Ochsenheimer's Genera of the Lepidoptera of Europe. 101 



anteriorly and posteriorly bifid : abdovicti moderate, 

 scarcely tufted on the back and sides, the apex with a 

 small tuft, obtuse in the males, acute in the females. 

 Larva naked; pupa subterranean*. 



Ochsenheimer, or rather Treitschke, has divided this genus 

 into four families. 

 Fam. a. — With a very bright white or yellow reniform spot 



on the fore-wings. 

 Fam. B. — Small species (N. Pusillse, Fam. V. Wien. Verz.), 



with bright metallic markings on the fore-wings. 

 Fam. C. — Larger, generally dark coloured, species, with the 



fore-wings long, and rounded at the extremities. 

 Fam. D. — Colour inclining to copper-red, with the fore-wings 

 shorter, and pointed at the extremities.
