110. GeNus POLYHYMNO, CHAMBERS 
Polyhymno, Chambers, Canad. Ent. Vol. 6, p. 246 (1874). — Type : P. /uteostrigella, Chambers. 
Copocercia, Zeller, Hor. Soc. Ent. Ross. Vol 13, p. 374 (1877). — Type : P. crambinella, Zeller. 
Characters. — Head with appressed scales; ocelli posterior; tongue developed. Antennae 4/5, 
in gf shortly ciliated, basal joint moderately elongate, without pecten. Labial palpi long, recurved, 
second joint smooth-scaled or seldom rough at apex beneath, terminal joint as long as second or longer, 
moderate, acute. Maxillary palpi very short, filiform, appressed to tongue. Posterior tibiae clothed with 
hairs above. Forewings with apex more or less produced and subfalcate; 1? furcate, 2 from angle, 7 and 
8 very long-stalked or coincident, 7 (if present) to costa, 11 from beyond middle. Hindwings under r, 
elongate-trapezoidal, apex produced, acute, termen sinuate-emarginate, cilia 2-3; 3 and 4 connate or 
short-stalked, 5 approximated, 6 and 7 long-stalked. 
Remarks. — Structurally and superficially it would seem natural that this characteristic genus 
should be the ancestor of TAiotricha and its allies, yet the geographical distribution makes it highly 
improbable. It is likely therefore that all are alike descended from a more ancient extinct form, of which 
Polyhymno preserves the main features. 
Geographical distribution of species. — Summarised thus : African 16, American 10, 
Indian 1. This is therefore one of the comparatively few genera (as Tiquadra and Ceromitia) exhibiting 
direct faunal connection between Africa and America.
