Tue fourth family of the sub-division Tineina is that of the Hyponomeutide. It comprises six generas, 
which, collectively, contain nineteen species. Some of these are among our most common and abundant species, 
and in their larva state the most destructive to the foliage of our fruit trees. Others are, on the contrary, of 
extreme rarity, and among the most beautiful of our Micro-lepidoptera. j 
The genus Swammerdamia. The insects assigned to this genus have the head thickly clothed with erect 
hairs, and the hind-wings have a transparent patch at the base. The Caterpillars feed in a web on the surface of 
leayes, and the Chrysalis is formed in a closely woven cocoon. There are five British species. 
Swammerdamia apicella (the Peacock’s Feather, No. 1). The Caterpillar of this species feeds on the 
Plum ; the perfect insect appears in April and May. It is very abundant. 
The other species are S. cwsiella, S. griseocupitella, S. lutarea, and S. Pyrella. 
The genus Scythropia. The insects assigned to this genus have the head rough, the palpi drooping, and 
the hind-wings with no transparent patch. The Caterpillars are gregarious, while those of the last genus are 
solitary. There is only one British species, 
Scythropia Crateegella (the White-horn Bar, No. 2). The Caterpillar of this species is dull reddish brown, 
and feeds in groups in a common web, upon Hawthorn, in June. The perfect insect appears in July, and has 
been recently taken in sufficient plenty at Bristol, Cambridge, Plymouth, Lewisham, &c. 
The genus Hyponomeuta. The insects assigned to this genus have the head smooth, the palpi short and 
reflexed, and the hind-wings with a distinct transparent patch. The Caterpillars feed in groups, and form a 
cocoon for the Chrysalis. The genus comprises the common though pretty Moths known as the Ermines, from 
their whitish gray wings spotted with black. There are six species. 
Hyponomeuta Evonymellus (the Allied Ermine, No, 3). This species may be known by the distinctness 
of its three rows of black specks. The Caterpillar is of a dusky yellow with black spots, and feeds on Spindle 
in May and June. The perfect insect appears in July and August, and is very abundant, 
The other species are H. Viginti-punctatus, H. plumbellus, H. irrorellus, H. padellus, and H. Padi. Of 
these H. irrorellus, distinguished by the irregularity of the spots and by a large dusky patch near the apex, is 
the most rare. H. plumbella has the hind-wings brown, and appears chiefly in the southern counties, but is 
nowhere very common. 
The genus Anesychia. The insects assigned to this genus have the palpi moderately long and reflexed, 
and the hind-wings are without a transparent patch at the base. The Caterpillars are slightly pubescent and 
longitudinally streaked with different colours ; they are solitary, and feed surrounded with web on the foliage of 
several plants belonging to the order Boraginacee. There are four British species.
