cillaria p., Haw.; Curt.; Dup. L. F. xi. Ornia p., Treit.; Zett. 
Gracillaria p. et Buspilapteryx, Step. 
Caput superne ac in fronte levigatum. Ocelli nulli. Antenne alarum 
anteriorum longitudine wquantes, tenues, articulo basali elongato, 
incrassato. Haustellum squamatum. Palpi maxillares longiusculi, 
filiformes. Palpi labiales tenues, adscendentes, cylindrici, articulo 
secundo squamis appressis, zon fasciculato, articulo tertio acuminato. 
Ale longe ciliate, anteriores elongate, posteriores lanceolate: ; an- 
teriores; vena subcostalis basim versus interrupta, e cellule discoi- 
dalis parte postica venze novem oriuntur, quatuor in costam, quinque 
in marginem posticum exeuntibus ; subdorsalis simplex ; posteriores: 
vena apicalis ante apicem exit, infra eam vena furcata, vena mediana 
trifida. 
Head above and in front smooth. Ocelli none. Antenne as long 
as the anterior wings, slender; the basal joint elongate, thickened. 
Tongue clothed with scales. Maxillary palpi rather long, filiform. 
Labial palpi slender, ascending, cylindrical; the second joint with ap- 
pressed scales, not tufted; the terminal joint pointed. Wings with 
long cilia, the anterior elongate, the posterior lanceolate. In the an- 
terior wings the subcostal vein is interrupted towards the base; from 
the hinder portion of the discoidal cell nine veins proceed, of which 
four go into the costa, and five into the hinder margin; the subdorsal 
vein is simple; in the posterior wings the apical vein terminates above 
the apex, below it is a furcate vein; the median vein is trifid. 
In the small species of this genus, the maxillary palpi are less de- 
veloped, and the labial palpi are almost drooping. 
The species of this genus are elegant in form and frequently 
gaily coloured, or prettily mottled. Some species are double- 
brooded, the autumnal brood generally hybernating, and being 
met with in wasted condition in the spring; they feed upon low 
plants, as well as upon shrubs and trees. The larvae have only 
fourteen feet; when young they mine the leaves, but at a later 
period of growth many of the species construct cones, by rolling 
up a portion of a leaf; they devour the inner portion of these 
cones, which thus become discoloured and are easily observed. 
The species of the genus may be arranged in the following 
table :— 
a. Large species. 
6. Anterior wings with a distinct paler trigonal mark on the costa. 
Species 1, 2. 
6b. Anterior wings with a more or less distinctly margined, but 
hardly paler trigonal mark on the costa. Species 3-8.
