556 RHODOSOMA; MACROGLO SSUM. By Dr. A. Seitz. 
with more dark yellow hindwings, whereas another southern form, angulifasda Clk. exhibits lighter, somewhat 
transparent hindwings with a narrower marginal band. - Larva variegated, with vioiettish-brown lateral and 
oblique stripes; the latter meet on the dorsum, cutting out green or yellow saddle-spots. On species of Vitis 
(Vitis inconstans, lanata, heterophylla). — The imagines are rare; they fly with a buzzing sound and, on being 
disturbed, they hold the broad abdomen bent upwards. Neither Mell nor myself found them on blossoms, 
but Mell presumes them to fly in the daytime. 
61. Genus: Ifliorfosonia Btr. 
Almost exactly like Macroglossum , abdomen flat, broad, laterally fringed, with extendible hair-tufts' 
Margins of wings smooth; abdomen variegatedly spotted. 
Rh. triopus Ww. (64 e). Dark brown, abdomen in the centre with red lateral spots, at the end with yellow 
ones. Forewing with a very large, white, somewhat quadrangular central spot; hindwing with white spots at 
the costal margin and inner margin. Larva green, behind the head thin, but then on the 4th ring thickened, 
the anal joint with the horn very much enlarged and extended, so that the large, rough tail-horn is not turned 
hindward as in the other Sphingidae, but forward over the dorsum. On the Rubiacea Adina globiflora. Pupa shaped 
like that of Macroglossum, but a little clumsier. The imagines swarm in the sunshine on blossoms, preferring 
Rarleria cristata L. in South China. They swarm more steadily, not so jerkingly, as Macroglossum , and without 
buzzing. From the Himalaya to South China in the north and Assam in the south, in some places not rare. 
It is difficult to breed the larvae. 
62. Genus: Macroglossum Scop. 
This very characteristic genus which is represented in Europe only by 1 species, in the whole palae- 
arctic region only by six, is chiefly tropical, and about 60 species are confined to tropical Asia and Africa. 
Nevertheless there are in the real tropics hardly any places where we notice such great swarms of Macroglos¬ 
sum as in the subtropical parts of China, probably because they are not so conspicuous there among the swarms 
of other insects flying around the bushes, such as the Hesperidae and Lycaenidae. In the town of Kauloong 
(Kwang-Tung) I could often count as many as 20 and more specimens which, intermixed with single Cephonodes, 
were drinking from the blossoms of Lantana-shrubs in front of me. They belonged to 4 or 5 species which were 
altogether absent during a great part of the year and suddenly occurred in enormous numbers in October. — 
The shape of all the species is very uniform and so unmistakable that it is unnecessary to characterize the 
genus here; we refer to the short characterisation by Jordan in Vol. II, p. 252, and by Hering in Vol. XIV, 
p. 378. — In America genuine Macroglossum do not occur; they are replaced there by Eupyrrhoglossum and 
Sesia. 
M. stellatarum L. (Vol. II, pi. 40 f). This lepidopteron occurring throughout the temperate palaearctic 
region has a very remarkable range since it is apparently only in Baluchistan that it wanders directly from 
the palaearctic part of Afghanistan into the Indian region. Save this single occurrence near Quetta, this lepi¬ 
dopteron might almost be regarded as a landmark of the palaearctic region; for though it is still so common 
in the Atlantic islands of this region that I found it in some places of Madeira as the most common lepi¬ 
dopteron, it does not reach America any more, nor does it reach the (Indo-Australian) Linchot Is. in Eastern 
Asia, being still common in Shikok, but already absent in Okinawa. In Sze-ehwan it also reaches its southern 
frontier and it was no more found in Kwang-Tung. However, it is mentioned again in ,,South India“ and ,,Cochin- 
china“, whereas in vast, intermediate districts it must be absent again; neither in Singapore nor in Ceylon 
or the Nilghiris I have been able to discover stellatarum. If these specimens here or in Quetta should prove 
to have only been brought over from northern countries, the species could be eliminated from the Indo-Austra¬ 
lian fauna. 
M. bombylans B.sd. (= walkeri Btlr.) (Vol. II, pi. 40 f). Recognizable by the quite blackish-brown hind¬ 
wings showing orange spots only in the inner-marginal area. Near the abdominal end two silvery white trans¬ 
verse streaks at the anterior margin of the 6th segment. Forewing like that of stellatarum, body in front with 
an olive tint. In the Indo-Australian region from the Yangtse R. to the south as far as North India and As¬ 
sam; besides also in North China and Japan. — Adult larva light green, with darker longitudinal stripes and 
fine transverse lines. On the sides of the dorsum two white longitudinal stripes; horn black. On Rubia cordi- 
folia. The imagines are common in many places; single specimens occur in Hongkong, whereas in the opposite 
Kauloong it is the most common Macroglossum, particularly in the afternoon from 2 till 6 p. m. in numbers 
on the blossoms of Lantana hybrida. 
M. avicula Bsd. (= obscuripennis Btlr.) (65 e) is smaller than bombylans, the hindwing without any 
orange band or spots. Abdomen laterally bright golden ochreous. From Java and Palawan. — Very variable; 
Huwe presumes this species to be a form of bombylans. 
M. regulus Bsd. (= fervens Btlr.) (65 e) is quite similar to avicula, but the hindwing is cinnamon-red. 
towards the margin darker; forewing with a broad dark median transverse band. South India, Ceylon.
