wings are alternately fasciatetl traversely with fuscous and cinereous ; and the 

 width of the marginal fimhria on the posterior wings varies considerably. 

 Caterpillar feeds upon poplars and willows: it is yellowish-green, with a bluish- 

 black lateral line, and some black spots :— the imago appears towards tlie end 

 of March. 



Near Hertford, Highgate, Colney-liatch, and Coombe-wood, I 

 have occasionally seen and captured specimens of this insect, which 

 is in certain seasons not uncommon : it also occurs at Birch and 

 Darenth woods. " Ongar Park woods." — Mr. Douhleday.

Fuscous : anterior wings fuscous-ash, with obsolete darker fasciae, nearly as in 

 the foregoing species : posterior wings luteous, with a broad, somewhat rounded 

 central fascia at the base, and the hinder margin black ; cilia cinereous : 

 female paler, with the fasciie more distinct. 



The luteous posterior wings at once distinguish this insect from its congeners. 



Caterpillar violet, with white dorsal and lateral lines; and two spots on the middle 

 segment under the dorsal line : it feeds on the aspen. 



A single specimen of this insect is in the collection at the British 

 Museum : of its origin 1 am not aware, but I believe it was obtained 

 byDr. Leach from Dr. Lettsom's collection.
