STATHMOPODA. 227 
ii. n. s. 208. pl. xvii. f. 1.—Orpheella, Sta. Alis anticis obscure 
ochreis, fusco-irroratis, dorso dilutiore. Exp. al. 44 lin. 
Head greyish-ochreous, ace dark fuscous. Palpi fuscous, termi- 
nal joint dirty ochreous. Antenne dark fuscous. Anterior wings 
dirty ochreous, coarsely irrorated with fuscous, palest along the inner 
margin ; cilia pale grey. Posterior wings grey, with paler cilia. 
Appears in August and October among Convolvulus arvensis, 
but so retired in habit that it is rarely seen. The larva mines the 
leaves of the C. arvensis in the beginning of August and middle 
of September; sometimes it is very plentiful. 
Genus ll. STATHMOPODA. 
StatumMoropa, Zell. (in litt.) Cosmopteryx p., Hiib.; Zell. Isis, 
1839; Dup. Cat. Hachista p., Dup. L. F. xi. 
Capilli levigati, frons obtusa. Antenne corporis longitudine, setacez, 
articulis elongatis, ¢ tenerrime longe pilose. Palpi labiales longius- 
culi, leves, tenues, recurvi, acuti, articulo secundo compresso. 
Haustellum breve, squamatum. ‘Tibiee postice pilis incrassate, 
longe spinose. Als longissime ciliate, anteriores anguste, pos- 
teriores angustissime ; anteriores : cellula discoidalis elongata, postice 
non clausa; rami quatuor postremi basi libera; venee medianz rami 
tres elongati; submediana postice inerassata; subdorsalis simplex ; 
posteriores: vena costalis (?) furcata, ramo altero in costam, altero 
in marginem posticum exeunte ; mediana ramos quatuor in marginem 
posticum emittit. 
Head smooth, the forehead obtuse. Antenne as long as the body, 
setaceous, with elongate joints, in the @ with very delicate long hairs. 
Labial palpi rather long, smooth, slender, recurved, acute, the second 
joint compressed. Tongue short, clothed with scales. The hinder 
tibiee thickened with hairs, with long spines. Wings with very long 
cilia, the anterior narrow, the posterior extremely narrow. In the an- 
terior wings the elongate discoidal cell is not closed posteriorly; the 
four last branches have the base free; three elongate branches proceed 
from the median vein; the submedian vein is posteriorly thickened ; the 
subdorsal vein is simple. In the posterior wings the costal (?) vein 
is furcate, one branch running into the costa, and the other into the 
hinder margin; the median vein emits four branches to the hinder 
margin. 
Only one species is at present known in this genus; it has 
long been known abroad (though in this country very rare), yet 
its preparatory states still are unascertained ; the Linnean asser- 
tion, “ Habitat in Adni foliis subcutanea,” not having been con- 
firmed, may de entirely erroneous, like the “ Habitat in agi foliis
