blacker and more heavily marked. Ground colour is more brown than yellow and the pale veins stand in 
sharp relief, especially in posterior area. Also the black colouration of hindwings is deeper and more exten¬ 
sive. Underside is also darker and all markings are heavier. In South China subsp. roseata Mell, f. palles- 
cens Mell and /. acuta Mali also occur; in regard to these compare Vol. 10, p. 536. 
10. Genus: In eucoplilebia Ww. 
L. lineata Ww. (Vol. 2, p. 240, pi. 37 c). —- Ova pale green, roundish. — Special characteristics 
of the larva are its sleekness, the different colouration of the head to the rest of the body and the only 
markings which consist of a subdorsal line. Horn carmine red to pale red-brown, tip straightly truncate. 
The larva feeds up very slowly just as Clanis, taking 70 to 80 days ! It eats very little quantitatively. Hiber¬ 
nation takes place m the larval stage. Also in summer specimens the prae-pupal stages take on an average 
double as long as the pupal stage. Just as in Clanis larvae it retains its prae-pupal capacity to crawl away. 
Pupa roundish, smooth, the skin is thin and dull brown and it wriggles actively. Cremaster situate slightly 
dorsally, it is short and pointed (slight traces of bifurcation). 
11. Genus: Polyptyclms Hbn. 
I he food plants of both species, so far known to occur on palaearctic territory are tree-like Boragi- 
naceae (which is quite exceptional as a food plant for Sphingidae). Young larvae have black bifurcated head- 
horn, which later on changes to green; after the last (5th) moult it is discarded, the head becomes roundish 
and tapers off towards the top. Horn bold, 10—13 mm long and roughly granulose. The larvae are generally 
in pairs on a bush, the ova appear to be deposited in pairs. On being disturbed the full grown larvae react 
in a curious way, the first 3 segments are rolled back ventrallv. Pupae glossy red-brown, constricted on 
metathorax; cremaster wider than thick, edge rough and glossy black, tip widely bifurcated. Formerly only 
one specimen each of trilineatus and dentatus was known from China. Mell has discovered both species 
in the south of China. Compare Vol. 10, p. 537 — 538. 
P. trilineatus Mr. (\ ol. 2, p. 240). Ova roundish oval, watery green, very transparent. The young 
larva has at the commencement its own particular peculiarity, as the first moult takes place before it has 
eaten any leaf food, a recently hatched larva devours a part of its egg shell and then rests immovable on 
a rib of a leaf nearby, awaiting the first moult. Besides from the first to the third moult it has an unusually 
well developed head horn with distinct bifurcation, giving the general impression of a tail at each end 
Ihe larval stage usually takes abt. 4 weeks. Also this species hibernates as larva in a prae-pupal state. — 
It may be assumed that the metamorphosis of dentatus Cr. (Vol. 10, pi. 66 a) is similar. The southern Chi¬ 
nese form of trilineatus is subsp. tr. costalis Mali (Vol. 10, p. 538). Besides there are several subspecies oc¬ 
curring in the tropics. 
P. draconis R. & J. (12 d). A species described in 1916 from Thibet, of which only a few specimens 
are known. Probably the largest Polytychus so far discovered; expanse of forewings of $ 57 mm, of $ 66 mm. 
Similar to trilineatus , but ground colour more ashy grey, mixed with blackish and without the brownish tone. 
Margins of wings more dentate. Apex of forewings more extended. Distribution of transverse lines on forewings 
like in trilineatus. Both discal lines more regularly curved inwards from costal to hind margin, the outer 
one more distinctly bordered with grey and not bending outwards. The cloudy subapical spot ends at ra- 
dialis 3. Hindwings paler especially at costal margin. On underside of forewings the outer blackish line very 
faintly indicated (almost extinct in $) and edged outwardly by a distinct grey-white line. The inner discal 
line is extinct. The inner discal line on underside of hindwings is more heavily marked, the outer one almost 
extinct, the entire outer marginal area is very dark and contrasts sharply from the inner area of wings, as 
it is also edged on its inner border by a grey-white line. Genitalia are entirely different to those of trili¬ 
neatus and dentatus. Ihe 10th tergite ends in a wide, blunt hook; the sternite is a large shield, which is con- 
\ex on the upperside and incurved apically, the two lobes separated by this intersection are widely round and 
slightly bent downwards. The valve is much larger than in trilineatus and outwardly intersected. (Inspite of 
the plate number indicated, this species was not illustrated in Vol. 10.) 
12. Genus: Maruniba Mr. 
M. gaschkewitschi complacens Wkr. (12 d and Vol. 2, p. 241). — Ova elliptical, the bright pale green 
of a fiesh leaf. Pupa dark brown and coarse-grained; cremaster with 2 closely approximate points. —- 
subsp. irata J. & K. (12 e) from fhibet, is denominated as a species by ,/. <0 K., it is however a subspecies 
of gaschkewitschi , which can readily be differentiated from g. complacens , to which it is most closely related. 
Firstly the fringes of both wings are distinctly white in the interstices between the veins; the 2 outer of 
the 4 antemedian lines are heavily curved and are parallel to one another, the space between the ante and
