bornescripta sp. n.
14, 15mm. The forewings are marked
dark grey on yellow as illustrated, the facies resembling B. collivolans Butler
comb. n. (Sumatra) and a group of species from Sulawesi (B. scripta Walker
comb. rev., B. celebesa Tams comb. n.) and the Moluccas (B.
sanguitincta Hampson comb. n., Batjan). However, the antemedial
fascia is less strongly three-arched and does not make contact with the subbasal
or the postmedial. The striae in the area distal to the postmedial are longer,
and there are corresponding ones (but weaker) on the hindwing, only slightly
manifested in collivolans and the more easterly species. The forewing
fringes are yellow rather than dark grey. The male genitalia also indicate
affinity to the eastern species in sharing possession of two rather even, dense,
squarish arrays of short spines in the aedeagus vesica. The valve structure is
also similar, as is that of the roseororatus group. B. dohertyi Rothschild
(Lesser Sundas) is another member of the scripta group (Holloway, 1982:
