I have not been able to examine the three following species and am therefore not certain about their generic 
position. 
L. alfaohmatus Kenr. (37 cl). ,,Heacl, legs, palpi, antennae, and thorax below light ochreous. Thorax alboluna- 
above and abdomen reddish blackish-grey. Forewing smoky chestnut-brown, towards the distal margin lighter 
yellowish. A distinct oblique white spot at the end of the discal cell; a slanting dark straight transverse line 
touches the outside of the white spot, and nearer to the distal margin there is a curved row of dark dots 
being indistinct towards the apex. Hindwing above smoky blackish-grey. Under surface unicoloured greyish- 
black. Expanse of wings: 30 mm.“ Madagascar. 
L. albosparsatus Kenr. (37 d). ,,Head, legs, antennae, palpi, and thorax dark brown. Abdomen albosparsa 
dark brown, somewhat coppery. Fore wing dark brown, towards the distal margin light ochreous, at the hind- 
margin some spots of white scales; a curved basal, median, and postmedian dark line. Hindwing ochreous 
with darker nebulous spots and with an indistinct dark transverse line. Expanse of wings; 30 mm.“ Mada¬ 
gascar. 
L. vulpicolor Kenr. (37 cl). ,,Head, palpi, legs, antennae, thorax, and abdomen fox-coloured. Forewing vulpicolor. 
fox-coloured, at the end of the discal cell with a black, white-centred spot; a dark very oblique postmedian 
line is accompanied near the distal margin by a line of small black lunae which are distally convex. Hinclwing 
monotonously red-brown. Under surface red-brown; in both wings with a very indistinct median line. Expanse 
of wings: 32 mm.“ Madagascar. 
12. Genus: Oelianella gen.nov. 
Butler, in 1882, described as Ochci hova a Lasiocampida from Madagascar, which however has nothing- 
in common with the South American genus Ochci Walk. After having vainly tried to range the species in one 
of the genera already known, I have been compelled to erect a new genus for it. It may be, nevertheless, 
that it belongs as a 1 to some species of Napta. 
Palpi densely haired, projecting a little beyond the frons. Eyes hairy. Forewing short and broad, at 
the apex moderately rounded; veins 4 and 5 almost from the same place, 6 and 7 forked, 8 from the apex of 
the discal cell or from the stalk of 6 and 7, 9 and 10 longer than their stalk, 9 into the apex. Hindwing 
with an almost straight costal margin and curved distal margin; veins 4 and 5 from the posterior angle of the 
discal cell; basal cell large, but only closed by a very short cross-vein (as in Napta), and with an accessory 
vein. Separated from Anchiritra by the shape of the forewing and the basal cell of the hindwing, from Napta 
by the short forewing and the veins 4 and 5 not being forked. 
0. hova Butl. (37 e). <$. The very peculiar marking is to be seen from the figure. Hinclwing above hova. 
dark brown. Wings beneath brown with a curved dark median band of the hindwing. $ unknown. Madagascar. 
13. Genus: ISTapta Guenee. 
Palpi of G short, not projecting beyond the frons, in the $ somewhat prolonged. Eyes distinctly hairy. 
Hind tibiae only with terminal spurs. Hind tarsi with appressed scales. Fore wing oblong with a rounded anal 
angle, in the <$ narrower and more tapering than in the?; veins 4 and 5 almost from the same place, 6 and 7 forked, 
8 from the stalk of 6 and 7, 9 and 10 longer than their stalk, 9 into the apex. Hindwing relatively short with 
a bent or almost straight costal margin and a bent distal margin; veins 4 and 5 forked; terminal vein of the 
discal cell often very fine or indistinct; vein 7 in the two first species almost from the centre between 
the base and vein 6; basal cell closed by a short, often very short cross-vein. Abdomen of <$ coniform with a 
long-haired apex. Stages unknown. 
N. serratilinea Gn. Much smaller than the ?, only 32 mm. Forewing above red-brown with serratiline 
, three blackish transverse lines; the first only angular in the discal cell, the second angular near the costal margin 
and then oblique and almost straight as far as the hind-margin, the third parallel with the distal margin and 
sharply serrate-dentate; a small discal dot. Hindwing almost black, at the costal margin rust-coloured, and 
at the hind-margin broad yellowish ochreous. Fringes very short, yellowish. Wings beneath blackish, coated 
with brownish, and with a joint darker transverse line; forewing with a large yellowish anal-marginal spot. 
— The ? has an expanse of 45 mm. Forewing bright ochreous, powdered with rust-colour, at the distal margin 
more bent than in the but with the same transverse lines. Hindwing lighter yellow, without the rust-brown 
powdering, in the centre with an almost straight brown transverse line. Madagascar. 
N. solida Saalm. (?) (37 e). Size and shape of wings very similar to serratilinea. Palpi whitish solida. 
except the apex. Head, antennae, collar, and abdomen reddish-grey; dorsum and legs red-brown. Forewing 
above brownish-red with a yellow spot at the end of the discal cell in area 5, a similar double spot in 1 b 
and 2 and yellow scaled spots on the outside of the submarginal line (particularly in area 5); the three usual 
transverse lines are brown or blackish, but hardly noticeable. Hindwing above reddish-grey, at the costal
