a) Tribus Philampelicae. 
40. Genus: Tmostouia B. & J. 
This tribe is quite American except one species found in the Sandwich Is. When the species was 
published, only 1 specimen was known, having been captured at an altitude of 2000 ft.; it is in the collection 
of the British Museum. 
T. smaragditis Meyr. Shape similar to that of Deilephila or Gelerio ; thorax, forewing and anterior smaragditis. 
portion of the abdominal dorsum green, hindwing purple brown with a slight violet reflection. From the north¬ 
eastern Sandwich I. Kauai. A male. Judging from the habitus the insect belongs to the American fauna. 
b) Tribus Neplielicae. 
In contrast with the preceding tribe, the Nephelicae are almost entirely confined to the Old World; 
only in the north a few small species also invade the boreal parts of America, but without reaching to South 
America. The group is very well represented by the genus Nephele in the Ethiopian region, and the polytypical 
genus Macroylossum is distributed over the entire Old World, as far as the temperate and warm climate reaches. 
41. Genus: Chromis Hbn. 
The Chromis exhibit the elegant structure of the Sphingidae in the most typical form, the smoothly 
margined, equable shapes of the wings and the fish-shaped, posteriorly tapering body. But few forms belong to 
it, being confined to the South-Asiatic and Australian islands, where they prefer the sea-coasts and fly to the 
lights of ships; they were even caught on very small, low atolls. 
Ch. erofus Or. (andamanensis Ky.) differs from the figured eras Bsd. (= erotus Wkr. nec Cr., erotoides erotus. 
Wllgr., sapor Kocli, eroides Koch) (62 b) chiefly in the broader marginal band of the orange hindwing which eras • 
varies individually, though in eastern specimens it does not attain the width of the western $$. Moreover, 
the underside of the wings and body is mostly more reddish brown in the easternmore eras than in typical 
erotus. The range of the latter form extends from Ceylon across the Andamans and Sunda Is. to Celebes and 
Sumba. Farther to the east it is followed by the form eras extending from Australia across the South Sea to 
the Philippines and Marshall Is. in the north and the Society Is. in the east. — Larva either green or brown, 
with a slightly curved horn of medium length. From the 3rd to the 10th rings there are on the sides 8 equally 
sized ocelli being blue in the green larvae and green in the brown ones, with white centres. On the sides light oblique 
shadows, and from the 4th ocellus to the last segment a light lateral line. Presumably on species of Vitis. 
Ch. heliodes Meyr. (= alberti Bothsch.) (62 e) is similar to erotus, smaller, the forewing more distinctly heliodes. 
marked; the marginal band of the hindwing is broader at the apex than at the anal angle (in erotus the reverse). 
On the shoulders there are on the thorax two white spots. New Guinea and the islands situate to the south¬ 
east of it. 
Ch. meeki Bothsch. (62 e) is quite similar to heliodes, but the body and forewings are more of a greenish meeki. 
tint, the marginal band of the hindwing inside irregularly defined. New Guinea. 
42. Genus: Deilephila Lasp. 
This genus being composed of 7 very graceful species is purely Indo-Australian save one species. 
As to the genus itself we refer to Vol. II, p. 249—250. 
D. nerii L. (Vol. II, pi. 39 c) varies but very little in spite of its enormous range extending from Central nerii. 
Europe to the south as far as the Cape of Good Hope and in the east as far as India and Ceylon; it varies 
noticeably only in the size and in the tint of the discal oblique band which may turn from light grey and 
whitish to yellow and even to a beautiful pink shade; besides, the shade of the ground-colour may also differ 
slightly according to the season. — ab. ffifernelufea Saabn. are specimens with a bright honey-coloured under infeme- 
surface; from Madagascar, but they also occur in other places. We refer also to Vol. II, p. 250 and Vol. XIV, lutea. 
p. 371. 
D. hypothous Cr. (63 a) is at once discernible from nerii by the much darker colouring, the beautiful hypothous. 
green of nerii being darkened into an olive-tinted brown. The light antemarginal stripe of the hindwing above 
is almost straight. It is distributed from North India to Ceylon in the south, and across the archipelago to 
the Key Is. and the Timor-Laut group: in Ceylon *) and the Sunda Is. it is in some places and years extremely 
*) When in the Boer-war in 1901 the camps of prisoners in Ceylon were surrounded by arc-lamps, numerous Sphinges 
(but chiefly D. hypothous) appeared in such swarms that the masts of the lamps on to which they settled were so crammed 
with them that the newcomers seeking a resting-place pushed away those that had already settled down.
