Euhomalocera, new genus
Head with face smooth (vertex rubbed). Proboscis developed.
OceUus apparently absent. Antenna in male about 1, minutely
ciliate, flagellum strongly laterally compressed, ribbon-Uke, broad,
gradually narrowed toward extremities, scape normal, wdthout pecten.
Labial palpus rather short, curved, subascending, slender; median
segment sHghtly thickened with scales, roughish along lower edge,
terminal segment slender, smooth, acute, shorter than median. Maxillary
palpus minute, vestigial, appressed to proboscis.
Posterior tibia
with slightly raised bristly hairs in middle above, tarsus with bristly
hairs above.
Forewing lanceolate, aU veins present, lb very short-furcate at base,
2 and 3 stalked from angle, 7 and 8 stalked, stalk 1/3, 7 to costa, 11
from beyond middle of cell.
Hindwing sublanceolate, pointed, termen straight above, gently
rounded below; about 1, cilia under 1. Vein 2 from well before angle,
3 and 4 stalked from angle, 5 parallel, median discoidal obhterate, 6
and 7 long-stalked.
Male genitaUa of the type of Promalactis Meyrick; as described
under the species below.
Type species: Euhomalocera heliosema, new species.
Seemingly a near relative of Narthecoceras Meyrick from India,
which has similarly flattened and ribbon-lilce antennae. The differences
of external structiu'e are much shorter palpi, and the semiovallanceolate
hindwing with veins 3 and 4 stalked (in Narthecoceras
connate).
In addition the type species has a rather different facies
that, in fact, of a HeUodinid.
The genitalia certainly suggest a relationship either with Xyloryctidae
or with Oecophoridae.
