28 LEPIDOPTERA HETEROCERA 
with projecting hairs on apical third, terminal joint concealed. Forewings with 2 separate, 7 and 8 
stalked, connate with 6 from apex of cell, 7 to apex, ro from 1/2, 11 from 2/5. Hindwings over 1 (?), 
trapezoidal, apex pointed, termen sinuate, cilia very long (assumed 3-5 separate, 6 and 7 stalked). 
Remarks. — Not known to me, and the characters are incompletely given by the author, who 
apparently considers the genus allied to Chilofselaphus, which is doubtful; perhaps belonging to prece- 
ding group. 
Geographical distribution of species. — 5. W. Europe. 
Larva unknown.

16. GENUS TRICHEMBOLA, MEYRICK 
Trichembola, Meyrick, Exot. Microlep. Vol. 2, p. 115 (1918). — Type : T. segnis, Meyrick. 
Characters. — Head smooth-scaled; ocelli very small, posterior; tongue short, Antennae 5/6, 
in gf shortly ciliated, basal joint elongate, without pecten. Labial palpi with second joint extremely 
long, straight, porrected, loosely scaled beneath, above with long rough projecting hairscales diminishing 
to apex, terminal joint short, obliquely projecting. slender, pointed. Maxillary palpi rudimentary. 
Posterior tibiae clothed with long hairs above. Forewings with r5 furcate, 2-6 remote, 7 and 8 stalked, 
7 to costa, 9 sometimes absent, 11 from middle. Hindwings r, narrow-trapezoidal, apex pointed, termen 
more or less emarginate, cilia nearly 2; 2-5 remote, parallel, 6 and 7 rather approximated at base, 
Remarks. — Probably related to Megacraspedus. The absence of vein 9 is a specific character 
only.
