The eighth sub-family of the Zortricide is that of the Sericoridi containing seven genera, Luchromia, 
Orthotania, Notocella, Sideria, Sericoris, Mixodia and Roxana. 
The genus Euchromia. The insects assigned to this genus have the palpi projecting considerably beyond 
the head. The anterior wings are about twice as long as wide; the front edge being regularly arched, and the 
apex rather pointed. There are three British species, representing two sections. The first is distinguished by the 
title Argyroploce as partially corresponding with Hiibner’s genus of that name, and the second distinguished 
by the term Zuchromia as approaching the genus established by Stephens. 
Euchromia fulvipunctana (the Tawney-dotted T, No. 1). This species belongs to the second division. The 
Caterpillar is dark reddish brown with a black head, and feeds upon the common Bilberry (Vaccinium Vitis idea) 
in May. The Moth appears in June and July. It is a northern species, and common on moors in the northern 
counties and in Scotland. 
The other species in the same section of the genus is Z. purpurana, a scarce insect, so named from the 
dull rosy tone of the front wings. In the division Argyroploce the only species is B. arbutella, which like 
Julvipunctana may be considered a northern species. 
The genus Orthotcenta. The two of the three species now assigned to Stephens’ genus Orthotenia are 
by some authors placed in the genus Huchromia, which their characters in some degree justify, while one or more 
were formerly located in the genus Sericoris, The characters of the insects here assigned to the genus Orthotcenia 
are—palpi twice as long as the head, fore-wings more than twice as long as wide, front edge regularly arched, apex 
obtuse. 
Orthotenia striana (the Straight-barred T, No. 2). This insect in the perfect form frequents hedges about 
the middle of June, and is rather common, being sometimes very abundant in the southern counties. The 
other species are, first, O. Hricetana (the Heath T,) originally taken by Mr. Bentley in the north of England, but 
since at Shanklin in the Isle of Wight, Bristol, &. Secondly, 0. antiquana, which is widely distributed, but no- 
where common. 
The genus Notocella. The insects assigned to this genus have the palpi very short and bent downwards. 
The antenne of the males are slightly serrated. The fore-wings are broader and shorter than in the neighbouring 
genera, There is but one British species, 
Notocelia Udmanniana (the Udmannian T, No. 3.) The Caterpillar of this species is unknown. The 
perfect Moth appears in June and is widely dispersed. It is not uncommon in woods or woody lanes.
