156 IIAUSTELLATA. — LEPIDOI'TERA. 



constancy of appearance is of more consequence in determining a species, than 

 a few varieties in the markings." 



Found with the precedintr species in the metropolitan district : 

 near Darenth-wood especially, where I have taken it abundantly.

Closely allied to the last ; from which it differs in being of a darker hue, m ith 

 the ordinary stigmata distinct and brown, with faint pale edges, and having 

 an obscure angulated striga passing between them : the pale striga towards 

 the hinder margin of the wings is scarcely undulated, and in some examples 

 is nearly straight : the posterior wings are dusky, especially in the females. 



Caterpillar ashy-gray, with reddish lateral line and brown head : it feeds on 

 plantain : the imago appears in June. 



Not very common, frequenting gardens : found throughout the 

 metropolitan district. I have received the insect from the New 

 Forest and from Devonshire. 



Sp. 4. implexa. Alls anticis griseo-ferrugineis sirigis quatuor saturatiorihus

 hn.)

Paler than the preceding insect: head, thorax, and anterior wings rusty or yel- 

 lowish-griseous, with four distinct darker or fuscous strigae, the first abbreviated 

 at the base, the second rather obhque and considerably undulated, the third 

 placed between the stigmata, broad and subrectangular; the fourth much 

 arcuated, composed of lunules, and placed behind the posterior stigma; between 

 which and the hinder margin is a distinct and strongly waved pale one, edged 

 internally with fuscous ; on the margin itself is an interrupted black Une : 

 posterior wings pale ochraceous brown, the base paler, the hinder margin with 

 an interrupted black line, as in the anterior wings. 



Known by its paler hue, and the distinctness and number of the transverse 

 strigae on the anterior wings, and especially by the greater undulation of the 

 pale posterior striga. 



I have frequently captured this insect at Darenth-wood, par- 

 ticularly one evening in July, 1820, when, in company with my late 

 friend, Mr. Blunt and his brother, the Rev. W. Blunt, we secured 

 nearly 800 specimens of Noctuidse, in less than four hours, amongst 

 which M'cre no less than 51 species, including, amongst others equally 

 rare, two examples of Thyatira batis.
