It will be seen tliat the arrangement, based on tbe larval stages, is an 

 artificial one, and op(;n to the same objection as,tbat of Denis and Schiffer- 

 miiller. It begins with the Ennoniincn (in part) ; Geometra is placed above 

 Hibcrnia &nA Boar/nia ; Acidalia and Aspilales arc l)rought together; and Ura- 

 pteryx succeeds all these, while Gnoplios is widely separated from Boarmia. 

 The Laientince come last and lowest, with the exception of Tanagra (Bapta), 

 Siona, and Minoa and Cidaria, which shonld really precede the genns La- 

 rentia {Glaucopteryx, Fetrophora). Duponchel includes the Noctuid genus 

 Ligia in the family, placing it between Fidonia and Numeria. 



In the same year, Stephens published "The Nomenclature of British 

 Insects'', a simple list with many new genera. He proposes the terni Geo- 

 metridce for th(^ family, but does not attempt a subdivision of it. 



The succession of genera is l^ere given. A few new genera are indi- 

 cated (n. g.), but not named. Fsychophora, Speranza, Fidonia, Bupalus, 

 Anisopteryx, Lampetia, Ampliidasis, Biston, Metra, Crocallis, n. g. (Eiinoinos 

 bide/I tata), Geometra, FericaUia, n. g. (Hijiparchus Frunaria), n. g. (Euno- 

 mos cratcegata), Ourapteryx, Phalcena, Ellopia, Hipparchus, Chora, Aids, 

 Hemerophila, Boarmia, Grammatophora, Azinephora, Cabera, Cyclophora, 

 Bradyepetes, Aspilates, Larentia, Cidaria, Harpalyce, Steganolophia, Electra, 

 Idtta, Abraxas, n. g. {Xerene melanariu), Xerene, Ypsipetes, Fhibalaj)teryx, 

 Scotosia Triphosu, n. g. {Acidalia bilineata), n. g. {Acidalia undulata), Cha- 

 rissa, Fachycnemia, Lozogrumma, Ai^ocera, Chesias, n. g. (Cbesias simulata), 

 n. g. Acidalia diluiata, Cheimatohia, Lobophora, Eupithecia, Minoa, Baptria, 

 Emmeksia, Hercyna, Hyria, Ftychopoda, Alacaria, Ennomos. 



The arrangement is very objectionable, beginning with Fsychophora, 

 Speranza and Fidonia, and ending with Macaria and Ennomos; Cidaria, Har- 

 palyce, Electra, and Eupithecia preceding Macaria. The merit of the; work is 

 in the propo.sal of desirable new genera, though in this he and Duponchel, as 

 well as Curtis and Treitschke, have ignored Hiibner. Whether Stephens's 

 work appeared Ixifore Duponchel's fourth volume or not is not know^n. Du- 

 ponchel's names should, of course, have priority, since the descriptions and
