192 THE GENERA OF BRITISH MOTHS. 
The other species ave C. laburnella, C. Wailesella, C. scitella, and C. Lotella. Among these C. scitella 
is the handsomest. The front wings ave full deep gray, delicately streaked with white aud brown, and 
ornamented with a rich coppery blotch, aud a well-defined black dot, which has a central speck of glittering 
metallic violet. 
The genus Opostega. The insects assigned to this genus have the head rough in front; the antenne have 
the projecting basal joint or eye-cap very large ; the fore wings are rather blunt at the apex. There are three 
British species. 
Opostega auritella (the Eared, No. 24). Both the specific and popular names of this species have reference 
to the remarkable enlargement of the basal joint of the antenne, the projections having somewhat the appearance 
of ears, though better described as eye-caps. The Caterpillar of this speciesis unknown. The perfect insect is 
taken in the Fens of Cambridgeshire in June, but it is rare. 
The other species are 0. salaciella and O. crepusculella. The first has the front wings white without 
spot or mark, but with a faint yellow tinge. The second is also white, but variegated with strongly angulated 
cross bars of brown. “. 
The genus Bucculatriz. The insects assigned to this genus have the head tufted ; the antennw short, and 
rather robust, but with the basal joint less than in the preceding genus. The-palpi are absent. This genus is 
the least attractive of the group. There are eleven British species. 
Bucculatrix Ulnella (the Elm Bucculatrix, No. 25). The Caterpillar of this species is pale olive-gray, with 
a brown head. It feeds on the foliage of the Oak, in July and September. The perfect insect appears in May 
and August. It has been recently observed in some plenty at Bristol, Plymouth, and other places. 
The other species are B. aurimaculelia, B. cidarclla, B. Crategi, B. Demargella, B. maritima, B. 
Boyerclla, B. Frangulella, B. Hippocastanctla and B. eristatella. Among these, B. aurimaculella, with the front 
wings bronzy gray, with two yellow spots, and B. cidarella, with the front wings purplish brown, relieved 
with two white spots, are the only species at all remarkable. The colours of nearly all the others are dull and 
confused. 
The thirteenth family of the sub-division Tincina is that of Nepticulide. In this group the head is 
hairy, the antenne short and thick, but with the basal joint as in the last family. The maxillary palpi are well 
developed, and folded. The fore wings are broad and short. The Caterpillars are nearly maggot-formed, the 
rudimental feet, however, exceeding in number those of the most highly developed Caterpillars, and consist of nine 
pairs. They are leaf-miners. This family comprises only three genera, but the first and typical genus, Nepticula, 
contains alone forty-two species ; the other genus, Zrifureula, only four, and the last, Bohemannia, only one. 
Among these thirty-four species are to be found the smallest of known Moths, while some of the most, minute of 
these, as if to make up for their microscopic size, are truly resplendent in rich colours, and brilliant metallic 
markings of gold, silver, and bronze. : 
The genus Nepticula. The characters detailed in defining the main features which distinguish the family, 
apply also to this genus, which is the typical one. 
Nepticula floslactetla (the Creamy Pigmy, No. 26). The Caterpillar of this minute species is of a pale 
yellow colour ; it feeds on the leaves of the Nut and Hornbeam, in July and October ; the Moth appearing in May 
and August. It is abundant almost everywhere. 
The other species are :—N. atricapitella ; N. ruficapitella; N. pygmeella ; N. Pomella ; N. Oxyacanthella ; 
N. viscerella ; N. anomatella; N. cryptella; N. Catharticella ; N. Septembrella; N. intimella ; N. Headleyella ; 
N. Weaveri; N. subbimaculella ; N. argyropexa ; N. apicella ; NV. sericopeza; N. trimaculella ; N. quinquella ; 
N. Salicis; N. Myrtilella; N. lutzella; N. ignobilella; N. areuata; N. angulifasciclla; N. atricollis; N. 
microthericlla ; N. Poterti; N. argentipedella ; N. Acctosa; N. betulicola; N. Plagicolella; N. Malella; N. 
Tityrella ; N. Glutinosa ; N. gratiosella; N. Prunctorum; N. Regiclla ; N. continuella ; N. Alnetella ; N. mar- 
ginicolella, and N. wurella. 
Among these may be particularised for their rich colours and glittering metallic gloss, the following :— 
N. ignobilella, with the fore wings light golden brown, with a distinct shining band of delicate straw-colour, the
