CECHENENA. Bv Dr. A. Seitz. 
70. Genus: Ceclienena R. & J. 
The 13 forms of this genus have been described by very different generic names. The flat oblique stripes 
crossing the forewing, which are often noticeable in the Sphingidae from all parts of the world, are verv 
conspicuously developed in some species of this genus. Very little is known of the larvae. That of C. lineosa 
has a particularly large and complicated sham-eye and uses to draw in its head with the 3 first segments very 
deep into the strongly inflated 4th segment, so that an entirely round, thick, large-eyed animal’s head is copied. 
The genus was characterized in Vol. II, p. 260. Only 1 species (minor) touches the extreme south-eastern part 
of the palaearctic region. 
mirabilis. C. mirabilis Btlr. (68 b) entirely lacks the usual oblique stripes; at once recognizable by the dark bluish 
or greyish green forewings traversed by irregular and divided blackish cross-bands. Thorax likewise green 
laterally covered with a reddish-white fur. Abdomen and hindwing earth-brown, hindwing in the basal 
half and before the margin black. From North-West India, but not yet taken in palaearctic districts. 
aegrota. C. aegrota Btlr. (= catori Rothsch., chimaera Rothsch., velata Hmps.) (68 b) is considerably larger, the 
forewing brown instead of green, otherwise like mirabilis with dark cross-bands which, however, are duller, more 
indistinct; hindwing black with a curved, proximally notched, dull ochreous submarginal band. Widely 
transpaci- distributed, from North India across Malacca to Java and Borneo. transpacifica Clk., described as Xylophones, 
fim. probably a distinct species, but very near to aegrota , though of a lighter and brighter colouring, the bands on 
the forewing more distinct. — aegrota is not common. 
helops. C. helops Wkr. (= orientalis Fldr.). In this beautiful species white transverse markings are inserted 
between the very dull dark transverse bands of the forewings, and the stigma of the forewing is visible, whilst 
it is absent in the preceding species. Hindwing quite black excepting the duller tinted margins, only the anal 
papuana. portion being dingy white. It differs from papuana R.&.J. (68 a), from New Guinea and New Pomerania, 
particularly in the darker fringes and the undulate oblique streak through the apex of the fore wing being black 
instead of white. Besides, the margin of the forewing in papuana, is somewhat notched (in helops smooth) and 
interposita. the apex is more pointed and more produced. interposita J. & T ., from Ceram, resembles typical helops above, 
but it shows the ochreous, pink-tinted under surface of papuana. 
minor. C. minor Btlr. (= striata Rothsch.) (Vol. II, pi. 42 d) is the only species penetrating into the palaearctic 
region and is remarkably similar to Theretra-iorms from the japonica- and pinastrina- groups, though its abdomen 
is not laterally golden as in these forms. The median (white) oblique stripe of the forewing is expanded in the 
apex into a distinct large white apical spot, whereby the species is somew'hat similar to Tli. nessus with which 
olivacens. it flies, but which is mostly considerably larger (often almost twice as large). - olivacens Mell, from Kwang- 
tung, shows a clear olive colouring of the head, thorax, palpal apex, and costal area of the forewing; the light 
oblique band and marginal area of the forewing and the dorsal stripe of the abdomen are more distinctly outlined. 
Larva young green, full-grown brown with a very much thickened 4th ring into which the very pointed 
anterior portion is drawn in, when the insect is disquieted, so that the frightening eve, the pupil-spot of which 
is somewhat cross-eyed, assumes a threatening expression. Below the subdorsal line darker oblique shadows. On 
Ampelopsis and Actinidia. The imagines visit blossoms in the evening. From North India across Siam and 
China to Japan and Formosa, at some places in India common. 
lineosa. C. lineosa Wkr. (= major Btlr.) (68 a) is similar to minor , but larger, across the thorax a white median 
stripe, the dull white oblique streak through the forewing in the apex not so distinctly expanded, the ochreous 
band of the hindwing in the typical form expanded towards the costa. From the Himalaya and Assam. - In 
subangu- subangustata Rothsch., from Sumatra, the yellow band of the hindwing is not so much expanded towards the 
stdta. cos t a — - Larva chocolate-brown with a large sham-eye squinting forward and a reticular marking similar to 
the skin of a snake, the longitudinal and oblique stripes being indistinct. On Ternstroemiaceae such as Actinidia 
fulvicoma and Saurauja tristyla. — It is one of the most common species of this genus. 
pollux. C. pollux Bsd. (= pseudonessus Rothsch.) (68 b) is similar to lineosa, but the forewing more pointed and 
quite dark green which colour extinguishes also the white oblique stripe of lineosa, so that only the dark oblique 
stripes are distinct. Hindwing black with a dull orange anteterminal band and some yellow at the base. Java, 
Sumatra, and Philippine Is.; very rare. — Another form of this lepidopteron, from South-Western Sumatra, 
rubrescens. was named: -— f. rubrescens Clk. 
scottl. C. scotti Rothsch., from Massuri in the Himalaya, is unknown to me in nature. It is unlike any species 
known. Head deep green, edged with pinkish-white. Thorax and base of abdomen deep green, abdomen itself 
more pale olive; on the dorsum two broad, pinkish silver-grey bands and a broad green median band. Fore wing 
reddish greyish-green, basal half below the stigma flesh-coloured pink; basal portion of wing dark green as far 
as 3 / 5 ; stigma a black dot. Below the green area there are two indistinct, partly obsolete, dull olive oblique 
stripes, from the inner margin to the apex an intense double oblique olive band, and behind it in the marginal 
area several dark green, faint undulate lines. Hindwing inside black, towards the margin pinkish-yellow, 
darkened by black. —-
