164 LEPIDOPTERA HETEROCERA 
213. GENUS DACTYLETHRA, MEYRICK 
Dactylethra, Meyrick, Journ. Bombay Nat. Hist. Soc. Vol. 17, p. 153 (1906). — Type : D. candida, 
Stainton. 
Characters. — Head with appressed scales, sidetufts loosely spreading ; ocelli posterior; tongue 
developed. Antennae 4/5, in C'sserrulate, simple, basal joint moderate, without pecten. Labial palpi 
long, curved, ascending, second joint with long tuft of loose spreading scales beneath, terminal joint as 
long as second, loosely scaled, acute, with several black rings. Maxillary palpi very short, filiform, 
appressed to tongue. Posterior tibiae rough-haired above. Forewings with 15 furcate, 2 from near angle, 
2-4 paraliel, 7 and 8 stalked, 7 to costa, 11 from middle. Hindwings r, trapezoidal, apex obtuse, termen 
faintly sinuate, cilia 4/5; 2 remote, 3 and 4 connate or nearly approximated, 5 slightly approximated, 
6 and 7 stalked. | 
Remarks. — This genus, which must closely approach the primitive form of the whole group, 
may be derived from a form of the Dichomeris group. 
Geographica! distribution of species. — Indian and African, with a species in Siberia 
Larva (candida) feeding in galls formed on seed-pods. 
Foodplants Leguminosae.

Group 7 (Dichomeris type) 
A considerable group in general recognisable by the characteristic palpi, which have the second 
' joint usually variously tufted or expanded beneath or above or both, the terminal long and acute; the 
forewings have veins 2 and 3 asa rule stalked (yet exceptions occur freely in the more advanced forms), 
7 running to costa or apex or rarely (probably by reversion) to termen; in the hindwings veins 3 and 4 
are usually connate, 6 and 7 generally closely approximated or stalked, and the cubital pecten is more 
often present. The group is well developed in all main regions, but absent from New Zealand. The larvae 
are normally leaf-feeders.
