Hypopygium; ventral lobe and outer lamella are seen. long, band-shaped, the apical half somewhat .spoon-like dilated with an oblique apical margin; they are whitish yellow, the apical dilata- tion with a blackish brown margin; the dorsal margin bears mod- erately long hairs; the apical margin has curious, very long, flattened, somewhat curved, brownish or blackish hairs; the first hair on the ventral side is specially broad, almost lancet-shaped; in the middle of the ventral margin is a single, strong hair; the outer lamellae are shorter than in the preceding species, not reaching beyond the end of the hypopygium, they are whitish yellow with the apex black; the apical margin is roundly incised, the dorsal corner prolonged into, or bearing a long, thin, styliform tooth, the ventral corner drawn out into a short, broad tooth, near which is a curved spine on the inside; the dorsal margin has short, the ventral margin long hairs. Legs long, front tarsi long and thin, metatarsus longer than tibia, the whole tarsus much more than twice as long; the last joint compressed, a little dilated; middle tarsi considerably longer than tibiae, hind tarsi as long as tibiae, the metatarsus a little shorter than the second joint. The legs are yellow, posterior coxae grey with the apex yellow, hind coxae often more yellow, only with a grey spot on the outside; anterior tarsi with the very apex of metatarsus, and the four following joints blackish, the last joint of the front tarsi silvery on the anterior side; hind tibiae very slightly brownish towards the end, hind tarsi blackish.
