on veins. Forewing underside fumous brown-grey, margins with weak whitish grey irroration, traces of stigmata present but diffuse, cilia chequered with whitish. Underside of hindwing whitish grey, densely irrorated with dark grey and brown scales; costal margin and veins covered with brown. Transverse line diffuse, dark grey, discal spot sharply marked, lunulate, defined with whitish. Cilia pale grey, chequered with whitish. Female. Similar to male, antenna filiform, median fascia strong, oblique, blackish, hindwing with stronger dark irroration. The holotype of areolona differs only slightly from the other specimens of the species by its more uniformly greyish ground colour of the (brewings with more expressed, longer whitish streak below cell and the less strong, more obsolescent subterminal line. The genitalia of both sexes are characterized in the description of the genus (Figs 13-14). Bionomics - The species is known from medium-high and high altitudes in North Yuennan, inhabiting probably the upper parts of the forest belt and the lower parts of the subalpine regions. The imagines were collected in June. Distribution - The species is known only from the type locality, A-tun-tse (North Yuennan, China). Speidelia gen. n. (Figs 5-12, 15-21) Type species - ?Cucullia taiwana WlLEMAN, 1915, Entomologist 48: 144. Type locality: Formosa [= Taiwan]. Species included: - taiwana taiwana (WlLEMAN, 1915) - taiwana semialba (YOSHIMOTO, 1993) - apocrypha sp. n. - formosa sp. n. Diagnosis - The genus Speidelia is the allopatric sister-genus of Xylocampa GUENÉE, 1837, the outgroup of these genera is most probably the genus Atakterges. The species of Speidelia differ externally from those of Xylocampa by their narrower, more elongate forewings with reduced crosslines, longer, much more flattened orbicular stigma and less expressed, smaller subcellular extension of reniform stigma, and by their shorter, more rounded, whitish hindwings. A characteristic external feature of the genus Speidelia is the presence of strong, conical frontal prominence, while the frons is smooth, slightly convex in the species of Atakterges and Xylocampa. The main differences between the male genitalia of Speidelia and Xylocampa are as follows: - clasping apparatus of Speidelia: uncus longer, narrower; cucullus shorter, broader, less helmet-like; corona weaker; pollex-like extension without stronger
