262 HAUSTELLATA. LEPIDOPTERA. 



genus Larentia of Duponcliel and Curtis, but not one of Oclisen- 

 heimer's species of that genus belongs thereto, consequently it 

 becomes necessary to employ a different term here ; the error of 

 the above writers arising from their having attended to the mere 

 name of the typical species (La. cervinata, see p. 211), without 

 taking the pains to investigate beyond, which had they done they 

 might have ascertained that Hiibner's original Ge. cervinata (since 

 changed by him to Ge. certata) was not the La. cervinata of 

 Ochsenheimer, but belonged to a different genus.

Griseous-brown ; anterior wings with various obsolete strigse or fasciolas at the 

 base, two narrow stouter fasciae in the middle, of which the exterior is some- 

 what triangulated, and between them is a short black line a little within the 

 costa — the fascia are frequently united in the middle, and form a broad in- 

 solid central band — towards the hinder margin is an undulated pale striga, 

 and on the hinder margin itself a slightly interrupted black line : cilia with 

 obscure dusky clouds; posterior wings fuscous, with various darker waved 

 paler and darker strigse, and a distinct central dot : ciUa obscurely clouded. 



Varies considerably in colour: one example that I possess has the ground colour 

 of the wings very pale, with the central fascia very distinct ; another is almost 

 entirely of a deep fuscous, with the usual lines and strigse darker, and the 

 costa of the anterior wings clouded with pale cinereous. 



Caterpillar with the head brown, the back grayish, with paler stripes on the 

 sides, the underside pale with green spots ; it feeds on the barberry (Barberis 

 vulgaris) : — the imago appears in April. 



Rare: I have taken specimens in the neighbourhood of London, 

 and it has occurred in other parts.

Fuscous, shining: anterior wings with a brilliant tinge of purple, the base with 

 numerous dark crenated strigae and paler intermediate ones; towards the middle 

 is a broader dark one, forming as it were the outline of a central fascia, and 

 behind the middle is a second, which composes the same ; this has a sharp
