of tripartita, the distal border more reddish brown in the +, and more blackish brown in the 9- — Distri¬ 
buted from Ceylon to North-West India and Burma; on the wing from spring until autumn. Nearly related 
to the African rectilinea Bdv. 
A. bimacula Walk. (3 c). Larger than the previous species. Frontal process very long. Forewing with himamla. 
3 yellowish white spots of which the first is elongate-triangular, the second and third being band-like and 
oblique. Hindwing with 2 spots coloured like the distal border, being reddish brown in + and blackish 
brown in 9- The two proximal spots of the forewing are usually united. The fringes of the forewing are 
sometimes white (with the exception of the short proximal scales). — Distribution as in venulia, but the 
species occurs also on Java according to Snellen. The moth flies by day near the ground among low her¬ 
bage and grass. 
19. Genus: Hceafcsia Bdv. 
Closely related to Aegocera and Mimeusemia. Antennae even more strongly clavate than in Aegocera, 
with obtuse tip, as long as % of the forewing. Forewing in + obliquely truncate-rotundate at the apex and 
bearing a stridulating organ between cell and costal vein or beyond it, with which during flight and chirp¬ 
ing sound is produced (probably with the help of the mid-tarsi). This organ consists as in Aegocera tripar¬ 
tita of a transparent, transversely ribbed, elongate-reniform spot, the costal and submedian veins are incurv¬ 
ed according to the shape of the spot. Opposite the centre of this spot the costal margin is incrassate on 
the upperside, a small wart being formed, which is not the case in A. tripartita. The spines of the tarsi are 
long in + and 9; the hair on the tibiae and abdomen similar to that of Aegocera. ■ — Australia. The 
moths fly late in the afternoon shortly before dusk, and the continuous whistling-chirping sound, which 
recalls the song of small Cicadas, is rather loud. 
H. thyridion Feisth. (3d). Forewing with three white transverse macular bands. Hindwing orange thyridion. 
with dark brown costal and distal marginal band with which the dark brown discocellular spot is united. Ab¬ 
domen above orange with black spots, beneath black and white. — West Australia. 
H. fenestrata Bdv. (3 d). Forewing above only with 2 macular bands. Segment 3 of palpi shorter fenestratn. 
than in thyridion. — Victoria to New South Wales. 
H. exultans Walk (3d) Abdomen above for the greater part black. Forewing of + much narrower exultans. 
than in $, in both sexes with yellowish spots before and beyond the centre, with small yellowish dots in the 
basal and distal marginal areas, and everywhere with rather numerous small blue-white spots. Fringes of 
both wings spotted with white. — West Australia; rare in collections. 
20. Genus: Platagarista gen. nov. 
Frontal process truncate with raised ring at the apex. Antennae thin, exceedingly slightly incras¬ 
sate between middle and apex, distally not compressed but flattened beneath. Eyes naked. Palpal segments 
1 and 2 rough-hairy, 3 smooth and long in $ and 9- Tibiae smoothly scaled. Neuration of forewing as 
in Phalaenoides, but the cross-vein more deeply incurved and the lower angle of cell almost produced into 
a point, radials 2 and 3 and median 1 close together from this angle; costal margin dilated proximally. 
+ with 2 vitreous streaks in the hindwing between costal vein and cell-fold, the costal and subcostal veins 
and the cell-fold being curved backward; the cell-fold in both sexes a little below the centre of the cell, 
so that radial 2 (= vein 5) is not thrown off from the centre or in front of it, but distinctly from below 
centre. Segment 1 of hind tarsus prolonged and incrassate and bears like segment 2 on the outer side 
a carina which runs from the base to the apex, is transversely denticulate and doubtless pressed during 
flight against the transversely ribbed vitreous spots in order to produce a sound. — One Australian species. 
P. tetrapleura Meyr. (= albamedia Luc., maclevi Swinh.) (2g). Black, fore coxae and apex of telraplcura. 
abdomen orange, abdomen with narrow yellowish white belts. Forewing with a very oblique cliscal band 
composed of 6 spots (3 + 3), which are usually more or less confluent. Hindwing with a yellowish white 
band, which does not reach the subcostal and is of nearly even width throughout. — Queensland and probably 
New South Wales. 
21. Genus: Cruriopsis gen. nov. 
Recalls Cruria by its elongate wings. Antennae setiform, gradually tapering, distally compressed and 
bearing here also in the 9 bristles which are longer than the diameter of a segment. Frontal cone very 
distinct, but without raised rim. Eyes naked. Palpal segment 3 short in both sexes. Tibiae smoothly 
scaled. Subcostal 2 of t’orewing from the areole, 3, 4 and 5 stalked together, median 1 from the lower 
angle of cell close to radial 3, median 2 unusually far proximal, being farther distant from median 1 at 
the cell than at the margin; in the hindwing radial 3 and median 1 together from the lower angle of cell.
