THE GENERA OF BRITISH MOTHS. 1 
Among these, Conturbatella is remarkable for exhibiting very distinetly the generic character of the raised 
tufts of scales on the fore wings, which are bluish black, each having six tufts of raised scales and two conspi- 
cuous white spots. Propinquella has the head and thorax pure white; and Z. S/evensi, the fore wings gray 
varied with tawny. This last species is extremely rare. 
The genus Chrysoclista. The characters which distinguish the insects of this genus are nearly the same as 
those belonging to the last, with the exception that the raised tufts of scales are generally brightly metallic. 
There are four British species. 
Chrysoclista Linneella (the Linnean, No. 11), This species has three tufts of silvery black scales near the 
inner margin of the front wings. The Caterpillar feeds beneath the bark of the Lime and other trees in autumn 
and spring, there being two broods. The perfect insect appears in May and again in July. It is very common 
about the suburbs of London. 
The other three species are the following. C. bimaculella, which resembles the preceding, but has the 
black border of the fore wings broader, except at the front, where the orange reaches to the edge. It is very 
rare. €. Schrankella, which has the front wings bright orange, black at the tips and bases, and some silvery 
lines. C. flavicaput, which may be at once known by the bright yellow head and face, from which it has derived 
its specific name. 
The genus Heliodines. In this genus the perfect insects have the abdomen thicker and shorter than in the 
immediately preceding genera ; and the wings have much less conspicuous tufts of scales. There is but one 
British species. 
Heliodines Resella (the Reesellian, No. 12), This is a very rare species, not lately taken. The larva, which 
is pale green with a black head, feeds upon Chenopodiv® and other plants in June, the perfect inseet appearing in 
July and August. It was formerly taken near London, 
The genus Anybia. The insects assigned to this genus have the wings smooth, that is to say, entirely 
without the raised tufts of scales of the preceding genera. The palpi are recurved. There is but one British 
species. 
Anybia langiella (No. 13). The Caterpillar of this species is green, the head being brown and the second 
segment black. It appears in July, and the perfect insect in August. It has been recently observed at Linton, 
a 
The genus Asychna. The fore wings are narrow, and of a metallic bronzy tone. The hind wings exces- 
at Exeter, and other places. 
sively slender. There are four British species. 
Asychna terminella (the Dalean Asychna, No. 14). The six silvery spots on each of the fore wings of this 
pretty little insect make it somewhat conspicuous, though the dots in themselves are small. The Caterpillar is 
whitish with a brown head. It feeds on Cirewa Entetiana, in September and October, and the perfect insect 
appears in the following June. It has lately been noticed at § 
arborough in great abundance. 
The other species, A. modestella, A. fuscociliclla, and A. eratella, have the front wings nearly unicolorous, 
of bronzy green or brownish. A. fuscociliella, which is of a grayish bronze tone, is very rare. 
The genus Chrysocorys. The insects assigned to this genus have the antenne thick and short, the front 
wings narrow, and the front edge waved, getting convex near the tip. There is only one British species. 
Chrysocorys festaliella (the Narrow-winged, No. 15). The Caterpillar of this species is pale green and 
slightly bristly, feeding on the underside of the leaves of the Rubus family in August. The perfect insect appears 
in June and July. It is common, and in many places very abundant. 
The genus Stephensia. The insects assigned to this genus, which is newly added to the British list, have 
the palpi pointing downward and the fore wings narrow, with the front edge concave near the middle. There is 
only one British species. 
Stephensia Brunnichella (the Brunnichean). I have not been able to proenre a specimen of this new 
species to draw from, and must therefore be content with a description which Mr. Stainton gives, as follows. 
“The fore wings are dark golden brown, with a golden fascia close to the base ; a slender bright golden fascia in 
the middle, a golden spot perpendicularly placed at the anal angle, and one beyond it on the costa, pointing
