einerascens Strd. only differs in its smaller size (45 to 50 mm) and the greyish ground-colour of the Cameroon 
to Mukinbungu in the Congo District. Tessmann describes the larva, as follows: ,.The larva is of the type 
of Bonibyx neustria, brown, with whitish and reddish and grey streaks, trunk-coloured, on the dorsum more 
ashy-greyish, on the sides of the 4th, 5th, and penultimate rings deeper brownish, below it more intensely 
whitish. Hairing uniformly feeble, on the dorsum somewhat stronger hairs on each side, particularly on the 
penultimate ring above; on the head two longer hair-tufts on each side, being blackish, at the tips whitish. 
The larva is common in the plantations on cocoa and other bushes, in the primeval forest on various shrubs 
(pepper etc.); it feeds on various plants. Pupa in a soft whitish web.“ 
L. regularis Strd. (34 c). §. Similar to the $ of L. per af finis, but separated by the quite straight 
and even (not dentate) discal line. $ unknown. South Cameroon. 
L. fuscofasciata Auriv. (34 b). <$. Head and thorax light greyish-yellow; abdomen whitish. Forewing 
yellowish, at the distal margin very broad, about 6 mm, violettish-grey with a white, black-ringed discal dot 
and the usual black transverse lines. Hindwing above whitish, with a broad dark brown transverse band close 
in front of the distal margin. $ unknown. Banana on the Congo River. 
L. rufobrunnea Strd. (= punctulata Holl.) (34 c). The A of Strand’s species being figured here 
so exactly corresponds with the <$ of punctulata Holl. that their identity cannot be doubted. As the $ of rufo¬ 
brunnea Holland’s L. punctulata $ is to be regarded. Both sexes are thus distinguished by the dark dots and 
streaks on the fore wing being accompanied by white spots, whereby the species is at once discernible from 
L. peraffinis. Cameroon, Gabun, Congo District. — The form regarded by Strand as rufobrunnea -$ must, 
however, be a different species. 
L. strandi sp. n. (= rufobrunnea Strd. $) (34c). $. Easily to be recognised from the figure. A 
unknown. South Cameroon, Gabun. 
L. siccifolia Auriv. (40 b) <$. Yellowish-brown; palpi dark brown. Wings above yellowish-brown, 
with the usual transverse markings and the discal dot of a dark brown colour. Hindwing above yellowish- 
brown, at the costal margin as far as vein 5 red-brown. Forewing beneath light yellow, at the margins narrowly 
brownish. Hindwing beneath yellowish-brown with the normal markings being faded and broken up into spots. 
$ unknown. Cameroon. 
L. marginepunctata Holl. ($ = puncticosta Strd.) (34 b, c) is a very different and sharply defined 
species with grey different sexes. <$. Head, collar and thorax light fawn-coloured; abdomen, chest, and legs 
still lighter, wings light fawn-coloured with a slight grey hue. Forewing above with a silvery lunar spot at 
the end of the discal cell, whitish transverse lines being narrowly edged with dark, and a submarginal row 
of angular blackish spots; this row is distally curved in the areas 2 and 3 and continued on the hindwing. 
Expanse of wings: 35 to 37 mm. — The much larger ^ being at first sight quite different shows, as is to be seen 
from the figure, almost exactly the same marking. Abdomen above almost white. Sierra Leone to Congo. 
L. humfreyi Auriv. Unfortunately I cannot affirm with certainty, whether this species belongs to the 
first group of species. Fawn-coloured; abdomen above and the wings beneath at the base and anal margin 
lighter. Forewing above with d.ouble and indistinct subbasal and discal transverse lines; the subbasal lines 
are curved, the discal ones undulating, but not dentate; a small black dot at the cell-end; a submarginal row 
of black spots in 1 b to 8 is inwardly bent in the areas 4 and 5. Hindwing above without markings. Wings 
beneath with two indistinct undulating brown discal lines and a submarginal row of black spots, at the apex 
and distal margin strewn with grey scales. Expanse of wings: 42 mm.“ — ,,$. Larger and lighter than the 
the submarginal spots are larger and also distinct on the hindwing above. Expanse of wings: 60 mm.“ 
Gold Coast and Nigeria. The species is allied with marginepunctata, but separated by the black discal dot of 
the forewing. 
Second Group of Species. 
In the species belonging to this group the straight costal margin of the hindwing gradually passes over at vein 8, 
without forming an angle or a distinct boundary, into the straight or uniformly bent distal margin. 
L. major Holl. (34 c). The figures published here were most kindly communicated to me by Dr. W. J. 
Holland; they make it unnecessary to describe the species at large. The sexes were captured in copula. It is 
noteworthy that the large white discal dot of the A forewing is absent in the $. Ogowe. 
L. dives Auriv. (40 c). A- Body yellowish grey; palpi dark grey. Forewing above greyish-yellow, 
at the distal margin broadly grey; transverse lines blackish, double, sharply angular or dentate, the proximal 
discal line composed of distally open bows, both being angular at vein 8; discal dot black centred with 
grey; the submarginal line is composed of separate dark sj>ots. Hindwing above reddish-brown, darker than
