species: propitia Guérin-Méneville.
(type species ochracea Swinhoe,
India = lutea Walker).
facies is generally yellow, with strong, straight submarginal fasciae that are
contiguous across the wings on each side and provide a base for an irregular
darker shaded sector to the marginal area. Darker markings basal to the
submarginals tend to be small, punctate or non-linear. The forewings are
slightly falcate apically. The male antennae are fasciculate.
abdomen has a massive corematous structure within a broad ring on the eighth
sternite that contains a flocculent mass of hairs. The tergite also has a slight
distal corema within a transversely oval ring of sclerotisation that tapers
basad to join the narrowly sclerotised anterior margin. In the genitalia, the
uncus is simple; the type species has a scaphium, but not its Bornean congeners.
The valves are elongate, rounded apically, centrally thickened, with a process
arising within the valve from near the base of the costa; these processes show
minor bilateral asymmetry. The costa extends an apodeme interiorly that forms a
transtilla with its opposite number. The juxta is short, but H-shaped. The
aedeagus vesica is convolute, but none of the diverticula is particularly long.
female genitalia of the type species have the ostium within the seventh segment,
flanked on each side by small pouches that contain numerous short hairs. The
ductus is relatively short, the bursa an elongate pyriform with a basal bulge
that gives rise to a slightly helical ductus seminalis. There is coarse
scobination at the opening to this, and general rugosity elsewhere in the bursa.
The ovipositor lobes are narrow, acute, with a longitudinal strip of darker
sclerotisation as in the Catocalini (p. 38) and Catephiini (p. 84).
biology of the type species is described below. The pupa has a bloom.
genus is predominantly Oriental, with one species in Africa (Poole, 1989), but
the placement of some of the species needs checking. Poole included as a valid
species a taxon H.
from Java. The original description by Snellen is of a female, flagged by
‘(Brit. Mus.)’ and not as a new species as elsewhere in the same
publication. The illustration suggests that the reference may merely be to Tochara
(see previous genus).
