It will be seen that the arrangement, based on the larval stages, is afi 

 artificial one, and open to the same objection as that of Denis and Schiffer- 

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

 Hibemia and Boarmia; Acidalia and Aspilates are brought together; and Ura- 

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

 The Larentince come last and lowest, with the exception of Tanagra {Bapta), 

 Siona, and Minoa and Cidaria, which should really precede the genus La- 

 rentia {Glaucopteryx, Petrqpkora). 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 term Geo- 

 metridce for the family, but does not attempt a subdivision of it. 



The succession of genera is here given. A few new genera are indi- 

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

 Anisopteryx, Lampetia, Amphidasis, Biston, Metra, Crocallis, n. g. {Ennomos 

 bidentata), Geometra, Pericallia, n. g. {Hipparckus Prunarid}, n. g. {Enno- 

 mos: cratcegata), Ourapteryx, Phalcena, Ellopia, Hipparckus, Chora, Alois, 

 Hemcrophila, Boarmia, Grammatophora, Azinephora, Cabera, Cyclopkora,- 

 Bradyepetes, Aspilates, Larentia, Cie/aria, Harpalyce, Steganolophia, Electra, 

 Idcea, Abraxas, n. g. {Xerene melanaria), Xerene, Ypsipetes, Phibalapteryx, 

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

 rissa, Packycnemia, Lozogramma, Aplocera, Chesias, n. g. {Chesias simulata), 

 n. g. Acidalia dilutata, Cheimatdbia, Lobqpkora, Eupitkecia, Minoa, Baptria, 

 Emmelesia, Hercyna, Hyria, Ptychopoda, Macaria, Ennomos. 



The arrangement is very objectionable, beginning with Psychophora, 

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

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

 in the proposal of desirable new genera, though in this he and Duponchel, as 

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

 work appeared before Duponchel's fourth volume or not is not known. Du- 

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