190 (lYROTHRIPA. By M. Gaede. 
R. lunata Mschlr. (18 c). Body yellowish brown. Forewing dark brown and olive brown. A faded 
white hne below the costal margin. The exterior part of the median area as far as vein 3 whitish. Interior 
line black, obliqiie at the costal margin, extra-angular in and below the cell, introangular at the median vein 
and vein 1. Reniform macula edged with black, angled. Veins 7—5 with black streaks as far as the exterior 
line which is black, oblique, dentate. Sidjinarginal line blackish brown, finely dentate below the costal margin, 
between vein 8 and the discal fold, strongly incurved, strong, inwards below vein 3. Hindwing white, margin 
broadly brown. 30—33 mm. West Africa. 
R. diplogramma Ihiips. (18 c) and the following species are rather divergent. Body and forewing 
greyish brown, whiter in the median area. Whitish at the inner margin at tlie base, edged with black above. 
Interior line double, black, strongly extra-angular in the submedian fold, then ending near the basal spot. 
A black dot in the middle of the cell. Reniform macula round, finely edged with black. Exterior line fine 
blackish, bent inwards from vein 4, strongly notched. Black streaks behind it at the costal margin. Hind¬ 
wing white, diaphanous, margin broadly smoky brown. ^ 28 mm. Bechnana Land. East Africa. We figure 
a specimen from Tabora. 
R. sticticraspis Hrnps. (18 c). Similar to diplogramma . Forewing with a longer v.diite basal spot. The 
white median band extends only to the lower cell-edge. Interior line as a black streak at the inner margin. 
Reniform macida and cellular dot as in diplogramma . Median and exterior lines as a streak at the inner margin. 
A short black shadow from the apex. Hindwing as in diplogramma. Q 25 mm. East Africa. 
24. Genus: Oyrotliripa Hmps. 
Proboscis normal, ]ia]pi thick, very long porrect. Antennae of finely ciliated, abdomen with 2 small 
tufts at the base. The d' with a hair-tuft below the base of the wing. Vein 3 of forewing far before the 
angle, 5 close above the angle, 10 and 7 + 8 + 9 from the apex of the small areole. Veins 3 + 4 of hind wing- 
on a long stalk, arising with 5 from the same base. Vein 8 fused with tlie cell for a somewhat longer distance 
than in the last genera. Type: pusilla Mr. 
G. pusilla 2Ir. Body greyish brown. Forewing olive brown, the costal and distal margins violettish 
brown. Interior line indistinct, double, bent. Median line the same, slightly excurved in the middle, somewhat 
lead-cclonred before it. Exterior line double, from vein 6, somewhat undulate, inwards, lead-coloured behind 
it. Sid)marginal line whitish, edged with olive brown on both sides. Hindwing white, diaphanous, broAvn at 
the margin. 16 -20 mm. Gold Coast, besides from India to Australia. 
Subfamily Acontianae. 
This very large subfamily - about 350 forms have been descrilied - is chiefly tropical. Scarcely 8 
or 9 species occur in Europe which has relatively little sunshine, and these especially in the south-east. A 
larger number, however, is distributed over Eastern Asia, extending here from the equatorial districts to Japan 
along the coast, so that the palaearctic region is reached there as well as at the frontier of the Indian region 
by further 30 s]:)ecies. These statements indeed do not agree with the previous pubhcations, since the sub¬ 
family had formerly been quite differently grouped. Owing to the confusing interpretation of the nomen- 
clatural rules, the Acontia were meant to be the Tarache of to-day, and the genus named now Acontia was 
formerly called Xanthodes Gn. Thus the former Acontianae'’ became the “Erastrianae" dealt with on p. ill 
to 166. It is also hardly to be recognized to-day in what way they were composed nomenclatnrally, since the 
generally known generic name of Thalpochares is merged in other genera {Eiihlernma, p. 113). In this Ave fol¬ 
low exactly Hampson's classical work, without enlarging on the different redenominations in his “Catalogue’'. 
Very little is known of the life-history of the Accniianae, if we take no account of the six species reach¬ 
ing Central Eurojje. The larvae have 16 feet, yet single species are said not to use the front pair of abdominal 
legs in their locomotion (as in the Plusia. Gonospileia and others), so that they move on somewhat like the 
Geometrids do. In spite of their frequently bright colouring, most of the lepidoptera seem to fly exclusively 
during the night, and sometimes the Acontia are the first in the evening to come to the lanterns. Many are 
unicoloured when at rest, with their hindwings covered, either green like most of the Earias, Hylophila and 
others, or also with a silvery gloss like the Plusiocalpe and some (Indian) Westermannia ■, a very uncommon 
impression is also made by the Indo-Papuan Vizaga with unicoloured blue hindwings. Of a strange colouring 
is also the cpiite unicoloured blackish-brown Hypodeva superha, with a faint violet reflection in the distal part 
of the hindwing, Amry unlike its proud name. The remark that the larAme construct a canoe-shaped case 
for then- pupation can hardly be generalized owing to the fact that there is only a small number of species, 
the early stages of Avhich are knoAvn. 
Proboscis almost invariably normally developed. Palpi long, mostly erect. Eyes round, Avithout hair 
and cilia. Antennae mostly ciliated, rarely pectinated. Thorax A\ith small tufts or Avithout any at all. Tibiae
