2. Group: Sphingidae semanophorae. 
371 
The unsealed bare inside of the first palpal joint is set with sensorial hairs which are generally localised 
on a ,,basal spot“. 
Subfamily: Sesiinae. 
Mesonotum distinctly tufted or the palpi laterally angular. Chiefly American genera, the only genus 
occurring in the Ethiopian Region also in India. 
34. Genus: CepllOilOtles Him. (Potidaea Wllgr.). 
Antennae in both sexes strongly club-shaped. Wings hyaline, the greatest part without scales, fresh 
specimens clothed with easily evanescent hair-scales. Twelve species, most of which occur in the Indo-Australian 
Region. 
C. apus Bsdv. Anterior tibiae without terminal thorns; abdomen green, with a hemochrome belt on apus. 
the 5 th segment, the following rings shaded with hemochrome. Tail brown, lateral tufts black. Body beneath 
orange-red, palpi yellowish-white. The first tarsal joint of the forelegs with a dense row of vertically projecting 
thorns. Bourbon, Mauritius. 
C. trochihss Guer. (= cynniris Guer., cyaniris Ky.). Anterior tibiae without terminal thorns, abdomen trochilus. 
above green, of a faded tan-colour, particularly at the end, without the red belt, chest below yellow. Mauritius. 
C. hylas L. Anterior tibiae without terminal thorns, chest below white, hardly yellowish, the last hylas. 
abdominal segments beneath in the centre blackish. The typical form only occurs in the Indian Region; in 
the whole of Africa to the south of the Sahara and in Madagascar we meet w r ith the race virescens Wllgr. virescens. 
( — confinis Bsdv.) (64 e) which is only discernible by the differences of the sexual armature and which numbers 
among the most common species. 
C. leucogaster R. 6c J . is easily discernible from hylas by the abdomen being at the end beneath all white, leucogaster. 
the red belt above being only distinct on the sides. The black margin of the forewing is somewhat narrower 
at the apex, otherwise as hylas. Madagascar. 
Subfamily: Philampelinae. 
Thorax not high-tufted, palpi not laterally angular. Of the two tribes the Philampelicae do not occur 
in the region, whereas the Nephelicae are represented by numerous genera. 
35. Genus: Deilcplftila Lasp. (=Elpenor Oken, Choerocampa Dup., Metopsilus Dune.). 
Eyes without cilia, last segment of antenna with long scales, spurs of middle tibiae of unequal length, 
margin of forewing not dentate. Pulvillus and paronychium present, anterior tibiae spined. Of the tiny thorns 
at the end of each abdominal tergit those of the front row are longer than broad. 
D. nerii L. (Vol. II, p. 250 pi. 39 c). This species having been described and figured already in the palearctic nerii. 
part also occurs in the Ethiopian and Madagassic Region and is very common. — The form infemelutea Saahn., infemclutea. 
described from Madagascar, but also occurring elsewhere together with the typical form with which it is 
connected by transitions, are specimens in which the under surface is richly coloured orange and red-brown, 
without any green marking. 
36. Genus: Maasseiiia Saahn. 
Thorns of the abdominal segmental margins as in the preceding species, last palpal segment scaled, 
long; distal margin of forewing somewhat dentate; pidvillus and paronychium present, anterior tibiae without 
terminal thorns. Separated from N ephele etc. by thinner antennae and the dentate margin of the fore wing. 
M. heydeni Saahn. (64 d). Forewing violettish-brown, with brown shadows and transverse lines; stigma heydeni. 
dentate, crescentiform pale gold. Hindwing brown. Marginal area in both wings beneath darker, dentately 
defined. Madagascar. — In comorana R. 6c J . the dark band in the forewing is more distinctly marked from comorana. 
the costal margin to the tornus, the silvery stigma is larger, the proximal three quarters of the hindwing are 
somewhat greyer. On the w T hole a somewhat smaller race. Grand Comore,
