Male genitalia as described for the genus.
Material examined: Mindanao, Davao Prov., east slope of Mt.
McKinley, 5600 ft., 16.IX.1946 (CNIIM Philippine Zool. Exped.
1946-47, H. Hoogstraal), 1 6", holotype, genit. slide 5733.
A peculiar, unusually colored insect with the facies of a Tortricine.
The coloring reminds one of an Articolla species.

Type species: Coenogenes melanancalis Meyrick, 1937 (India).
The identity of this genus is somewhat dubious. Clarke's illustrations
of the type specimen show that the original description of
the neuration is not correct: neither vein 8 in the forewing nor
vein 5 in the hindAving are absent. The densely scaled, unusually
looking palpi only remain for the characterization of the genus;
and indeed they are very peculiar. There are, however, no males
of the type species at hand to support the separation of the genus
by peculiarities of the genitalia. The genitalia of the female are
not very instructive, being but httle modified.
The remarkable palpi may be redescribed as follows. Basal
segment moderate, elongate and porrect. Median segment strongly
dilated anteriorly, triangular, slightly ascending, with rather closely
appressed scales along the whole edge, smoothly appressed along
the upper edge, upper and lower angles rounded; terminal segment
very small, entirely concealed, the whole palpus compressed laterally,
but less compressed along its upper edge. Forehead with a dense,
thickened, and appressed tuft, projecting in a slender, separate, and
darkly colored pencil above middle of face.
On the strength of the remarkable palpi, I attribute the following
species, represented by a single male specimen, to the present genus.
I trust that the genital characters of the male of C. melanancalis,
still to be discovered, will prove the correctness of this step.
