Head glaucous-ash ; thorax the same, with its anterior margin, or collar, black 

 or fuscous ; anterior wings of a glaucous-ash, sprinkled throughout transversely 

 with numerous minute dusky lineolse, with an obscure transverse, nearly 

 straight, striga before the middle, and a broad pale fuscous fimbria on the 

 posterior margin ; in the place of the anterior stigma is a minute black dot, 

 and in that of the posterior, a somewhat triangular or lunate black mark with 

 a minute dot adjoining its posterior apex ; cilia pale glaucous-ash : posterior 

 wings fuscescent, with a darker margin ; cilia pale ash. 



In some examples the posterior wings are entirely fuscous. 



Caterpillar greenish -ash, spotted with black, with two dark lines and an in- 

 terrupted yellow one between ; it feeds on the astragalus glycyphyllus .-—the 

 imago appears towards the beginning of August. 



Taken occasionally in the fields in the neighbourhood of Birch 

 and Darenth woods, and I believe sometimes near Coombe ; but the 

 former are its usual haunts, the food of the larva occurring in plenty 

 in some parts of Darenth-wood. " York." — W. C. Hewitson, Esq.

Anterior wings fuscous, with a dot and central patch black, and two very ob- 

 solete strigae towards the apex ; the posterior wings also fuscous. 



A single example only of this rare insect, which considerably

 is, however, not aware of its locality, it having been introduced, 

 with other rarities, by his father.

Head and thorax ashy-brown : anterior wings of a griseous-brown, palest at the 

 base, with a broad darker obtuse fascia before the middle, and a second less 

 distinct and divaricating behind the middle, these fascia gradually shaded off 

 into the ground colour of the wing on their outer edge ; and between them is 

 an obscure dusky waved striga : in the place of the anterior stigma is a minute 

 black dot, and in that of the posterior an obscure wedge-formed patch ; on 

 the costa near the apex is an oblique black streak, composed of three or four 

 somewhat triangular spots: on the hinder margin is an indistinct series of
