33. GENUs ANOMOXENA, MEYRICK 
Anomoxena, Meyrick, Trans. Ent. Soc. Lond. p. 28 (1917). — Type : A. spinigera, Meyrick. 
Characters. — Head smooth; ocelli posterior; tongue developed. Antennae 5/6, in &' simple, 
basal joint moderate, without pecten. Labial palpi long, recurved, second joint thickened with whorls 
of scales forming a series of separate acute projecting teeth beneath, terminal joint as long as second, 
slightly thickened with scales, acute. Maxillary palpi minute, filiform, appressed to tongue. Posterior 
tibiae clothed with rough projecting hairs above and beneath. Forewings with 1? furcate, 2 from angle, 
2-5 parallel, transverse vein very oblique outwards from 2 to 5, faint between 5 and 6, 6 and 7 stalked, 
7 io costa, 8 separate, approximated to 6 at base, 11 from near middle. Hindwings 3/5, narrow- 
trapezoidal, apex acute, strongly produced, termen emarginate, cilia 4; 2 remote, 3 and 4 nearly 
parallel, 4 from angle, 4 and 5 somewhat approximated, 6 and 7 approximated at base. 
Remarks. — This curious genus differs from the whole of the family in having vein 8 of the 
forewings separate from 7; in all the rest these veins are stalked or coincident. There can be no doubt 
as to homology, since all veins are present. It is equally certain that the genus belongs to this family and 
to the most specialised form of it as represented by the first two groups, since the highly characteristic 
hindwings are found in no other. Hence it follows that the genus must be supposed to have descended 
from a long line of ancestors in which the stalking of 7 and 8 was an invariable feature, and to have lost 
that structure, probably by the gradual reduction and absorption of the stalk, thus affording a proved 
instance of a modification contrary to expectation. The genus is probably derived from Aistotelia.

34. GENUS PYCNODYTIS, MEYRICK 
Pycnodytis, Meyrick, Ann. Transv. Mus. Vol. 6, p. 15 (1918). — Type: P. erebaula, Meyrick. 
Characters. — Head with appressed scales ; ocelli small, posterior; tongue developed. Antennae 
5/6, in cf simple, basal joint elongate, without pecten. Labial palpi long, recurved, second joint thickened 
with dense scales rather loosé beneath and triangulaily expanded with hairs on apical half above, 
terminal joint shorter than second, slender, acute. Maxillary palpi very short, filiform, appressed to 
tongue. Posterior tibiae clothed with rough hairs above. Forewings with 2-4 parallel, 6 and 7 out of 8, 
7 to costa, 11 from middle. Hindwings under r, narrow-trapezoidal, apex strongly produced, acute, 
termen emarginate, cilia 2; 2-5 remote, parallel, 6 and 7 approximated towards base. 
Remarks. — Allied to Avistotelia. 
Geographical distribution of species, — South Africa, Madagascar.
