of specimens with facies and male genitalia placing them in the sequence just
discussed do not fit precisely with any of the species. The facies is more of
the fuscomarginata type in the first three, but with a more vinous and
Slides 10695 (Fig 320), 17916. A series from coastal and heath forest and
possibly lowland dipterocarp forest in Brunei and from the Mulu survey. This may
also be the species referred to fuscosa by Kobes with genitalia
illustrated in his fig 408. The genitalia are close to those of fuscosa
but with a larger group of somewhat shorter, more robust cornuti with broader
bases. The genitalia match those of X.
Roepke (Sumatra) in this, but the facies of sibolgae is a more uniform
brick red as in fuscomarginata.
Slide 10696 (Fig 322). A single specimen from dipterocarp forest (150m) at the
foot of G. Mulu. The genitalia are again similar to those of fuscosa but
the cornuti are longer and more slender. The genitalia illustrated by Kobes for
dohora in his fig 386 look comparable.
Slide 17860 (Fig 321). Two rather large, robust specimens, one missing its
abdomen, from 30-60m in lowland forest at Labi in Brunei. The vesica is large,
with three robust spines aligned in a dorsal position.
Slide 17911 (Fig 324). A specimen from the coast of Brunei at Seria with facies
tending more towards that of dohora but with a diffuse rufous band in the
centre of the zone just distal to the postmedial. The vesica is more as in
