tS4 SPHINGID^. 



area have a brown line above and below the base, those in the 

 lateral and spiracular area have the base completely ringed 

 with brown. Broad oblique stripes starting above the spiracles 

 on 5 to 11 and extending backwards and slightly upwards to 

 the hind margin of each segment, blue near the spiracle 

 becoming paler and then white at the hind margin, the whole 

 edged narrowly above and below by brownish-purple. Horn, 

 and the cone from which it rises, blue with scattered black 

 tubercles ; the tubercles on anal flap and claspers shining 

 black. Legs and prolegs green. Spiracles elliptical in shape, 

 with a narrow central slit widening at the top and bottom, 

 the whole cream-coloured and ringed with green. Length 

 about 90 mm. ; longest spine 4 mm. 



Pupa. — Slender, with a free tongue-sheath ; this is evenly 

 arched and recurved basad, but not into a spiral; the tube 

 rather thin, with a bulbous end ; tongue reaching tip of wing- 

 case ; antenna in both sexes slightly longer than fore leg 

 and considerably shorter than mid-leg ; no coxal piece. 

 Surface smooth and shining ; tongue-sheath coarsely wrinkled 

 with parallel transverse ridges ; the depressions between 

 the ridges a good deal narrower than the ridges themselves ; 

 head and thorax with the surface broken by shallow uneven 

 cracks ; no sculpturing on segment 4 ; segments 5, 6 and 7 

 sparsely and not very coarsely pitted, the hind margins 

 nearly smooth ; ante -spiracular ridges on 9 in the form of three 

 very narrow ridges separated by wide, smooth, polished furrows, 

 the ridges not extending below the spiracles. Spiracles flat, 

 the central slit bordered by a coarse flattened lip on each 

 side. Cremaster a thin oval or rounded plate, markedly 

 constricted at base, and with two very short blunt teeth at 

 tip ; dorsal surface flat, ventral slightly concave, both surfaces 

 coarsely pitted. Colour reddish-brown, darker in the dorsal 

 area when fresh ; nearly black when old : spiracles black. 

 Length 57-62 mm. 



Habits. — Eggs laid singly on underside of leaves of Callicarpa 

 arbor ea Roxb., family Verbenaceae. Eggs and larvae found 

 on both saplings and large trees, eggs in June and larvae 

 in July and August. 



The first specimen found was in the 3rd ins tar, and its 

 appearance was so peculiar that we were uncertain of its 

 identity. The yellow colour of the body, the blue spines 

 and the thin whip-like horn were quite unlike any other 

 sphingid larva we had seen. We later found three eggs on 

 the same food-plant, and the larvae which hatched from these 

 were typical of many sphingid larvae in the 1st instar. After 

 the first moult the colour, spines and the shape of the horn 

 showed these larvae to be identical with the one first discovered, 

 and the latter to be a sphingid larva. The larvae are sluggish
