C. bilineata Wkr. (Vol. II, pi. 37 c). The Chinese bean-sphinx or ,,Duchung“, is smaller than the bilineata 
preceding species ( deucalion ), the apex of the forewing is not produced, and both the middle and hind tibiae 
are here white above, whereas in undulosa the middle tibiae are brown above. For further particulars cf. Vol. II. 
p. 239. From North India across South China to North China and Japan. — North-Chinese specimens are 
said to be smaller, the body and forewings of a more yellow and olive tint (= tsingtauica Mell). Larva green. tPivjlanha 
separated from the preceding species by the horn being short though well developed until the pupation and 
by the much more distinct lateral oblique stripes. On Milettia, Pueraria, Mucuna, and presumably other 
Papilionaceae. The larvae are in some places very common, particularly in the Chinese bean-fields, where 
they are not only devoured in large numbers by crows, magpies and small beasts of prey, but also collected 
by children. The larvae are speared on to thin wooden sticks, tilted over, so that the interior of the body is 
turned outside, then washed off and baked in oil (Klapiieck). 
C. prattl J. & T . is very near to bilineata, but distinguished by the more distinct greyish-white, pink- pratti. 
tinged triangular spot at the costa of the forewing, and the hindwing being uniformly dull ochreous save 
the darker shaded base, whilst in bilineata the greatest part of the hindwing is chocolate brown. Described 
from a just emerged male from Central Ceram. — The larva was green, granulated, with 5 lateral stripes along 
the whole body. 
C. titan R.&J. (= cervina Wkr., phalaris Btlr. nec Cr., gigantea Rothsch. p. p.) (66 c) was formerly titan. 
regarded as a gigantic plialaris, but it has not so pointed forewings. In the colouring it is rather similar to 
stenosema (66 c), but the hindwing is more uniformly dark brown, not black, at the margin a little lighter. The 
shape of the wings is most similar to that of bilineata. It is the largest species, having an expanse of up to 
17 cm; Sikkim, and Khasia Hills in Assam. euroa R. & J . is perhaps a distinct species, but it at any rate cur on. 
represents titan in Timor from where this form originates. It differs from titan in its smaller size, the head 
being black in front, and the transverse bands on the wings beneath being almost obsolete. 
C. hawked <£• T. is the smallest species with an expanse of less than 60 mm, thus only about as hawi-cri. 
large as the following species Leueophlebia emittens (62 c). This species being unknown to me is reported to 
be also in other respects dissimilar to the other Clanis. Apex of forewing not pointed, margin somewhat rounded. 
Forewing van Dyke brown, with darker bands, in the disc and basal area suffused with whitish-grey. The 
interior transverse lines are proximad bordered with greyish white, a third line across the origin of vein 3 is 
widened in cell 2; of two more postdiscal lines the proximal one is distinct, the distal one indistinct. Hind¬ 
wing dull red-brown with a greyish-brown, anteriorly darker marginal band. Described from 1 from Indo- 
China. 
21. Genus: lrfeueo|»lilel>ii& Wkr. 
As to the genus we refer to Vol. II, p. 239, and Vol. XIV, p. 364. Owing to the rosy red forewing which 
is parted by a yellow, branched longitudinal ray, the insects are not to be mistaken for any other genus. The 
genus is more at home in Africa and in the palaearctic region. The larva live on Gramineae, which food is 
quite uncommon with Sphingidae. 
L. lineata Ww. (= luxeri Bsd., rosacea Btlr.) (Vol. II, pi. 37 c) is the largest and finest species of the Uneata. 
genus. The yellow central ray on the fore wing is shaded with brownish. From Shantung across China and 
India to Celebes, and from Ceylon to the Philippines. To what has been said in Vol. II (p. 240) we may add 
that the proboscis is stunted and cannot be used by the insect, for which reason the imagines are not to be captured 
on blossoms but on the lantern. — Larva green with a rosy red head and horn and a thick white longitudinal 
lateral stripe, without distinct oblique stripes. The shape and habitus is somewhat similar to that of a larva 
of Macroglossum stellatarum. On sugar-cane, presumably also on other Gramineae. It grows very slowly and. 
before the pupation, it lies motionless for a long time in a curved position, before it changes into the smooth 
yellow pupa. 
L. emittens Wkr. (= bicolor Btlr., clamascena Btlr.) (62 c) has been dealt with already in Vol. II. p. 240; emittens. 
but as it occurs in the whole of India as far as Burmah, we have figured it here. 
22. Genus: Polyptychus Hbn. 
Of the approximately 50 species of this genus only 2 or 3 occur in the Indian region, all the others are 
Ethiopian and have been dealt with in Vol. XIV, p. 364—369. In Vol. II, where the genus has been characterized 
(p. 240) we had already pointed out that the 3 only Asiatic species two of which penetrate also into the palaearctic 
region, will probably have to be separated later on as a separate genus. 
P. trilineatus Mr. (= dentatus Hmps.) (Vol. II, pi. 37 c). In Vol. II the North-Indian form undafiis trilineatus. 
R. ds J. has been figured (as -trilineatus), occurring in North-West India on the palaearctic frontier. It is almost nndatus. 
exactly like the type, whereas luteatus R. & J., from Ceylon, is much lighter, either red, darkened ochreous, lutealus.
