138. GENUs SOROTACTA, MEYRICK 
Sorotacta, Meyrick, Trans. Ent. Soc. Lond. p. 253 (1914). — Type : S. viridaus, Mevrick. 
Characters. — Head smooth; ocelli posterior; tongue developed. Antennae 4/5, basal joint 
elongate, without pecten. Labial palpi very long, recurved, second joint thickened with dense scales, 
considerably expanded towards apex, somewhat projecting-angularly above and beneath, terminal joint 
as long as second, with rough projecting scales posteriorly except towards apex, acute. Maxillary palpi 
very short, filiform, appressed to tongue. Posterior tibiae clothed with hairs above. Forewings with tufts 
of scales; r5 furcate, 2 from towards angle, 7 and 8 stalked, 7 to costa, 11 from middle. Hindwings r1, 
elongate-trapezoidal, apex obtuse-pointed, termen slightly bisinuate, cilia 1 1/2; with cubital pecten; 
3 and 4 connate, 5 somewhat approximated, 6 and 7 closely approximated towards base. 
Remarks. — Probably derived from Alsodryas. 
Geographica! distribution of species. — South American. 
Larva unknown; but considering the stronglv marked adaptation of the imago in this and the 
next genus to lichen-covered tree-trunks, it is likely that the larval habit may be similar to that of the 
preceding genus.

Alsodryas, Meyrick, Trans. Ent. Soc. Lond. p. 250 (1914). — Type : A. laclaria, Meyrick. 
Characters. — Head smooth; ocelli posterior; tongue developed. Antennae 4/5, in c simple, 
basal joint elongate, without pecten. Labial palpi long. recurved, second joint densely scaled, with 
rough projecting scales or strong triangular tuft at apex beneath, terminal joint as long as second or 
longer, thickened with scales and slightly roughened anteriorly, acute. Maxillary palpi very short,

scales; 15 furcate, 2 from towards angle, 7 and 8 stalked, 7 to costa, 11 from middle. Hindwings r,

connate, 5 nearly parallel, 6 and 7 closely approximated towards base. 
Remarks. — A derivative of Anacamfsis. 
Geographical distribution of species. — South American. 
Larva unknown.
