FAM. GELECHIAD/E 49 
3 and 4 separate, 5 rather approximated, 6 and 7 approximated; in cf an expansible fringe or fan of 
strong flattened black bristles (or spines) from beneath costa towards base. 
Remarks. — Probably related to transitional forms between Aísiotelia and. Recurvaria, but the 
curious fringe of bristles is unique. Busck's correction of Chambers with regard to the structure of vein 6 
of forewings (Proc. U. S. Mus. Vol. 25, p. 783) is itself mistaken, and Chambers' original statement is 
correct. 
Geoaraphical distribution of species. — North American. 
Larva unknown.

Leuce, Chambers, Canad. Ent. Vol. 7, p. 51 (1875). — Type : L. fuscocristatella, Chambers. 
Naera, Chambers, ibidem, Vol. 7, p. 9 (1875) (praeocc.). — Type : L. fuscocristatella, Chambers. 
Characters. — Head with appressed scales; tongue developed. Labial palpi moderately long, 
curved, ascending, second joint with large rough tuft of scales beneath, terminal joint shorter than 
second, thickened with scales, hardly pointed. Forewings with tufts of scales on surface; r5 furcate, 
2 from 4/5, 3 and 4 connate from angle, 7 and 8 stalked, 7 to costa, 11 from middle. Hindwings under r, 
elongate-trapezoidal, apex produced, termen sinuate-emarginate; 3 and 4 approximated, 5 rather 
approximated to 4, 6 and 7 remote, nearly parallel. 
Remarks. — Not known to me; seemingly allied to the two following. 
Geographical distribution of species. — North American.

Pachygeneia, Meyrick, Exot. Microlep. Vol. 3, p. 11 (1923). — Type : P. clitellaría, Meyrick. 
Characters. — Head smooth; ocelli posterior; tongue developed. Antennae 4/5, in cf serrulate, 
simple, basal joint moderate, without pecten. Labial palpi moderately long, curved, ascending, second 
joint much thickened with dense scales roughly projecting towards apex beneath, terminal joint as long 
as second, stout, roughened anteriorly, pointed. Maxillary palpi rudimentary. Posterior tibiae rough- 
scaled above. Forewings with tufts of scales; 2 from towards angle, 7 and 8 stalked, 7 to costa, 11 from 
middle. Hindwings under r, narrow-trapezoidal, apex produced, acute, termen emarginate, cilia 1 2/3 ; 
3-5 rather approximated towards base, 6 and 7 somewhat approximated. 
Remarks. — Allied to early forms of Aristotelia. 
Geographical distribution of species. — South American.
