2S'8 HAUSTELLATA. LEPIDOPTERA. 



of the contour and markings of the wings, but in the structure and 

 length of its palpi, and by the diversity of the larva : — the species 

 are extremely prone to vary — whence the name I have employed 

 to designate them — and appear to have been all confounded under 

 one by every continental writer, but that most of them are clearly 

 distinct must be evident to all practical entomologists.

Ph. immanata, Haworth. — Ha. immanata. Steph. Catal. part ii. p. 134. No. 

 6570. 



Anterior wings cinereous, with a slender dentate or angulated solid black fascia 

 at the base, followed by a griseous one and a broad solid one in the middle, 

 crenated within and strongly and irregularly dentate without, the middle 

 produced into two lobes, the costal one being bifid : adjoining to this is a large 

 whitish costal spot, more or less continued to the inner margin, and gradually 

 shaded into bright fuscous or ferruginous; beyond this is a waved white 

 striga; towards the hinder margin are some wedge-shaped fuscous spots; and on 

 the hinder margin itself is an interrupted black line : posterior wings fuscous- 

 ash, with a central dot and an angulated striga darker ; the margin from the 

 latter paler, and sometimes slightly mottled with dusky. 



Extremely variable in tint, and slightly in the width of the central fascia, which 

 latter is always more strongly produced in the middle of the outer edge than 

 in the following species, and more acute; in some cases this fascia is slightly 

 unsolid, its centre being cinerascent, with a distinct black dot and some dark 

 waved lines ; in others it is tinged with ferruginous. 



Not very uncommon in w^oody places in the beginning of July,

Ha. amsenata. Steph. Catal. part ii. p. 134-. No. 6571. 



Anterior wings rather narrow, ashy- white, with the base black, its outer edge 

 very much angulated; this is followed by a narrow irregularly angulated 

 fascia clouded with fuscous, beyond which is a very broad black fascia, den- 

 tate within and very much produced in the middle of its outer margin, the 

 process being composed of two lobes, of which the first is very broad and 

 bifid, and the inner and shorter one very acute and simple ; this fascia is bor- 

 dered posteriorly by a broad white striga, beyond which the hinder margin is 

 clouded with fuscous, and has a very distinct undulated white striga : posterior 

 wings whitish, with a fuscous dot on the disc.
