188 THE GENERA OF BRITISH MOTHS. 
towards the head, which is brown. It is also distinguished by two rows of dark violet spots. It feeds on the 
leaves of the Convolvulus in August and September, and the perfect insect appears in October. In the perfect 
state it is of very retired habit, and not easily found. It has been recently taken at Lewisham, Bideford, and 
other places. 
The genus Stathimopoda. The insects assigned to this genus have the antenne furnished with delicate 
long hairs. There is but one British species. 
Stathmopoda pedella (the Scarce Stathmopoda). Only a single specimen of this rare species has been taken, 
at Brandon in Suffolk. I have not been able to procure a specimen to make a drawing from. 
The genus Cosmopteryx. The insects assigned to this genus have the head smooth ; the antenne are 
distinguished by a very long basal joint. There are two British species. 
Cosmopteryx Drurella (the Nonpareil, No. 6). This is the Gracillaria eximia of Haworth. It is impos- 
sible on the minute scale of a drawing of the natural size to do justice to the extreme richness and metallic 
enrichment of the colouring of the narrow lancct-shaped wings of this beautiful insect. They are varied with 
black, orange, violet, gold and other blending tints, which, among the several splendid species of the minute 
Tineinw, render it perhaps the most magnificent. Fabricius named this beautiful species after the well-known 
English entomologist Drury, who, it was thought, was the first to discover it ; but this designation seems likely 
to be superseded as a specific distinction by the one more generally adopted—eximia, The larva, which is 
white, delicately streaked with crimson, feeds on Hop, in August and September, and the perfect insect appears 
in the following July. Lewisham, Hackney, and places near London are cited for its capture. 
The other species, C. Lincigiella, is dark fuscous, streaked and speckled with metallic markings, but it is 
not so rare or so splendid as Drurella. 
The genus Batrachedra. The insects contained in this genus, in contradistinction to those of the preceding 
one, have the basal joint of the antenne short. There are two British species. 
Batrachedra preangusta (the Poplar Border, No. 7). The larva of this species feeds on Poplar and 
Willow in May, and the perfect insect appears in July. It is extremely abundant in various localities. 
The other species, B. pinicolella, is of more ochreous tone in the fore-wings, marked indistinctly with brown. 
The genus Oinophila. The insects assigned to this genus have the palpi short and pointing forward, and 
the antennee slender and rather long. There is only one British species. 
Oinophila V-flava (the Yellow V, No. 8). The popular name of this insect arises from the supposed 
resemblance to a V in the principal of the fore wings. The form is, however, very indistinct. The Caterpillar 
is whitish with a brown head, and feeds on Fungi, and also in houses on old corks. 
At Bristol and in London, 
it has been observed in wine vaults in some abundance, 
The genus Chauliodus is principally distinguished by the tooth-like projections on the inner margin of the 
fore wings. There are three British species. 
Chauliodus Iligerellus (the Hook-tipped, No. 9). The front wings of this species are sometimes slightly 
sub-faleate, but scarcely enough to justify the specific name of Hook-tip. The Caterpillar is yellowish green, the 
head being more yellow. It appears in May and June, and the perfect insect in July. It has been recently 
observed in some abundance near Cambridge. 
The other two species are C. insccurellus, the fore wings dull whitish with a pale brown band; and @. 
Cherophyllellus, which has the fore wings of a light brown, with a broad central band of darker tone. 
The genus Laverna. The insects assigned to this genus have raised tufts of scales on the fore wings, and 
the hind wings are very slenderly lancet-shaped, and very pointed. There are eleven British species. 
Laverna atra (the Little Black, No. 10), The popular name has been conferred on this species because 
sometimes the front wings are entirely black ; but these supposed varieties may possibly prove distinct species. 
The Caterpillars feed on Hawthorn berries, in October ; those producing the black variety, however, according 
to Mr. Stainton, feed on the young shoots of Apple. The perfect insect appears in June and is very common. 
The other ten species are—Laverna propinquella ; L. lacteella; L. Staintoni; L. Stephensi; L. Epilobiella ; 
L, cchraccella; L. Phragmitella; L. decorella ; L. subbistrigella ; L. Rhamniella; and L. conturbatella,
