TORTRICINA. 303 



the base fuscous, merging into umber towards the apex ; the caudal 

 tuft ochreous. $ Exp. al. 6-6| lin. 



A scarce species, and apparently local. It is very closely 

 allied to Eup. angustana, and with difficulty distinguished from 

 it ; it differs, however, in having a coarse, broad, curved, oblique, 

 dull ochreous and umber streak across the apical angle : hence the 

 name " curvistrigana." The central fascia is widest on the costa, 

 and the costa itself more rounded than in angustana. 



The imago appears in May and June. It has been captured 

 by Mr. H. Tompkins near Lewes in Sussex, among mixed 

 growth ; and by Mr. P. H. Vaughan near Bristol, among young 

 Ash trees.

Head : over and behind the eyes ochreous, on the vertex primrose- 

 colour. Face primrose- colour. Eyes black. Palpi as long as the 

 head, above and between pale primrose- colour ; at the sides and be- 

 neath inclining to ochreous. Antenna3 fuscous. Thorax ochreous 

 in front, primrose -colour on the vertex, crested behind. Patagia 

 ochreous, paler at the apex. Anterior wings very glossy, pale straw- 

 or primrose-colour, clouded with ochreous, with umber and rich 

 brown markings in the middle and at the apex. The base clouded 

 ochreous. Before the middle is a mottled umber fascia, very irre- 

 gular, undefined and indented through two-thirds of its course, then 

 well-marked to the dorsal margin, where it terminates in an oblong, 

 quadrate patch ; it is wide and suffused at its origin, constricted at 

 the middle, and edged anteriorly towards the costa with lustrous 

 blue scales. Beyond this fascia, but close to it and the dorsal 

 margin, is a dusky ochreous patch, followed by another of similar 

 colour, in the apical region. The apical margin broadly umber, 

 speckled with black ; the apex ferruginous. The costa and dorsal 

 margin finely speckled : on the latter, near the anal angle, is a small 

 sharply-defined, somewhat triangular spot. Apical scales dark um- 

 ber, with iron-grey bases. Cilia umber at the apex, the remainder 

 dark iron-grey, sometimes mottled with dusky ochreous. Posterior 

 wings dark grey beneath, mottled with umber ; above with a sub- 

 dued gloss, rich fuscous, palest at the base. Marginal scales glossy, 

 fuscous, with dull ochreous bases. Cilia dusky grey. Abdomen 

 glossy, rich fuscous ; the apex dull ochreous. $ Exp. al. 6-7 lin. 

 Anterior wings marked as in the rf , but richer in the colouring. 



A common species ; variable in size, and very so in colour ; 

 closely resembling Eup. curvistrigana, but wants the curved streak
