Group 8 (Lecithocera type) 
An extensive group with much generic development, of which the most noticeable prevailing 
character is the length of the antennae, which are commonly as long as or longer than the forewings, 
but this is not constant, and in some genera (especially but not exclusively the more primitive), which 
cannot be advantageously separated, they are no longer than normal; there is also a not infrequent 
tendency to long antennal ciliations in the c, or sometimes to thickening of the stalk, in those forms in 
which the antennae are not especially long. The palpi are usually long and simple in structure, rarely 
tufted, but sometimes curiously modified in the c. In the forewings the termination of vein 7 may be 
costal, apical, or terminal, the last-named being the original type; 2 and 3 are usually stalked, but 
sometimes even very widely remote in the more advanced forms. The hindwings generally show little 
or no terminal sinuation; veins 3 and 4 are usually connate, stalked, or coincident, 6 and 7 connate or 
more generally stalked; the cubital pecten is always absent. The group is especially characteristic of the 
Indo-Malayan region, where it forms a very prominent feature; a certain number of forms derived from 
this fauna are found in Africa, Australia and the Palaearctic region; from America the group is almost 
wholly absent, and it is also not found in New Zealand. The larvae sometimes feed on leaves, but also 
often on dead or dry vegetable substances, which was the primitive habit of the family.

Oecia, Walsingham, Proc. Zool. Soc. Lond. p. 111 (1897). — Type : O. oecophila, Staudinger. 
Macroceras, Staudinger, Stett. Ent. Zeit. Vol. 37, p. 150 (1876) (praeocc. -a, -os, -us). — 
Type : O. oecophila, Staudinger. 
Characters. — Head with appressed scales; ocelli posterior; tongue absent. Antennae over r, 
in cf stout, simple, basal joint moderate, without pecten. Labial palpi long, rather curved, diverging, 
second joint thickened with dense scales, terminal joint nearly as long as second, moderate, pointed. 
Maxillary palpi very short. Posterior tibiae and basal joint of tarsi with long loose hairs. Forewings 
with r$ furcate, 2 from 4/5, 7 and 8 stalked, 7 to costa, 11 from middle. Hindwings hardly r, ovate- 
lanceolate, cilia 2; 3 and 4 remote, 5 somewhat approximated, 6 and 7 long-stalked. 
Remarks. — À peculiarly modified form, which has puzzled authors, but can only be regarded 
as a member of this group, with some affinity to Symmoca.
