6. tetragonana, Steph. Alls anticis fusco-nigris brunneo-nebulosis ; 

 postico plumbeo vel cseruleo variis ; macula medio marginis dorsalis 

 subquadrata alba ; posticis fuscis. tf Exp. al. 6 j 7 Tin. 



Head fuscous. Face slightly paler below. Eyes black. Palpi 

 longer than the head ; above and beneath drab, at base ; the apex 

 grey; sides grey. Antenna3 fuscous; basal joint clothed beneath 

 with light- coloured shining scales. Thorax and patagia fuscous, 

 slightly glossy ; the latter paler at the apex. Anterior wings 

 glossy, with a white dorsal patch, the remainder of the wing 

 suffused with dark brown and still darker streaks and lustrous blue 

 markings. The base is occupied by a dark brown patch (dull fuscous 

 at its origin), streaked transversely, and most intense on its posterior 

 edge, which is angulated in the middle ; it extends one-third along 

 the costa, and two-fifths along the dorsal margin. At the middle of 

 the costa commences the central fascia ; it is narrow at its origin, and 

 somewhat curved in form ; its edges indistinct, and dilates on the 

 dorsal margin towards the base. The apical spot is preceded by four 

 geminated streaks upon the costa ; below these the wing is streaked 

 longitudinally with intense brown, mixed with lustrous blue and red- 

 orange markings. The ocelloid patch formed of two lustrous blue 

 clouds, with black spots edged with orange, between. The dorsal 

 blotch maculated on the margin with fuscous. Apical scales umber. 

 Cilia dusky brown. Posterior wings deep reddish brown. Marginal 

 scales reddish brown. Cilia dark grey. Abdomen fuscous. 



A rather uncommon species, and not subject to variation ; in 

 general appearance it much resembles H. cirsiana, but is smaller ; 

 the dorsal blotch is not so prominent, and more triangular. It 

 is the same size as H. trigeminana. 



The imago appears in July, and occurs throughout England, 

 and also in the vicinity of Edinburgh. 



The larva is from 6 to 6^ lines in length, and may be found in 

 the autumn, full-fed, under moss on the boles of beech-trees in a 

 loose cocoon. In colour it is pale drab, or dirty white, with the 

 spots slightly darker. Head deep hazel-colour. Shield yellowish. 

 It hybernates and goes into pupa in the spring.
