nothing of its habits. Schliiger says of it, “The larva mines the 
leaves of Epilobium hirsutum, occurring at the same time as Hpi- 
lobiella. he perfect insect appears at the end of July and in 
August: it is uncommonly abundant, since there are often from 
thirty to forty larvae on one plant.”

Head bronze, Face white. Palpi, the second joint white, the ter- 
minal joint black. Antennee dark fuscous. Anterior wings shining 
bronze, with a transverse sxow-white spot above the fold, beyond the 
middle; between this and the base are a few white scales in the fold, 
and a few others lie between it and the apex of the wing; cilia bronzy- 
grey. Posterior wings bronzy-grey, with grey cilia. 
A specimen is in Mr. Shepherd’s collection, and one in the col- 
lection of the British Museum. 
Genus XI. ASYCHNA. 
Asycouna, n. g. lachista p., Zell. 
Capilli leves. Antenne setacew, articulo basali elongato, clavato. 
Palpi labiales mediocres, curvi, articulo secundo compresso, tertio 
breviore acuto. Haustellum mediocre, squamatum, Alze longissime 
ciliate, anteriores wvicolores, metallic, anguste, posteriores lineari- 
lanceolate. Anteriores: vena apicalis fureata, supra et infra apicem 
exit, infra eam venze dus, cellula discoidalis postice dilatata; sub- 
dorsalis furcata, furca imperfecta; submediana non inerassata ; pos- 
teriores: ven mediane rami tres, obsoleti, vena discoidalis simplex, 
apicalis simplex. 
Head smooth. Antenne setaceous, the basal joint elongate, clavate. 
Labial palpi of moderate length, curved, the second joint compressed, 
the third joint shorter, acute. ‘Tongue of moderate length, clothed 
with scales. Wings with very long cilia, the anterior unicolovous, me- 
tallic, narrow, the posterior linear-lanceolate. In the anterior wings 
the furcate apical vein runs out above and below the apex, below it are 
two veins; the discoidal cell is dilated -posteriorly, the subdorsal vein 
is furcate, but the lower branch of the fork is abbreviated, the sub- 
median is not thickened; in the posterior wings the median vein has 
three obsolete branches, the discoidal and apical veins are simple. 
Of the four species I have placed in this genus, the first two 
only really belong here, the other two showing several discre- 
pancies ; [ was unwilling to multiply the genera here to so great 
an extent as the formation of separate genera for @rateld/a and
