178 Lloyd's natural history. 



GENUS PHYTOMETRA. 



Fhytometra, Haworth, Lepid. Brit. p. 254 (1809) ; Stephens 

 111. Brit. Ent. Haust. ii. p. 121 (1830); Guenee, Spec. 

 Gen. Lepid. Noct. iii. p. 297 (1852); Walker, List Lepid. 

 Ins. Brit. Mus. xiv. p. 1466 (1858). 



Frothymia, Hiibner, Verz. bek. Schmett. p. 282 (1822?). 



In its larval characters this genus comes nearer to the last 

 family than to the x'^.merican genera with which Guenee 

 associates it. The types of Haworth's genus Fhytometra were 

 probably intended to be species of Fltisia, but Flusia may 

 have the priority ; and as Fhytometra viridaria does not con- 

 tradict the characters which Haworth assigned to his genus (as 

 is the case with many of the species which he included in it), 

 it seems better to retain Haworth's name as restricted by 

 Stephens, though Hiibner's later name, Frothymia, was uui- 

 typical, which Fhytometra certainly was not.
