LYMANTRIA. By Dr. E. Strand. 
osemponis. L. kosemponis Strand (47 a). A : forewing grey, in the median area the darkest, with black markings: a 
subbasal transverse band distinctly prominent only on the costal margin and in the middle, an antemedian 
transverse line directed vertically on the posterior margin, forming in the middle an obtuse angle which is open 
towards the base, and being cut in the middle of the dorsal area by a sharply marked, black, characteristic 
longitudinal streak; the discocellular spot is a jet-black, oblique longitudinal streak; in the cell a black spot 
and a lighter one; in the marginal area three dark, almost parallel transverse lines composed of crescents and 
in some places forming wedge-shaped spots; the marginal line dotted black. Beneath grey, uni-coloured, only 
with a discocellular spot. Hindwing above and beneath uni-coloured grey; body grey or greyish-blackish. 
Expanse of wings: 30, length of forewings: 15*4 mm. — $ larger: expanse of wings: 55, length of forewings: 
38 mm. Ground-colour of forewings greyish-whitish with very scanty black markings, the characteristic longi¬ 
tudinal streak in the dorsal area of the A being absent; liindwings darker grey than in the A with fringes spotted 
lighter and darker. Kosempo, Formosa, in October. Types in the German Entomolog. Museum in Berlin- 
Dahlem. 
melanopo- L. melanopogon Strand (47 a). A'- resembles Dasychira pseudahietis and abietis. — Forewing black 
g° n - w ith a light grey subbasal area 2% mm distant from the base, and indistinctly lighter bands in the marginal 
area. Median area as broad as the subbasal area and gradually passing over into the somewhat lighter basal 
area which encloses a lighter zigzag transverse band. Hind wing above and both wings beneath greyish-brown. 
Head and dorsum of thorax black, abdomen as well as sides and underside of thorax greyish-brown. Expanse 
of wings: 36, length of forewings: 19 mm. Kosempo, Formosa, in October. Types in the German Entomolog. 
Museum in Berlin-Dahlem. 
umbrifera. L. umbrifera Wilem. A'- head, thorax and abdomen grey, the latter with reddish lateral hairs. Forewing 
grey, at the base and in the median third dark with blackish transverse lines, the subbasal line of which does 
not reach the posterior margin; the antemedian line is undulate and widened in front, the postmedian line 
thinner and opposite the cell-end dentate, the submarginal line indented, in and at the end of the cell a black 
spot, border spotted black. Hindwing dark, particularly in the marginal area. Under surface dark, hued rosy 
reddish, forewing in the middle blackish, hindwing with a black moon-spot at the cell-end, and traces of 2 curved 
transverse lines. Expanse of wings: 44 mm. Formosa. 
nebulosa. L. nebulosa Wilem. A'- forewing light grey, in the apical two thirds hued darker, the subbasal line 
black and not reaching the posterior margin, the antemedian line black, dentate, a little oblique and connected 
by a shade with the blackish discoidal spot, behind the latter a short black streak; a postmedian, slightly curved 
line is whitish, partly margined with black. Fringes spotted black. Hindwing dark, especially in the marginal 
area, with lighter fringes. $: forewing whitish, at the costal and dorsal margins somewhat brownish, marked 
similarly as in the A- Hindwing whitish, shaded darker, the darkest in the marginal area. Expanse of wings: 
A 43, $ 54 to 64 mm. Allied with L. fumida Btlr. Formosa; in April, May, August. — The A of April has 
less distinctly shaded forewings, the transverse lines are very faint, and the marginal area is hued blackish 
aprilis. (fa. aprilis form. nov.). 
xylina. L. xylina Swinh. (40 f). A'- antennae black. Palpi brown, inside white. Head, body and wings 
creamy-white. Collar red. Forewing with a brownish-black subcostal spot near the base, a small spot at the 
middle of the costa, a reddish-brown, thin transverse band beyond the middle. Hindwing in the costal area 
hued brown, both wings with brown marginal spots between the veins. Under surface dirty white with traces 
of a transverse band, body beneath and legs red. Expanse of lyings: 54 mm. Formosa. 
strigata. L. strigata Auriv. (= strigosa Auriv.). Both sexes grey, palpi above black, forewing whitish, speckled 
black, with black transverse lines, the distal one of which is very much curved like a crescent. The submarginal 
band is angled and almost clouded; marginal spots, a discocellular streak and a streak in the middle of area 
1 b black. A'- abdomen yellowish-white, so are the wings, too, except the margin being somewhat darkened. 
Expanse of wings: 37 to 42 mm. $: abdomen above yellowish, at the end and beneath dark, liindwings yellow¬ 
ish, hued reddish at the proximal margin, and the border broad dark. Expanse of wings: 52 to 59 mm. Java. 
tagalica. L. tagalica Auriv. A and $ doe-coloured, chest, abdomen and posterior margin of head hued pink. 
Forewing greyish doe-coloured with 5 angular transverse lines, a longitudinal streak at the cell-end, and a 
similar one in area 1 b, as well as marginal dots black or dark brown. A'- hindwing dark yellowish, in the middle 
and at the proximal margin hued pink and with an indistinctly dark submarginal band. Expanse of 
wings: 34 to 40 mm. $ with yellowish liindwings everywhere hued pink, with a darker submarginal band. 
50 to 61 mm. Philippines. — This species and the preceding are characterized by the two black longitudinal 
streaks of the forewings. 
dubiosa. L. (?) dubiosa Auriv. Both sexes dark, indistinctly marked; by its habitus, colour and shape of 
wings it resembles Ocneria detrita Esp., Vol. II, t. 21c, and the terminal joint of the palpi is somewhat longer 
than in typical Lymantria- species. Forewing with one darker transverse band each before and behind the 
middle and similarly coloured sub marginal spots and discocellular spot. A hindwing whitish with a darker 
margin, that of the $ unicoloured dark. Expanse of wings: A 31 to 37 mm, £ 49 to 51 mm. Java.
