190 THE GENERA OF BRITISH MOTHS. 
inwards.” The Caterpillar is greenish white, with a black head. The perfect insect appears in May and again in 
July, and has been taken at Bristol in some plenty, and at a few other places sparingly. 
The genus Elachistw. The insects assigned to this genus have the palpi slender and recurved ; the fore 
wings generally long and narrow, and the hind wings very narrow and pointed. These characters are, however, 
subject to considerable modification in the different species, which amount to forty-one in number. 
Llachista Pfeiterclla (the Four-spotted Gold, No. 16). The coppery golden tone of the ground colour of 
the fore wings of this pretty species cannot be imitated in a representation, Two of the bright gold spots 
are sometimes spread into one, This insect is taken in the Kentish woods about the end of May, but little is 
known of its habits, and it is very rare. 
Blachista albinella (Albin’s Elachista, No. 17). This species is taken in June in woody districts. 
The other species of Llachista are :—E. Treitschkiella; E. Gleichenella; E. Brunnichella ; E. magnificella ; 
EL. apicipunctella ; E. albifrontella ; B. Holdenella ; E. atricomella; E. luticometia ; E. Kilmunella; BE. alpi- 
nella; E. einereopunctella ; EB. trapexiella; BE, nigrella; E. subnigrella; E. occultella; E. consortella; EB. 
pulehella ; EB. Bedellella ; E. obscwrella ; E. zonariella ; EB. gungabella ; E. obliquella ; E. abruptella ; E. Meger- 
lella ; E. adscitella; E. cerusella ; B. Rhynchosporella ; E. Eleochariclla; EB. biatomella; BE. serricornis; E. triatomea ; 
EL, triseriatella ; E. collitella ; E. pollinariella ; E. rufocinerea ; E. ochreella ; and E. eygnipennelta. 
This genus has been remodelled by Mr. Stainton since the Museum arrangement which I am following 
was adopted, and some of the species have been otherwise located. Many of them are, however, retained, and 
among them the following, which illustrate three or four sections of this extensive genus. Z. magnificella is 
one of the moderately large species. The fore wings are rich brown, with a pale gold band and gold spots. 
E. triatomea is of about the same size, and has the front Wings white with three black dots. Z. cerusella is one 
of the largest of the genus, the fore wings being white, with brown and black markings. 2. eygnipennella, the 
‘*Swan Feather,” is perhaps the largest of the genus, and is pure white without spot or mark. Z. Bedelleltu is, 
on the other hand, one of the smallest species, and has the fore wings gray, with a white band and dots. 
The genus Tischeria. In this genus the antenne of the males are short, and furnished with long and 
slender hairs ; the palpi are slender and drooping. ‘The legs of the larve are imperfectly developed. They are 
leaf-miners. There are four British species. 
Tischeria complanella (the Red Feathét; No. 18). The Caterpillar feeds in Oak leaves in September and 
October, and the perfect insect appears in the following June. It is an abundant species almost everywhere. 
The other three species are—Z. Dodonwa, with the front wings bright straw-colour, clouded with gray ; 
7. marginca, with the front wings clear pale yellow bordered with brownish ; and Z. aagusticollella, with the 
front wings purplish brown, with a bronzy patch at the base. 
The eleventh family of the sub-division Tineina is that of the Lithocolletide. The general characteristics 
of the insects located under the present family denomination are—head rough, labial palpi slender and drooping, 
fore wings of long proportion, and hind wings very narrow and pointed, with long fringes. The most distinetive 
mark is that appertaining to the larva stage, the Caterpillars having only fourteen legs. They are leaf- 
miners, 
The forty-five species comprised in this compact family all belong to a single genus. But though they are 
sufficiently homogeneous in general character to exhibit good generic affinities, they are very various in their 
markings and aspects as regards colour and its distribution, and some of them are among the most brilliantly 
tinted and prettily marked in the whole range of British Micro-lepidoptera. Most of the species pass the winter 
in the chrysalis stage, and are double-brooded. 
The genus Lithocolletis, as the only one of the family, necessarily presents the precise characteristics 
previously described in defining the distinctive features of the family. There are, as before stated, forty-five 
British species. 
Lithocolletis corylifoliella (the Hazel Red, No. 19). The Caterpillar of this species feeds beneath the upper 
surface of the leaves of Hawthorn, in July and September. The perfect insect appears in May and August. It 
is 4 common species, often excessively abundant,
