaria and ending with Acidalia ornata, group P beginning 

 with Petrophora dot (tin. 



Much fault may be found with this arrangement, but it is the first 

 attempt to give a natural arrangement founded on the larval stages. The 

 divisions I and 11 are unnatural ones, as in the genus Anisopteryx we have 

 one species {A. pometaria) hitherto regarded as being scarcely more than a 

 variety, which has rudiments of a third pair of abdominal feet, and the other 

 (A. vernata) entirely without such rudimentary appendages. The same 

 group P. besides several species of Pelrophora and Acidalia, respectively, con- 

 tains Pellonia vilncaria. 



In 1807, Latreiile (Genera Crustaceorum et Insectorum, iv), under the
