26 SPHINX OONVOLVULI. 



cular region, and being covered with regular transverse 

 lines of whitish-grey dots on a brownish- grey ground ; 

 the oval black spiracles were deeply sunk each within 

 a large rounded shining spot of blackish ; the broad, 

 whitish, inflated subspiracular stripe, was tolerably 

 regular along the thoracic segments, but from the fifth 

 segment it was festooned along in a puckered and 

 tortuous course to the anal flap, followed beneath on 

 most segments by a group of blotches and dots of a 

 similar whiteness; the back of the second segment 

 was glossy ; the anterior legs were black and shining, 

 also the caudal horn,* the anal flap was greyish - 

 ochreous; the ventral and anal prolegs were of the 

 ground colour, ringed with dull orange-red near their 

 extremities, which were tipped with dark brown hooks ; 

 the belly had a fine ventral line rather darker than the 

 ground, which was thickly freckled over with a paler 

 tint of the same. 



The pupa measured two inches and eleven-sixteenths 

 in length, and five-eighths of an inch in diameter ; its 

 stout proboscis projected a quarter of an inch from the 

 body, bent downwards at a slight angle for little more 

 than half an inch, and then curved round upwards for 

 half the distance towards the underside of the thorax, 

 with which it was in contact near its blunt, rounded 

 extremity. The various parts of the imago within were 

 all remarkably well shown, yet gently rounded off at 

 the prominences, the wing-covers long in proportion, 

 the anal spike short, blunt, and roughish, the proboscis 

 delicately corrugated or ringed. Each segment of the 

 abdomen had on the back a narrow transverse band of 

 roughness at its beginning, the rest of the surface 

 smooth and shining; the colour was a light rich 

 mahogany-brown, darker on the head, thorax and pro- 

 boscis, and on the last two segments ; the leg-, antenna- 

 and wing-cases being the palest portions. (W. B., 4, 

 73; E.M.M. IX, 286.) 



* The horn seems to vary in colour. Boisduval says " it is either 

 fawn above and black beneath, or ferruginous, or of a rusty-red. — W. B.
