SPHINGID.E. 43 



base of the wings is a ratlier dense tuft of long white, deep 

 black, and pale blue scales; and the base of the whitish 

 longitudinal stripe is tinged with glossy blue. 



Hind wings \-ellowish white or pinkish white, with the 

 basal portion broadly deep black, and a narrow black trans- 

 verse band just within the hind margin. In the intermediate 

 pale space is a large cloud of bright pink, shaded oft' so as to 

 tinge a great part of this space, except towards the dorsal 

 margin, where it remains white; hind margin tinged with 

 brownish grey ; cilia whitish. 



Underside of the fore wings broadly olive-brown along the 

 costal and dorsal margins, pale bluish grey along the hind 

 margin, and having the long middle space yellowish white, 

 tinged with olive. At the end of the discal cell is an elon- 

 gated black spot, not visible above. Hind wings with the 

 basal half pale olive followed by a broad band of pinkish 

 white ; hind margin broadly bluish grey, and having a brown 

 blotch near the white anal angle. Body beneath pale olive- 

 brown with white transverse lines; legs olive-bi'own and 

 white. Sexes very similar in all respects. 



A very constant species in colour and markings, but the 

 pink colouring on the hind wings is occasionally much 

 reduced in area, and, more rarely, specimens occur insuffi- 

 ciently covered with scales, and having the dark markings 

 obscure and the pale spaces smoky. 



On the wing in May, June, July, and August, and occa- 

 sionally in October. 



Larva nearly three inches long. Moderately plump and 

 cylindrical, except that the thoracic segments taper con- 

 siderably to the rather small head ; caudal horn rough with 

 minute bristly points, curved back over the anal flap. 

 Hinder portions of the segments divided by wrinkles ; pro- 

 legs fringed by a few bristles. Head pinkish or purplish 

 pink, with a black band over the mouth. Colour of the back 

 and sides olive-green, sometimes varying towards olive-brown,
