broad, smooth, on inner side hollowed throughout (cf) into a deep trough filled with a long dense 
expansible hairpencil, terminal joint extremely short, filiform. Maxillary palpi very short, filiform, 
appressed to tongue. Posterior tibiae rough-scaled above. Forewings with 2 and 3 stalked, 7 and 8

273. GENUS TRICHOTAPHE, CLEMENS 
Trichotaphe, Clemens, Proc. Acad. Nat. Sc. Philad. p. 166 (1860). — Type : T. sefosella, Clemens. 
Begoe, Chambers, Canad. Ent. Vol. 4, p. 209 (1872). — Type : T. selosella, Clemens. 
Malacotricha, Zeller, Verh. Zool.-bot. Ges. Wien, Vol. 23, p. 282(1873). — Type : T. setosella, Clemens. 
Gharacters. — Head with appressed scales; ocelli posterior; tongue developed. Antennae 4/5-5/6, 
in Gf ciliated, basal joint moderately elongate, without pecten. Labial palpi very long, recurved, second 
joint thickened with appressed scales beneath, above with scales more or less roughly expanded towards 
apex, terminal joint as long as second, slender, acute. Maxillary palpi very short, filiform, appressed to 
tongue. Posterior tibiae clothed with hairs above. Forewings with r6 furcate, 2 and 3 stalked, 7 and 8 
stalked, 7 to costa, 11 from middle. Hindwings r or over r, trapezoidal, termen slightly sinuate, 
cilia 2/5-3/4; without cubital pecten; 3 and 4 connate, 5 somewhat approximated, 6 and 7 closely 
approximated or stalked. 
Remarks. — Derived from a form approaching Brachia. 
Geographical distribution of species. — Chiefly American, but also fairly represented in the 
Indo-Malayan region, and more scantily in Africa; probably however of Indian origin. 
Larva (10 known) feeding in spun leaves. 
Foodplants especially Comfositae (8), but also Boraginaceae, R'hamnaceae.
