There is no good reason why these names should noi stand, as observed 

 by Dr. I,. Harvey as well as by Mr. Scudder,* who called the attention of 

 entomologists to this neglected publication. 



In 1818, Hiibnerf published the part of (he "Verzei.chitiss" relating to 

 the Phalcenidos, which are grouped under the name Geometrce, forming his 

 •' Phalanx quinta." He divides the group into three tribes, the tribes into 

 stirps, and the latter into families, genera, and species. 



Tribe I, stirps i-ii comprises the modern Geometrince ; stirps iii, part of 

 GrueneVs Ennomidce; stirps iv contains the Uranides, and a part of the Enno- 

 m'nur; stirps v comprises the Fidoniinoe, some Ennominte, and Semiothisa; 

 stirps vi comprises, among other genera, Lythria, Hcematopw and Calothysanis. 



Tribe II, stirps i contains, among other genera, Codonia ; stirps ii, 

 Orthostixis, Rhyparia, Panthera, Baptria, etc. ; stirps iii comprises certain 

 Acidalinai and the Caberinee ; stirps iv comprises the Hiibnerian genera 

 Scotopteryx, Catascia, Ascotis, Dyscia, etc. ; stirps v comprises Cymatophora, 

 "or GrueneVs Boarmidee. 



Tribe III, stirps i comprises the modern genera Amphidasys, Bistort, 

 Phigalia, Nyssia, etc.: stirps ii contains Operophtera, Oporiniu,Hydriomc)in, 

 Trickopteryx, the groups represented by Evpithecia, etc.; stirps iii includes, 

 among other genera. Melanippe ; stirps iv comprise Calocalpe, Plerocymia, 

 etc., and Glaucopteryx ; stirps v, and last, Ochyria, Lygris, Car.sia, Litlto- 

 stege, etc. 



from this arrangement it will be seen that Hiibner placed the Geome- 

 tiimc above even I rania and the Ennomidte of Guenee, while his third tribe 

 is a mixture of certain of GuencVs Boarmidee with the Larentidce. Here
