India, Andamans, Philippines, and Sula Is. — dracomoiltis Mell is smaller, lighter, the ground-colour mor edracomoniis. 
brownish-grey, the fringe more distinctly speckled (as in nyctiphanes), the base of the hindwing more grey¬ 
haired, abdomen beneath without the small grey discal spots on the posterior rings; China. — Specimens from 
Ceram are intermediate forms between rufescens Btlr. and dracomontis Mell, and are much smaller than the 
Australian severina ; they were denominated: — joachimi Cllc. - severina Misk. is the form from Queensland joachimi. 
with intensely olive forewings, especially in the proximal halves; hindwing at the costal and anal margins severina - 
lighter, the light distal band more distinctly marked, especially at the anal angle. — Larva green, the adults 
with broad white oblique stripes in the sides, brown pectoral feet, and a very long, green, straight horn. On 
Melodorum oldhami (Anonaceae). - The species is not common and has two generations in China. 
M. hyloicoides Rothsch. (68 a). Exterior similar to that of a dark Hyl. francki (cf. fig. in Vol. VI). Head hyloicoides. 
and tegulae black, their edges and the palpi cinnamon-coloured. Thorax and patagia light yellowish-brown, 
with a broad black central edge. Abdomen dark brown with a brown median band and dark ring-margins. 
Forewing with a tan-coloured base; basal third blackish-brown, with 5 or 6 irregular, brown and grey zigzag 
transverse bands; the rest of the wing with white, brown and grey bands and spots. At the apex a mud- 
coloured costal spot. Hindwing in the interior three quarters cinnamon-brown, near the inner area indistinct 
blackish spots. Distal quarter blackish, dusted with yellowish-grev. Fringe cinnamon-red, mixed with whitish. 
$ considerably larger than the $. Dutch New Guinea. 
A few more forms of this genus have been described, being mostly based upon a single specimen. As I 
am unable to examine the forms myself, I cannot decide whether they are distinct species or whether they 
are geographical representatives of analis. One of them is subalba Clk. referring to South-Chinese specimens, subalba. 
Smaller than analis from Shanghai figured in Vol. II, pi. 36 c; distinguished particularly by the whiter under 
surface of the body. — clossi Gehlen, from Borneo, is rather larger, the upper surface lighter, particularly the clossi. 
hindwing in the anal region almost white. The forewing lacks the brown stripe which extends from the stigma 
to the inner margin before its centre. — sumatranus Clk. is a form entirely like Borneo-specimens; it represents sumatra- 
the species in Sumatra. nus ■ 
5. Genus: J^eucMtmoiiia R. & J. 
The genus contains but 1 Australian species, the size and exterior of which is about between that of 
Hyl. pinastri and that of Herse convolvuli. The proboscis is still longer than the body. The first anterior tarsal 
joint has no prolonged spines. 
L. bethia Ivy. (= distinctum Rothsch.) (60 c). Forewing quite light grey beside a very dull brown bethia. 
transverse shadow, only the central dot and the apical boundary line, which is only short in Herse , long and 
extends almost to the central dot. Hindwing blackish-brown, at the anal margin lighter. North and West 
Australia. 
6. Genus: Psilogramma R &J. 
From this genus which has been accurately described in Vol. II, p. 234, only 1 common species was 
known, the palaearctic representative of which is figured on pi. 36 b of Vol. II. Later on another species was 
found in a South-Sea island. 
Ps. menephron Cr. (= cliscistriga Wkr., abietina Bsd., darius Men.) (60 d) almost looks like an M. analis menephron. 
being one third smaller, but the white dentate line defining the basal area is more distinct, and the dent at 
the anal angle of the forewing is only marked by a slight convexity. Colouring and marking most variable. 
Very pale specimens with a grey tint have been described as ab. vates Btlr. — ahrendti Pag. are specimens vates. 
from Amboina; the type considerably excels even the casuarinae; it has an expanse of 120 mm. Forewing almost ahrendti. 
unicoloured dark ashy grey with a white central dot; hindwing with bright bands, abdomen on ring 2 with 
an uninterrupted white posterior edge, whilst on the rings 3—6 it is interrupted; fringe speckled as in casuarinae, 
though this form is just as little geographically definable as macromera Btlr. for Borneo-specimens and melano- 
mera Btlr. for North India. — nebulosa Btlr., from Australia and the Papuan Is., already form a transition 
to the Australian casuarinae Wkr. (60 d), the rather bright ground of the wing shows a large blackish-brown casuarinae. 
costal-marginal spot in the median area, in which the bright white central dot is situate, which is not so distinctly 
prominent in typical menephron. — It may be that the Australian form turns out to be a distinct species, like 
increta which has been dealt with in Vol. I as a form of menephron and which occurs together with typical 
menephron, but has a different larva and pupa. — ab. eburnea Closs is merely a West-Chinese variation, in ebumea. 
which the small light spots of the forewings are very much widened, forming two yellowish-white dentate bands, 
the distal one of which flows. Out into a large similar subapical spot. Hindwing with a yellow costal margin 
and anal spot. Abdomen above yellowish-grey with a black median line; the lateral spots are sharply defined. 
— lifuense Rothsch. has the remotest patria: Lifu I. (of the Loyalty Is.); described from a single <$. — fasciatus lifuense. 
fasciaius.
