Frontal tubercle bifid ; claws dentated before the extremity ; 

 abdomen rather slender, shorter than the wings, rather long 

 and narrow, only one cross-nervure in the lower basal cell ; 

 no supratriangular nervures ; all the triangles traversed by 

 one nervure : fore wings with the last antenodal cross-nervure 

 continuous ; triangle rather short and broad, followed by 

 three rows of cells, increasing ; subtriangular space consisting 

 of 3 or 4 cells : hind wings with tlie triangle followed by a 

 row of 2 (or the first row of 3) cells, increasing ; its base 

 corresponding with the arculus ; sectors of the triangle united

 sponding to the arculus, the single nervure in the triangle of 

 the fore wings, and the coarse reticulation, &c.

 Barrett-Hamilton, entitled "Note on the Common Hedge-

 The characteristics by which these forms are said to be distin- 

 guished from each other are, to judge from the diagnoses, rather
