260 SPHINGIDiE. 



is reduced to a very narrow strip. The fan-tail is found in 

 both sexes of a number of genera, sometimes only in the o 

 (Eurypteryx) ; it is a Sesiid character, indicated occasionally 

 only by three small tufts (Nephele <$<$). The scent-organ of 

 the anterior coxa is sometimes strongly developed (Chromis). 

 The mid- and hind coxal merum is simply carinate or sub- 

 angulate ; but the large sharp tooth found in Sesia and allies 

 appears also in this tribe (Macroglossum and allies), although 

 the hind coxal merum is never as strongly produced as in 

 Sesia " (Roths. & Jord., I.e. 1903). 



The typical Philampeline moth has the fore wing marked 

 with curved bands and triangles of various shades ; where 

 these markings are replaced by longitudinal or oblique stripes, 

 recalling the markings of Chcerocampine moths, the outer 

 margin is usually sinuate or the apex falcate-truncate 

 (Panacra) . 



Larva. — The larvae of this tribe fall roughly into two groups :: 

 first, those resembling the larvae of the tribe Sesiini (Macro- 

 glossum and allies) ; second, those resembling Chcerocampine 

 larvae, with body tapering strongly front ad and the anterior 

 segments retractile. Subdorsal ocelli or an ocellus-like marking- 

 round the spiracle of segment 5 occur in the second group. 

 The head is always round and small except in Angonyx, 

 where it is large and semi-elliptical. The surface is shining 

 or dull, and usually smooth, though tuberculate in Ampelo- 

 phaga ; in Macroglossum bombylans there is a subdorsal line 

 of spine-like tubercles. The colour is commonly green, but 

 dimorphism and polymorphism occur. 



Pupa. — In several genera (Nephele, Panacra, Macro- 

 glossum) basal part of tongue in a laterally flattened sheath 

 projecting frontad and ventrad, as in many Chcerocampine 

 pupae. The three anal segments are sometimes fused into 

 a cone or a hemisphere, the base of which fits into the deeply 

 undercut hind margin of segment 11 {Acosmeryx). Tongue 

 reaches tip of wing-case ; coxal piece present or wanting. 

 Surface shining or dull, and smooth ; no sculpturing on seg- 

 ment 4 or ante-spiracular ridges. The colour is of various 

 shades, with stripes, spots or mottling, except in Angonyx, 

 which is the only uniformly coloured pupa. 



Habits. — The food-plants belong to a large number of 

 families, Rubiaceae, Ampelideae and Aroideae being most com- 

 monly selected. The eggs are laid singly on the underside 

 of a leaf, where the young larva lies stretched straight out. 

 In later instars the same position is adopted, or the head 

 and anterior segments are bent up at right angles to the rest 

 of the body. The larvae of some genera adopt a defensive 

 attitude, which gives them a snake-like appearance (Acosmeryx,.
