NOCTUIDiE. RUSINA. Ill 



This rare species^ which is theAg.^thiopsofOchsenheimer, (Noctua nigricans 

 of Hiibner) is in very few cabinets. I obtained my specimen from that of the 

 late Mr. Francillon. 



I have known this insect to have been twice captured in the 

 wood upon Shooter's Hill, in June : it has also occurred in Devon- 

 shire. " Cumberland."— 7". Marshall, Esq.

Head and thorax pale griseous-brown ; anterior wings the same, with a longi- 

 tudinal whitish line reacliing from the base to beyond the middle, and giving 

 off three branches in the direction of the nervures towards the anal angle : 

 between this and the costa the stigmata are placed; these are of a pale luteous, 

 with the margin paler ; the space between and on the margin is dusky ; on the 

 inside of the longitudinal line is an elongate lutescent stigmatiform spot, 

 bordered towards the inner edge of the wing with black ; beyond the ordinary 

 stigmata, towards the hinder margin, is a repanded striga of somewhat acute 

 black streaks : the posterior wings are fuscous, with the margins darker and 

 the cilia yellowish : the body is fuscous, and the antennae ferruginous. 



In some examples, the row of black streaks toward the hinder margin is nearly 

 obliterated: others have the anterior wings, with the exception of the stigmata 

 and trifurcate line, of an uniform colour ; while others have the space between 

 the stigmata, and on the hinder margin, deep fuscous: others, again, have the 

 stigmata edged with deep black on a plain ground : in fine, it is a most variable 

 species. 



Caterpillar fuscous with yellowish streaks on the sides and back : — it feeds on 

 various grasses, but, according to Linne, not upon the Alopecurus ; towards the 

 end of June it changes to a brown shining pupa, and the imago appears in 

 about a fortnight. 



Rare in the south of England, but more abundant in the northern 

 districts ; it has been taken at Coombe-wood, and Whittlesea-mere, 

 and in Devonshire. 



Genus XC. — Rusina mihi. 



Palpi ascending, densely squamous, with the terminal joint exposed, rather 

 elongate, composed of three somewhat slender joints, the terminal one being 

 most slender: the basal joint about half the length of the second and a Uttle 

 curved, the terminal one one-third the length of the preceding, elongate, ob- 

 tuse : maxillcB moderate. Antennoe deeply bipectinated in the males, the 

 pectinations suddenly abbreviated towards the apex, ciliated in the females :
