■ SPHINGID.-E. 53 



divided by a black line down every nervure. Hind margin pale 

 greyish brown, dusted with darker atoms ; cilia silvery-white. 

 Sexes alike, but female slightly the larger and stouter. 



Underside of the fore wings dingy pale brown to the 

 middle, beyond which is a broad oblique band of dull orange 

 dusted with black atoms, extending to the apex ; hind 

 marginal space broadly tinged with a bluish bloom and 

 margined inwardly with brown ; central spot whitish. 

 Hmd wings dusky dull orange or reddish, dusted with black 

 or brown atoms, with the margins broadly brown, and across 

 the middle, three parallel, indented and curved, grey trans- 

 verse lines. Body and legs, beneath, whitish brown. 



Apparently not at all variable except in size. 



On the wing in September and October, and, very rarely, 

 in the spring, probably after hybernation in the imago state. 



Larva, three inches in length, moderately stout and cylin- 

 drical from the fourth segment to the tail, but tapering very 

 much to the head, which with the next two segments is 

 drawn in during repose. The head is small, roundish in 

 outline, but flattened in front, dark brown, lobes edged with 

 blackish. Twelfth segment with a short, thick, pointed, 

 dark brown horn on the back, pointing obliquely backwards 

 but slightly curved up. Body of a pale umbreous brown 

 closely covered with dark brown dots arranged in lines, 

 except in the cases of the first three body-segments, which 

 are paler and the lines of dots few. Anal flap light yellowish- 

 brown. On each side of the fifth and sixth segments is a 

 conspicuous black ring-spot, with the centre white, and out- 

 side it a ring of yellow. The white centre is not always 

 round or quite central, and is sometimes somewhat divided. 

 Beyond these spots a yellowish subdorsal line extends to the 

 twelfth segment, and on the thirteenth spreads into a broad 

 yellowish-brown blotch which attains the anal flap. Spiracles 

 bluish, ringed with black, and having above each an orange 

 spot. Legs and pro-legs dark brown.
