Tlie succession of genera is as follows, a(k)i)tini? iiiodern generic names: 

 lodis Idclcaria; then follows Drejmna falcutaria,ii Bombjcid moth; lhrq)tciyx 

 aambucaria ; Drcpana laccrtinaria, also a Bombycid; Evgonia (dnidria, and 

 allied ibrms ending with the Pjuropean Geometra pajyiUonaria. The Seti- 

 rornes begin with A'enio/ia virixhitd and end with Cheimalohia hrvmala. Tliis 

 division inclndes some Pyralids, and it will l)e seen that the arrangement is 

 essentially an artificial one, c.\ce|)t that on the whole the disposition of spe- 

 cies agrees with present classitications ; those comprised in the Zlrapteryno: 

 and EnnomincB standing ai)ove the Geomclrinoi. 



In 17i)3, Fabricius, in the " Entomologica Systematica,'^ simply followed 

 Linnteus in dividing the genus Phalcena into two sections: 1. Antcnnis pccti- 

 nafis: 2. Antt-iinis aetaceis. His first division begins with lodis latearia, and 

 the second division includes besides the Phalae>nids with simple antennte, the 

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

 lows the arrangement of Linna?ns. 



In 1801, Denis and Schiifermiiller, in their celebrated work '' Sysle- 

 malisches Verzeichniss von den Schmett'erUngen der Wiener Gegcnd^'' made 

 the following arrangement of the Phalmiulce, based on the lai-val characters. 



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

 the following subdivisions : 



I. Larva: pedibm duodcciiii, subdivision A beginning willi Metrocampa 

 marguritarki. 



II. Lanm jmlibus decern, subdivisions A to P, group A beginning with 

 Geomclra jiapilwnaria and ending w ith Acidalia ornata, group P beginning 

 witli Pc/ropliora dotata. 



Much iault may be found with this arrangement, but it is fhe first 

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

 divisions I and II ar(' unnatural ones, as in the genus Anuoptrrijx we have 

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

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

 {A. vernatu) entirely without such ludimeiitary appendages. The same 

 group P, besides several species of iV>-op//ojv/ and JcvV/r/Z/r/, re.'<j)ectiv{'!y, con-
