This is quito a liomogeneoiis grouj), iti as should plainly be done, we 

 exclude Opcrlioptcru {Chc'uiiatnhid) (Voni il, wjiich, though included in it by 

 M. Guenee, slioulil, I tliiid<, t'orni llic \\\^<' otan equivalent group. 



As regards the larval and pupal eharaeti'rs, we are, from our imperfect 

 knowledge, not in a position (o lay down any characters peculiar to the group. 

 Gueude gives the following characters: " Larvie more or less elongated, with- 

 out any eminence; slightly or 'not at all attenuated, cylindrical, or distinctly 

 flattened; mostly green, with distinct lines; head generally small and globu- 

 lar; living sometimes exposed, sometimes contained in a folded leaf, on trees 

 and low plants. Pupse contained in cocoons." 



As regards the sequence of genera, I have placed Eupithecia first and 

 lowest, in accordance with the plan of arrangement of the species.
