301. GENUS CANTHONISTIS, MEYRICK 
Canthonistis, Meyrick, Zool Med. Leid. Vol. 7, p. 82 (1922). — Type: C. amfhicarpa, Meyrick. 
Characters. — Head with appressed scales; ocelli posterior; tongue developed. Antennae 
over r (?), in cf rather stout, simple, basal joint elongate, without pecten. Labial palpi very long, 
recurved, second joint with appressed scales, terminal joint as long as second, slender, pointed. 
Maxillary palpi rudimentary. Posterior tibiae with median tuft of long scales, apical half with appressed 
scales. Forewings with 15 simple. 2 from towards angle, 3 absent, 4 and 5 short-stalked, 7 absent, 8 and 
9 stalked, 11 from before middle. Hindwings r, elongate-trapezoidal-ovate, cilia 1; 3 and 4 coincident, 
5 closely approximated at base, 6 and 7 stalked. : 
Remarks. — Probably derivable from Habrogenes. 
Geographical distribution of species. — Malayan. 
Larva unknown.

302. GENUS HABROGENES, MEYRICK 
Habrogenes, Meyrick, Exot. Microlep. Vol. 2, p. 102 (1918). — Type : H. eufatris, Meyrick. 
Characters. — Head with appressed scales, sidetufts somewhat raised; ocelli very small, 
posterior; tongue developed. Antennae over r, in cf simple, basal joint elongate, without pecten. Labial 
palpi very long, recurved, second joint thickened with appressed scales, terminal joint longer than 
second. slender, acute. Maxillary palpi very short, filiform, appressed to tongue. Posterior tibiae loosely 
haired above, with rough expanded median tuft of scales. Forewings with 15 furcate. 2 and 3 long- 
stalked, 8 and 9 out of 7, 7 to apex, 11 from beyond middle. Hindwings t, trapezoidal, termen hardly 
sinuate, cilia 3/4; 3 and 4 stalked, 5 slightly approximated, 6 and 7 stalked. 
Remarks. — This and the preceding genera probably indicate a line of development collateral 
with the Timyra group. 
Geographical distribution of species. — Indo-Malayan. 
Larva unknown.
